Category learning and change: differences in sensitivity to information that enhances or reduces intercategory distinctions

We examined the amenability of abstractions of categories to new and relevant information. In Experiment 1, Ss formed impressions of 2 sets of numbers by periodically estimating the cumulative means of each set. During the 1st half of the procedure, the 2 means were mathematically stable. During the 2nd half of the procedure, the mean of 1 set was modified and the mean of the other set remained unchanged. We predicted and found that the resultant estimates for the modified category changed more when the mean difference between the 2 categories was enhanced than when it was reduced. Experiment 2 suggested that the accentuation effect results from a 2-stage process of category learning (Stage 1) and category change (Stage 2). Experiment 3 replicated the effect with person categories. The relevance of category accentuation is discussed with respect to the modifiability of social beliefs.     

Anasakti as Interpreted and Practised in the Bhakti Tradition

Anasakti refers to traits like detachment, non-concern for outcome, equanimity in the face of both pleasant and unpleasant circumstances and selfless duty, accompanied with the ability to disengage from the material pleasures to the extent of completely disconnecting from the fruits of ones’ actions. While anasakti could certainly be a desirable goal for every individual, it is far from easy to bring this into practice. This paper discusses how the Hindu philosophy of Tatvavada as followed by Vaishnava Brahmins impacts their world view and helps develop anasakti in facing various crises in everyday life. This paper draws from a larger ethnomethodologically informed ethnography of a Gurukula. During fieldwork that lasted over 18 months, the researcher was able to observe and interview residents in the Gurukula and devotees visiting the place. The themes that came up in in-depth interviews argue that bhakti may provide a concrete anchor to help develop anasakti in the face of traumatic events, contributing to enhancement of their well-being while providing a sense of meaning and purpose in their lives.     

Marriage Counsellors’ Reflections on the Counselling Process in Family Courts in India

Family courts in India were established to facilitate speedy redressal of family disputes, particularly matrimonial issues. Marriage counsellors facilitated dispute resolution based on alternative dispute resolution practices. Counselling was mandated for all couples approaching family courts due to marital discord. At present, there is a lack of literature on the process of counselling followed by marriage counsellors in the family courts. The present study used an exploratory research design to understand marriage counsellors’ perspectives on the process of counselling in family courts. Fifty-six marriage counsellors completed open-ended questionnaires on counselling assessment, goals, interventions and the influence of the presence of children on the couple counselling process. Thematic text analysis of the responses revealed a range of areas that counsellors explored, individual and relational goals that they focused on, as well as the interventions used by marriage counsellors in their work with couples. Findings suggested that there was a lack of uniformity in the counselling approaches used by marriage counsellors. Additionally, marriage counsellors reported not being equipped to address some intrapersonal and interpersonal concerns that emerged in the counselling process, despite identifying them. Based on the findings, the paper recommends the need for a unifying framework for training and practice for marriage counsellors working with couples in family courts to conceptualise couples’ concerns as well as guide their goals and interventions. The paper underscores the need for acknowledging sociocultural influences, reflective practice and client feedback in the process of counselling.     

A Comparison of Homeless Male Veterans in Metropolitan and Micropolitan Areas in Nebraska: A Methodological Caveat

This study explored differences between homeless male veterans in metropolitan and micropolitan cities in Nebraska on sociodemographic, housing, clinical, and psychosocial characteristics as well as health service use. A convenience sample of 151 homeless male veterans (112 metropolitan, 39 micropolitan) were recruited from Veterans Affairs facilities and area shelters in Omaha, Lincoln, Grand Island, and Hastings in Nebraska. Research staff conducted structured interviews with homeless veterans. Results showed that compared to homeless veterans in metropolitans, those in micropolitans were more likely to be White, unmarried, living in transitional settings, and were far more transient but reported greater social support and housing satisfaction. Veterans in micropolitans also reported more medical problems, diagnoses of anxiety and personality disorders, and unexpectedly, were more likely to report using various health services and less travel time for services. Together, these findings suggest access to homeless and health services for veterans in micropolitan areas may be facilitated through Veterans Affairs facilities and community providers that work in close proximity to one another. Many homeless veterans in these areas are transient, making them a difficult population to study and serve. Innovative ways to provide outreach to homeless veterans in micropolitan and more rural areas are needed.     

Gender differences in implicit and explicit personality traits

This article investigates gender differences in implicit and explicit measures of the Big Five traits of personality. In a high-powered study (N = 14,348), we replicated previous research showing that women report higher levels of Agreeableness, Conscientiousness, Extraversion and Neuroticism. For implicit measures, gender differences were much smaller for all, and opposite in sign for Extraversion. Somewhat higher levels of implicit Neuroticism and Agreeableness were observed in women, and somewhat higher levels of implicit Extraversion and Openness were observed in men. There was no gender difference in implicit Conscientiousness. A possible explanation is that explicit self-concepts partly reflect social norms and self-expectations about gender roles, while implicit self-concepts may mostly reflect self-related experiences.     

Effects of Worldview and Mortality Salience in Persuasion Processes

Individual differences in media effects research have yielded a trove of insights into how media content can have varying effects. One such variable is worldview—a philosophy of life that enables a person to make sense of one's experience—but the notion has largely been unexamined in media effects research. A person's worldview can moderate the way a persuasive message is processed—sometimes in the opposite direction of that intended by communicators. Building on the construct of worldview and terror management theory, two experiments (N = 149 and N = 151) examined the question with worldview as a measured variable and mortality salience as a two-level factor. Worldview had a main effect on global evaluations of ads, as participants who tended toward a relativist worldview had lower evaluations of the ads and lower behavioral intentions, while participants who tended toward a positivist worldview had higher evaluations of the ads and higher behavioral intentions. Also, mortality salience was found to moderate participants' worldview, presumably making their worldview more accessible to exert a greater influence. The importance of worldview as a construct in media effects research, as well as theoretical implications for persuasion and terror management theory, are discussed.     

Mixing virtue and vice: combining the immediacy effect and the diversification heuristic

Many of the most significant choices that people make are between vices, which exchange small immediate rewards for large delayed costs, and virtues, which exchange small immediate costs for large delayed rewards. We investigate the consequences of making a series of such choices either simultaneously or sequentially. We made two predictions. First, because many alternatives chosen under simultaneous choice will only be experienced following a delay, and because hyperbolic time discounting predicts that people will prefer delayed virtues but immediate vices, we predicted that people would choose more virtues in simultaneous than sequential choice. Second, due to the tendency to diversify portfolios of choices, we predicted a greater mix of virtues and vices in simultaneous than sequential choice. These predictions were confirmed in two experiments involving real choices; one between ‘highbrow’ and ‘lowbrow’ movies, and the other between ‘instant‐win’ and ‘prize‐draw’ lottery tickets. We conclude by posing the question of whether simultaneous or sequential choice results in decisions that more closely approximate what people ‘really’ want.

What Contributes to College Students’ Cheating? A Study of Individual Factors

To better understand the multiple individual factors that contribute to college cheating, we undertook a multivariate analysis of a national sample of 2,503 college students. Our findings indicated that demographic characteristics (e.g., gender, socioeconomic status, and year in college), character qualities (e.g., lack of self-control, others-oriented life purpose), college experience (e.g., academic preparation, extracurricular activities involvement, and working), and student perceptions and attitudes (e.g., attitude toward academic cheating, perception of faculty’s actions against cheating and cheating environment) are all significantly associated with academic cheating.     

How to see the Burgers vector of a quasicrystal dislocation

Abstract

We derive, in a density-wave framework, the ‘invisibility condition’ for dislocations in quasicrystals. Our results should be essential for a correct analysis of dislocations in these systems, in particular for measuring their six-dimensional Burgers vectors.
