Cette étude se focalise sur différentes méthodes utilisées pour l’analyse phonologique de la parole aphasique. Nous comparons des tâches expérimentales de répétition et de dénomination d’image, des tâches d’élicitation semi-structurées et de la parole naturelle. Nous montrons que le type de mots rencontrés, le type de consonnes ou encore le nombre de productions diffèrent selon la tâche. Si les protocoles expérimentaux permettent d’obtenir toutes les cibles voulues, les tâches d’élicitation semi-structurée permettent d’avoir un plus grand nombre d’occurrences de sons et (...) de mots et des productions subissant des transformations différentes.

Two experiments are reported that employed think-aloud methods to test predictions concerning relevance effects and rationalisation processes derivable from Evans' (1996) heuristic-analytic theory of the selection task. Evans' account proposes that card selections are triggered by relevance-determining heuristics, with analytic processing serving merely to rationalise heuristically cued decisions. As such, selected cards should be associated with more references to both their facing and their hidden sides than rejected cards, which are not subjected to analytic rationalisation. Experiment 1 used a (...) standard selection-task paradigm, with negative components permuted through abstract conditional rules. Support was found for all heuristic-analytic predictions. This evidence was shown to be robust in Experiment 2, where "select - don't select" decisions were enforced for all cards. Both experiments also clarify the role played by secondary heuristics in cueing the consideration of hidden card values during rationalisation. We suggest that whilst Evans' heuristic-analytic model and Oaksford and Chater's (e.g., 2003) optimal data selection model can provide compelling accounts of our protocol findings, the mental models theory fares less well as an explanation of our full dataset.

Background: Neurotypical young adults show task-based modulation and stability of their eye movements across tasks. This study aimed to determine whether persons with aphasia (PWA) modulate their eye movements and show stability across tasks similarly to control participants. Methods: Forty-eight PWA and age-matched control participants completed four eye-tracking tasks: scene search, scene memorization, text-reading, and pseudo-reading. Results: Main effects of task emerged for mean fixation duration, saccade amplitude, and standard deviations of each, demonstrating task-based modulation of eye (...) movements. Group by task interactions indicated that PWA produced shorter fixations relative to controls. This effect was most pronounced for scene memorization and for individuals who recently suffered a stroke. PWA produced longer fixations, shorter saccades, and less variable eye movements in reading tasks compared to controls. Three-way interactions of group, aphasia subtype, and task also emerged. Text-reading and scene memorization were particularly effective at distinguishing aphasia subtype. Persons with anomic aphasia showed a reduction in reading saccade amplitudes relative to their respective control group and other PWA. Persons with conduction/Wernicke’s aphasia produced shorter scene memorization fixations relative to controls or PWA of other subtypes, suggesting a memorization specific effect. Positive correlations across most tasks emerged for fixation duration and did not significantly differ between controls and PWA. Conclusions: PWA generally produced shorter fixations and smaller saccades relative to controls particularly in scene memorization and text-reading respectively. The effect was most pronounced recently after a stroke. Selectively in reading tasks, PWA produced longer fixations and shorter saccades relative to controls, consistent with reading difficulty. PWA showed task-based modulation of eye movements, though the pattern of results was somewhat abnormal relative to controls. All subtypes of PWA also demonstrated task-based modulation of eye movements. However, persons with anomic aphasia showed reduced modulation of saccade amplitude and smaller reading saccades, possibly to improve reading comprehension. Controls and PWA generally produced stabile fixation durations across tasks and did not differ in their relationship across tasks. Overall, these results suggest there is potential to differentiate among PWA with varying subtypes and from controls using eye movement measures of task-based modulation, especially reading and scene memorization tasks.

Background Analysis of aphasic narratives can be a challenge for clinicians. Previous studies have mainly employed measures that categorized speech samples at the word level. They included quantification of the use and misuse of different word classes, presence and absence of narrative contents and errors, paraphasias, and perseverations, as well as morphological structures and errors within a narrative. In other words, a great amount of research has been conducted in the aphasiology literature focusing on micro-linguistic structures of oral narratives. Aspects (...) of macro- linguistic structures, such as the analysis of content information by a speaker, consistency of using cohesive devices to present information within a narrative, and order of presenting information necessary to form a coherent discourse, have not been extensively investigated. The current investigation proposes a clinical analytic system to target three aspects of macro-linguistic structures in narratives among speakers with aphasia. Specifically, (1) the presence of search events (i.e., the mentioning of key events that allow the listener to understand; Capilouto, Wright, &Wagovich, 2006) within a narrative, (2) the sequence of the mentioned events, and (3) the informativeness (i.e., the fulfillment of lexical items that allow the user to understand what the event is detailing) of the event contents, were focused in the proposed framework. Method Ten controls transcripts from were selected from the AphasiaBank (MacWhinney, Fromm, Forbes, & Holland, 2011). Three narrative tasks, including sequential picture description of ‘Refused Umbrella’, procedural narrative of making a ‘Peanut Butter and Jelly Sandwich’, and telling of ‘Cinderella’ story, were used to establish normative data for the basis of analysis. Specifically, the Search Events (e) and Informative Words (i) used by at least 70% of the speakers were listed for each genre. The sequential order of mentioning the Search Events, i.e., common order of events in 90% of the speakers, (s.total) was determined. Twelve speakers with aphasia (nine fluent and three non-fluent) were recruited and administered the Western Aphasia Battery and Object and Action Naming Battery. Their performance in the above three discourse tasks were orthographically transcribed and analyzed using the following measures: e.total, e.matched with norm, e.missed, e.irrlevant, e.extra, s.total, i.pb&j, i.umbr, i.cind, and i.total. Three samples were randomly chosen to be re-analyzed for inter- and intra-rater reliability. Results Results of an independent t-test suggested significant differences between the fluent and non-fluent subjects in sequential order of Search Events for all genres (s.total) and i.total, suggesting sensitivity of this framework to differentiate between the two fluency groups. Results of Pearson product-moment correlations revealed significant relation between Informative Words and WAB spontaneous speech scores, AQ, as well as OAB scores, for both aphasic groups. The mean value of coefficients for intra-rater reliability (0.992), with significant correlations on e.match, e.miss, and e.extra, was higher than that of inter-rater reliability (0.897). Discussion Based on our preliminary results, this objective framework allowed clinical evaluation of impairment in macro-linguistic structures present in aphasic discourse. Further extension should involve more subjects encompassing a wider range of severity with different types of aphasia. (shrink)

The development of medicine is based on reliable medical research. This is a process that must be planned in detail and performed in accordance with the accepted study protocol, as any negligence – even a small one – or deviation from the protocol may result in distorted research results and – in consequence – to false conclusions. One of the key stages of research is the selection of the appropriate methodology, particularly in terms of tests that verify the posed hypotheses. (...) Each statistical method has a set of assumptions that have to be met in order for the method to be used. This paper explains why the appropriate selection of methods, verification of the required assumptions, and correct graphical representation of the obtained results are so important from the practical perspective.

It is a well-acknowledged fact in legal translation studies that when searching for terminological equivalents, translators should make use of comparative conceptual analysis. Thus, legal translation trainees should be equipped with the necessary tools to carry out such analysis, but the question remains: are they? This paper is a follow-up to a study published in 2017, where modified think aloud protocols were used to explore the following research question: to what degree are university students doing a course in legal and (...) economic translation able to apply the methods of comparative conceptual analysis to translation of terms not accounted for sufficiently in legal dictionaries or terms with no straightforward equivalents. The results showed that major issues involve non-linearity of the analysis carried out and insufficient use of the resources available. The present study involves a different group of 29 BA students of the same course two years later, who were assigned the same task. As the retrospective protocols fail to simulate real-life conditions, this study uses screen recording and keystroke logging to track the processes leading to the identification of the conceptual equivalent in a more detailed and less subject-dependent manner. The results suggest that the steps most challenging for students include identification of relevant features defining the source and target language concepts, comparison of these features and selection, or creation, of an equivalent term reflecting the results of the analysis. Students also frequently show Google-driven searching, which influences the order of the steps performed in their analyses and the sources used. To address these challenges, translation training should include a range of tailor-made exercises focusing on the critical steps of the analysis as well as on improving web searching skills.

IntroductionIncorporating technology in cognitive interventions represents an innovation, making them more accessible, flexible, and cost-effective. This will not be feasible without adequate user-technology fit. Bearing in mind the importance of developing cognitive interventions whose technology is appropriate for elderly people with cognitive impairment, the objective of this systematic review was to find evidence about usability and user experience measurements and features of stimulation, training, and cognitive rehabilitation technologies for older adults with mild cognitive impairment or dementia.MethodThe Medline, PubMed, Scopus, ScienceDirect, (...) and PsycINFO databases were searched for literature published in the last 10 years, and three researchers independently reviewed potentially eligible studies, following specific inclusion criteria. A systematic review of the studies was conducted, presenting a qualitative synthesis of usability and UX measures with their outcomes, study characteristics and features of the cognitive intervention technologies.ResultsTen studies were selected: five were cognitive stimulation and five were cognitive training. Most of them were computer-based programs with a serious game format. Efficiency and effectiveness were the most frequent measurements used for collecting objective usability data, showing that elderly people with cognitive impairment require more time and help but can complete tasks. Regarding UX or subjective usability data, questionnaires and scales were the most used methods, reporting positive experience despite certain difficulties with the interface in five studies.ConclusionMeasuring usability and UX in cognitive intervention technologies for older adults with MCI or dementia provides an integrated view that can contribute to their development according to the needs and characteristics of the target population. More research is required to include this population group in usability and UX studies, as well as standardized tools and consensus on the relationship of these terms to guarantee the future effectiveness of cognitive intervention technologies.Review registrationThis review was registered in the PROSPERO International Register of Systematic Review Protocols.

Background: The way the death of a dear person is communicated can have a profound impact on the entire bereavement process. The words and expressions that are used to give the tragic news, the characteristics of who communicates it, the physical setting in which the notification is given, the means used (e.g., in person, via phone call, etc.) are just some of the factors that can influence the way survivors face one of the most difficult moments in their lives. Aim: (...) To review the literature on the topic of death notification to verify the state of the art related to this important procedure. Methods: A systematic review was conducted with PRISMA criteria on English-written materials produced from 1966 to 2019. Results: Out of the initial 3,166 titles considered, 65 articles were extracted for this review. Four main themes emerged: 1) protocols and guidelines; 2) emotional reactions of recipients and notifiers; 3) professional figures involved in the notification process; and, 4) types of death. Discussion: The communication of death represents a complex and stressful experience not only for those who receive it but also for those who give it. Alongside the acquisition of a necessary technique and execution methods, the process should involve the selection of notifiers based on personality characteristics and communication styles. Conclusion: Indications for the need of better training and protocols sensitive to different circumstances emerge. Adequate preparation can deeply affect the quality of communication and the effects it produces, both on recipients and on notifiers. In vocational training, more space should be devoted to this demanding task. (shrink)

Aphasia is an acquired impairment of language functions resulting from a brain lesion. It is usually accompanied by deficits in non-linguistic cognitive processes. This study aimed to investigate in patients with aphasia the complex interrelationships between selected cognitive functions: auditory speech comprehension, working memory, and temporal information processing in the millisecond time range. Thirty right-handed subjects aged from 27 to 82 years suffering from post-stroke aphasia participated in the study. Verbal working memory and spatial working memory were assessed with: a (...) receptive verbal test and the Corsi Block-Tapping Test, respectively. Both these WM tests used the forward tasks and backward tasks. Auditory comprehension was assessed by receptive language tests, and TIP efficiency was assessed by auditory perception of temporal order in the millisecond time range. We observed better performance of forward WM tasks than backward ones, independently of the type of material used. Furthermore, the severity of auditory comprehension impairment correlated with the efficiency on both forward and backward VWM tasks and the backward SWM task. Further analysis revealed that TIP plays a crucial role only in the latter task. These results indicate the divergent pattern of interactions between WM and TIP depending on the type of WM tasks. Level of verbal competency appeared to play an important role in both VWM tasks, whereas TIP appeared to be important for SWM, but only on the backward task. (shrink)

Procedures for the selection of subjects for participation in randomized clinical trials--usually formalized as eligibility criteria in the study protocol--have both scientific and ethical implications. In this thesis, I undertake an examination of eligibility criteria at three stages in the genesis and dissemination of medical knowledge: clinical trial protocol, interpretation by investigators, and reporting of study results.In the first chapter, ethical issues in subject selection are reviewed and the main study questions are presented. In the second chapter, the results of (...) an examination of eligibility criteria in two sets of clinical trials, one sponsored by the NSABP, the other sponsored by POG, covering a twenty-year time span are presented. The POG trials had far fewer eligibility criteria than the NSABP studies, suggesting that large numbers of criteria may not be necessary for high quality research. In the third chapter, the impact of subjective eligibility criteria on enrollment and investigator uncertainty is explored. Subjective criteria were associated with more variable enrollment decisions and greater uncertainty. Such criteria represent a threat to the validity, conduct and interpretation of trials and, therefore, should only be included when carefully justified. The fourth chapter examines the accuracy of the reporting of eligibility criteria in sets of corresponding study protocol, methods paper, journal article, and Clinical Alert. Important information is lost at each step in the dissemination of study results. Unnecessary criteria ought to be dropped at a trial's inception; all other criteria must be reported faithfully. The fifth chapter attempts to provide a comprehensive philosophical account of just selection procedures for clinical research using the political philosophy of Michael Walzer. The sixth, and last, chapter, discusses explanatory and pragmatic approaches to clinical trial design, overlapping scientific and ethical concerns related to eligibility criteria, and questions for further study.

Despite the ubiquity of inner speech in our mental lives, methods for objectively assessing inner speech capacities remain underdeveloped. The most common means of assessing inner speech is to present participants with tasks requiring them to silently judge whether two words rhyme. We developed a version of this task to assess the inner speech of a population of patients with aphasia and corresponding language production deficits. As expected, patients’ performance on the silent rhyming task was severely impaired relative (...) to controls. More surprisingly, however, patients’ performance on this task did not correlate with their performance on a variety of other standard tests of overt language abilities. In particular, patients who were generally unimpaired in their abilities to overtly name objects during confrontation naming tasks, and who could reliably judge when two words spoken to them rhymed, were still severely impaired (relative to controls) at completing the silent rhyme task. This seems to suggest that inner speech was more severely impaired in these patients than outer speech. However, these results should also cause us to critically reflect on the relation between inner speech and silent rhyme judgments more generally. (shrink)

Objective—Consultation of another physician is an important method of review of the practice of euthanasia. For the project “support and consultation in euthanasia in Amsterdam” which is aimed at professionalising consultation, a protocol for consultation was developed to support the general practitioners who were going to work as consultants and to ensure uniformity. Participants—Ten experts (including general practitioners who were experienced in euthanasia and consultation, a psychiatrist, a social geriatrician, a professor in health law and a public prosecutor) and (...) the general practitioners who were going to use the protocol. Evidence—There is limited literature on consultation: discursive articles and empirical studies describing the practice of euthanasia. Consensus—An initial draft on the basis of the literature was commented on by the experts and general practitioners in two rounds. Finally, the protocol was amended after it had been used during the training of consultants. Conclusions—The protocol differentiates between steps that are necessary in a consultation and steps that are recommended. Guidelines about four important aspects of consultation were given: independence, expertise, tasks and judgment of the consultant. In 97% of 109 consultations in which the protocol was used the consultant considered the protocol to be useful to a greater or lesser extent. Although this protocol was developed locally, it also employs universal principles. Therefore it can be of use in the development of consultation elsewhere. (shrink)

Feature selection is a widely studied technique whose goal is to reduce the dimensionality of the problem by removing irrelevant features. It has multiple benefits, such as improved efficacy, efficiency and interpretability of almost any type of machine learning model. Feature selection techniques may be divided into three main categories, depending on the process used to remove the features known as Filter, Wrapper and Embedded. Embedded methods are usually the preferred feature selection method that efficiently obtains a selection of (...) the most relevant features of the model. However, not all models support an embedded feature selection that forces the use of a different method, reducing the efficiency and reliability of the selection. Neural networks are an example of a model that does not support embedded feature selection. As neural networks have shown to provide remarkable results in multiple scenarios such as classification and regression, sometimes in an ensemble with a model that includes an embedded feature selection, we attempt to embed a feature selection process with a general-purpose methodology. In this work, we propose a novel general-purpose layer for neural networks that removes the influence of irrelevant features. The Feature-Aware Drop Layer is included at the top of the neural network and trained during the backpropagation process without any additional parameters. Our methodology is tested with 17 datasets for classification and regression tasks, including data from different fields such as Health, Economic and Environment, among others. The results show remarkable improvements compared to three different feature selection approaches, with reliable, efficient and effective results. (shrink)

In this paper, we derive necessary and sufficient conditions on team based tasks in order for a selection criterion applied to individuals to produce optimal teams. We assume only that individuals have types and that a team’s performance depends on its size and the type composition of its members. We first derive the selection principle which states that if a selection criterion exists, it must rank types by homogeneous team performance, the performance of a team consisting only of that type. (...) We then prove that a selection criterion exists if and only if replacing the team’s lowest ranked type, as measured by homogeneous team performance, with a higher ranked type increases team performance. Finally, we show that the replace the lowest ranked property rules out most common types of team complementarities, including benefits to diverse types and types that fill structural holes. (shrink)

Background: Many people with aphasia and people without brain injury talk to themselves in their heads, i.e., have “inner speech.” Inner speech may be more preserved compared with spoken speech for some people with aphasia and may serve a variety of functions (e.g., emotion regulation), which motivates us to provide a high-fidelity characterization of it. Researchers have used multiple methods to measure this internal phenomenon in the past, which we combine here for the first time in a single study. -/- (...) Aims: We compare performance between individuals with and without aphasia on inner speech tasks that assess inner speech “inthe- moment” to general subjective impressions of inner speech to tease apart the relationship of aphasia severity to inner speech. Methods and Procedures: Twenty people with mild-moderate aphasia and twenty neurotypical controls completed several inner speech tasks, including objective silent rhyme judgements (picture, written, and auditory), subjective reports of inner speech during naming, and subjective rating scales about inner speech experience more generally. -/- Outcomes and Results: In-the-moment inner speech during silent rhyming tasks was associated with aphasia severity only for picture and written rhyming but not auditory rhyming. In-the-moment inner speech reports during silent naming were not associated with aphasia severity, nor were the subjective ratings about general inner speech experience. Individuals with and without aphasia demonstrated a variety of subjective general inner speech experiences, demonstrating heterogeneity of this phenomenon more broadly. -/- Conclusions: Methods of measuring inner speech complement each other and speak to different facets of the inner speech phenomenon, and clinicians and researchers must carefully choose the method(s) that will provide the information about inner speech that they desire.

Personality traits describe dispositions influencing individuals' behavior and performance at work. However, in the context of personnel selection, the use of personality measures has continuously been questioned. To date, research in selection settings has focused uniquely on predicting task performance, missing the opportunity to exploit the potential of personality traits to predict non-task performance. Further, personality is often measured with self-report inventories, which are susceptible to self-distortion. Addressing these gaps, the planned study seeks to design new personality measures (...) to be used in the selection context to predict a wide range of performance criteria. Specifically, we will develop a situational judgment test and a behavior description interview, both assessing Big Five personality traits and Honesty-Humility to systematically compare these new measures with traditional self-report inventories regarding their criterion-related validity to predict four performance criteria: task performance, adaptive performance, organizational citizenship behavior, and counterproductive work behavior. Data will be collected in a simulated selection procedure. Based on power analyses, we aim for 200 employed study participants, who will allow us to contact their supervisors to gather criterion data. The results of this study will shed light on the suitability of different personality measures to predict an expanded range of performance criteria. (shrink)

BackgroundStructured, systematic methods to formulate consensus recommendations, such as the Delphi process or nominal group technique, among others, provide the opportunity to harness the knowledge of experts to support clinical decision making in areas of uncertainty. They are widely used in biomedical research, in particular where disease characteristics or resource limitations mean that high-quality evidence generation is difficult. However, poor reporting of methods used to reach a consensus – for example, not clearly explaining the definition of consensus, or not stating (...) how consensus group panellists were selected – can potentially undermine confidence in this type of research and hinder reproducibility. Our objective is therefore to systematically develop a reporting guideline to help the biomedical research and clinical practice community describe the methods or techniques used to reach consensus in a complete, transparent, and consistent manner.MethodsThe ACCORD project will take place in five stages and follow the EQUATOR Network guidance for the development of reporting guidelines. In Stage 1, a multidisciplinary Steering Committee has been established to lead and coordinate the guideline development process. In Stage 2, a systematic literature review will identify evidence on the quality of the reporting of consensus methodology, to obtain potential items for a reporting checklist. In Stage 3, Delphi methodology will be used to reach consensus regarding the checklist items, first among the Steering Committee, and then among a broader Delphi panel comprising participants with a range of expertise, including patient representatives. In Stage 4, the reporting guideline will be finalised in a consensus meeting, along with the production of an Explanation and Elaboration document. In Stage 5, we plan to publish the reporting guideline and E&E document in open-access journals, supported by presentations at appropriate events. Dissemination of the reporting guideline, including a website linked to social media channels, is crucial for the document to be implemented in practice.DiscussionThe ACCORD reporting guideline will provide a set of minimum items that should be reported about methods used to achieve consensus, including approaches ranging from simple unstructured opinion gatherings to highly structured processes.

Background: Both anxiety and depression in family caregivers of advanced cancer patients are common, and they have a negative influence on both the FCs and the patients. Some studies suggested that a variety of interventions could alleviate the psychological symptoms of FCs. However, there is no consensus on much more effective methods for intervention, and relatively high-quality research is blank in psychological problems of these population in China. The validity of mindfulness-based stress reduction and psychological consultation guided by the needs (...) assessment tool in the psychological status of caregivers will be compared in this study to select a more suitable intervention for the FCs of advanced cancer patients in China.Methods and Analysis: A randomized N-of-1 trial would be conducted at the Cancer Hospital, Chinese Academy of Medical Sciences. Fifty eligible FCs of advanced cancer patients will be recruited, and all will receive three cycles of psychological intervention treatment, with each cycle including both of MBSR and psychological consultation guided by the NST. MBSR and psychological consultation guided by the NST will be compared with each other in each cycle, and the intervention sequence will be based on the random number table generated after the informed consent has been completed. Each treatment period is 2 weeks, and the interval between different treatment cycles or treatment periods is 1 week. The self-reported scales are measured at the beginning and end of each treatment period, including the Self-Rating Anxiety Scale, the Self-Rating Depression Scale, Distress Thermometer, Zarit Burden Interview, Chinese version of the Medical Outcomes Study 12-item Short Form, and Family Carer Satisfaction with Palliative Care scale.Dissemination: The protocol of the study was approved by the Institutional Review Board of the Ethical Committee of the Cancer Hospital, Chinese Academic of Medical Science. The results will be published in a peer-reviewed medical journal. The study is registered at Chinese Clinical Trials Registry with the trial registration number chiCTR2000033707. This study employs an innovative methodological approach on the effectiveness of MBSR and psychological consultation guided by the NST for psychological status of FCs of advanced cancer patients. The findings of the study will be helpful to provide high-quality evidence-based medical data for psychological intervention of FCs of advanced cancer patients, and guide clinicians on best quality treatment recommendations.

BackgroundAt present, adherence to antipsychotic treatment is often poor, leading to the recurrence of symptoms. This increases the likelihood of the patient experiencing disability and thus increases the disease burden for the patient, their family, and society as a whole. However, to date, there is no clear evidence regarding the effect of medication adherence interventions on outcomes for patients with schizophrenia. Moreover, the traditional intervention methods are limited by manpower and resources in low- and middle-income countries. Recent studies have demonstrated (...) that increasing a patient’s level of self-compassion may improve their treatment adherence. Online mental health care interventions have advantages in terms of feasibility and acceptability for patients with schizophrenia. In this regard, a WeChat-based self-compassion training protocol to improve patient treatment adherence was designed in this study and will be evaluated in the future to determine its impact on patients with schizophrenia.MethodsThe protocol for the randomized controlled trial is based on the SPIRIT 2013 statement. This parallel RCT will aim to recruit 392 patients with schizophrenia who will be randomized at a 1:1 ratio into a 3-week intervention or control group. Both groups will receive routine care. The intervention group will also receive WeChat-based self-compassion training, which requires participants to complete three tasks every day, including a reading task, a meditation task, and a self-compassion journal task. The control group will receive WeChat-based psychological health education, which will only require participants to read positive articles about psychological health every day. Medication adherence, self-compassion, stigma, and social support will be measured at baseline, immediately after the intervention, and 3 weeks after the intervention. Program feasibility will be evaluated throughout the course of the study, and acceptability will be measured immediately after the intervention.Expected results:The intervention described here will address the barriers to accessing mental health care for people with schizophrenia, including patients’ desire for independent management, difficulty accessing providers, and concerns about privacy and stigma. The current study provides guidance for clinical nurses to carry out psychological intervention, with the ultimate aim of addressing the problems associated with a shortage of psychological professionals in low- and middle-income countries.

Two studies examined the use of think aloud (TA) protocol as a means for collecting data of cognitive processes during performance in golf. In study 1, TA was employed to examine if different verbalisation (Level 2 or Level 3 TA) instructions influence performance of high and low skilled golfers. Participants performed 30 putts using TA at either Level 2, Level 3, or no verbalization condition. Although Level 3 verbalization produced a higher volume of verbal data than Level 2, TA at (...) either level 2 or 3 did not impair putting performance compared to no verbalization. Study 2 examined the congruence between data collected via TA at Level 3 and cued retrospective recall of cognitive processes during golf performance. Experienced golfers performed six holes of golf whilst engaging in Level 3 TA. After performance, three semi-structured retrospective interviews were conducted (ten minutes after performance, 24 hours after performance and 48 hours after performance). A comparison of the themes identified large discrepancies between the information reported during TA and at interview, with only 38-41% similarity in variables reported to influence decision making on each hole. Both studies suggest TA is a valuable method for recording cognitive processes of individuals during task performance. TA provides richer verbal data regarding decisions than cued retrospective recall, and TA does not negatively impact performance. (shrink)

The central problem which cognitive scientists face in studying thinking is that thinking cannot be observed directly by other people. The traditional solution has been to rely on introspective methods, where individuals observe their own thinking and reflect on its characteristics. In everyday life, the most common technique involves asking people questions about their thinking, knowledge, and strategies. Psychologists have refined the methods for questioning individuals by designing questionnaires and structured interviews. However, these two ways of obtaining information about thinking (...) share two fundamental methodological problems. First, the accuracy of the reports cannot be assessed, because in naturally occurring situations in everyday life the investigator doesn't have any other empirical evidence against which to evaluate the validity of the subjects' reported information. Hence, psychologists are forced to trust the subjects to provide valid information. The second issue concerns whether even those individuals who strive to give accurate reports are able to access and supply valid information on the cognitive processes that mediate their behavior.

Primary progressive aphasia is a clinical syndrome in which patients progressively lose speech and language abilities. Three variants are recognized: logopenic, associated with phonology and/or short-term verbal memory deficits accompanied by left temporo-parietal atrophy; semantic, associated with semantic deficits and anterior temporal lobe atrophy; non-fluent associated with grammar and/or speech-motor deficits and inferior frontal gyrus atrophy. Here, we set out to investigate whether the three variants of PPA can be dissociated based on error patterns in a single language task. (...) We recruited 21 lvPPA, 28 svPPA, and 24 nfvPPA patients, together with 31 healthy controls, and analyzed their performance on an auditory noun-to-verb generation task, which requires auditory analysis of the input, access to and selection of relevant lexical and semantic knowledge, as well as preparation and execution of speech. Task accuracy differed across the three variants and controls, with lvPPA and nfvPPA having the lowest and highest accuracy, respectively. Critically, machine learning analysis of the different error types yielded above-chance classification of patients into their corresponding group. An analysis of the error types revealed clear variant-specific effects: lvPPA patients produced the highest percentage of “not-a-verb” responses and the highest number of semantically related nouns ; in contrast, svPPA patients produced the highest percentage of “unrelated verb” responses and the highest number of light verbs. Taken together, our findings indicate that error patterns in an auditory verb generation task are associated with the breakdown of different neurocognitive mechanisms across PPA variants. Specifically, they corroborate the link between temporo-parietal regions with lexical processing, as well as ATL with semantic processes. These findings illustrate how the analysis of pattern of responses can help PPA phenotyping and heighten diagnostic sensitivity, while providing insights on the neural correlates of different components of language.

The global method safety account of knowledge states that an agent’s true belief that p is safe and qualifies as knowledge if and only if it is formed by method M, such that her beliefs in p and her beliefs in relevantly similar propositions formed by M in all nearby worlds are true. This paper argues that global method safety is too restrictive. First, the agent may not know relevantly similar propositions via M because the belief that (...) p is the only possible outcome of M. Second, there are cases where there is a fine-grained belief that is unsafe and a relevantly similar coarse-grained belief that is safe and where both beliefs are based on the same method M. Third, the reliability of conditional reasoning, a basic belief-forming method, seems to be sensitive to fine-grained contents, as suggested by the wide variation in success rates for thematic versions of the Wason selection task.

Purpose of the article is to present in two parts the selected aspects of application of monetary policy in the euro area pre and post 2008 as well as insitutional adaptations brought by the EU legislator. Methodology/methods In order to better explain these points, the article relies partially on a comparison with the framework and application of the monetary policy by the Federal Reserve as well as on a historic method when outlining the influence of definition of financial stability (...) from the ECB/eurosystem towards other prominent central banks. Scientific aim The article presents selected aspects of the monetary policy in the part of the EU where single currency was introduced in order to outline state of the art governance structure as well as a certain institutional creativity in application of powers conferred upon the central banks by the Treaty on the Functioning of the European Union and Protocol on the Statute of the European System of Central Banks and of the European Central Bank. The goal is to prove the hypothesis of robustness of the framework and present the limits that can only be pushed further by the legislative power. The conclusions confirm on the one hand that the framework of monetary policy based on strong institutional safeguards such as legislative power and independence is very resilient and can prove efficient and creative enough to stabilise an innovative monetary system, however, on the other hand, validate the hypothesis that certain adaptations can only be performed on the basis of a legislative adaptations.

Scientific aim The article presents selected aspects of the monetary policy in the part of the EU where single currency was introduced in order to outline state of the art governance structure as well as a certain institutional creativity in application of powers conferred upon the central banks by the Treaty on the Functioning of the European Union and Protocol on the Statute of the European System of Central Banks and of the European Central Bank. The goal is to prove the hypothesis of robustness of the framework and present the limits that can only be pushed further by the legislative power. The conclusions confirm on the one hand that the framework of monetary policy based on strong institutional safeguards such as legislative power and independence is very resilient and can prove efficient and creative enough to stabilise an innovative monetary system, however, on the other hand, validate the hypothesis that certain adaptations can only be performed on the basis of a legislative adaptations.

The task of the historian is not one of tracing a series of links in a temporal chain; rather, it is his task to analyze a complex pattern of change into the factors which served to make it precisely what it was. The relationship which I therefore take to be fundamental to historiography is ... a relationship of part to whole, not a relationship of antecedent to consequent.Mandelbaum's historian relates the part to the whole, leaving it for the (...) sociologist to relate the antecedent to the consequence.If that is so, then Maigret is first an historian ascertaining and accumulating the subjective meanings that individuals use to produce the facticity of their own lives. And in the course of so doing he discovers the nature of the reality in which the crime occurred. Once he finds his way into the realities of the crime there is time and need for the sociological analysis of antecedent and consequent. To suggest a comparison, Maigret practices in miniature the method of Norbert Elias in that he tries to understand his subjects as they understand themselves. Maigret's is an idiographic science and not a nomethetic one. For this reason Maigret, unlike Holmes, almost never refers to previous cases in the effort to understand the matter at hand.The temptation is to conclude that Maigret is a little like Fernand Braudel in combining history and sociology by turns. But I wonder if there is not a more profound sense in which Maigret, if not all sociologists, is an historian. If we have any knowledge it is of the past, not of the present or the future. Minerva's owl does indeed take wing only at dusk, as Hegel wrote. By the time we have understood the present, it is the past.If Maigret's aim is not the unvarnished truth, that is not because of the constraints of police work but because of the constraints of the world. The irony of Maigret's ethnomethodology is this. Simenon's style is rightly celebrated for its evocation of atmosphere. The apposite analogy occasionally offered is between Simenon's spare and laconic style and Impressionist painting. Simenon does not describe people and places in the Maigret stories but suggests them with a sentence or two. The style is not realism, whatever the effect. As Rafael Koskimies has written, Simenon selects and simplifies. Impressionism is the style of painting that accepts the surface as reality. The play of light and color on the surface of objects is suggested on the surface of the canvas with the texture and color of the paint. If Simenon is an impressionist in his art, Maigret cannot be in his. He does not settle for the surface, but goes inside of it. Once there he learns all he needs to know and all that he can know. The confessions that so frequently occur in the Maigret stories do not confirm his suppositions, but release the tensions of the drama in a catharsis. Finally, if Maigret's Maigret must admit in his Memoirs that he could not in fact go into the detail of every reality personally in the manner described above, it only proves how terribly taxing the method called Verstehen is.To conclude, Maigret has a method, but it is not a recipe that others can follow step-by-step. His method is an orientation to reality and a commitment to understanding in a certain way. To call Maigret's procedure a method requires the definition of “method” to include more than cook books, however brilliant the cook books are. Maigret's method is a part of the context of discovery. Naive realists like Méchin imagine that they live only in the context of justification.Of course, no one's understanding is perfect. Maigret makes mistakes. There are times when an explanation based on behavior would be more accurate and economical. If Simenon does not dwell on Maigret's failures it is clear that Maigret uses other methods, too. The triangulation of a variety of methods is what in fact most of us practice whatever we preach. (shrink)

According to the paradigm of adaptive rationality, successful inference and prediction methods tend to be local and frugal. As a complement to work within this paradigm, we investigate the problem of selecting an optimal combination of prediction methods from a given toolbox of such local methods, in the context of changing environments. These selection methods are called meta-inductive strategies, if they are based on the success-records of the toolbox-methods. No absolutely optimal MI strategy exists—a fact that we call the “revenge (...) of ecological rationality”. Nevertheless one can show that a certain MI strategy exists, called “AW”, which is universally long-run optimal, with provably small short-run losses, in comparison to any set of prediction methods that it can use as input. We call this property universal access-optimality. Local and short-run improvements over AW are possible, but only at the cost of forfeiting universal access-optimality. The last part of the paper includes an empirical study of MI strategies in application to an 8-year-long data set from the Monash University Footy Tipping Competition. (shrink)

The research is focused on the role of two related key concepts, namely variables and data, in the impact evaluations of public projects. A difficult task of the evaluators and researchers is to select the appropriate variables to ensure the best model of reality and satisfy the evaluation methods' needs. Therefore, the paper aims to look at the current knowledge and discuss how variables and data could be best used to connect the evaluation models, the particularities of the intervention (...) with the potential of the advanced quantitative assessment methods. The results emphasise that evaluations operate with data with different levels of granularity, as required by the intervention logic. Structuring data in clusters and categories, performing evaluability assessments are useful in assessing data quality and limitations and improving them. In line with the existing literature, we demonstrate that data accessibility is a key constraint and imposes adjustment of the desired evaluation model to a feasible one. While Big Data and Open Data systems significantly improved data quality in evaluations in recent years, blockchain, as a ledger technology with default features related to decentralisation and security, is expected to bring large benefits to evaluation. For evaluators and policymakers, blockchain potential is an area of further research looking for additional advantages that could enhance the use of quantitative methods. (shrink)

Aim: Participation in classroom physical activity breaks may improve children’s cognition, but few studies have involved adolescents. The primary aim of this study was to examine the effects of classroom-based resistance training with and without cognitive training on adolescents’ cognitive function.Methods: Participants were 97 secondary school students. Four-year 10 classes from one school were included in this four-arm cluster randomized controlled trial. Classes were randomly assigned to the following groups: sedentary control with no cognitive training, sedentary with cognitive training, resistance (...) training without cognitive training, and resistance training with cognitive training. Sessions varied in levels of both cognitive demand and resistance training and were administered three times per week for 4 weeks. Inhibition, cognitive flexibility, episodic memory, on-task behavior, and muscular fitness were assessed at baseline and post-test. Linear mixed models were used to examine changes within and between groups.Results: In comparison with the control group, episodic memory improved significantly in the resistance training without cognitive training group. There were no group-by-time effects for inhibition or cognitive flexibility. Classroom activity breaks both with and without cognitive demand improved participants’ on-task behavior in comparison with the control and sedentary group. The resistance training programs did not lead to improvements in muscular fitness.Conclusion: Participation in body weight resistance training without cognitive training led to selective improvements in episodic memory. No training effects were found for inhibition or cognitive flexibility. A longer study period may be necessary to induce improvements in muscular fitness and associated changes in inhibition and cognitive flexibility.Clinical Trial Registration:https://www.anzctr.org.au/ACTRN12621001341819.aspx, Australian New Zealand Clinical Trials Registry—ACTRN12621001341819.

Conversational interfaces are becoming ubiquitous in an increasing number of application domains as Artificial Intelligence, Natural Language Processing and Machine Learning methods associated with the recognition, understanding and generation of natural language advance by leaps and bounds. However, designing the dialog model of these systems is still a very demanding task requiring a great deal of effort given the number of information sources to be considered related to the analysis of user utterances, interaction context, information repositories, etc. In this (...) paper, we present a general framework for increasing the quality of the system responses by combining a statistical dialog management technique and a deep learning-based intention recognizer that allow replacing the system responses initially selected by the statistical dialog model with other presumably better candidates. This approach is portable to different task-oriented domains, a diversity of methodologies for dialog management and intention estimation techniques. We have evaluated our two-step proposal using two conversational systems, assessed several intention recognition methodologies and used the developed modules to dynamically select the system responses. The results of the evaluation show that the proposed framework achieves satisfactory results by making it possible to reduce the number of non-coherent dialog responses by replacing them by more coherent alternatives.

Over the previous three decades, the area of computer networks has progressed significantly, from traditional static networks to dynamically designed architecture. The primary purpose of software-defined networking is to create an open, programmable network. Conventional network devices, such as routers and switches, may make routing decisions and forward packets; however, SDN divides these components into the Data plane and the Control plane by splitting distinct features away. As a result, switches can only forward packets and cannot make routing decisions; the (...) controller makes routing decisions. OpenFlow is the communication interface between the switches and the controller. It is a protocol that allows the controller to identify the network packet’s path across the switches. This project uses the SDN environment to implement the firefly optimization algorithm to determine the shortest path between two nodes in a network. The firefly optimization algorithm was implemented using Ryu control. The results reveal that using the firefly optimization algorithm improves the selected short path between the source and destination. (shrink)

We present a general theory of series-parallel mental architectures with selectively influenced stochastically non-independent components. A mental architecture is a hypothetical network of processes aimed at performing a task, of which we only observe the overall time it takes under variable parameters of the task. It is usually assumed that the network contains several processes selectively influenced by different experimental factors, and then the question is asked as to how these processes are arranged within the network, e.g., whether (...) they are concurrent or sequential. One way of doing this is to consider the distribution functions for the overall processing time and compute certain linear combinations thereof (interaction contrasts). The theory of selective influences in psychology can be viewed as a special application of the interdisciplinary theory of (non)contextuality having its origins and main applications in quantum theory. In particular, lack of contextuality is equivalent to the existence of a “hidden” random entity of which all the random variables in play are functions. Consequently, for any given value of this common random entity, the processing times and their compositions (minima, maxima, or sums) become deterministic quantities. These quantities, in turn, can be treated as random variables with (shifted) Heaviside distribution functions, for which one can easily compute various linear combinations across different treatments, including interaction contrasts. This mathematical fact leads to a simple method, more general than the previously used ones, to investigate and characterize the interaction contrast for different types of series-parallel architectures.

We previously reported that in the Multiple Object Tracking (MOT) task, which requires tracking several identical targets moving unpredictably among identical nontargets, the nontargets appear to be inhibited, as measured by a probe-dot detection method. The inhibition appears to be local to nontargets and does not extend to the space between objects – dropping off very rapidly away from targets and nontargets. In the present three experiments we show that (1) nontargets that are identical to targets but remain (...) in a fixed location are not inhibited and (2) moving objects that have a different shape from targets are inhibited as much as same-shape nontargets, and (3) nontargets that are on a different depth plane and so are easily filtered out are not inhibited. This is consistent with a taskdependent view of item inhibition wherein nontargets are inhibited if (and only if) they are likely to be mistaken for targets. (shrink)

In this paper we attempt to identify which peer collaboration characteristics may be accountable for conceptual change through interaction. We focus on different socio‐cognitive aspects of the peer dialog and relate these with learning gains on the dyadic as well as the individual level. The scientific topic that was used for this study concerns natural selection, a topic for which students’ intuitive conceptions have been shown to be particularly robust. Learning tasks were designed according to the socio‐cognitive conflict instructional paradigm. (...) After receiving a short instructional intervention on natural selection, paired students were asked to collaboratively construct explanations for certain evolutionary phenomena while engaging in dialectical argumentation. Two quantitative coding schemes were developed, each with a different granularity. The first assessed discrete dialog moves that pertained to dialectical argumentation and to consensual explanation development. The second scheme characterized the dialog as a whole on a number of socio‐cognitive dimensions. Results from analyses on the dyadic as well as the individual level revealed that the engagement in dialectical argumentation predicted conceptual learning gains, whereas consensual explanation development did not. These findings open up new venues for research on the mechanisms of learning in and from peer collaboration. (shrink)

BackgroundSocial cognitive impairments adversely affect social functioning in patients with schizophrenia. Although pharmacological interventions have been suggested to provide some benefits on social cognition, little information is available on the comparative efficacy of pharmacotherapy. Thus, the aim of this planned systematic review and network meta-analysis is to perform a quantitative comparison of the effects of various psychotropic drugs, including supplements, on social cognition disturbances of schizophrenia.MethodsThe literature search will be carried out using the PubMed, Embase, Cochrane Central Register of Controlled (...) Trials, PsycINFO, ClinicalTrials.gov, and International Clinical Trials Registry Platform databases from inception onward. Randomized controlled trials that examined the efficacy of drugs in social cognitive disturbances will be included, based on the most recent studies and the broader literature than previously searched. This protocol defines a priori the methods that will be used for study selection, data collection, quality assessment, and statistical syntheses.DiscussionThe findings this work are expected to help promote the development of better therapeutics of social cognitive impairments in schizophrenia and related psychiatric conditions.Systematic Review Registration[www.crd.york.ac.uk/prospero], identifier [CRD42021293224].

BackgroundOver the past two decades, Uganda has experienced a significant increase in clinical research driven by both academia and industry. This has been combined with a broader spectrum of research proposals, with respect to methodologies and types of intervention that need evaluation by Research Ethics Committees (RECs) with associated increased requirement for expertise. We assessed the competencies of REC members regarding review of research protocols with complex and emerging research study designs. The aim was to guide development of a training (...) curriculum to improve the quality of scientific and ethical review.MethodsThis was a cross-sectional study design, with quantitative data collection methods. Research Ethics Committee members completed a structured pre-coded questionnaire on current competence with complex and emerging study design. REC members were asked to outline a list of additional topics for which they needed training. Data from coded questions were entered into Epidata Version 3.1 and then exported to STATA Version14.1 for analysis. Descriptive analysis was performed and findings are presented using percentages and frequencies.ResultsWe enrolled 55 REC members from 6 RECs who have a total of 97 members. The majority of whom were males (56.4%, n = 31/55). The level of competence for review of selected study design was lowest for Controlled Human Infection Model (10.9%, n = 6) and reverse pharmacology design (10.9%, n = 6), and highest for cluster randomized study design (52.7%, n = 29) and implementation science research (52.7%, n = 29).ConclusionCompetence for review of research protocols with complex and emerging study design was low among participating REC members. We recommend prioritising training of REC members on complex and emerging study designs to enhance quality of research protocol review. (shrink)

An application of the Method of Analysis of Relational Complexity (MARC) to suppositional reasoning in the knight-knave task is outlined. The task requires testing suppositions derived from statements made by individuals who either always tell the truth or always lie. Relational complexity (RC) is defined as the number of unique entities that need to be processed in parallel to arrive at a solution. A selection of five ternary and five quaternary items were presented to 53 psychology students (...) using a pencil and paper format. A computer-administered version was presented to 50 students. As predicted, quaternary problems were associated with higher error rates and longer response times than ternary problems. The computer-administered form was more difficult than the pencil and paper version of the test. These differences are discussed in terms of RC theory and alternative processing accounts. Together, they indicate that the relational complexity metric is a useful and parsimonious way to quantify complexity of reasoning tasks. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Wilhelm Dilthey, Selected Works, Volume IV: Hermeneutics and the Study of History ed. by Rudolf A. Makkreel, Frithjof RodiCharles BambachRudolf A. Makkreel and Frithjof Rodi, editors. Wilhelm Dilthey, Selected Works, Volume IV: Hermeneutics and the Study of History. Princeton: Princeton University Press, 1996. Pp. xii + 409. Cloth, $59.50.Contemporary hermeneutics has been dominated by the work of Heidegger and Gadamer. Their phenomenological approach to the human world has (...) exerted such a powerful influence in recent years that one can hardly enter a discussion about the philosophical meaning of hermeneutics that is not already framed in the terms of their discourse. At the same time, there is less familiarity with the origins and sources of the hermeneutic method or with the thought of Wilhelm Dilthey. The editors of Dilthey’s Selected Works, Rudolf Makkreel and Frithjof Rodi, have set about trying to rectify this situation. They have sought to provide a richer context for the study of hermeneutics by bringing out a six-volume collection of writings from one of the major hermeneutical philosophers in the Western tradition. The publication of Volume Four in this series helps to accomplish this task by offering new translations of important Dilthey texts covering both the history and genesis of hermeneutics and a genealogical account of Dilthey’s own hermeneutical approach to history. Only one short essay in this volume, “The Rise of Hermeneutics” (1900), has been published before, and even this older translation has been revised and supplemented by material from the Nachlass. But what is the significance of this material and how does it help to achieve a fuller understanding of hermeneutics and its history?The selections in Volume Four cover the period from 1860 to 1903 with a heavy emphasis on the period from 1860 to 1868 (over two-thirds of the book focuses on Dilthey’s 1860 Preisschrift on “Schleiermacher’s Hermeneutical System in Relation to Earlier Protestant Hermeneutics,” notes from his 1867–68 lectures “On Understanding and Hermeneutics,” and three reviews from 1862 on historical literature from Buckle, Burckhardt, and F.C. Schlosser). The remaining essays from 1900–1903 provide a sense of Dilthey’s later reflections on hermeneutics and on the meaning of the eighteenth century for historiography and as a philosophical approach to history. The editors of this collection have chosen these texts carefully; the selections in Volume Four are organized around a specific theme. By culling significant early texts about hermeneutics and history and juxtaposing them with a number of later texts on the same topics, they hope to show the genesis of Dilthey’s own path of thought. What emerges from an attentive reading of these sources—especially when carried out within the context of the editors’ own principle of selection—is a highly persuasive view of Dilthey and his work. In the texts themselves we see Dilthey moving from his earlier role as the chronicler and historian of Protestant thought (who conceives of hermeneutics as an ancillary method of textual exegesis) to his later position as the philosopher of the historical world (who views hermeneutics as the epistemological method for the grounding of the human sciences). What we see here is a developmental account of Dilthey’s thought path: from the traditional scholar who conceives of hermeneutics as a method for interpreting texts to the philosopher who understands it as the fundamental science for interpreting historical life. This shift within Dilthey’s work from a hermeneutics of textuality to a hermeneutics of historicity marks an important turning point in the history of the hermeneutical [End Page 641] tradition, a turning point that helped to form the basis of all later philosophical hermeneutics.The five essays from Part Two—“Interpretations of History”—offer a smattering of Dilthey’s own writings on historiography, the theory of history, and the role of the eighteenth-century German tradition in forging an historicist understanding of “human affairs” (373) whose “organic nexus” and “inner purposiveness as a whole” opened up a radically new conception of historical being. Most contemporary continental philosophers will get lost in the textured details of Dilthey’s analyses because what passes for “philosophy” in our epoch pales by comparison with the rich... (shrink)

Background: The new human coronavirus that leads to COVID-19 has spread rapidly around the world and has a high degree of lethality. In more severe cases, patients remain hospitalized for several days under treatment of the health team. Thus, it is important to develop and use technologies with the aim to strengthen conventional therapy by encouraging movement, physical activity, and improving cardiorespiratory fitness for patients. In this sense, therapies for exposure to virtual reality are promising and have been shown to (...) be an adequate and equivalent alternative to conventional exercise programs.Aim: This is a study protocol with the aim of comparing the conventional physical therapy intervention with the use of a non-immersive VR software during COVID-19 hospitalization.Methods: Fifty patients hospitalized with confirmed diagnosis of COVID-19 will be divided in two groups under physiotherapy treatment using conventional or VR intervention: Group A: participants with COVID-19 will start the first day of the protocol with VR tasks in the morning and then in the second period, in the afternoon, will perform the conventional exercises and Group B: participants with COVID-19 will start the first day with conventional exercises in the morning and in the second period, in the afternoon, will perform activity with VR. All participants will be evaluated with different motor and physiologic scales before and after the treatment to measure improvements.Conclusion: Considering the importance of benefits from physical activity during hospitalization, VR software shows promise as a potential mechanism for improving physical activity. The results of this study may provide new insights into hospital rehabilitation.Trial Registration:ClinicalTrials.gov, identifier: NCT04537858. Registered on 01 September 2020. (shrink)

Annotation Since clinical psychologists often have little background in cognitive psychology, and cognitive psychologists often have little training in conducting research with special populations, this book discusses the popularly used cognitive tasks in applied research, including the Stroop, Selective Attention, Implicit Memory, Directed Forgetting, and Autobiographical Memory tasks. For each, the contributors provide the background necessary for readers to ground themselves in the basics and be directed to more detailed information that they might need. The result is a text that (...) will assist researchers from different backgrounds in finding important task-related data. An up-to-date resource on conducting rigorous research. (shrink)

Designing a mechanism that provides a direct incentive for an individual to report her utility function over several alternatives is a difficult task. A framework for such mechanism design is the following: an individual (a decision maker) is faced with an optimization problem (e.g., maximization of expected utility), and a mechanism designer observes the decision maker’s action. The mechanism does reveal the individual’s utility truthfully if the mechanism designer, having observed the decision maker’s action, infers the decision maker’s utilities (...) over several alternatives. This paper studies an example of such a mechanism and discusses its application to the problem of optimal social choice. Under certain simplifying assumptions about individuals’ utility functions and about how voters choose their voting strategies, this mechanism selects the alternative that maximizes Harsanyi’s social utility function and is Pareto-efficient.

Internet-enabled technologies have provided a way for people to communicate and collaborate with each other. The collaboration and communication made crowdsourcing an efficient and effective activity. Crowdsourcing is a modern paradigm that employs cheap labors for accomplishing different types of tasks. The task is usually posted online as an open call, and members of the crowd self-select a task to be carried out. Crowdsourcing involves initiators or crowdsourcers, the crowd, crowdsourcing task, the process, and the crowdsourcing platform (...) where requesters offer various tasks and crowd workers complete these tasks. As the crowdsourcing is carried out in the online environment, it gives rise to certain challenges. The major problem is the selection of crowd that is becoming a challenging issue with the growth in crowdsourcing popularity. Crowd selection has been significantly investigated in crowdsourcing processes. Nonetheless, it has observed that the selection is based only on a single feature of the crowd worker which was not sufficient for appropriate crowd selection. For addressing the problem of crowd selection, a novel “ant colony optimization-based crowd selection method” is presented in this paper that selects a crowd worker based on multicriteria features. By utilizing the proposed model, the efficiency and effectiveness of crowdsourcing activity will be increased. (shrink)

Objective: Stand-to-sit task is an important daily function, but there is a lack of research evidence on whether knee osteoarthritis affects the postural balance during the task. This study aimed to compare individuals with knee OA and asymptomatic controls in postural balance and identify kinematic and lower extremity muscle activity characteristics in individuals with knee OA during the stand-to-sit task.Methods: In total, 30 individuals with knee OA and 30 age-matched asymptomatic controls performed the 30-s Chair Stand Test (...) at self-selected speeds. Motion analysis data and surface electromyography were collected while participants performed the 30sCST. To quantify postural balance, the displacement of the center of mass and the peak instantaneous velocity of the CoM were calculated. The kinematic data included forward lean angles of the trunk and pelvic, range of motion of the hip, knee, and ankle joints in the sagittal plane. The averaged activation levels of gluteus maximus, vastus lateralis, vastus medialis, rectus femoris, biceps femoris, tibialis anterior, and medial head of gastrocnemius muscles were indicated by the normalized root mean square amplitudes.Results: Compared with the asymptomatic control group, the knee OA group prolonged the duration of the stand-to-sit task, demonstrated significantly larger CoM displacement and peak instantaneous CoM velocity in the anterior-posterior direction, reduced ankle dorsiflexion RoM, greater anterior pelvic tilt RoM, and lower quadriceps femoris and muscles activation level coupled with higher BF muscle activation level during the stand-to-sit task.Conclusion: This study indicates that individuals with knee OA adopt greater pelvic forward lean RoM and higher BF muscle activation level during the stand-to-sit task. However, these individuals exist greater CoM excursion in the anterior-posterior direction and take more time to complete the task. This daily functional activity should be added to the rehabilitation goals for individuals with knee OA. The knee OA group performs reduced ankle dorsiflexion RoM, quadriceps femoris, and TA activation deficit. In the future, the rehabilitation programs targeting these impairments could be beneficial for restoring the functional transfer in individuals with knee OA. (shrink)

This paper reports a study of planning processes in the five-disc Tower of London (TOL) task in 20 younger and 20 older adult participants. A concurrent direct ''think-aloud'' method was used to obtain data on planning processes prior to moving discs in the TOL. A check was made of the effects of verbalising by comparing performance data from the experimental groups with data from control groups who did not verbalise during planning or moving. Verbalising slowed down planning and (...) moving but did not appear to distort the participants' approaches to the task. Older and younger participants did not differ in average moves taken to solve the tasks. However, older participants' planning was less complete and more error-prone than that of younger participants. The planning processes were characterised as showing a means-ends ''goal selection'' strategy. In this strategy participants (1) identify a single active goal disc at the start, (2) select moves and move sequences to enable the placing of the current goal disc in its target position, and (3) continue in this way until all discs are in their target positions. Age differences were found in the planning stage, during which there was no stimulus support and hence a substantial working memory load. During the move phase there was stimulus support and hence little loading of working memory. Age differences in moves required were not found in the move phase. As older participants tend to have depleted working memory capacity the present results suggest that working memory is heavily loaded in TOL planning but less so in the move phase of TOL. (shrink)

Thinking aloud is the concurrent verbalization of thoughts while performing a task. The study of thinking-aloud protocols has a long tradition in cognitive psychology, the field of education, and the industrial-organizational context. It has been used rarely in cultural and cross-cultural psychology. This paper will describe thinking aloud as a useful method in cultural and cross-cultural psychology referring to a few studies in general and one study in particular to show the wide applications of this method. Thinking-aloud (...) protocols can be applied for a) improving the validity of cross-cultural surveys, b) process analysis of thoughts and the analysis of changes over time, c) theory development across cultures, d) the study of cultural meaning systems, and e) individual as well as group level analyses allowing hypothesis testing cross-culturally. Limitations of the thinking-aloud method are also discussed. (shrink)

This research suggests a comparison between two tasks to evaluate oral communication strategies (CSs) through storytelling and interview and to compare the use of CSs between high and low proficient students. The results of the storytelling and oral interview are compared to check if CSs vary with the task and what tasks are better for each of the selected CSs. A number of 60 Spanish learners of English participated in this investigation, and a total of 232 protocols were analysed (...) to obtain the results. The main results are that CSs vary to adapt to task demands and that the frequency and type of CSs used by the students are affected by the level of proficiency of the students. This highlights the importance of selecting the appropriate task for the evaluation to be significant and the necessity to adapt the syllabus to include elements that introduce some productive CSs.

This paper reports a study of the roles of visuo-spatial and verbal working memory capacities in solving a planning task - the five-disc Tower of London (TOL) task. An individual differences approach was taken. Sixty adult participants were tested on 20 TOL tasks of varying difficulty. Total moves over the 20 TOL tasks was taken as a measure of performance. Participants were also assessed on measures of fluid intelligence (Raven's matrices), verbal short-term storage (Digit span), verbal working memory (...) span (Silly Sentence span), visuo-spatial short-term storage (Visual Pattern span and Corsi Block span), visuo-spatial working memory (Corsi Distance Estimation), visuo-spatial processing speed (Manikin test), and verbal speed (Rehearsal speed). Exploratory factor analysis using an oblique rotation method revealed three factors which were interpreted as (1) a visuo-spatial working memory factor, (2) an age-speed factor, and (3) a verbal working memory factor. The visuo-spatial and verbal factors were only moderately correlated. Performance on the TOL task loaded on the visuo-spatial factor but did not load on the other factors. It is concluded that the predominant goal-selection strategy adopted in solving the TOL relies on visuo-spatial working memory capacity and particularly involves the active ''inner scribe'' spatial rehearsal mechanism. These correlational analyses confirm and extend results previously obtained by use of dual task methods, (Phillips, Wynn, Gilhooly, Della Sala, & Logie, 1999). (shrink)

According to major cognitive theories of emotional disorders cognitive biases are partly responsible for their onset and maintenance. The direct test of this assumption is possible only if experimental method capable of altering a given form of cognitive bias is available. The purpose of the study was to examine the effectiveness of a novel implicit memory bias training procedure based on the emotional version of the classical Sternberg’s short-term memory task with negative, neutral and positive words. 108 participants, (...) who completed the PANAS and the CES-D questionnaires, were randomly assigned to the control group, the No-Negative group, in which the target words in the Sternberg’s task were either positive or neutral but never negative or the Negative-New group in which the negative target words in the modified Sternberg’s task were always new. This training was followed by the recollection stage. Only one of the training protocols resulted in significant effects at the recall stage - individuals in the No-Negative group recalled more positive words and fewer negative words than those in the control group. These results show that it may be possible to experimentally induce memory bias characteristic of non-depressed individuals. (shrink)

I perceive the most important features of the plan to be:• The legislation will create a "right" to health care for all citizens—access to care will be universal;• The plan will involve some form of managed competition in which groups of providers (called Approved or Accredited Health Plans (AHPs)) will offer comparable benefit packages at slightly (or widely) different costs;• The AHPs will negotiate with the Health Alliance (HA) to determine the price that they will charge their consumer-patients;• There will be open enrollment with no barriers to coverage, such as exclusions for pre-existing conditions;• Community rating will be in effect in different localities and enrolled persons in any AHP will pay the same premium;• The coverage for any enrolled person will be portable;• The overall structure will be a cooperative federal/state enterprise in which the states will have quite extensive abilities to fashion variations of the basic plan to meet their particular needs;• Primary care will be encouraged and incentives for physicians to train in primary care specialties provided;• Non-physician providers will be central to the functioning of the health care plans;• Efforts will be made to develop a "person power" pool so that people with an abstract "right" to health care will have real access to providers, in their localities, who can fulfill the promise that the right creates; [End Page 421]• The goal of cost containment will be central to the organization and regulation of the system;• Administrative simplicity and quality protections will be central.Co-chairing the Bioethics Working Group (BWG) of the White House Task Force on Health Care Reform was a unique experience. Approximately 40 Task Force working groups were established by Hillary Rodham Clinton, the President, and the senior Task Force staff. Various members of the President's office and other knowledgeable members of the Executive Branch selected the participants. In our group, appointments were made largely on the recommendations of the co-chairs. The BWG, among the last of the groups formed, carried the official name "The Working Group on the Ethical Foundations of the New System" and was jointly led by me and Marion Gray Secundy, a Professor of Bioethics at Howard University. The fact that the leadership of the Task Force saw fit to establish such a group, thereby confirming that bioethics is a player in the arena of health care policy, was in itself significant and was made no less so by the lack of clarity regarding the group's aims and goals.The working groups of the Task Force were organized into clusters, determined by the relatedness of the somewhat distinct, but always overlapping, content of their investigations. Separate clusters and working groups, for example, looked at mental health, long term care, and the benefit package and coverage for low-income and non-working families. On this last issue there was also a working group that explored health policy initiatives for underserved populations. This multiple focus on related issues proved to be an excellent method for ensuring that the complexity of these topics was sufficiently explored. There was a published schedule for when these groups met together, and members of other groups who had similar or overlapping concerns were invited to attend and to participate.Every week or so, all of the working groups reported to the Task Force leadership, under the direction of Ira Magaziner, in a process called a "tollgate." Prior to the tollgate, the working groups were required to submit formal written analyses of the problems they had most recently been considering. Copies of these documents were placed in a special room so that those who were interested could review... (shrink)
