The present studies examined whether implied tactile properties during language comprehension influence subsequent direct tactile perception, and the specificity of any such effects. Participants read sentences that implicitly conveyed information regarding tactile properties (e.g., Grace tried on a pair of thick corduroy pants while shopping) that were either related or unrelated to fabrics and varied in implied texture (smooth, medium, rough). After reading each sentence, participants then performed an unrelated rating task during which they felt and rated the texture of (...) a presented fabric. Results demonstrated that the texture properties implied in sentences influence direct tactile perception. Specifically, after reading about a smooth or rough texture, subsequent fabric ratings became notably smoother or rougher, respectively. However, we also show that there was some specificity to these effects: Fabric-related sentences elicited more specific and interactive effects on subsequent ratings. Together, we demonstrate that under certain circumstances, language comprehension can prime tactile representations and affect direct tactile perception. Results are discussed with regard to the nature and scope of multimodal mental simulation during reading. (shrink)

Recent feminist literature has begun to call attention to the diverse linkages between work and family, including the extensive work married women often do for their husbands' careers. Using a longitudinal sample of American women born around 1910, this study employs quantitative and qualitative data to compare different aspects of wives' support and to develop an understanding of how women of their generation constructed their involvement. The authors begin their analysis by comparing wives' support across husbands' occupations and then examining (...) differences in activities and the ways in which women describe their relationships to their husbands' work. They find considerable variation in the way women constructed their relationships to husbands' careers. The evidence suggests that women who provided services directly related to their husbands' work may have been the most satisfied with their involvement. (shrink)

Video games are ideal platforms for the study of skill acquisition for a variety of reasons. However, our understanding of the development of skill and the cognitive representations that support skilled performance can be limited by a focus on game scores. We present an alternative approach to the study of skill acquisition in video games based on the tools of the Expert Performance Approach. Our investigation was motivated by a detailed analysis of the behaviors responsible for the superior performance of (...) one of the highest scoring players of the video game Space Fortress. This analysis revealed how certain behaviors contributed to his exceptional performance. In this study, we recruited a participant for a similar training regimen, but we collected concurrent and retrospective verbal protocol data throughout training. Protocol analysis revealed insights into strategies, errors, mental representations, and shifting game priorities. We argue that these insights into the developing representations that guided skilled performance could only easily have been derived from the tools of the Expert Performance Approach. We propose that the described approach could be applied to understand performance and skill acquisition in many different video games and help reveal mechanisms of transfer from gameplay to other measures of laboratory and real-world performance.

This study furthers scholarship on the religion-entrepreneurship link by proposing that aspects of a country’s religious profile impact individual entrepreneurial activity differently and that a country’s level of investments in knowledge serves as a contingency factor in this milieu. Our cross-level analyses of data from 9,266 individuals and 27 predominantly Christian countries support the second, but not the first suggestion. The study contributes to a more nuanced understanding of religion’s role for entrepreneurship and bridges the literatures on religion and knowledge-based (...) entrepreneurship. Furthermore, the study provides evidence of the effects of religion above and beyond the effects of national culture. (shrink)

Fundamental aspects of human use of the environment can be explained by game theory. Game theory explains aggregate behaviour of the human species driven by perceived costs and benefits. In the 'game' of global environmental protection and conservation, the stakes are the living conditions of all species including the human race, and the playing field is our planet. The question is can we control humanity's hitherto endless appetite for resources before we irreparably harm the global ecosystem and cause extinction of (...) even more species? The central problem is that some proportion of the individuals or groups will behave selfishly. The inducement for using more than a fair share, or 'cheating', increases as that resource becomes rarer, thus the benefits of cheating increase. In addition, the total number of people is increasing, so the proportion of cheaters must decrease to even keep total resource use constant. Cost benefit analysis of the effect of regulation and incentives on potential cheaters may provide a rational approach to controlling environmental problems. While it is debatable that environmental values are constant across cultures, communal use of resources seems to follow global rules. Cooperative use and punishment of those who use more than their share appear to be ubiquitous in human societies. Schemes for controlling human impact on the global environment must take into consideration basic behaviours including development of social norms and the positive feedback created because resources become more valuable with increasing rarity leading to more incentive for consumption.

One of six commentaries on “Obesity: Chasing an Elusive Epidemic,” by Daniel Callahan, from the January‐February 2013 issue.

Background: The American Medical Association, the British Medical Association and the Canadian Medical Association have guidelines that specifically discourage physicians from self-prescribing or prescribing to family members, but only the BMA addresses informal prescription requests between colleagues. Objective: To examine the practices of paediatric providers regarding self-prescribing, curbsiding colleagues, and prescribing and refusing to prescribe to friends and family. Methods: 1086 paediatricians listed from the American Academy of Paediatrics 2007 web-based directory were surveyed. Results: 44% of eligible survey respondents returned (...) usable surveys. Almost half of respondents had prescribed for themselves. An equal number had informally requested a prescription from a colleague. Three-quarters stated they had been asked to prescribe a prescription drug for a first-degree or second-degree relative, and 51% had been asked by their spouse. Eighty-six per cent stated that they had refused to write a prescription on at least one occasion for a friend or family member. The following reasons “strongly influenced” their decision to refuse a prescription request: outside of provider’s expertise ; patient’s need for his or her own physician ; not medically indicated ; need for a physical examination. Conclusion: These data confirm that most physicians have engaged in self-prescribing or curbside requests for prescriptions. It can be argued that curbsiding is more morally problematic than self-prescribing because it implicates a third party, and should be discouraged regardless of whether the requester is a colleague, family member or friend.

The Common Health problems that plague Americans today are often the result of people’s choices and behaviors: obesity, cigarette smoking, accidental pediatric head trauma owing to failure to properly restrain children, and failure to adhere to medication regimens. For each problem, there is a well-studied effective behavioral intervention: a healthy diet and exercise for obesity, smoking cessation programs to overcome cigarette addiction, appropriate car restraints to prevent accidental head trauma, and direct observation of treatment and simplification of medical regimens to (...) improve drug adherence. Traditionally, the physician defined the problem and told the patient what she needed to do. In the modern era of .. (shrink)

This commentary on “Her Own Decision: Impairment and Authenticity in Adolescence” by Campbell, Derrington, Hester, and Lew adds further consideration of obligations for guardians and physicians of minors who struggle in making serious decisions regarding medical treatment.

The so-called Disability Paradox arises from the apparent tension between the popular view that disability leads to low well-being and the relatively high life-satisfaction reports of disabled people. Our aim in this essay is to make some progress toward dissolving this alleged paradox by exploring the relationship between disability and various “goods of life”—that is, components of a life that typically make a person’s life go better for her. We focus on four widely recognized goods of life (happiness, rewarding relationships, (...) knowledge, achievement) and four common types of disability (sensory, mobility, intellectual, and social) and systematically examine the extent to which the four disability types are in principle compatible with obtaining the four goods of life. Our findings suggest that that there is a high degree of compatibility. This undermines the widespread view that disabilities, by their very nature, substantially limit a person’s ability to access the goods of life, and it provides some guidance on how to dissolve the Disability Paradox.

This book provides practical and research-based chapters that offer greater clarity about the particular kinds of teacher reflection that matter and avoids talking about teacher reflection generically, which implies that all kinds of reflection are of equal value.

The c‐ros, c‐met and c‐neu genes encode receptor‐type tyrosine kinases and were originally identified because of their oncogenic potential. However, recent progress in the analysis of these receptors and their respective ligands indicate that they do not mediate exclusively mitogenic signals. Rather, they can induce cell movement, differentiation or morphogenesis of epithelial cells in culture. Interestingly, the discussed receptors are expressed in embryonal epithelia, whereas direct and indirect evidence shows that the corresponding ligands are produced in mesenchymal cells. In development, (...) signals given by mesenchymal cells are major driving forces for differentiation and morphogenesis of epithelia; embryonal epithelia are generally unable to differentiate without the appropriate mesenchymal factors. The observed activities of these receptor/ligand systems in cultured cells and their expression patterns indicate that they regulate epithelial differentiation and morphogenesis also during embryogenesis and suggest thus a molecular basis for mesenchymal epithelial interactions.

Impostor syndrome or Impostor phenomenon is a belief that a person thinks their success is due to luck or external factors, not their abilities. This psychological trait is present in certain groups like women. In this paper, we propose a neutrosophic trait measure to represent the psychological concept of the trait-anti trait using refined neutrosophic sets. This study analysed a group of 200 undergraduate students for impostor syndrome, perfectionism, introversion and self-esteem: after the COVID pandemic break in 2021. Data labelling (...) was carried out using these neutrosophic trait measures. Machine learning models like Support Vector Machine(SVM), K-nearest neighbour (K-NN), and random forest were used to model the data; SVM provided the best accuracy of 92.15%. (shrink)

Clinical trials of xenotransplantation may begin early in the next decade, with kidneys from genetically modified pigs transplanted into adult humans. If successful, transplanting pig hearts into children with advanced heart failure may be the next step. Typically, clinical trials have a specified end date, and participants are aware of the amount of time they will be in the study. This is not so with XTx. The current ethical consensus is that XTx recipients must consent to lifelong monitoring. While this (...) presents challenges to the right to withdraw in the adult population, additional and unanswered questions also linger in the paediatric population. In paediatric XTx, parents or guardians consent not only to the initial treatment of the child but also to lifelong monitoring, thus making a decision whose consequences will remain present as the child develops the capacity for assent, and finally the capacity for informed consent or refusal. This article presents and evaluates unanswered paediatric ethical questions in regard to the right to withdraw from XTx follow-up in the paediatric population. (shrink)

Psychopathy is a disorder characterized by severe and frequent moral violations in multiple domains of life. Numerous studies have shown psychopathy-related limbic brain abnormalities during moral processing; however, these studies only examined negatively valenced moral stimuli. Here, we aimed to replicate prior psychopathy research on negative moral judgments and to extend this work by examining psychopathy-related abnormalities in the processing of controversial moral stimuli and positive moral processing. Incarcerated adult males (N = 245) completed a functional magnetic resonance imaging protocol (...) on a mobile imaging system stationed at the prison. Psychopathy was assessed using the Hare Psychopathy Checklist–Revised (PCL-R). Participants were then shown words describing three types of moral stimuli: wrong (e.g., stealing), not wrong (e.g., charity), and controversial (e.g., euthanasia). Participants rated each stimulus as either wrong or not wrong. PCL-R total scores were correlated with not wrong behavioral responses to wrong moral stimuli, and were inversely related to hemodynamic activity in the anterior cingulate cortex in the contrast of wrong > not wrong. In the controversial > noncontroversial comparison, psychopathy was inversely associated with activity in the temporal parietal junction and dorsolateral prefrontal cortex. These results indicate that psychopathy-related abnormalities are observed during the processing of complex, negative, and positive moral stimuli. (shrink)
