Examining effects of training duration on humans' resurgence and variability using a novel touchscreen procedure

Resurgence occurs when a previously reinforced and then extinguished target response increases due to reducing/eliminating an alternative source of reinforcement or punishing an alternative response. We evaluated whether duration of reinforcement history for a target response (1) affects the degree to which resurgence is observed in humans and (2) produces different gradients of response generalization around target responding during extinction testing. We arranged a novel touchscreen interface in which university students could swipe a 3D soccer ball to spin any direction. In Phase 1, the first direction swiped became the target and produced points exchangeable for money for 3 or 1 min across 2 groups. The first swipe was recorded but had no programmed consequence in a third group. In Phase 2, swipes 180-degrees from the target resulted in points for 3 min in all groups. Point deliveries ceased for 2 min to test for resurgence in Phase 3. Target responses resurged during testing to a relatively greater extent with longer Phase-1 training but gradients of response generalization did not differ among groups. These findings extend prior research on the role of training duration on resurgence. We discuss methodological and conceptual issues surrounding the assessment of response generalization in resurgence.     

What do tertiary level students in the U.S.A. and Northern Ireland (UK) worry about? An exploratory study

The purpose of this study is to determine the personal and social worries of samples of tertiary-level students in the U.S.A. and Northern Ireland (UK) using the Things I Worry About Scale (TIWAS). An online questionnaire, which included the TIWAS, was completed by two samples (U.S.A.?=?71 and Northern Ireland?=?187). Results indicate that students, in both locations, report worrying frequently about a similar broad range of issues, particularly the challenges of academic study and achievement, financial matters and future career possibilities. The needs of individual students who express frequent worrying about experiences ‘sometimes’ worried about by the majority are noted. The overall findings support perceptions that a majority of students are rather anxious, are under considerable pressure and worry very frequently.     

Using behavioral economics to optimize safer undergraduate late-night transportation

Many universities sponsor student-oriented transit services that could reduce alcohol-induced risks but only if services adequately anticipate and adapt to student needs. Human choice data offer an optimal foundation for planning and executing late-night transit services. In this simulated choice experiment, respondents opted to either (a) wait an escalating delay for a free university-sponsored “safe” option, (b) pay an escalating fee for an on-demand rideshare service, or (c) pick a free, immediately available “unsafe” option (e.g., ride with an alcohol-impaired driver). Behavioral-economic nonlinear models of averaged-choice data describe preference across arrangements. Best-fit metrics indicate adequate sensitivity to contextual factors (i.e., wait time, preceding late-night activity). At short delays, students preferred the free transit option. As delays extend beyond 30 min, most students preferred competing alternatives. These data depict a policy-relevant delay threshold to better safeguard undergraduate student safety.     

Sex-Linked Carrying Styles and the Attribution of Homosexuality

Abstract

We used pairs of slides showing 3 women and 3 men displaying 2 sex-linked carrying styles to examine differences in the attribution of homosexuality as a consequence of behavioral displays that are either sex typical or sex atypical. We hypothesized that the participants would be less likely to view targets displaying sex-typical behaviors as gay men or as lesbians. Each of 2 groups of U.S. university students rated targets in 6 slides on homosexuality and 3 other traits. The mean difference in rated homosexuality for typical versus atypical carrying styles was small but statistically significant. Thus, the results provide some empirical support for the common belief that effeminate men and masculine women are more likely to be seen as homosexual, at least by U.S. university students.     

Motivation for Conflict Among Chinese University Students: Effects of Others' Expertise and One's Own Confidence on Engaging in Conflict

Abstract

Researchers (A. C. Amason, 1996; D. H. Gruenfeld, 1995; K. A. Jehn, 1995, 1997; M. A. Rahim, 1989; M. A. Rahim & A. A. Blum, 1994; D. M. Schweiger, W. R. Sandberg, & P. L. Rechner, 1989; P. E. Tetlock, D. Armor, & R. S. Peterson, 1994) have documented the value of conflictual discussions for solving problems, but few have explored the conditions under which people are motivated to engage in controversy (K. A. Jehn, C. Chadwick, & S. M. B. Thatcher, 1997). Some (M. Van Berklom & D. Tjosvold, 1981) have hypothesized that high expertise and a competitive social context arouse concerns about defending one's position and challenging the opposing one. In the present study, Chinese university students in Hong Kong who expected to disagree with an expert, compared with those who did not expect to disagree with an expert, had less confidence, felt less knowledgeable about their position, and selected an agreeable discussant. Consistent with the idea of maintaining distance from those in power, the participants were reluctant to disagree directly with someone with greater expertise.     

Identity Management Strategies in Northern Ireland

Abstract

Social identity theory suggests that individuals and groups use different identity management strategies to cope with threatened identities. In October 1998, the authors developed 5 identity management strategy scales for use in the changing political context of Northern Ireland and investigated the relationship of perceptions of stability and legitimacy, as well as in-group identification, to those strategies. Participants were 209 students of the University of Ulster and the Belfast Institute. The results supported the factor structure of the identity management strategy scales. Perceptions of stability and legitimacy and in-group identification were, however, correlated with some strategies only. That finding may indicate that some identity management strategies are related to psychological constructs not covered by social identity theory.     

Religious coping,stress, and quality of life of Muslim university students in New Zealand

Most of the research on religious coping has been conducted with Christian participants from Western cultures, although in recent years increasingly more studies have been conducted with Muslim participants. For university students in Muslim countries, religiosity is positively correlated with a variety of indices of mental health and psychological well-being, but only a small number of studies investigated coping in Muslims living and studying in a non-Muslim country. The present study thus explored the relationship between perceived stress, quality of life (QOL), and religious coping in a sample of 114 Muslim university students in New Zealand. International Muslim students had higher levels of spirituality/religiousness than domestic Muslim students, and used more positive and negative religious coping methods. For international students, positive religious coping was positively related to QOL and lack of stress, while, for domestic students, negative religious coping was negatively related to the QOL and increased stress. This different pattern may relate to the ethnic background of the participants, and the results of the present study thus highlight that Muslims studying at universities overseas can certainly not be considered as a homogenous group.

Ethical Conflicts in Commercialization of University Research in the Post–Bayh–Dole Era

Protection of intellectual property as well as its exploitation for monetary benefit have existed for centuries. However, commercialization of intellectual property had not entered the precincts of academic universities in a significant way until the introduction of the Bayh–Dole Act in the 1980s in the United States. The post–Bayh–Dole era has seen a quantitative increase in patenting activity in universities. This article summarizes the ethical conflicts ushered in by increasing commercialization of academic university research. Activities related to the protection and commercial exploitation of intellectual property have led to changes in academic culture that have given room for debate between the puritans and the modernists. Issues contended by the two groups have been identified, and both sides of the argument are discussed. The key to achieving “responsible commercialization of research” is to balance the Bayh–Dole ethos with the traditional Mertonian norms of academic research.
