If the words of natural human language possess a universal positivity bias, as assumed by Boucher and Osgood’s (1969) famous Pollyanna hypothesis and computationally confirmed for large text corpora in several languages (Dodds et al., 2015), then children and youth literature (CYL) should also show a Pollyanna effect. Here we tested this prediction applying a vector space model- based sentiment analysis tool called SentiArt (Jacobs, 2019) to two CYL corpora, one in English (372 books) and one in German (...) (500 books). Pitching our analysis at the sentence level, and assessing semantic as well as lexico-grammatical information, bBoth corpora show the Pollyanna effect and thus add further evidence to the universality hypothesis. The results of our multivariate sentiment analyses provide interesting testable predictions for future scientific studies of literature. (shrink)

Ethical conduct is the hallmark of excellence in engineering and scientific research, design, and practice. While undergraduate and graduate programs in these areas routinely emphasize ethical conduct, few receive formal ethics training as part of their curricula. The first purpose of this research study was to assess the relative effectiveness of ethics education in enhancing individuals’ general knowledge of the responsible conduct of research practices and their level of moral reasoning. Secondly, we examined the effects of ethics education on the (...) positive psychological outcomes of perspective-taking, moral efficacy, moral courage, and moral meaningfulness. To examine our research hypotheses, we utilized a pretest–posttest quasi-experimental design consisting of three ethics education groups (control, embedded modules, and stand-alone courses). Findings revealed that both embedded and stand alone courses were effective in enhancing participants’ perspective-taking, moral efficacy, and moral courage. Moral meaningfulness was marginally enhanced for the embedded module condition. Moral judgment and knowledge of responsible conduct of research practices were not influenced by either ethics education condition. Contrary to expectations, stand alone courses were not superior to embedded modules in influencing the positive psychological outcomes investigated. Implications of these findings for future research and practice are discussed. (shrink)

Cognitively engaging physical activity has been suggested to have superior effects on cognition compared to PA with low cognitive demands; however, there have been few studies directly comparing these different types of activities. The aim of this study is to compare the cognitive effects of a combined physically and cognitively engaging bout of PA to a physical or cognitive activity alone in children. Children were randomized in pairs to one of three 20-min conditions: a cognitive sedentary activity; a non-cognitively engaging (...) PA; and a cognitively engaging PA. Executive function was assessed using a modified Eriksen flanker task immediately before and 10–15 min following the experimental condition. Children ages 6–8 years were included in the study. A repeated measures ANOVA found no significant difference between groups with respect to scores on the flanker task. The results do not support the hypotheses that a cognitively engaging bout of PA enhances cognitive performance over non-cognitively engaging PA or sedentary activities. Possible explanations for our findings include overexertion during the acute bout of PA and depletion of positive affect prior to performing the post-intervention EF tasks. (shrink)

Within the ethics and science literature surrounding uterus transplantation (UTx), emphasis is often placed on the extent to which UTx might improve upon, or offer additional benefits when compared to, existing ‘treatment options’ for women with absolute uterine factor infertility, such as adoption and gestational surrogacy. Within this literature UTx is often positioned as superior to surrogacy because it can deliver things that surrogacy cannot (such as the experience of gestation). Yet, in addition to claims that UTx is superior in (...) the aforementioned sense it is also often assumed (either implicitly or explicitly) that UTx is less fraught with ethical difficulties and thus should be considered a less morally problematic option. This article seeks to examine this assumption. Given that much UTx research has been performed in Sweden, a country where surrogacy is effectively although not currently explicitly forbidden, we do this through an analysis of the arguments underpinning a 2016 Swedish white paper which considered amending existing policy such that altruistic surrogacy arrangements would be permitted. By applying the white paper’s arguments for a restrictive position on altruistic surrogacy to the case of UTx using living altruistic donors we find that such arguments, if they hold in the case of surrogacy, apply similarly to UTx. We thus suggest that, for reasons of consistency, a similar stance should be taken towards the moral and legal permissibility of these two practices. (shrink)

The aim of this study was to explain previous inconsistent results regarding the effects of positive affect on creative cognition based on the motivational dimensional model of affect theory and provide the underlying neural correlates of the effects of different approach-motivation intensities of positive affect on creative processes (creative idea generation and creative idea evaluation) using the functional near-infrared spectroscopy (fNIRS) technique. Sixty participants were randomly assigned to three groups (high-approach-motivated positive affect (HAM), low-approach-motivated positive affect (LAM) and affectively neutral (...) state (NS)) to complete corresponding tasks in creative idea generation and creative idea evaluation stages. In the creative idea generation stage, the results indicated that the LAM group achieved a higher performance in flexibility and originality than the NS group. However, compared with the NS group, the LAM group exhibited a lower sensitivity in the creative idea evaluation stage. The fNIRS technique provides an ideal approach with high ecological validity for exploring the issue of affect and creativity. In current study, fNIRS results showed that the HAM group exhibited significantly more activation in the bilateral frontal lobe than the LAM group and NS group in the creative idea generation stage. This result could reflect individuals attempting to overcome a narrowed attentional scope state through the activation of bilateral frontal cortical resources in the creative process. In the creative idea evaluation stage, compared with the NS group, the LAM group showed significant deactivation in the right dorsolateral prefrontal cortex, which is a brain area associated with executive, controlled processing. Moreover, the approach-motivation intensity altered the connectivity between the left prefrontal cortex and left superior temporal gyrus in the creative idea generation stage. Thus, the influences of positive affect on creative cognitive processes (both creative performance and hemodynamic responses) were modulated by the approach-motivation intensity in the creative idea generation and creative idea evaluation stages.

Prefrontal cortex is dysregulated in women with restricting anorexia nervosa . It is not known whether appetitive non-conscious stimuli bias cognitive responses in those with RAN. Thirteen women with RAN and 20 healthy controls completed a dorsolateral PFC working memory task and an anterior cingulate cortex conflict task, while masked subliminal food, aversive and neutral images were presented. During the DLPFC task, accuracy was higher in the RAN compared to the HC group, but superior performance was compromised when subliminal food (...) stimuli were presented: errors positively correlated with self-reported trait anxiety in the RAN group. These effects were not observed in the ACC task. Appetitive activation is intact and anxiogenic in women with RAN, and non-consciously interacts with working memory processes associated with the DLPFC. This interaction mechanism may underlie cognitive inhibition of appetitive processes that are anxiety inducing, in people with AN. (shrink)

In this study, we examined the word superiority effect in Arabic and English, two languages with significantly different morphological and writing systems. Thirty-two Arabic–English bilingual speakers performed a post-cued letter-in-string identification task in words, pseudo-words, and non-words. The results established the presence of the word superiority effect in Arabic and a robust effect of context in both languages. However, they revealed that, compared to the non-word context, word and pseudo-word contexts facilitated letter identification more in (...) Arabic than in English. In addition, the difference between word and pseudo-word contexts was smaller in Arabic compared to English. Finally, there was a consistent first-letter advantage in English regardless of the context, while this was more consistent only in the word and pseudo-word contexts in Arabic. We discuss these results in light of previous findings and argue that the differences between the patterns reported for Arabic and English are due to the qualitative difference between word morphophonological representations in the two languages.

What signals do firms in emerging economies send to stakeholders when they adopt corporate social responsibility practices? We argue that in emerging economies, firms that adopt CSR practices positively signal investors that their firms have superior capabilities for filling institutional voids. From an institution-based view, we hypothesize that the institutional environment moderates the signaling effect of CSR on a firm’s financial performance. Based on a sample of firms from ten Asian emerging economies, we find a positive relationship between CSR (...) practices and financial performance. This positive relationship is stronger in the less developed capital market than in the more developed one. The financial benefits of CSR practices are also more salient in the low information diffusion market than in the high one. We emphasize that signaling theory and the institution-based view can jointly contribute to the CSR literature. (shrink)

The face is a powerful source to make inferences about one’s trustworthiness. Recent studies demonstrated that facial trustworthiness is influenced by the level of threat conveyed by the visual scene in which faces are embedded: untrustworthy-looking faces are more likely judged as untrustworthy when shown in threatening scenes. Here, we explore whether this face-context congruency effect is specific to the negative pole of the threat-trust domain. Experiment 1 (N = 89) focused on the differential impact of positive vs. negative (...) face-context congruency within the domains of threat and trust. Negative congruency (i.e. untrustworthy-looking faces in threatening contexts) led to more extreme attributions as opposed to positive congruency (i.e. trustworthy-looking faces in reassuring contexts). Experiment 2 (N = 120) replicated these findings by further showing their domain-specificity. The negativity bias was found in the threat-trust domain, but not when extroverted- vs. introverted-looking faces appeared in happy vs. sad context scenes. Experiment 3 (N = 154, pre-registered) replicated the pattern observed in Experiment 1 while controlling for the extent to which both threatening and reassuring context stimuli were related to the human action. We discussed the theoretical implications of these results for understanding how contextual information is integrated into the evaluation of facial trustworthiness. (shrink)

How learning a second language changes our brain has been an important question in neuroscience. Previous neuroimaging studies with different ages and language pairs spoken by bilinguals have consistently shown plastic changes in brain systems supporting executive control. One hypothesis posits that L2 experience-induced neural changes supporting cognitive control, which is responsible for the selection of a target language and minimization of interference from a non-target language. However, it remains poorly understood as to whether such cognitive advantage is reflected as (...) stronger controlled processing or increased automatic inhibition processing. In this study, using functional MRI we scanned 27 Chinese-English late bilinguals while they performed a Simon task. Results showed that bilinguals with higher L2 vocabulary proficiency performed better in the Simon task, and more importantly, higher L2 vocabulary proficiency was associated with weaker activation of brain regions that support more general cognitive control, including the right anterior cingulate cortex, left insula and left superior temporal gyrus. These results suggest that L2 experience may lead to a more automatic and efficient processing in the inhibitory control task. Our finding provides an insight into neural activity changes associated with inhibitory control as a function of L2 proficiency. (shrink)

It has been suggested that external and/or internal limitations paradoxically may lead to superior learning, that is, the concepts of starting small and less is more (Elman, ; Newport, ). In this paper, we explore the type of incremental ordering during training that might help learning, and what mechanism explains this facilitation. We report four artificial grammar learning experiments with human participants. In Experiments 1a and 1b we found a beneficial effect of starting small using two types of simple (...) recursive grammars: right‐branching and center‐embedding, with recursive embedded clauses in fixed positions and fixed length. This effect was replicated in Experiment 2 (N = 100). In Experiment 3 and 4, we used a more complex center‐embedded grammar with recursive loops in variable positions, producing strings of variable length. When participants were presented an incremental ordering of training stimuli, as in natural language, they were better able to generalize their knowledge of simple units to more complex units when the training input “grew” according to structural complexity, compared to when it “grew” according to string length. Overall, the results suggest that starting small confers an advantage for learning complex center‐embedded structures when the input is organized according to structural complexity. (shrink)

Recent brain imaging studies using functional magnetic resonance imaging (fMRI) have implicated insula and anterior cingulate cortices in the empathic response to another’s pain. However, virtually nothing is known about the impact of the voluntary generation of compassion on this network. To investigate these questions we assessed brain activity using fMRI while novice and expert meditation practitioners generated a loving-kindness-compassion meditation state. To probe affective reactivity, we presented emotional and neutral sounds during the meditation and comparison periods. Our main hypothesis (...) was that the concern for others cultivated during this form of meditation enhances affective processing, in particular in response to sounds of distress, and that this response to emotional sounds is modulated by the degree of meditation training. The presentation of the emotional sounds was associated with increased pupil diameter and activation of limbic regions (insula and cingulate cortices) during meditation (versus rest). During meditation, activation in insula was greater during presentation of negative sounds than positive or neutral sounds in expert than it was in novice meditators. The strength of activation in insula was also associated with self-reported intensity of the meditation for both groups. These results support the role of the limbic circuitry in emotion sharing. The comparison between meditation vs. rest states between experts and novices also showed increased activation in amygdala, right temporo-parietal junction (TPJ), and right posterior superior temporal sulcus (pSTS) in response to all sounds, suggesting, greater detection of the emotional sounds, and enhanced mentation in response to emotional human vocalizations for experts than novices during meditation. Together these data indicate that the mental expertise to cultivate positive emotion alters the activation of circuitries previously linked to empathy and theory of mind in response to emotional stimuli..

This paper employs data from a sample of the CEOs and top managers of seventy-nine U.S. companies and non-profit organizations to test hypotheses concerning the effects of the salience of organizational values on the accuracy of top managers’ perceptions of their CEOs’ values and their propensities to project their own values onto their CEOs. Results provide evidence that the salience of organizational values is positively related to both accuracy in subordinates’ perceptions of their superiors’ values and projection of the subordinates’ (...) values onto their superiors. This initially counterintuitive result is explained with reference to contemporary views of projection as a heuristic rather than as a non-normative bias that results in the cognitive distortion of reality.

Most studies have shown that reading is an important source of incidental vocabulary learning, and repeated reading may have a positive effect on learning gains. However, the study of incidental vocabulary learning through listening is still limited, and the immediate and long-term effects on different vocabulary knowledge dimensions are unclear. Furthermore, no empirical studies have been conducted to investigate the association between learning gains and preexisting vocabulary knowledge in listening. This article examines the effects of listening to English songs (...) on unintentional vocabulary learning and vocabulary retention through three different vocabulary knowledge dimensions: word recognition, meaning association, and grammar identification. A total of 114 Chinese college students participated in the study, and they were given vocabulary evaluations at different times based on three separate components of vocabulary knowledge. The effects of repeated listening and learners’ prior vocabulary knowledge were also investigated. According to the findings, listening to songs can improve vocabulary knowledge, particularly in the area of word recognition, which can be retained 4 weeks later. Furthermore, the effect of listening three times was superior than listening one or five times, which provides teachers and learners with guidance for teaching or learning vocabulary more effectively. Finally, for low, intermediate, and high-level learners, there was an immediate and positive effect on the dimensions of word recognition and meaning connection after listening, and this knowledge is likely to be preserved 4 weeks later.

Poor university students are a special group. Social development provides many positive factors for poor university students’ personality and psychological development, but negative factors are also accompanied by them, which affect the psychological health of poor university students. University students are in a period of rapid physical and mental development, and it is an important issue that colleges and universities need to solve psychological well-being education. We hope to find out the aspects that can be studied in the irregularity of (...) various factors that affect college students’ mental health. BP neural network is a typical model of artificial neural network. Based on the BP algorithm and the fuzzy comprehensive evaluation of the psychological well-being prediction system for poor university students, this paper systematically summarizes the concept of psychological well-being, the factors that affect psychological well-being, and the related research done by predecessors on psychological well-being. Using the international psychological well-being scale SCL-90 to comprehensively consider the psychological well-being status of poor university students and select the optimized BP algorithm to establish a psychological well-being prediction model, and implement it and compare it with other models to reflect its superiority. Data were collected and analyzed by means of a questionnaire. The regression model was used to analyze the relationship between mindfulness, rumination and psychological well-being. The mediation index fitted by the model reached 0.9. The model can reflect the real situation of the data, that is, rumination plays a partial mediating role in the effect of mindfulness on psychological well-being. The introduction of this psychological prediction model into the psychological well-being education of poor university students not only helps to improve the educational concept and expand the educational approach, but also helps to achieve the goal of psychological well-being education for poor university students, thereby promoting the improvement of the psychological quality of poor university students.

Prosocial behavior is critical for the natural development of an individual as well as for promoting social relationships. Although this complex behavior results from gratuitous acts occurring between an agent and a recipient and a wealth of literature on prosocial behavior has investigated these actions, little is known about the effects on the recipient and the neurobiology underlying them. In this study, we used functional magnetic resonance imaging to identify neural correlates of receiving prosocial behavior in the context of real-world (...) experiences, with different types of action provided by the agent, including practical help and effort appreciation. Practical help was associated with increased activation in a network of regions spanning across bilateral superior temporal sulcus, temporoparietal junction, temporal pole, and medial prefrontal cortex. Effort appreciation was associated with activation and increased task-modulated connectivity of the occipital cortex. Prosocial-dependent brain responses were associated with positive affect. Our results support the role of the theory of mind network and the visual cortices in mediating the positive effects of receiving gratuitous help. Moreover, they indicate that specific types of prosocial behavior are mediated by distinct brain networks, which further demonstrates the uniqueness of the psychological processes underlying prosocial actions.

Smiles provide information about a social partner’s affect and intentions during social interaction. Although always encountered within a specific situation, the influence of contextual information on smile evaluation has not been widely investigated. Moreover, little is known about the reciprocal effect of smiles on evaluations of their accompanying situations. In this research, we assessed how different smile types and situational contexts affected participants’ social evaluations. In Study 1, 85 participants rated reward, affiliation, and dominance smiles embedded within either enjoyable, (...) polite, or negative (unpleasant) situations. Context had a strong effect on smile ratings, such that smiles in enjoyable situations were rated as more genuine and joyful, as well as indicating less superiority than those in negative situations. In Study 2, 200 participants evaluated the situations that these smiles were perceived within (rather than the smiles themselves). Although situations paired with reward (vs. affiliation) smiles tended to be rated more positively, this effect was absent for negative situations. Ultimately, the findings point toward a reciprocal relationship between smiles and contexts, whereby the face influences evaluations of the situation and vice versa. (shrink)

Previous research suggests that implicit sequence learning is superior for believers in the paranormal and individuals with increased cerebral dopamine. Thirty-five healthy participants performed feedback-guided anticipations of four arrow directions. A 100-trial random sequence preceded two 100-trial biased sequences in which visual targets on trial t tended to be displaced 90° clockwise or counter-clockwise from those on t − 1. ISL was defined as a positive change during the course of the biased run in the difference between pro-bias and counter-bias (...) responses. It was hypothesized that this difference would be greater for believers in the paranormal than for skeptics, for those who received dopamine than for those who received placebo, and for believers who received dopamine than for the other groups. None of the hypotheses were supported by the data. It is suggested that a simple binary guessing task with a focus on prediction accuracy during early trials should be considered for future explorations. (shrink)

Although awareness of cultural differences that distinguish Indigenous peoples has increased worldwide following attention from international human rights bodies, Indigenous cultural values have had little influence in shaping research agendas or methods of inquiry. Self‐determination and reconciliation policies have been part of the decolonisation agenda of governments for several decades; however, these have not, until recently, been considered of relevance to research. Indigenous peoples feel that they are the most studied population in Australia, to the point where even the word (...) research arouses feelings of suspicion and defensive attitudes. Indigenous people are generally cynical about the benefits of research and cautious toward what many perceive to be the colonial mentality or ‘positional superiority’ ingrained in the psyche of western researchers. This article examines the characteristics and colonising effects of traditional research methods and describes an alternative, decolonising approach. Decolonising research methodology is congruent with Indigenous epistemology and is guided by the values and research agenda of Indigenous people. TheGuidelines for ethical conduct in Aboriginal and Torres Strait islander health research, developed by the National Aboriginal and Islander Health Organisation (NAIHO) with the National Health & Medical Research Council (NHMRC) in 2003 are examined, as they exemplify a decolonising paradigm for researchers.

Angry faces have been shown to be detected more efficiently in a crowd of distractors compared to happy faces, known as the anger superiority effect (ASE). The present study investigated whether the ASE could be modified by top-down manipulation of working memory (WM), in central and peripheral visual fields. In central vision, participants held a colour in WM for a final memory test while simultaneously performing a visual search task that required them to determine whether a face showed (...) a different expression from other coloured faces. The colour held in WM matched either the colour of the target face (target-matching), the colour of a distractor face (distractor-matching), or neither (non-matching). Results showed that the ASE was observed when the probability of target-matching trials was low. However, when the top-down WM effect was strengthened by raising the probability of target-matching trials, the ASE in the target-matching condition was completely eliminated. Intriguingly, when the visual search task was substituted by a peripheral crowding task, similar results to central vision were found in the target-matching condition. Taken together, our findings indicate that the ASE is subject to the top-down WM effect, regardless of the visual field. (shrink)

This exploration aims to solve the problems of imperfect psychological health education system and poor educational effects on college students. Here, ideological and political education is integrated with mental health education to investigate the role of collaborative intervention in guiding college students to resist negative emotions. First, an overview is offered of research on ideological and political education, mental health education, and negative emotions by the literature survey method. Moreover, a comprehensive investigation is also conducted on research objects, through the (...) questionnaire, to understand the current situation of negative emotions of college students. And finally, an intervention experiment is taken on the negative emotions of college students by combining ideological and political education with mental health education. The results show that after 10 weeks of intervention experiment by combining ideological and political education with mental health education, there are significant differences in depression, negative emotions, somatization symptoms, and interpersonal problems between the treatment group and the control group. Besides, there are significant differences in depression, negative emotions, somatization symptoms, and interpersonal problems between sophomores in the treatment group and the control group. Moreover, there are significant differences in depression, negative emotions, somatization symptoms, and interpersonal problems between male participants in the treatment group and the control group. In summary, ideological and political education integrated with mental health education has a positive guidance effect on the negative emotions of college students, greatly improving the negative emotions of the students, helping the students to regulate their emotions, and benefiting their study and life a lot. The purpose of integrating ideological and political education with mental health education is to provide reference for refining the mental health education system of college students and strengthening the positive guidance of negative emotions of college students.

Jessica Brown effectively contends that Keith DeRose’s latest argument for contextualism fails to rule out contextualism’s chief rival, namely, classic invariantism. Still, even if her position has not been ruled out, the classic invariantist must offer considerations in favor of her position if she is to convince us that it is superior to contextualism. Brown defends classic invariantism with a warranted assertability maneuver that utilizes a linguistic pragmatic principle of relevance. I argue, however, that this maneuver is not as effective (...) as it might be. I propose a different warranted assertability maneuver—one that utilizes a pragmatic principle of strength—that affords a more successful defense of classic invariantism, and that helps to establish that classic invariantism is superior to contextualism.

Previous studies suggest that ancient threats capture attention because human beings possess an inborn module shaped by evolution and dedicated to their detection. An alternative account proposes that a key feature predicting whether a stimulus will capture attention is its relevance rather than its ontology. Within this framework, the present research deals with the attentional capture by threats commonly encountered in our urban environment. In two experiments, we investigate the attentional capture by modern threats. In Experiment 1, participants responded to (...) a target preceded by a cue, which was a weapon or a non-threatening stimulus. We found a larger cuing effect with weapons as compared with non-threatening cues. In Experiment 2, modern and ancient threats were pitted against one another as cues to determine which ones preferentially capture attention. Crucially, participants were faster to detect a target preceded by a modern as opposed to an ancient threat, providing initial evidence for a superiority of modern threat. Overall, the present findings appear more consistent with a relevance-based explanation rather than an evolutionary-based explanation of threat detection. (shrink)

An increasing number of drugs removed from the market because of unacceptable toxicity raises concerns regarding preapproval testing of drug safety. In the present paper it is postulated that the non-inferiority type of trial should be abandoned in favor of the superiority trial with active controls and less stringent (p<0.1, both for efficacy and toxicity) statistics. This approach will increase sensitivity of detection of drug-induced adverse effects at the expense of increasing false positive results regarding the difference in efficacy (...) between the tested and reference drug. Such a move will increase the protection of future patients. In addition, the proposed design is far more acceptable from the clinical (e.g. no need to specify the statistically expected “unimportant” number of deaths) and ethical points of view, as well as being favored by the strong incentive of involved parties. In the second part of this paper arguments are presented in favor of the hypothesis that placebo (still used in some superiority trials) does not induce adverse effects. The assertion that placebo may induce adverse effects is probably biased by the nature of the clinical experiment. Such a conclusion is supported by studies indicating that placebo-induced adverse effects are disease — and treatment — specific. The modification of clinical trials according to the proposed changes may increase the trials’ sensitivity at detecting adverse effects of drugs. (shrink)

Extant research indicates a positive and significant relationship between corporate ethical values and employees’ job performance. Furthermore, past studies have empirically demonstrated that perceived fairness moderates the influence of corporate ethical values on employee performance. In other words, high congruity between employees’ and an organization’s ethical values will result in superior employee performance outcome. This research aims to develop a broader perspective on the complex relationship between CEV and employee outcomes. The article will first examine the direct influence of CEV (...) on organizational citizenship behaviors and alienation from work, and then the moderating role of perceived fairness. The researcher found a significant direct effect of CEV on both OCBs and AFW, but that perceived fairness does not moderate these relationships. A key implication of findings of this research is that although perception of fairness may suppress the impact of organizational ethical transgressions on employee performance in the short run, as earlier studies have demonstrated, but in the long term, implications of perceived fairness are multifold.

Positive spillover occurs when changes in one behaviour influence changes in subsequent behaviours. Evidence for such spillover and an understanding of when and how it may occur is still limited. This paper presents findings of a one year longitudinal behaviour change project led by a commercial retailer in the UK & Ireland to examine behaviour change and potential spillover of pro-environmental behaviour, and how this may be associated with changes in environmental identity and perceptions of ease and affordability as well (...) as perceptions of how participation in the project has helped support behaviour change. We draw on both quantitative and qualitative. Study 1 examines quantitative data from the experimental and a matched control group. Study 2 reports qualitative findings from a follow up interview study with participants of the experimental group. As expected, we found significant changes in reported pro-environmental behaviour and identity in the experimental group as well as some indications of behavioural spillover. These changes were not significantly associated with changes in environmental identity. The interviews suggested that group dynamics played an important role in facilitating a sense of efficacy and promote sustained behaviour change and spillover. Moreover, the support by a trusted entity was deemed to be of crucial importance. (shrink)

This study examines the effectiveness of the inoculation strategy in countering vaccine-related misinformation among Hong Kong college students. A three-phase between-subject experiment was conducted to compare the persuasive effects of inoculation messages, supportive messages, and no message control. The results show that inoculation messages were superior to supportive messages at generating resistance to misinformation, as evidenced by more positive vaccine attitudes and stronger vaccine intention. Notably, while we expected the inoculation condition would produce more resistance than the control condition, there (...) was little evidence in favor of this prediction. Attitudinal threat and counterarguing moderated the experimental effects; issue involvement and political trust were found to directly predict vaccine attitudes and intention. The findings suggest that future interventions focus on developing preventive mechanisms to counter misinformation and spreading inoculation over the issue is an effective strategy to generate resistance to misinformation. Interventions should be cautious about using health advocacy initiated by governments among populations with low political trust. (shrink)

The Mismeasure of the Self is dedicated to vices that blight many lives. They are the vices of superiority, characteristic of those who feel entitled, superior and who have an inflated opinion of themselves, and those of inferiority, typical of those who are riddled with self-doubt and feel inferior. Arrogance, narcissism, haughtiness, and vanity are among the first group. Self-abasement, fatalism, servility, and timidity exemplify the second. This book shows these traits to be to vices of self-evaluation and describes (...) their pervasive harmful effects in some detail. Even though the influence of these traits extends to any aspect of life, the focus of this book is their damaging impact on the life of the intellect. Tanesini develops and defends a view of these vices that puts vicious motivations at their core. The analyses developed in this work build on empirical research in attitude psychology and on philosophical theories in virtue ethics and epistemology. The book concludes with a positive proposal for weakening vice and promoting virtue. (shrink)

Berger (2019) argues effectively that “representativeness is more aptly understood as a variable that is multidimensional and continuous based on relational moral authority,” and also makes some useful suggestions about how taking this observation seriously might require changes in current patterns of practice regarding surrogates. But the essay raises additional important questions about how the Best Interest Standard (BIS) should be used among unrepresented patients and other patients as well because many surrogates besides those who “have no actionable knowledge of (...) a patient’s preferences” find themselves in positions in which they need to determine, with the physician, what is in the patient’s best interests. In this commentary, we therefore provide support for the ethical superiority of BIS judgments made by a multi-stakeholder process (rather than solo decision-makers), and sketch a process by which such judgments might be made.

People seem to differ in their visual search performance involving emotionally expressive faces when these expressions are seen on faces of others close to their age compared to faces of non-peers, known as the own-age bias. This study sought to compare search advantages in angry and happy faces detected on faces of adults and children on a pool of children and adults. The goals of this study were to examine the developmental trajectory of expression recognition and examine the development of (...) an OAB. Participants were asked to find a target face displaying an emotional expression among eight neutral faces. Results showed that children and adults found happy faces significantly faster than angry and fearful faces regardless of it being present on the faces of peers or non-peers. Adults responded faster to the faces of peers regardless of the expression. Furthermore, while children detected angry faces significantly faster compared to fearful ones, we found no such difference in adults. In contrast, adults detected all expressions significantly faster when they appeared on the faces of other adults compared to the faces of children. In sum, we found evidence for development in detecting facial expressions and also an age-dependent increase in OAB. We suggest that the happy face could have an advantage in visual processing due to its importance in social situations and its overall higher frequency compared to other emotional expressions. Although we only found some evidence on the OAB, using peer or non-peer faces should be a theoretical consideration of future research because the same emotion displayed on non-peers’ compared to peers’ faces may have different implications and meanings to the perceiver.

In this paper, I investigate the relation of Kant's theory of biology to epigenetic accounts of organic generation and development. In the literature, a dispute about similarities between Blumenbach's epigenetic account and Kant dominated the debate for many years (see Lenoir 1980, 1981, and 1982, 17–34, Richards 2000; 2002, 207–37; Look 2006, and van den Berg 2009). Some more recent interpreters claim that Wolff's, more than Blumenbach's account plays the pivotal role in the development of a vitalistic conception of epigenesis (...) in Kant (see Dupont 2007 and Huneman 2007). Although I myself hold the view that Kant's position contains preformistic and epigenetic characteristics, in the current paper I focus solely on an investigation of epigenetic elements in Kant's account and compare them to the corresponding epigenetic elements in Wolff's theory. Section I of the paper is devoted to an analysis of Wolff's most important epigenetic theorems: the notion of the essential power (vis essentialis) and the conception of the part-whole composition of organized matter. Although Wolff describes the essential power vitalisticly, as a principle of life, he understands it as the cause of mechanical motions explaining the generation, nourishment, and the growth of an organism. Wolff's model of the part-whole composition of organic matter is subtle, but committed to fundamental mechanistic assumptions, such as that the organism as a whole is composed of inorganic parts. In section II, I analyze the corresponding elements in Kant's theory: the notion of the formative power and the conception of the whole-part composition of organized materials. Kant describes the formative power as a principle that causes the purposive form of an organized being such that matter and mechanism are the means to the purpose of the being as their end. The purpose of the whole is a functional unit which is in principle superior to the form and matter of the subordinate parts. The parts are combined into such a whole in being mutually cause and effect of each other and in being related to the superior whole. In section III, I respond to the debate in the literature. Against Dupont (2007) and Huneman (2007) I argue that, according to Wolff, the vis essentialis accounts for mechanic effects in matter, whereas, according to Kant, the formative power explains the intentional order (form, end, purpose) of an individual organized being, its parts, and its species. Since this view is closer to Blumenbach than to Wolff, the ongoing comparison between Kant and Blumenbach in the literature is justified. However, the emphasis on the specific part-whole composition that Kant considers to be the determining feature of an organized being can be found only in Wolff and not in Blumenbach—though Wolff and Kant describe it in opposing ways. This increases the systematic importance of Wolff for Kant. Thus, a fresh look on the historical debate is required. (shrink)
