Toward a rodent model of the Iowa gambling task

The Iowa gambling task in humans is, in principle, suited for the study of the long-term efficiency of behavior in a biologically relevant context. Key features of this task are uncertainty of outcomes and a conflict between the immediate and the long-term payoff options. Animal models allow us to study the underlying neurobiology of decision-making processes and the long-term efficiency of behavior in more detail and at a greater depth than is possible in humans. Therefore, we set out to develop a model of this task in rodents, using the task’s key features. In this article, we describe the results of the first series of experiments with rats and mice. The data thus far suggest that mice and rats behave in a way similar to humans; that is, they tend to choose the option with the best long-term payoff more often as the test progresses.     

Strategic self-marginalization: the case of psychoanalysis

Marginality is an important concept in the history of science, though it is often used in a manner that presumes marginality to be a static designation. We contend that the dynamics of marginality are crucial to the history of psychoanalysis, a discipline that has moved between dominant and marginal positions. We address psychoanalytic marginality via three specific "cases": the marginalization among Freud and his followers when psychoanalysis was an emergent discipline; the marginality trope in Erich Fromm's popular psychoanalytic writing when psychoanalysis was orthodoxy in American academic psychiatry; and the rhetorical marginality of psychoanalysis in Sweden as psychoanalysis entered a decline within psychiatry. Our aim is to show that marginalization and self-marginalization serve interpersonal, social, and professional strategies.     

Morality in Groups: On the Social‐Regulatory Functions of Right and Wrong

Applying what we know about group‐based identities and concerns allows us to improve our understanding of the ways in which morality is relevant to social judgments of right and wrong. We distinguish between three different social functions of moral standards and moral judgments. The identity defining function of morality indicates where people want to belong, and how they are regarded by others. The group dynamic function indicates consensual definitions of what is right and wrong that guide individual behavioral choices. The intergroup relations function of group morality, speaks to the way people tend to communicate with and behave towards members of other groups that have different moral standards.     

HIV‐related stigma in social interactions: Approach and avoidance behaviour in a virtual environment

People living with HIV are a stigmatized group in our society, especially homosexual people living with HIV. One of the behavioural manifestations of stigmatization is an increased interpersonal distance kept during social interactions. Immersive virtual environment technology enables the experimental study of social interactions in an accurate and relatively unobtrusive manner. Using a virtual hospital room, we measured to what extent diagnosis (HIV, cancer or broken leg) and sexual orientation (homosexual or heterosexual) were related to approach behaviour (based on the interpersonal distance and the speed of approach), and the degree patients were looked at (as was obtained from an additional exploration of our head orientation data). Moreover, implicit and explicit attitudes were predicted to moderate this relationship. Participants (N = 50) were healthy, heterosexual students. A main effect of diagnosis revealed larger interpersonal distances from patients with HIV than from patients with cancer. Also, an interaction effect demonstrated that distances were largest when the HIV patient was homosexual. Furthermore, a main effect of diagnosis showed that HIV and cancer patients were approached more slowly than broken leg patients, an effect that was larger for HIV than for cancer patients. In addition, head orientation analyses revealed that patients with HIV were relatively ‘looked at’ more often as well as relatively ‘looked away from’ less often than patients with cancer and patients with a broken leg. None of these effects however were found to be moderated by implicit and explicit attitudes. These findings provide behavioural evidence for the stigmatization of people living with HIV and homosexuals with HIV in particular. Copyright © 2015 John Wiley & Sons, Ltd.     

Voice and Culture: A Prospect Theory Approach

The present study examines the congruence of individuals' minimum preferred amounts of voice with the prospect theory value function across nine countries. Accounting for previously ignored minimum preferred amounts of voice and actual voice amounts integral to testing the steepness of gain and loss functions explicated in prospect theory, we use curve fitting to show that ratings of procedural justice fit prospect theory's value function specifically. Further, we investigate the form of this function across nine countries that range in power distance. Results suggest that the form of the value function is congruent with prospect theory, showing an S‐shaped curve that is steeper in the loss than in the gain domain. Further, this pattern is similar across countries. Theoretical and practical implications of these results for both decision making and organizational justice are discussed.

Making Sense of Life: The Existential Self Trying to Deal with Personal Uncertainty

This article is about how people make sense of life and focuses on one core threat that may play a pivotal role in people's lives as existential meaning makers: personal uncertainty. Personal uncertainty is defined as the aversive feeling that you experience when you feel uncertain about yourself. Drawing on an uncertainty management perspective, it is hypothesized that cultural worldviews may provide a means to cope with personal uncertainty and that this may explain why under conditions of personal uncertainty people may respond especially positively to events that bolster their cultural norms and values and particularly negatively to persons and events that violate these norms and values. Findings are reviewed that support the uncertainty management model's predictions. Furthermore, the uncertainty management model may explain why terror management theory is not always about terror, but (at least partly) about personal uncertainty. Finally, conceptual implications, conflicting findings, and loose ends are noted, and testable hypotheses are formulated, which may further insight into the psychological processes pertaining to sense-making, worldview defense, and self-regulation.     

On the Psychology of the Uncertain Self and the Integration of the Worldview Defense Zoo

In this paper, I focus on two issues raised against the uncertainty management model that I proposed. The first issue has to do with the need for deeper insight into psychological processes instigated by uncertainty concerns, including the possibility of positive responses to uncertainty. The second issue revolves around the question to what extent uncertainty management is the core motive (vs. a core motive) of worldview defense and sense-making. By discussing these two issues, I hope to (a) make my view on uncertainty management processes clearer, (b) note explicitly that I was advocating a core motive of worldview defense (not the core motive), and (c) propose a research agenda for future research. I end the article with a plea for research studies that focus on moderators of worldview defense motives. These moderator studies may help to integrate the large variety of core motives proposed in the literature to underlie worldview defense strategies.     

Emoticons in computer-mediated communication: social motives and social context.

This study investigated the role of emoticons in computer-mediated communication (CMC). The study consisted of an online questionnaire about the social motives for emoticon use and an experimental part in which participants (N = 1,251) had to respond to short Internet chats. In these chats, the interaction partner (friend vs. stranger) and the valence of the context (positive vs. negative) were manipulated. Results showed that emoticons are mostly used to express emotion, to strengthen a message, and to express humor. Furthermore, more emoticons were used in communication with friends than in communication with strangers, and more emoticons were used in a positive context than in a negative context. Participants seem to use emoticons in a way similar to facial behavior in face-to-face communication with respect to social context and interaction partner.     

Same-sex attraction, social relationships, psychosocial functioning, and school performance in early adolescence

The authors examined whether 13- to 15-year-old adolescents who experience feelings of same-sex attraction (SSA) differ from those without such feelings in the quality of relationships with parents, peers, and class mentors and in psychosocial functioning (health status and school performance). The authors also assessed whether differences in psychosocial functioning resulted from differences in the quality of social relationships. Data were collected from 866 Dutch high school students (mean age 13.61 years) by means of a computer-based questionnaire. Of the participants, 74 (8.5%) reported having feelings of SSA. The participants with SSA rated the quality of their relationships with their fathers and their peers lower than did those without SSA. Participants with SSA also had poorer mental health (higher levels of depression and lower levels of self-esteem) and lower school performance. A mediation analysis revealed that differences in psychosocial functioning resulted from differences in the quality of the same-sex attracted youths' social relationships, especially with fathers and peers.
