This paper presents a series of meta-analyses of the validity of general mental ability (GMA) for predicting five occupational criteria, including supervisory ratings of job performance, production records, work sample tests, instructor ratings, and grades. The meta-analyses were conducted with a large database of 467 technical reports of the validity of the General Aptitude Test Battery (GATB) which included 630 independent samples. GMA showed to be a consistent predictor of the five criteria, but the (...) magnitude of the operational validity was not the same across the five criteria. Results also showed that job complexity is a moderator of the GMA validity for the performance criteria. We also found that the GMA validity estimates are slightly smaller than the previous ones obtained by Hunter (1983a; Hunter & Hunter, 1984). Finally, we discuss the implications of these findings for the research and practice of personnel selection. (shrink)

Over the last decades, various predictors have proven relevant for job performance [e.g., general mental ability, broad personality traits, such as the Big Five]. However, prediction of job performance is far from perfect, and further potentially relevant predictors need to be investigated. Narrower personality traits, such as individuals' character strengths, have emerged as meaningfully related to different aspects of job performance. However, it is still unclear whether character strengths can explain additional variance in job performance over and (...) above already known powerful predictors. Consequently, the present study aimed at examining the incremental validity of character strengths as predictors of job performance beyond GMA and/or the Big Five traits and identifying the most important predictors of job performance out of the 24 character strengths, GMA, and the Big Five. Job performance was operationalized with multidimensional measures of both productive and counterproductive work behavior. A sample of 169 employees from different occupations completed web-based self-assessments on character strengths, GMA, and the Big Five. Additionally, the employees' supervisors provided web-based ratings of their job performance. Results showed that character strengths incrementally predicted job performance beyond GMA, the Big Five, or GMA plus the Big Five; explained variance increased up to 54.8, 43.1, and 38.4%, respectively, depending on the dimension of job performance. Exploratory relative weight analyses revealed that for each of the dimensions of job performance, at least one character strength explained a numerically higher amount of variance than GMA and the Big Five, except for individual task proactivity, where GMA exhibited the numerically highest amount of explained variance. The present study shows that character strengths are relevant predictors of job performance in addition to GMA and other conceptualizations of personality. This also highlights the role of socio-emotional skills, such as character strengths, for the understanding of performance outcomes above and beyond cognitive ability. (shrink)

The Mental Health Literacy Scale is the most widely used and strong theory-based measurement tool to gain an understanding of mental health knowledge and ability. This study aimed to test the psychometric properties of the Chinese version of the Mental Health Literacy Scale and to document the norm and its influential factors of mental health literacy among nurses. The MHLS was translated following Brislin’s translation model and tested with a sample of 872 clinical registered nurses. (...) The Jefferson Scale of Empathy-Health Professionals, Patient Health Questionnaire-2, and Generalized Anxiety Disorder-2 were administered to assess convergent validity. The minimum average partial test, parallel analysis and confirmatory factor analysis supported 4 first-order 2 second-order structure. The 4 factors were named “knowledge of mental disorder,” “ability to seek information and help,” “recognition of mental disorder,” and “acceptance of patients with mental illness,” with factor 1-3 were summarized into MHLS-Core and factor 4 as MHLS-SA. The MHLS-C was moderately negatively correlated with the PHQ-2 and GAD-2 and highly positively correlated with JSE-HP. The Cronbach’s α was 0.85 for the overall scale and 0.89 and 0.93 for two subscales. The test-retest reliability was good, with intraclass correlation coefficients of 0.80 for the whole scale, and 0.79 and 0.94 for two subscales. As an approximately normal distribution, the 50th percentile for the MHLS-C was 99, with 50th percentiles of 74 and 20 for MHLS-Core and MHLS-SA. Higher position, higher professional credentials, higher hospital hierarchy, other specialist hospital, psychiatric hospital and unmarried status were positive predictors. The 29-item MHLS-C, with two subscales of MHLS-Core and MHLE-SA, is a stable and validated tool to measure mental health literacy. MHLS-Core could be used independently to measure the core content of mental health literacy. It may be applicable for Chinese health professionals, but need further validation among the general public. MHL curriculum and a targeted culturally appropriate program for acceptance for health professionals, especially for those in general hospitals and with less working tenure, may be recommended.

Rapid individual cognitive phenotyping holds the potential to revolutionize domains as wide‐ranging as personalized learning, employment practices, and precision psychiatry. Going beyond limitations imposed by traditional lab‐based experiments, new efforts have been underway toward greater ecological validity and participant diversity to capture the full range of individual differences in cognitive abilities and behaviors across the general population. Building on this, we developed Skill Lab, a novel game‐based tool that simultaneously assesses a broad suite of cognitive abilities while providing (...) an engaging narrative. Skill Lab consists of six mini‐games as well as 14 established cognitive ability tasks. Using a popular citizen science platform (N = 10,725), we conducted a comprehensive validation in the wild of a game‐based cognitive assessment suite. Based on the game and validation task data, we constructed reliable models to simultaneously predict eight cognitive abilities based on the users’ in‐game behavior. Follow‐up validation tests revealed that the models can discriminate nuances contained within each separate cognitive ability as well as capture a shared main factor of generalized cognitive ability. Our game‐based measures are five times faster to complete than the equivalent task‐based measures and replicate previous findings on the decline of certain cognitive abilities with age in our large cross‐sectional population sample (N = 6369). Taken together, our results demonstrate the feasibility of rapid in‐the‐wild systematic assessment of cognitive abilities as a promising first step toward population‐scale benchmarking and individualized mental health diagnostics.

IntroductionFirst aiders are commonly exposed to different forms of traumatic event during their duties, such as Chronic Indirect Vicarious Exposure which refers to an indirect exposure to aversive details of the trauma. If the psychopathological impact of TE is well documented, the mental health of first aiders remains neglected. Therefore, our main objectives are to study the link between exposure to traumatic events and psychopathological outcomes and to quantify the rates of mental health disorders among first aiders.MethodOur sample (...) comprised of 53 volunteer first aiders with an average age of 32.4 years. Traumatic event exposure and mental health were assessed through a set of validated questionnaires completed online.ResultsRates of mental health outcomes were higher than within the general population. Females showed higher scores of post-traumatic stress disorder than males. PTSD scores were significantly correlated with all mental issues scores, apart from tobacco use and eating disorders scores. There was a significant correlation between the number of traumatic events and the years of experience. Exposure to traumatic events only correlated with nicotine dependency. No other correlation reaches statistical significance.DiscussionThe scores of all mental health outcomes were high; a surprising result, as volunteer first aiders are thought to be recruited for their strong dispositional cognitive and emotional abilities. The high levels of post-traumatic stress disorder and burnout, along with the prevalent anxiety and depression, highlight the need for greater psychosocial support. Resilience training and peer support would be useful interventions in this group. (shrink)

This study investigated individual differences in the belief bias effect, which is the tendency to accept conclusions because they are believable rather than because they are logically valid. It was observed that the extent of an individual's belief bias effect was unrelated to a number of measures of reasoning competence. Instead, as predicted by mental models theory, it was related to a person's ability to generate alternative representations of premises: the more alternatives a person generated, the less likely (...) they were to show a belief bias effect. In contrast to belief effects, which were predicted by the number of alternatives generated, scores on logical reasoning tasks were predicted by an individual's understanding of the concept of logical necessity. These two mediating variables, ability to generate alternatives and understanding of logical necessity, were themselves predicted by similar variables, such as cognitive motivation and abstract reasoning ability. Our findings strongly support the mental models interpretation of the belief bias effect, and suggest that individual differences in this effect are associated with a specific ability to generate alternatives, rather than with a general logical competence.

OBJECTIVE: Questions have been posed about the competence of persons with serious mental illness to consent to participate in clinical research. This study compared competence-related abilities of hospitalized persons with schizophrenia with those of a comparison sample of persons from the community who had never had a psychiatric hospitalization. METHODS: The study participants were administered the MacArthur Competence Assessment Tool for Clinical Research (MacCAT-CR), a structured instrument designed to aid in the assessment of competence to consent to clinical research. (...) The scores of 27 persons who met DSM-IV criteria for schizophrenia who were long-stay patients on a state hospital research ward were compared with those of 24 individuals from the community who were of similar age, gender, race, and socioeconomic status. RESULTS: Significant differences were found between the patients and the community sample on three measures of competence-related abilities: understanding, reasoning, and appreciation. Degree of psychopathology and cognitive functioning were significantly negatively correlated with understanding and appreciation among the patients with schizophrenia. Length of hospitalization was significantly negatively correlated with all measures of decision-making capacities. CONCLUSIONS: The generally poor performance of the long-stay patients with chronic schizophrenia highlights the difficulties this group is likely to encounter in providing consent to research. However, variation across the sample points to the need for individualized assessment and for validated techniques for facilitating decision making in the face of decisional impairments. (shrink)

This paper explores citizens’ views about the welfare of farmed fish and the mental abilities of fish with a large survey data sample from Finland (n = 1,890). Although studies on attitudes towards animal welfare have been increasing, fish welfare has received only limited empirical attention, despite the rapid expansion of aquaculture sector. The results show that the welfare of farmed fish is not any great concern in the Finnish society. The analysis confirms the distinct character given to farmed (...) fish compared to traditional farmed animals. Salmon are rated low in their mental abilities, including the capacity to feel pain, which may weaken ethical concerns for fish welfare. When analyzing the social determinants surrounding the rating of the welfare of farmed fish, it was shown that fish welfare attitudes follow general animal welfare attitudes regarding age and place of residence as fish welfare tends to be rated more negatively among younger age groups and among urban residents. However, no clear connection could be identified between gender and the rating of fish welfare, which may suggest that the distinct cultural categorization of fish diminishes the typical gender difference identified in animal attitudes. It is concluded that in order to improve awareness about fish welfare, there is a need to increase dissemination of scientific knowledge about fish and their welfare. Moreover, further research should be directed toward studying the moral positioning of fish and the distinct moral categorization they receive. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Anorexia and the MacCAT-T Test for Mental Competence:Validity, Value, and EmotionLouis C. Charland (bio)Keywordsmental competence, decisional capacity, anorexia, value, emotionValidity of the MacCAT-THow does one scientifically verify a psychometric instrument designed to assess the mental competence of medical patients who are asked to consent to medical treatment? Aside from satisfying technical requirements like statistical reliability, results yielded by such a test must conform to at least (...) some accepted pretheoretical desiderata; for example, determinations of competence, as measured by the test, must capture a minimal core of accepted basic intuitions about what competence means and what a theory of competence is supposed to do. The concepts of "face validity" and "content validity" are both important here. Face validity "indicates that an instrument appears to test what it is supposed to and that it is a plausible method for doing so" (Portney and Watkins 2000, 82). Content validity "means that the test contains all the elements that reflect the variable being studied" (Portney and Watkins 2000, 83). An adequate instrument for measuring mental competence must at minimum satisfy both of these requirements.What Tan and her colleagues (2006) have shown is that the MacArthur Competence Assessment Tool—Treatment (MacCAT-T) test for mental competence may not be an empirically valid measure of mental competence for some cases of anorexia. The data they report show that "competence," as measured by the MacCAT-T, does not conform sufficiently well with what is wanted of a clinical medical theory of competence. More specifically, the MacCAT-T is deficient in both face and content validity. This result is extremely significant; previous challenges to the validity of the MacCAT-T have often been largely theoretical in nature. My own objection that the MacCAT is inadequate because it omits the influence of emotion is based on a combination of empirical theory (Charland 1998a) and philosophical argument (Charland 1998b). However, it is entirely theoretical in nature. So is my argument that in ignoring emotion the MacCAT misses a crucial contributing ingredient in competence, namely, value (Charland 2001, see especially 136 note 2). Tan's study provides valuable empirical evidence for the second of these challenges, which deals more specifically with value. On the one hand, the study clearly demonstrates that patients sometimes do [End Page 283] base their treatment decisions on reasons derived from values. And on the other hand, it also nicely illustrates the centrality of values—"utilities" or "preferences"—in the decision-making process generally; a basic assumption of standard decision theory for which, paradoxically, there appears to be no satisfactory counterpart in the MacCAT-T model of reasoning and decision making.Thus, values figure among the reasons that patients actually use in reasoning when they weigh the risks and benefits of proposed treatment options. The MacCAT-T must be amended to incorporate this fact if it is to be a satisfactory clinical medical tool. Without such a correction, the concept of mental competence it measures is empirically invalid. At the root of the problem is a clash of intuitions. Tan's data provide convincing evidence that some of the patients who are deemed to be mentally competent by MacCAT-T standards should not in fact be considered competent. Note that the language in which this clash is expressed—"should not in fact"—involves a combination of descriptive and prescriptive elements, reminding us that the concept of competence is dual in nature: it is both prescriptive and descriptive (Freedman 1981). These problems underscore the need for greater clarity about what pretheoretically we want a clinical theory and test of competence to capture. It is of course reasonable to say that such a test must be consistent with major tenets of the relevant case law (Appelbaum 1998). But a legally valid concept of competence of this sort is too thin and arbitrary a foundation on which to build a clinical medical theory of competence. An empirically valid theory and test of the latter sort must incorporate the role of values if it is be truly helpful in medical practice.Value and the MacCAT-TI agree with Tan and her colleagues that some notion of "pathological value" needs to be...

Aim: The main aim of the present study is to identify which mental footnotes (related to Marx’s and Engels’ Socialism) have more weight in the current cognitive processing of citizens. Background: We used the “Manifesto of the communist party” as the main source of the thoughts from these authors. Method: An experimental design (based on a previous qualitative research) was carried out to test the influence of mental footnotes on the citizens’ decision on the validity of the (...) concepts. Results: The findings point out that there are strong, current, mental footnotes related to the Marx’s and Engels’ concept of bourgeoisie. Conclusions: The Marx’s and Engels’ Philosophy is currently alive, at least, some concepts related to bourgeoisie. People mostly think that the current means of production of modern bourgeoisie were developed in the feudal age, proletariat struggles with bourgeoisie from the beginning, Communism and Socialism are the only political movement that recognized this bourgeoisie-proletariat antagonism and the means of production are nowadays extended to other social classes. The present methodology (from an Experimental Psychology perspective) means a reliable technique to extract the essence of a text and to test the influence of its concepts on human cognitive processing.

Generalized anxiety disorder can cause significant socioeconomic burden and daily life dysfunction; hence, therapeutic intervention through early detection is important. This study was the final stage of a 3-year anxiety screening tool development project that evaluated the psychometric properties and diagnostic screening utility of the Mental Health Screening Tool for Anxiety Disorders, which measures GAD. A total of 527 Koreans completed online and offline versions of the MHS: A, Beck Anxiety Inventory, Generalized Anxiety Disorder-7, and Penn State Worry Questionnaire. (...) The participants had an average age of 38.6 years and included 340 females. Participants were also administered the Mini-International Neuropsychiatric Interview. Internal consistency, convergent/criterion validity, item characteristics, and test information were assessed based on the item response theory, and a factor analysis and cut-off score analyses were conducted. The MHS: A had good internal consistency and good convergent validity with other anxiety scales. The two versions of the MHS: A were nearly identical. It had a one-factor structure and showed better diagnostic accuracy for GAD detection than the GAD-7 and BAI. The IRT analysis indicated that the MHS: A was most informative as a screening tool for GAD. The MHS: A can serve as a clinically useful screening tool for GAD in Korea. Furthermore, it can be administered both online and offline and can be flexibly used as a brief mental health screener, especially with the current rise in telehealth. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Philosophy, Psychiatry, & Psychology 13.2 (2006) 133-141MuseSearchJournalsThis JournalContents[Access article in PDF]Dysfunctions, Disabilities, and Disordered MindsBengt BrüldeFilip RadovicRichard Gipps' and Jerome Wakefield's commentaries on our article are so different from each other that we have decided to deal with them separately. Gipps suggests that we adopt a different framework altogether. In his view, our main question—"What makes a mental disorder mental?"—is somehow defective, and it ought to be (...) replaced by an alternative question, namely, "What makes a mind disordered?" He thinks he can answer this question by providing an alternative account of the mental in terms of intentionality and suigeneris psychological understanding. He also suggests that mental disorders are "alterations within the intentional order." Wakefield, on the other hand, shares most of our "framework assumptions"; for example, he accepts the way we formulate our central question and how we present the different possible answers. The only part of our general project to which he objects is the attempt to find a principled account of what makes a mental function (dysfunction, mechanism, ability, or the like) mental. His main purpose is to defend and develop his own version of the internal cause view, namely, the idea that mental disorders are (harmful) mental dysfunctions. Because Gipps' comments are of a far more general nature than Wakefield's, we respond to Gipps first. This gives us an opportunity to make our "framework assumptions" more explicit.Gipps' Criticism of the Notion of Mental DisorderLet us first note that Gipps' suggestions are often vague. As Gipps himself puts it, his account is "clearly in need of much further clarification and elaboration" (121). This means that we sometimes have to reconstruct what he says to attribute sufficiently clear views to him.Gipps questions our assumption that there is such a thing as a general category of disorder, of which mental and somatic disorders can be regarded as subcategories. Or more precisely, he rejects the view that "disorder" is a proper category (or "semantic category," as he puts it), and he also seems to deny that "mental disorder" is a category. This is supposed to imply that our central question is somehow wrongly formulated, and to pave the way for his reformulation of this question (from now on, "the move").To determine whether Gipps' objection is valid or not, we need to know what he means by the term "category." However, all we are told is that a noun designates a (semantic) category if and only if it has a "unitary sense." Unfortunately, he does not specify what this "unitary sense" consists in. For example, does he implicitly assume that a noun designates a category if and only if there are necessary conditions for membership that are jointly sufficient? The example he offers (see [End Page 133] p. 118) suggests another possible interpretation, however. Here, he claims that the relation between the terms "mental disorder" and "physical disorder" are analogous to the relation between the terms "chemical reaction" and "emotional reaction." This suggests that the term "disorder" as it occurs in the phrase "physical disorder" and the term "disorder" as it occurs in the phrase "mental disorder" have different senses. This is an interesting suggestion that may well be correct, but Gipps does not offer any arguments for the assumption that "disorder" behaves like "reaction." Neither does he offer any examples of proper (semantic) categories.The Move from "Mental Disorders" to "Disordered Minds"In Gipps' view, mental disorders are best conceived of as disorders of the mind, and physical disorders as disorders of the body, and he therefore suggests that we ask what makes a disordered mind disordered rather than what makes a mental disorder mental. But why does Gipps believe that this move from "mental disorder" to "disordered minds" constitutes an improvement? The first reason has already been given, namely that the term "disorder" might not designate a proper category. But this is not a good reason for making the move Gipps suggests unless we assume that "mind" and "body" are proper categories. At this... (shrink)

Generales, Amelita L. de Guzman The primary purpose of this study is to ascertain the benefits of the National Service Training Program implementation and to identify the problems encountered by its implementers. Results showed that the benefits derived from the program were topped by enhancement of skills on basic leadership with emphases on the ability to listen and ability to communicate which were rated very important and very much benefited among (...) other training aspects of the program. Results also revealed that students are aware of the importance of physical, mental and social health as well as the observance of proper hygiene for overall sense of well-being. Although recreation is one aspect that the respondents find important, appreciation of it underscores the need to have more time for assignments and projects as most of the respondents are enrolled in their respective courses with 29 units, making them unable to appreciate the perks of involving themselves into various recreational activities. Problems in the implementation showed lack of provision of materials and equipment and of budgetary allocation which rendered full implementation weak as students and faculty involved in the community immersion have to rely on their own resources, in addition to the indifference and passivity of the local government officials. Based on the findings, the researchers recommended that: the school administrators need to allocate adequate budget for materials and equipment; periodic faculty development trainings and; to look into the passive attitude of the local officials to ensure that implementation NSTP projects will benefit both clients and implementers. ]]>.

Many families worldwide have at least one member with a behavioral or mental disorder, and yet the majority of the public fails to correctly recognize symptoms of mental illness. Previous research has found that Mental Health Literacy (MHL)—the knowledge and positive beliefs about mental disorders—tends to be higher in European and North American cultures, compared to Asian and African cultures. Nonetheless quantitative research examining the variables that explain this cultural difference remains limited. The purpose of our (...) study was fourfold: (a) to validate measures of MHL cross-culturally, (b) to examine the MHL model quantitatively, (c) to investigate cultural differences in the MHL model, and (d) to examine collectivism as a predictor of MHL. We validated measures of MHL in European American and Indian samples. The results lend strong quantitative support to the MHL model. Recognition of symptoms of mental illness was a central variable: greater recognition predicted greater endorsement of social causes of mental illness and endorsement of professional help-seeking as well as lesser endorsement of lay help-seeking. The MHL model also showed an overwhelming cultural difference; namely, lay help-seeking beliefs played a central role in the Indian sample, and a negligible role in the European American sample. Further, collectivism was positively associated with causal beliefs of mental illness in the European American sample, and with lay help-seeking beliefs in the Indian sample. These findings demonstrate the importance of understanding cultural differences in beliefs about mental illness, particularly in relation to help-seeking beliefs. (shrink)

Scholars studying the origins and evolution of language are also interested in the general issue of the evolution of cognition. Language is not an isolated capability of the individual, but has intrinsic relationships with many other behavioral, cognitive, and social abilities. By understanding the mechanisms underlying the evolution of linguistic abilities, it is possible to understand the evolution of cognitive abilities. Cognitivism, one of the current approaches in psychology and cognitive science, proposes that symbol systems capture mental phenomena, (...) and attributes cognitive validity to them. Therefore, in the same way that language is considered the prototype of cognitive abilities, a symbol system has become the prototype for studying language and cognitive systems. Symbol systems are advantageous as they are easily studied through computer simulation (a computer program is a symbol system itself), and this is why language is often studied using computational models.

Psychiatric research is in crisis because of repeated failures to discover new drugs for mental disorders. Lack of measurement validity could partly account for these failures. If researchers do not actually measure the effects of drugs on the disorders they aim to investigate, one should expect suboptimal treatment outcomes. I argue that this is the case, focusing on depression, and fear & anxiety disorders. In doing so, I show how psychiatric research illustrates a more general phenomenon that (...) I call “validity drift.” A validity drift occurs when, in the course of developing new measurement procedures, researchers end up studying something different from what they originally aimed to study. I analyze the different ways in which scientists attempt to validate procedures for measuring mental disorders for the purpose of testing drugs in animal models. I show how those validation efforts might fail, thereby leading to validity drifts. Overall, this analysis highlights the complex interplay between the development of new measurement procedures, their calibration, and scientific theories of the target phenomena. (shrink)

Hauser argues that his pocket calculator (Cal) has certain arithmetical abilities: it seems Cal calculates. That calculating is thinking seems equally untendentious. Yet these two claims together provide premises for a seemingly valid syllogism whose conclusion - Cal thinks - most would deny. He considers several ways to avoid this conclusion, and finds them mostly wanting. Either we ourselves can't be said to think or calculate if our calculation-like performances are judged by the standards proposed to rule out Cal; or (...) the standards- e.g., autonomy and self-consciousness- make it impossible to verify whether anything or anyone (save oneself) meets them. While appeals to the intentionality of thought or the unity of minds provide more credible lines of resistance, available accounts of intentionality and mental unity are insufficiently clear and warranted to provide very substantial arguments against Cal's title to be called a thinking thing. Indeed, considerations favoring granting that title are more formidable than is generally appreciated. Rapaport's comments suggest that, on a strong view of thinking, mere calculating is not thinking (and pocket calculators don't think), but on a weak, but unexciting, sense of thinking, pocket calculators do think. He closes with some observations on the implications of this conclusion. (shrink)

New emerging biotechnologies, such as gene editing, vastly extend our ability to alter the human being. This comes together with strong aspirations to improve humans not only physically, but also mentally, morally, and socially. These conjoined ambitions aggregate to what can be labelled “the gene editing of super-ego.” This article investigates a general way used to argue for new biotechnologies, such as gene-editing: if it is safe and efficacious to implement technology X for the purpose of a common (...) good Y, why should we not do so? This is a rhetorical question with a conditional, and may be dismissed as such. Moreover, investigating the question transformed into a formal argument reveals that the argument does not hold either. Nonetheless, the compelling force of the question calls for closer scrutiny, revealing that this way of arguing for biotechnology is based on five assumptions. Analysis of these assumptions shows their significant axiological, empirical, and philosophical challenges. This makes it reasonable to claim that these kinds of question based promotions of specific biotechnologies fail. Hence, the aspirations to make a super-man with a super-ego appear fundamentally flawed. As these types of moral bioenhancement arguments become more prevalent, a revealing hype test is suggested: What is special with this technology, compared to existing methods, that makes it successful in improving human social characteristics in order to make the world a better place for all? Valid answers to this question will provide good reasons to pursue such technologies. Hence, the aim is not to bar the development of modern biotechnology, but rather to ensure good developments and applications of highly potent technologies. So far, we still have a long way to go to make persons with goodness gene. (shrink)

This study examined individual differences in spatial abilities of architecture students. Students at different educational levels were assessed on spatial ability tests that varied in their domain-specificity to architecture, with the hypothesis that larger differences between beginner and advanced students will emerge on more domain-specific tests. We also investigated gender differences in test performance and controlled for general reasoning ability across analyses. In a cross sectional study, master students (N= 91) outperformed beginners (N= 502) on two novel (...) tests involving perspective taking and object composition, as well as on a standardized visualization of cross-sections test, but not on a standardized mental rotations test. Longitudinally (N= 117), spatial performance improved after the first bachelor year on visualization of cross-sections, object composition and mental rotation. Although both genders showed higher spatial test performance with increased experience, male students outperformed females across tests and levels of education. The results overall confirmed improvements in spatial performance during architecture studies, with partial support for the domain-specificity hypothesis. A gender gap among advanced students calls for further examining architecture-specific spatial thinking. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Appreciating Anorexia:Decisional Capacity and the Role of ValuesThomas Grisso (bio) and Paul S. Appelbaum (bio)Keywordscompetence, consent, anorexia, appreciation, decision makingTan and her colleagues (2006) reported that persons with anorexia nervosa typically manifest no difficulty satisfying the criteria for abilities associated with competence to consent to or refuse treatment. Their results led them to conclude that these patients generally had no problem grasping the nature of anorexia and its possible (...) consequences (understanding), typically did not have difficulty processing information when making treatment decisions (reasoning), and usually neither denied that they had a disorder nor manifested distorted beliefs about the potential consequences of treatment for the disorder.Nevertheless, these authors found, some anorexia patients said that they knew they might die and that they would rather die than suffer the alternative consequences (e.g., loss of identity, feeling of being disgusting). They point out that these beliefs, suggesting questionable competence, were not identified by the usual criteria for competence to consent to treatment. Therefore, they propose that we should consider a modification of the criteria for competence to consent to treatment. They argue for inclusion of "pathological values" as the basis for a finding of incompetence. Their notion of a pathological value (as we summarize it based on their Discussion) includes (a) a personal value (b) on which treatment refusal is based, that (c) is not authentic, and (d) is due to a mental disorder.Second, Tan and colleagues were concerned that the MacArthur Competence Assessment Tool for Treatment (MacCAT-T), currently used widely to assess competence to consent to treatment, did not seem to take values into account when examining deficits related to lack of appreciation or reasoning. They point out that most patients with anorexia nervosa in their study had "pathological values" that influenced their thinking about treatment, yet they did not obtain poor scores on the instrument's appreciation scale, which assesses whether patients deny that they have the illness or offer reasons for accepting or refusing treatment that are based on delusional premises or a serious distortion of reality. Moreover, almost all of the anorexia patients in the study obtained adequate scores on reasoning, which examines the ability to process options and consequences when weighing a treatment decision. [End Page 293]Reasons for Caution in Altering Criteria for CompetenceA fundamental step in considering Tan and her co-worker's proposal is to examine whether it is necessary to add a concept of "pathological values" to the legal construct of competence to consent to treatment. Modifying the legal doctrine of consent is important if that is needed to improve its validity or reliability. But modifications of the doctrine would have considerable costs, including a long process of producing logical and empirical evidence for its necessity, developing methods to assess the new concept, and then a process of debate, persuasion, and education to change laws, ethical guidelines, and medical training. Moreover, principles of theory building urge parsimony. A theory should employ no more concepts or assumptions than are required to account for the phenomena that the theory seeks to organize or explain. So one must be sure that modifications are truly necessary before adding complexity to the theory of decisional competence.In addition, there is an inherent danger in altering a concept like competence to consent to treatment on the basis of the study of any one mental disorder. It is not at all clear how the modification might influence findings of competence when applied to other disorders. Using a study of patients with anorexia nervosa as the impetus for changing the competence concept runs this risk. For example, anorexia is one of a class of mental disorders that is characterized by a failure to abstain from behavior (here, limiting food intake and other behaviors designed to reduce weight) that has negative consequences for the person. Other conditions in this category might include substance abuse disorders and impulse control disorders (e.g., pathological gambling). Even if one concludes that revised criteria for competence would reduce false-positive findings of competence in this group of disorders, one would have to consider carefully its impact on the full range of disabling mental conditions.Moreover, the sensitivity...

Originally identified by Hume, the validity of is–ought inference is much debated in the meta-ethics literature. Our work shows that inference from is to ought typically proceeds from contextualised, value-laden causal utility conditional, bridging into a deontic conclusion. Such conditional statements tell us what actions are needed to achieve or avoid consequences that are good or bad. Psychological research has established that people generally reason fluently and easily with utility conditionals. Our own research also has shown that people’s reasoning (...) from is to ought is pragmatically sensitive and adapted to achieving the individual’s goals. But how do we acquire the necessary deontic rules? In this paper, we provide a rationale for this facility linked to Evans’s framework of dual mind rationality. People have an old mind which derives its rationality by repeating what has worked in the past, mostly by experiential learning. New mind rationality, in contrast, is evolutionarily recent, uniquely developed in humans, and draws on our ability to mentally simulate hypothetical events removed in time and place. We contend that the new mind achieves its goals by inducing and applying deontic rules and that a mechanism of deontic introduction evolved for this purpose. (shrink)

The paper presents the construction of a new class of logics, which are called logics of derivational trees. The presentation comprises three sections: (i) intuitive psychological motivations for these logics stemming from some results of developmental psycho-linguistics (Piaget, Chomsky), (ii) the construction of formal calculus with help of algorithmic tools, and (iii) the construction of set-theoretic semantic model for our logic. They determine criteria of valid deriving and transforming structures which are usually described in the literature as derivational trees. These (...) structures are used in linguistics or in computational sciences as tools of modelling deep sentential structures or information-bases. Furthermore cognitive anthropologists notice that most of our ordinary taxonomies arranging the experienced world in our Lebenswelt possess various tree-structures. It seems that our abilities of applying tree-structures (without explicit knowledge concerned with algebraic mechanisms of construing tree-structures) in various segments of our life are mental and behavioral manifestation of some special logical disposal belonging to the machinery of logical competence in general. It is interesting to put the hypothesis according to which the competence of construing and applying tree-structures is even more primitive than the competence of applying logical rules of natural deduction. The presented calculus possesses some peculiar feature, namely its formal language is composed of expressions of three syntactic levels. In standard, formal languages all expressions may be divided as belonging to two levels: the level of formulas and the level of constituents of formulas. In the language of derivational trees there are distinguished the following levels: (i) the level of lexical expressions, (ii) the level of derivation-expressions, (iii) and finally the level of transformation-expressions. These last category fulfils the role of formulas. Proofs are appropriate sequences of derivation-expressions. However what is proved is not a derivation-expression but it is a transformation-expression. The peculiarity of our logic consists in that an expression which is proved, does not belong to the category of constituents of proofs. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:The Ambiguities of Mild Cognitive ImpairmentTim Thornton (bio)Keywordsclassification, disease, mild cognitive impairment, normative, valuesCorner and Bond's paper (2006) raises some key ethical questions about the classification and diagnosis of mild cognitive impairment (MCI). In this commentary, I wish to revise some of the general issues about the classification of mental disorder raised by this particular classificatory concept. The central issue raised is the connection between the pathologic (...) status of a condition and what I term the plain facts about the frequency and nature of its symptoms.There are a number of ethical questions raised by applying the label of MCI. Centrally, perhaps, is the concern, illustrated by the case vignettes, that a diagnosis carries negative repercussions that might outweigh the more narrowly medical advantages of an early diagnosis. But although that concern may be appropriate, such ethical complications are a danger of any psychiatric classification or diagnosis, even the most well grounded. Any psychiatric diagnosis can carry a danger of stigma, for example.What seems to make such ethical concerns more serious in this case—at least to a philosopher outsider—is the implicit further concern that MCI is not a real, objective, or, to use a more medical term, valid category or classification. If it is not valid, then any negative connotations of the diagnosis will not be outweighed by medical technological achievements. In other words, the further ethical issues are given much greater weight if the question of validity is not satisfactorily resolved.The question of the reality, objectivity, or validity of MCI can be divided into two issues:1. Is MCI a real, objective, or valid feature of psychological phenomenology?2. Is MCI a real, objective, or valid psychological illness, disease, or pathology?A condition might be a real, objective, or valid feature of psychological phenomenology without being a real illness. It might be some other aspect of human living. Szasz (1960) suggests that this is the case with mental illness (he might more properly say "so-called mental illness") as a whole. But, less controversially, the unusual ability to calculate, mentally and in a flash, the date of future Easter Sundays is a genuine feature of human living—some people possess the ability even if most do not—without either it, or its lack, being an illness. Being real as an illness is a very specific kind of being. It is this, I suggest, that raises difficulties in the case of MCI by contrast with the easier question of whether something is a genuine feature of human living in some other way. [End Page 21]From "normal" and "normative" to "correct" and "incorrect"Corner and Bond (2006) usefully suggest that the question of whether MCI is real is made more difficult by an ambiguity in the sense of the word normal. They suggest that although "physiologic and cognitive decline is assumed to be a normal experience" this still leaves "boundary problems" about "distinguishing normal aging from disease" (Corner and Bond 2006, 3–4). Thus, if the symptoms of MCI are continuous with the ordinary phenomena of physiologic and cognitive decline, then they might also be merely normal. But this does not settle the status of MCI because normal can mean either "normative, that is, usual; or it can mean nonpathologic" (Corner and Bond 2006, 4).On the assumption that MCI is at least continuous with phenomena that are normal, then its symptoms might be normal in the sense of usual but nevertheless pathologic: an inevitable illness. Or they might be usual and nonpathologic, that is, merely a feature of aging that, although regrettable, lacks the connotations of illness (e.g., the appropriateness, if not the possibility, of treatment). (In principle on the assumption in play—that the symptoms of MCI are normal—they might be unusual but nonpathologic akin, for example, to an improved ability to solve crosswords with age that might affect a small lucky proportion of the population. Perhaps such a crossword puzzler might be reassured by their doctor: "Well that is very unusual but there is no need to worry: it is not a symptom of any illness. You are perfectly normal.")Thus the question "Is MCI normal... (shrink)

A modern version of the classical Greek organic paradigm can be based on behavioural ecology, ecology being the study of the interrelationships between an organism and its environment. The ecological organic paradigm describes four general human mental functional capacities -- appetite, social conscience, reason and an interpretive capacity -- and associates them, in the context of evolutionary and psychological development, to four general categories of experience -- primal individual needs, society, the natural world in which we live (...) and metaphysics -- with which we have to cope, adapt, and interrelate. The ecological organic paradigm is compatible with both natural and cultural evolution. The framework can accommodate both descriptive and normative concepts of human nature and it can accommodate both the individual and social dimensions of human knowledge and activity. The framework gives some coherence to the ethical categories. The questions, What is obligatory? What is good? What is fitting? and What is humane? are all included within the framework as valid moral questions. Deontological, normative, communitarian and individual human concerns are all recognized. One way to understand the ecological organic paradigm is to contrast it with the general state of philosophy in the last one hundred years, which might be compared to the story of the blind men describing an elephant: each perspective describes a particular part but none gives a coherent view of the elephant. The EOP suggests that we reconsider in the context of behavioural ecology a modern version of the organic paradigm as at least one useful framework for describing the ‘elephant'.The EOP is a framework of analysis that has the ability to bring a greater degree of coherence to discussions in moral and political philosophy and to provide a basis for accommodation in a pluralistic society and world community.

Free will, if such there be, involves free choosing: the ability to mentally choose an outcome, where the outcome is 'free' in being, in some substantive sense, up to the agent of the choice. As such, it is clear that the questions of how to understand free will and mental causation are connected, for events of seemingly free choosing are mental events that appear to be efficacious vis-a-vis other mental events as well as physical events. Nonetheless, (...) the free will and mental causation debates have proceeded largely independently of each other. Here we aim to make progress in determining how the free will and mental causation debates bear on one another. We first argue that the problems of free will and of mental causation can be seen as special cases of a more general problem, concerning whether and how mental events of a given type may be efficacious, qua the types of event they are---qualitative, intentional, freely deliberative---given their apparent causal irrelevancy for effects of the type in question; here we generalize what Horgan 1989 identifies as "the problem of mental quausation" (S1). We then build on this result to identify fruitful parallels between hard determinism and eliminative physicalism (S2) and soft determinism and non-reductive physicalism (S3). (shrink)

My pocket calculator (Cal) has certain arithmetical abilities: it seems Cal calculates. That calculating is thinking seems equally untendentious. Yet these two claims together provide premises for a seemingly valid syllogism whose conclusion -- Cal thinks -- most would deny. I consider several ways to avoid this conclusion, and find them mostly wanting. Either we ourselves can't be said to think or calculate if our calculation-like performances are judged by the standards proposed to rule out Cal; or the standards -- (...) e.g., autonomy and self-consciousness -- make it impossible to verify whether anything or anyone (save myself) meets them. While appeals to the intentionality of thought or the unity of minds provide more credible lines of resistance, available accounts of intentionality and mental unity are insufficiently clear and warranted to provide very substantial arguments against Cal's title to be called a thinking thing. Indeed, considerations favoring granting that title are more formidable than generally appreciated. (shrink)

This article will explore whether the law should allow people with anorexia nervosa to refuse nutrition and hydration with special reference to the English decision in Re E (Medical Treatment: Anorexia). It argues that the judge in that case made the correct decision in holding that the patient, who suffered from severe anorexia nervosa, lacked capacity to make valid advance directives under the Mental Capacity Act 2005 of the United Kingdom, and that medical procedures that are apparently against her (...) wishes should be carried out for the sake of preserving her life. The law should generally not permit patients with anorexia nervosa to decline nutrition and hydration, precisely because their autonomous ability to make such decisions has been substantially circumscribed by this psychiatric condition.

Research on spatial thinking requires reliable and valid measures of individual differences in various component skills. Spatial perspective taking (PT)—the ability to represent viewpoints different from one's own—is one kind of spatial skill that is especially relevant to navigation. This study had two goals. First, the psychometric properties of four PT tests were examined: Four Mountains Task (FMT), Spatial Orientation Task (SOT), Perspective-Taking Task for Adults (PTT-A), and Photographic Perspective-Taking Task (PPTT). Using item response theory (IRT), item difficulty, discriminability, (...) and efficiency of item information functions were evaluated. Second, the relation of PT scores to general intelligence, working memory, and mental rotation (MR) was assessed. All tasks showed good construct validity except for FMT. PPTT tapped a wide range of PT ability, with maximum measurement precision at average ability. PTT-A captured a lower range of ability. Although SOT contributed less measurement information than other tasks, it did well across a wide range of PT ability. After controlling for general intelligence and working memory, original and IRT-refined versions of PT tasks were each related to MR. PTT-A and PPTT showed relatively more divergent validity from MR than SOT. Tests of dimensionality indicated that PT tasks share one common PT dimension, with secondary task-specific factors also impacting the measurement of individual differences in performance. Advantages and disadvantages of a hybrid PT test that includes a combination of items across tasks are discussed. (shrink)

Acquisition of word meanings, or vocabulary, reflects general mental ability (psychometric g) more than than do most abilities measured in test batteries. Among diverse subtests, vocabulary is especially high on indices of genetic influences. Bloom's exposition of the psychological complexities of understanding words, involving the primacy of concepts, the theory of mind, and other processes, explains vocabulary's predominant g saturation.

Mental health generally refers to an individual’s thoughts, feelings and actions, particularly when he faced with life challenges and stresses. A good mental health isn’t just the absence of mental health problems. It is the achievement and the maintenance of psychological well-being. Mental Health is the state of one’s peace of mind, happiness and harmony brought out by one’s level of adjustment with himself and his environment. In describing mental health, Anwar said, “…mental health (...) is the health of one’s mind which can prove a potent determinant of one’s integrated personality and balanced behavour identified on the basis of the level of his adjustment to himself, others and with the environment. A mentally healthy individual possesses a number of characteristics which influence his life positively and help him in achieving his goals of life effectively. He has adequate ability to make adjustments in the changed circumstances and situations. His intellectual powers are adequately developed. He is able to think independently and take proper decision at the proper time. He tries to accomplish his work as effectively as possible but he does not prove to be an extremist by becoming a perfectionist. Though these characteristics are expected from a mentally healthy individual, but these should be taken as essential and necessary conditions for the maintenance of proper mental health and thus absence of one or the other characteristic does not necessarily mean negation of mental health. Good mental health is not just the absence of mental problems. Being mentally healthy is much more than free of depression, anxiety or other psychological issues.”1 In this paper an attempt is made to discuss about the mental health policies and issues in India.

Early in his Essays on Intellectual Powers, Reid draws a distinction between mental power, mental operation, and mental capacity (EIP 21). To the untrained eye, these terms could probably be used interchangeably, and Reid believes this is correct, up to a point. He argues that, if we are interested in understanding exactly how the human mind works, we must use these terms with more precise meanings. This is part of his more general strategy of trying to (...) always use the words with their common meanings, as much as possible, but also pointing out that certain philosophical distinctions are needed to carry out the project of laying out the foundations of the science of the mind. This paper explains what the distinction between power, operation, and capacity is, according to Reid, with the goal of understanding why it is important to draw such a distinction, not only for the Reidian project, but for action theory, more generally.

The medial temporal lobe supports both navigation and declarative memory. On this basis, a theory of phylogenetic continuity has been proposed according to which episodic and semantic memories have evolved from egocentric and allocentric navigation in the physical world, respectively. Here, we explored the behavioral significance of this neurophysiological model by investigating the relationship between the performance of healthy individuals on a path integration and an episodic memory task. We investigated the path integration performance through a proprioceptive Triangle Completion Task (...) and assessed episodic memory through a picture recognition task. We evaluated the specificity of the association between performance in these two tasks by including in the study design a verbal semantic memory task. We also controlled for the effect of attention and working memory and tested the robustness of the results by including alternative versions of the path integration and semantic memory tasks. We found a significant positive correlation between the performance on the path integration the episodic, but not semantic, memory tasks. This pattern of correlation was not explained by general cognitive abilities and persisted also when considering a visual path integration task and a non-verbal semantic memory task. Importantly, a cross-validation analysis showed that participants' egocentric navigation abilities reliably predicted episodic memory performance. Altogether, our findings support the hypothesis of a phylogenetic continuity between egocentric navigation and episodic memory and pave the way for future research on the potential causal role of egocentric navigation on multiple forms of episodic memory.

In the selection of job candidates who have the mental ability to become professional ATCOs, psychometric testing has been a ubiquitous activity in the ATM domain. To contribute to psychometric research in the ATM domain, we investigated the extent to which spatial orientation ability (SOA), as conceptualized in the spatial cognition and navigation literature, predicted air traffic conflict detection performance in a simulated free route airspace (FRA) environment. The implementation of free route airspace (FRA) over the past (...) few years, notably in Europe, have facilitated air traffic services by giving greater flexibility to aviation operators in planning and choosing preferred air routes that can lead to quicker arrivals. FRA offers enhanced system safety and efficiency, but these benefits can be outweighed by the introduction of air traffic conflicts that are geometrically more complex. Such conflicts can arise from increased number and distribution of conflict points, as well as from elevated uncertainty in aircraft maneuvering (for instance, during heading changes). Overall, these issues will make conflict detection more challenging for air traffic controllers (ATCOs). Consequently, there is a need to select ATCOs with suitably high levels of spatial orientation ability (SOA) to ensure flight safety under FRA implementation. In this study, we tested 20 participants who are eligible for ATCO job application, and found that response time-based performance on a newly developed, open access, computerized spatial orientation test (SOT) predicted time to loss of minimum separation (tLMS) performance on an air traffic conflict detection task (AT-CDT) we designed. We found this predictive relationship to be significant to a moderately large extent under scenarios with high air traffic density (raw regression coefficient = 0.58). Moreover, we demonstrated our AT-CDT as a valid test in terms of eliciting well-known mental workload and spatial learning effects. We explained these findings in light of similar or overlapping mental processes that were most likely activated optimally under task conditions featuring approximately equal numbers of outcome-relevant stimuli. We conclude by discussing the further application of the SOT to the selection of prospective ATCOs who can demonstrate high levels of conflict detection performance in FRA during training simulations.

Legal reasoning settles morally pressing matters through a technique that largely bypasses open-ended moral argument. That technique makes central what certain persons validly decided in the past, for example in creating statutes, judicial resolutions, contracts, or wills. Identifying valid decisions is a lawyerly skill and, echoing legal practice, legal philosophy has paid considerable attention to validity criteria. But it has neglected to explore validity's point: whether, and if so exactly how, the special technique of validity contributes to (...) a legal system's ability to realise justice and human rights. Even the most sensible defences of the moral need for positive law have insufficiently probed this key step in the argument. This book lays bare the workings of legal validity, and shows why, and within what general limits, this technique equips legal systems with privileged tools to foster human well-being. In so doing, the book explains how power-conferring norms setting out validity criteria endow agents' intentions with 'performative' effect ('I hereby.') and can secure the requirement of justice that there be widespread convergence on specific patterns of conduct shaped through a cooperative effort. Legal meaning is accordingly systemic, resulting from the valid acts of multiple agents whose decisions can, by virtue of exercising legal power, also exercise moral power (authority). In short, the book articulates why it is morally necessary that validity does not primarily turn on moral considerations. (shrink)

A diagnosis of schizophrenia is often taken to denote a state of global irrationality within the psychiatric paradigm, wherein psychotic phenomena are seen to equate with a lack of mental capacity. However, the little research that has been undertaken on mental capacity in psychiatric patients shows that people with schizophrenia are more likely to experience isolated, rather than constitutive, irrationality and are therefore not necessarily globally incapacitated. Rational suicide has not been accepted as a valid choice for people (...) with schizophrenia due in part to a belief that characteristic irrationality prevents autonomous decision-making. Since people with schizophrenia are often seen to lack insight into the nature of their disorder, both psychiatric and ethical perspectives generally presume that suicidal acts result directly from mental illness itself and not from second-order desires. In this article, I challenge notions of global irrationality conferred by a diagnosis of schizophrenia and argue that, where delusional beliefs are unifocal, schizophrenia does not necessarily lead to a state of mental incapacity. I then attempt to show that people with schizophrenia can sometimes be rational with regard to suicide, where this decision stems from a realistic appraisal of psychological suffering. (shrink)

Recent legal developments challenge how valid the concept of mental capacity is in determining whether individuals with impairments can make decisions about their care and treatment. Kong defends a concept of mental capacity but argues that such assessments must consider how relationships and dialogue can enable or disable the decision-making abilities of these individuals. This is thoroughly investigated using an interdisciplinary approach that combines philosophy and legal analysis of the law in England and Wales, the European Court of (...) Human Rights, and the United Nations Convention on the Rights of Persons with Disabilities. By exploring key concepts underlying mental capacity, the investigation concludes that both primary relationships and capacity assessments themselves must display key competencies to ensure that autonomy skills are promoted and encouraged. This ultimately provides scope for justifiable interventions into disabling relationships and articulates the dialogical practices that help better situate, interpret, and understand the choices and actions of individuals with impairments.

The information processing capacity of the human mind is limited, as is evidenced by the so-called ‘‘attentional-blink’’ deficit: When two targets (T1 and T2) embedded in a rapid stream of events are presented in close temporal proximity, the second target is often not seen. This deficit is believed to result from competition between the two targets for limited attentional resources. Here we show, using performance in an attentional-blink task and scalp-recorded brain potentials, that meditation, or mental training, affects the (...) distribution of limited brain resources. Three months of intensive mental training resulted in a smaller attentional blink and reduced brain-resource allocation to the first target, as reflected by a smaller T1-elicited P3b, a brain-potential index of resource allocation. Furthermore, those individuals that showed the largest decrease in brain-resource allocation to T1 generally showed the greatest reduction in attentional-blink size. These observations provide novel support for the view that the ability to accurately identify T2 depends upon the efficient deployment of resources to T1. The results also demonstrate that mental training can result in increased control over the distribution of limited brain resources. Our study supports the idea that plasticity in brain and mental function exists throughout life and illustrates the usefulness of systematic mental training in the study of the human mind. (shrink)

This target article considers the relation of fluid cognitive functioning to general intelligence. A neurobiological model differentiating working memory/executive function cognitive processes of the prefrontal cortex from aspects of psychometrically defined general intelligence is presented. Work examining the rise in mean intelligence-test performance between normative cohorts, the neuropsychology and neuroscience of cognitive function in typically and atypically developing human populations, and stress, brain development, and corticolimbic connectivity in human and nonhuman animal models is reviewed and found to provide (...) evidence of mechanisms through which early experience affects the development of an aspect of cognition closely related to, but distinct from, general intelligence. Particular emphasis is placed on the role of emotion in fluid cognition and on research indicating fluid cognitive deficits associated with early hippocampal pathology and with dysregulation of the hypothalamic-pituitary-adrenal axis stress-response system. Findings are seen to be consistent with the idea of an independent fluid cognitive construct and to assist with the interpretation of findings from the study of early compensatory education for children facing psychosocial adversity and from behavior genetic research on intelligence. It is concluded that ongoing development of neurobiologically grounded measures of fluid cognitive skills appropriate for young children will play a key role in understanding early mental development and the adaptive success to which it is related, particularly for young children facing social and economic disadvantage. Specifically, in the evaluation of the efficacy of compensatory education efforts such as Head Start and the readiness for school of children from diverse backgrounds, it is important to distinguish fluid cognition from psychometrically defined general intelligence.

Emotional Intelligence (EI) has been conceptualized in the literature either as a dispositional tendency, in line with a personality trait (trait EI; Petrides and Furnham, 2001), or as an ability, moderately correlated with general intelligence (ability EI; Mayer and Salovey, 1997). Surprisingly, there have been few empirical attempts conceptualizing how the different EI approaches should be related to each other. However, understanding how the different approaches of EI may be interwoven and/or complementary is of primary importance for (...) clarifying the conceptualization of EI and organizing the literature around it. We introduce a theoretical framework explaining how trait EI, ability EI, and emotion information processing – a novel component related to EI recently introduced in the literature (e.g., Fiori and Vesely Maillefer, 2018) – may contribute to effective emotion-related performance and provide initial evidence supporting its usefulness in predicting EI-related outcomes. More specifically, we show that performance in a task in which participants had to infer the mental and emotional states of others, namely a Theory of Mind task, was predicted jointly (e.g., interaction effects) by trait EI, ability EI, and emotion information processing, after controlling for personality and IQ (N = 323). Our results argue for the importance of investigating the joint contribution of different aspects of EI in explaining variability in emotionally laden outcomes. (shrink)

Our ability to attribute mental states to others ("to mentalize") has been the subject of philosophical and psychological studies for a very long time, yet the role of language acquisition in the development of our mentalizing abilities has been largely understudied.

The work provides the reader with detailed and critical literature reviews, and draws on them to argue that language acquisition helps false belief reasoning by boosting the ability to create schemata that facilitate processing of information in some social contexts.

Defined as vicarious sensorimotor experiencing, mental imagery is a powerful source of aesthetic enjoyment in everyday life and, reportedly, one of the commonest things readers remember about literary narratives in the long term. Furthermore, it is positively correlated with other dimensions of reader response, most notably with emotion. Until recent decades, however, the phenomenon of mental imagery has been largely overlooked by modern literary scholarship. As an attempt to strengthen the status of mental imagery within the literary (...) and, more generally, aesthetic discipline, this dissertation proposes an analysis positioned at a confluence of literary theory and the cognitive sciences, especially the emergent research framework of embodied cognition. Questions asked throughout the dissertation include the following: a) What are the basic varieties of mental imagery in the reading of literary narrative? b) By what contents or narrative strategies are they most likely to be prompted? c) What is it like to experience a mental image of a particular variety? d) What are its psychophysiological underpinnings? e) How does a mental image of a particular variety relate to perception? f) How does it relate to higher-order meaning-making? Four prototypical imagery varieties are distinguished on the basis of two variables with two values each (referential vs. verbal domain; inner vs. outer stance). Gradual transitions and in-between imagery varieties are acknowledged. The imagery typology and related hypotheses are grounded in introspection but carefully supported with indirect empirical evidence and, whenever possible, formulated so as to facilitate direct validation.

Consciousness, as a higher-order cognitive capacity allowing for the explicit representation of abstract mental states, might be the incidental byproduct of design features from other adaptive systems, such as those governing expansion of the frontal lobes in primates. Although such abilities may have occurred entirely by chance, the standardized entrenchment of this representational capacity in human cognition may have posed engineering dilemmas for natural selection in that consciousness could not be easily removed without disrupting the adaptive features of other (...) design solutions. If so, then those organisms saddled with the burden of higher-order representation by the occurrence of these chance events were suddenly assaulted with a series of social problems previously unencountered by any other species in evolutionary history. Such consciousness-based problems constituted enormous selective pressure for generating ancestrally adaptive psychological programs designed to cope with them. Each of these design solutions was, by necessity, generated and progressively pruned over an extraordinarily short span of geological time. In addition, these programs ran into conflict with more ancient primate social adaptations — such as those underlying sexual coercion and violence — that did not evolve to be sensitive to the epistemic positions of others. These mosaic processes have likely resulted in selection for innumerable algorithmic properties driving human-specific behaviors which are both proximally and ultimately caused by consciousness. Consciousness by itself should be classified as maladaptive; what is adaptive are those psychological programs in place to support its incidental and problematic arrival in the human brain. (shrink)

Recent literature have underlined the connections between children’s reading skills and capacity to create and use mental representations or mental images; furthermore data highlighted the involvement of visuospatial abilities both during math learning and during subsequent developmental phases in performing math tasks. The present research adopted a longitudinal design to assess whether the processes of mental imagery in preschoolers (ages 4–5 years) are predictive of mathematics skills, writing and reading, in the early years of primary school (ages (...) 6–7 years). The research lasted for two school years; in the first phase, the general group of participants consisted of 100 children, and although all participants agreed to be part of the research, in the second phase, there was a mortality rate of 30%. In order to measure school learning and mental imagery processes four batteries of tests were used. The mental imagery battery evaluated mental generation, inspection and transformation processes. Data underlined that the different aspects in which mental imagery processes are articulated are differently implied in some skills that constitute school learning. These findings emphasise the potential usefulness of a screening for mental imagery ability for schoolchildren to adopt effective measures to increase their mental imagery abilities. (shrink)

This book analyses the role of diagrammatic reasoning in Plato’s philosophy: the readers will realize that Plato, describing the stages of human cognitive development using a diagram, poses a logic problem to stimulate the general reasoning abilities of his readers. Following the examination of mental models in this book, the readers will reflect on what inferences can be useful to approach this kind of logic problem. Plato calls for a collaboration between writer and readers. In this book the (...) readers will examine the connection between diagrams and discovery, realizing the important epistemic role of visualization. They will recognize the crucial role that diagrams play in problem solving. The logic problem elaborated by Plato is addressed considering the epistemic function of mental models. These models introduce to an advanced stage of cognitive development, in which reasoning uses in its investigations a higher-level of mathematical complexity, represented by structuralism. (shrink)

Body awareness refers to the individual ability to process signals originating from within the body, which provide a mapping of the body’s internal landscape and its relation with space and movement. The present study aims to evaluate psychometric properties and validate in French two self-report measures of body awareness: the Postural Awareness Scale, and the last version of the Multidimensional Assessment of Interoceptive Awareness questionnaire. We collected data in a non-clinical, adult sample using online survey, and a subset of (...) the original sample also completed the retest control. Factor analyses and reliability analyses were conducted. Construct validity of the PAS and the MAIA-2 were examined by testing their association with each other, and with self-report measures of personality, alexithymia and dispositional trait mindfulness. Factor analyses of the PAS supported the same two-factor structure as previously published versions. For the MAIA-2, factor analyses suggested that a six-factor structure, excluding Not-Worrying and Not-Distracting factors, could successfully account for a common general factor of self-reported interoception. We found satisfactory internal consistency, construct validity, and reliability over time for both the PAS and the MAIA-2. Altogether, our findings suggest that the French version of the PAS and the MAIA-2 are reliable self-report tools to assess both components of body awareness. (shrink)

Mental rotation of emotional and neutral stimuli The main aim of the study was to create and validate emotional version of mental rotation task. As all previously conducted experiments utilized neutral material only, such an attempt seemed necessary to confirm the generality of mental rotation effect and its properties. Emotional MRT was constructed using photos of negative facial expressions; a compatible neutral MRT was also created, for detailed comparisons. 2- and 3-dimensional figures and hexagrams served as affect-free (...) stimuli. In three experiments, emotional MRT version was proven to be valid, whereas only hexagram-based neutral MRT version yielded the expected results. A number of differences between the two versions emerged, concerning response times, accuracy and difficulty of trials. The neutral/emotional MRT procedure, although needing more research, seems to give stable results, making the study of content-bound imagery possible. (shrink)

Background and aimsThe COVID-19 pandemic has been accompanied by a worsening of mental health levels in some, while others manage to adapt or recover relatively quickly. Transdiagnostic factors such as personality functioning are thought to be involved in determining mental health outcomes. The present study focused on two constructs of personality functioning, Criterion A of the Alternative Model for Personality Disorders and mentalization, as predictors of depressive symptoms and life satisfaction during the COVID-19 pandemic. A second focus of (...) the study was to examine whether this relationship was mediated by resilience.MethodsLinear regression analyses were used to examine the relationship between personality functioning measured by Criterion A and mentalizing abilities as predictors, and depression and life satisfaction as mental health outcomes. To assess the hypothesis that this relationship is mediated by resilience a structural equation modeling approach was conducted. Data from N = 316 individuals from the general population were collected.ResultsLinear regression models revealed highly significant associations between Criterion A/mentalization and both outcome measures. Structural equation models showed a significant partial mediation by resilience of these relationships.ConclusionOur results support the hypothesis that mentalizing serves as a protective function by promoting resilience to the impact of stress and threats. Criterion A and mentalization performed similarly as predictors of mental health outcomes, providing empirically overlapping operationalizations of personality functioning.
