Resurgence of response sequences during extinction in rats shows a primacy effect

Rats were trained to emit a series of three-response sequences to a criterion (i.e., more than 80% of all emitted sequences correct over five successive sessions). Each rat was trained on a series of different, three-response sequences. After the final three-response sequence was acquired, two extinction tests were administered, and the three-response sequences that re-emerged during these extinction tests were noted. Resurgence effects during extinction were observed; that is, the previously trained sequences were emitted. These resurgence effects followed an orderly pattern, which involved a primacy effect. The rats initially emitted the immediately previously trained response, but then started to emit the response sequence they first were trained to emit. Thus, resurgence behavior during extinction can be an orderly function of previous training history. These results replicate those previously obtained with human subjects.     

Depressive Symptomatology among HIV-Positive Women in the Era of HAART: A Stress and Coping Model

Objective: An enhanced stress and coping model was used to explain depression among HIV-positive women in healthcare and community settings where highly active anti-retroviral treatment (HAART) was commonplace. Method: HIV-infected women in four cities (N=978) were assessed, cross-sectionally, for mental and physical health, stress, social support, and other background factors. Results: Self-reported level of depressive symptomatology was high. Number of physical symptoms, illness intrusiveness, and perceived stress were positively associated with depressed mood, while coping self-efficacy and social support were negatively associated. Stress mediated the effect of health status on depression and coping self-efficacy mediated the effect of psychosocial resources on depression. Our enhanced stress and coping model accounted for 52% of variance in depressive symtpomatology. Conclusions: Interventions focused on improving coping self-efficacy, bolstering social supports, and decreasing stress in the lives of HIV-positive women may help to reduce the negative effects of HIV disease on mood.     

How Parents Still Help Emerging Adults Get Their Homework Done: The Role of Self-Regulation as a Mediator in the Relation Between Parent–Child Relationship Quality and School Engagement

Although parents are increasingly involved in their college students’ academic lives, scholars have yet to investigate parents’ role in their college students’ school engagement. We hypothesized that college students’ self-regulation would mediate the relation between parent–child relationship quality and school engagement. For the 790 undergraduates who completed questionnaires online, self-regulation mediated the relation between mother–child relationship quality and school engagement for men, and an indirect effect was found for the relation between father–child relationship quality and school engagement by way of self-regulation. Therefore, parents continue to matter in promoting their college students’ academic success.     

The Tragedy of the Few

In this article I elaborate and defend a rights-based understanding of climate politics, that is, one that takes climate politics to concern the rights to access of natural resources as opposed to people’s economic incentives. The argument contains two parts. The first is negative: to demonstrate that the tragedy of the commons as a story of climate change is inadequate. The second is positive: to suggest a more satisfactory framework, which I call the tragedy of the few. In this view, climate politics is neither primarily mitigation nor economic incentive politics, but one of distributing rights to access natural resources in a fair and environmentally-friendly way. By changing both the narrative and underlying methodological assumptions, my goal is to enable us to accommodate the rights to access natural resources as a key moral issue in climate politics. I begin by sketching the main features of the tragedy of the commons and demonstrate its inadequacy. I then provide an account of the rights-based view of climate change that consists of two arguments. First, I demonstrate the normative side of the argument by highlighting the importance of environmental rights, and second, I outline the empirical side of the argument by discussing recent studies on the properties of natural resources and on the corporate agents who extract the resources that emit greenhouse gasses.     

Response Style Theory Revisited: Gender Differences and Stereotypes in Rumination and Distraction

Response Style Theory [S. Nolen-Hoeksema (1987) “Sex Differences in Unipolar Depression: Evidence and Theory,” Psychological Bulletin, Vol. 101, pp. 259–282] suggests that, when depressed, women ruminate on their sad feelings while men distract themselves from theirs. We sought to examine this gender difference in more detail. In Study 1, 155 students provided stereotype ratings or self-reports of responses to depression. The stereotype ratings conformed precisely to Response Style Theory yet exaggerated self-reported gender differences, especially for men. In Study 2, 40 roommate pairs completed a similar set of ratings. Again, other-ratings conformed exactly to Response Style Theory's predictions while self-ratings showed a more moderated pattern. In both studies, women reported ruminating more than did men, yet men and women were equally likely to report distraction. We conclude by examining several hypotheses for the discrepancies between stereotypes and self-reports for men as well as the increased rates of rumination among women.     

The Impact of Participant Characteristics,Perceived Motives,and Job Behaviors on Co-Workers' Evaluations of Workplace Romances1

Using a policy capturing approach, we examined the importance that observers placed on 7 different factors when evaluating workplace romances. Nearly half the explained variation in observers' evaluations of workplace romances was accounted for by participants' marital status. Participants' organizational status relative to one another was also important in explaining the variation. A series of nomothetic analyses indicated that workplace romance participants' marital status, academic status, motive for entry into the relationship, and job performance affected observers' evaluations of these relationships. Observers' level of prior involvement in a workplace romance was also significantly related to a number of variables. Results suggest that when evaluating workplace romances, observers place the greatest importance on the personal characteristics of participants. Ramifications for policy formation are discussed.     

Men,women, and money: Exploring the role of gender,gender-linkage of college major and career-information sources in salary expectations

Research focused on salary expectations consistently reports gender-based differences in expectations for entry and peak career. Although a number of variables (e.g., value placed on work-facets, fair pay standards) have been found to mediate the relationship between gender and salary expectations, little research has attempted to assess how expectations may be formed. Based on suggestions by Martin (1989) and social comparison theory, we examined the role that sources of career information (e.g., professors, family) play in shaping college students' salary expectations. Results suggest: (1) differences in entry level salary expectations were associated with gender-linkage of college major and differences in peak salary expectations were associated with gender and gender-linkage of college major, (2) women gathered more information from female sources than did men, and men gathered more information from male sources than did women, and (3) career information was not predictive of either entry or peak salary expectations.     

career beliefs and job satisfaction in adults with symptoms of attention‐deficit/hyperactivity disorder

The authors evaluated dysfunctional career beliefs and subsequent low job satisfaction in adults reporting significant symptoms of attention‐deficit/hyperactivity disorder (ADHD). Participants (N= 81) completed the Adult Attention Deficit Disorders Evaluation Scale (S. B. McCarney & P. D. Anderson, 1996), the Career Thoughts Inventory (J. P. Sampson, G.W. Peterson, J. G. Lenz, R. C. Reardon, & D. E. Saunders, 1996), and the Minnesota Satisfaction Questionnaire (D. J. Weiss, R. V. Dawis, G. W. England, & L. H. Lofquist, 1967). Regression analyses confirmed that ADHD symptoms were significantly predictive of dysfunctional career beliefs, decision‐making confusion, commitment anxiety, and external conflict.     

The functional independence of trait self-knowledge: commentary on Sakaki (2007)

In a recent paper, Sakaki (2007) proposed that Klein and Loftus's conclusion that semantic and episodic trait self-knowledge are functionally independent (e.g., Klein, Babey, & Sherman, 1997; Klein & Loftus, 1993a; Klein, Loftus, Trafton, & Fuhrman, 1992b) was based on questionable assumptions and not supported by the available evidence. In this paper we show that Sakaki (2007) has misinterpreted our position on the independence of self-knowledge, omitted mention of large portions of the relevant research at odds with her contention, and conducted her studies with procedures we explicitly warned against due to interpretive ambiguities associated with their use.
