Female meadow voles (Microtus pennsylvanicus) demonstrate same-sex partner preferences

Female meadow voles (Microtus pennsylvanicus) are territorial during warm months but demonstrate social tolerance under low temperatures. In spring, females nest together and some pairs participate in communal nursing and rearing of young. Because communal nursing involves significant cooperation, selective pair-bonds may develop between 2 nestmates. Using a choice apparatus, the authors determined that (a) captive females demonstrated partner preferences for a nestmate; (b) partner preferences were enduring and persisted after dyadic separation; and (c) following the loss of a nestmate, females did not develop preferences for a new nestmate, even after extended cohabitation. Data support the hypothesis that captive meadow voles develop selective and enduring same-sex social bonds that may, under free-living conditions, facilitate communal nesting and cooperative rearing of young.     

Performance and Private Speech of Children with Attention-Deficit/Hyperactivity Disorder While Taking the Tower of Hanoi Test: Effects of Depth of Search,Diagnostic Subtype,and Methylphenidate

We administered the Tower of Hanoi to demographically comparable samples of control participants (n = 34) and children with the Combined (n = 22) and Inattentive subtypes (n = 19) of Attention-Deficit/Hyperactivity Disorder (ADHD). Controls excelled over children with the Inattentive subtype, who outperformed patients with the Combined subtype. These results replicated findings of greater executive deficits in the Combined than in the Inattentive type of ADHD. Double-blind administration of methylphenidate improved task performance only for patients with the Inattentive subtype. In a drug-free Baseline session, children with both subtypes of ADHD made more private verbalizations than controls, particularly when failing puzzles. In later sessions, regardless of drug condition, the inattentive sample exhibited a smaller increase in self-regulatory utterances under failure. In contrast, the combined sample decreased self-regulatory verbalizations under failure only under methylphenidate. The results support some differences between the two subtypes of ADHD in executive functioning and in their response to stimulant therapy. Portions of these results were submitted as part of H. Theresa Chang's PhD dissertation (Chang, 2000) and Helena Kopecky's unpublished master's research, both conducted at the University of Rochester and supervised by Rafael Klorman.     

Emotion Regulation in Workgroups: The Roles of Demographic Diversity and Relational Work Context

Drawing on the social identity perspective, we investigate the cross‐level relationship between demographic diversity in workgroups and emotion regulation. We propose that age, racial, and gender diversity in workgroups relate positively to emotion regulation because of demography‐related in‐group/out‐group dynamics. We also examine the moderating role of the relational work context, specifically task interdependence and social interaction, on the relationship between demographic diversity and emotion regulation. Results from a sample of 2,072 employees in 274 workgroups indicate that working in a group with greater age diversity is positively related to an employee's emotion regulation. Results suggest the operation of the age diversity effect can be attributed primarily to younger employees when they are in workgroups with older coworkers. Results reveal asymmetric effects for racial diversity such that racial out‐group members engage in higher levels of emotion regulation than racial in‐group members when racial diversity is low, whereas racial in‐group members engage in higher levels of emotion regulation than racial out‐group members when racial diversity is high. Race effects also suggest a moderating effect of social interaction; specifically, social interaction weakens the relationship between racial diversity and emotion regulation. Gender effects are not significant.

My funny valentine: How humor styles affect romantic interest

Humor tends to predict romantic attraction, but does the style in which it is communicated matter? This study uses experimental methods to test the effects of positive and negative humor styles on short‐term and long‐term romantic interest. The authors randomly assigned 251 participants to read 1 of 4 relationship initiation vignettes depicting either an affiliative or aggressive humor style. Participants reported their short‐term and long‐term interest and made judgments of the relationship initiator's competence and warmth. Results support a fitness indicator model of humor style's role in relationship initiation; positive styles were preferred for long‐term relationships while competence and warmth inferences predicted long‐term attraction. The findings are discussed within the broader context of mate selection goals and challenges.     

Do gender–science stereotypes predict science identification and science career aspirations among undergraduate science majors?

The present research examined whether gender–science stereotypes were associated with science identification and, in turn, science career aspirations among women and men undergraduate science majors. More than 1,700 students enrolled in introductory science courses completed measures of gender–science stereotypes (implicit associations and endorsement of male superiority in science), science identification, and science career aspirations. Results were consistent with theoretically based predictions. Among women, stronger gender–science stereotypes were associated with weaker science identification and, in turn, weaker science career aspirations. By contrast, among men stronger gender–science stereotypes were associated with stronger science identification and, in turn, stronger science career aspirations, particularly among men who were highly gender identified. These two sets of modest but significant findings can accumulate over large populations and across critical time points within a leaky pipeline to meaningfully contribute to gender disparities in STEM domains.     

Causal attributions for heart disease: A systematic review

Abstract

The aims of this systematic literature review are to describe the pattern of attributions made for the causes of heart disease, and to determine how this pattern varies with the method by which attributions are elicited, and the respondent group.

A search yielded 47 papers and reports, containing 54 datasets. Lifestyle factors and chronic stress were the most common causes cited across all datasets. Attributions to stressors and fate or luck were more likely to be reported in studies that used interval rating scales than in studies that used dichotomous ratings. Cardiac patients were more likely to mention stressors and fate or luck as causes of heart disease; non-patients rated being overweight and hypertensive as more important

The differences observed between the responses of patients and non-patients may be due to actor - observer differences, or to a methodological difference: patients are often asked to report their own experiences whereas non-patients are asked about the general case.     

The work–family interface among school psychologists and related school personnel: a test of role conflict and expansionist theories

The purpose was to test of the utility of role conflict and expansionist theories in explaining the work–family interface using psychometrically sound instruments. Participants (n = 74) responded to measures of work–family conflict, work‐related stress, and role quality. In support of the expansionist theory, results indicated that the quality of the life roles was a better predictor of both work–family conflict and work‐related stress than was the number of life roles. For both, results indicated that as quality of the work role increased, work–family conflict and work‐related stress decreased. The implications for the research on the work–family life interface and attracting and retaining the most qualified school psychologists are discussed.
