Calculus GPA and Math Identification as Moderators of Stereotype Threat in Highly Persistent Women

The present research tested whether the effect of stereotype threat on calculus performance was moderated by calculus GPA and math identification in advanced undergraduate women majoring in science, technology, and engineering (STEM) fields. Women (n = 102) were randomly assigned to one of three conditions—stereotype threat, gender equivalence, or no mention (of gender). Confirming stereotype threat theory, at high levels of calculus GPA and math identification, women performed the worst in the stereotype threat condition, intermediate in the gender equivalence condition, and best in the no mention condition. Strategies to counter the inimical effects of stereotype threat are discussed     

The Road Not Taken: Fostering Research on the Psychology of Religiosity and Spirituality via Underused Representative,Open-Access Datasets (ROADs)

Psychologists studying religiosity and spirituality (R/S) often face several challenges when conducting their research, such as collecting data from nationally representative samples, cross-cultural generalizability, statistical power, and integrated multilevel approaches. We examined one potential solution—the use of Representative, Open-Access Datasets (ROADs), which are currently underutilized. In this article, we define ROADs; discuss affordances, obstacles, and best practices in using them; document the R/S variables available in various waves of ongoing ROADs collection efforts; and delineate ways to increase usage of ROADs as a research tool in the future. This will enhance the capability of psychologists to address theory-driven questions and to better understand the role of R/S in everyday life, including social attitudes, health, and well-being, as well as social change, cohesion, and conflict. Looking forward, we recommend (a) adding more, and more nuanced, variables to future ROADs data collection efforts; (b) publishing more frequently using ROADs data; and (c) conducting workshops to promote the use of ROADs and to train researchers in secondary data analysis techniques.     

Expanding the Mediational Model of the Effects of Health-Related Social Control

Tucker, Orlando, Elliott, and Klein (2006 ) proposed that the associations between social control attempts and health behaviors are mediated by affects. The evidence is mixed regarding whether affects fully mediate these associations. In a sample of 317 college students involved in heterosexual dating relationships, we tested Tucker's mediational model and an expanded mediational model that incorporated the action readiness component of emotions (motivation to change and reactance). Full mediation of the associations between (a) positive social control and health behavior change; and (b) negative social control and hiding unhealthy behavior were found only when motivation to change and reactance were included in the model. Unexpectedly, reactance and negative social control exerted direct effects on health behavior change.     

A Comparison of the Influence of Conflictual and Supportive Social Interactions on Psychological Distress

Following a quantitative review examining the relative influence of positive and negative social exchanges on emotional health, a second-order factor model of negative social exchange was tested and supported in a sample of 906 college students. Structural equation analysis exploring the unique effects of negative social exchange and perceived support satisfaction on depression revealed both variables to predict this outcome, over and above the contribution of personality and coping variables. In addition to the direct effects of the Big Five personality dimensions on depression, indirect effects of the Big Five via negative social exchange, support satisfaction, and avoidant coping also were observed. Although the prevailing belief among support researchers is that the negative effects of conflictual social interactions outweigh the positive effects of social support, the results of the quantitative review suggest boundary conditions that qualify this conclusion. In addition to corroborating a hierarchical measurement model of negative social exchange, the results of the present investigation suggest that how social support and social negativity are measured substantially influences conclusions concerning their relative impact on psychological distress.     

Lessons learned in deep brain stimulation for movement and neuropsychiatric disorders

The introduction of deep brain stimulation (DBS) as a treatment for medication-refractory essential tremor in the late 1980s revealed, for the first time, that "chronically" implanted brain hardware had the potential to modulate neurologic function with surprisingly low morbidity. Over time, the therapeutic promise of DBS has become evident in Parkinson's disease and dystonia. In some experienced centers, complex tremor disorders, such as posttraumatic Holmes tremor and the tremor of multiple sclerosis, are being increasingly targeted. More recently, other indications, including obsessive-compulsive disorder, Tourette's syndrome, major depression, and chronic pain, have been proposed. As the field has expanded, our knowledge about potential cognitive side effects of DBS has also expanded. This article reviews the current knowledge regarding the impact of stimulation of the subthalamic nucleus, globus pallidus internus, and ventralis intermedius nucleus of the thalamus on symptoms in essential tremor, Parkinson's disease, and dystonia. Also discussed are the emerging targets, what is known about the cognitive sequelae of DBS, and what has been learned about the complications and therapeutic failures.     

The Relations of Dispositional Regulation and Emotionality to Elders' Empathy-Related Responding and Affect While Volunteering

Researchers recently have proposed that various empathy-related reactions are differentially related to individual differences in emotional intensity and regulation. This idea was tested with a sample of elderly hospital volunteers. As predicted, dispositional sympathy was associated with high levels of both dispositional regulation and negative emotional intensity. Personal distress was linked with low regulation and high negative emotional intensity, and cognitive perspective taking was associated with high regulation. Perspective taking moderated the relation of emotional intensity to sympathy and personal distress. In addition, elders' negative affect when volunteering at a hospital was correlated with low regulation and high personal distress. In contrast, positive affect was correlated with high levels of regulation and dispositional sympathy. The results demonstrate that findings pertaining to vicarious emotional responding are generalizable to nonstudent populations engaged in planned, sustained helping behavior.     

Life stress and lymphocyte alterations among patients with rheumatoid arthritis

The relation between life stress and immune parameters was investigated for 33 female rheumatoid arthritis (RA) patients interviewed during three routine monthly clinic checkups. Life stress from major and minor events, coping efficacy, and self-reported psychological distress were assessed, and immunofluorescence of T-cells and B-cells was performed on the blood drawn during each visit. Small stressful events were positively related to the proportion of circulating B-cells, psychological distress was inversely related to proportion of circulating T-cells, and major life events were associated with lower T-helper/T-suppressor cell ratios.     

Social Support,Positive College Events,and College Satisfaction: Evidence for Boosting Effects1

On the basis of previous research on college satisfaction and Cohen and Wills'(1985) social support framework, we hypothesized that structural social support has a main effect on college satisfaction and that the effect of positive college events on college satisfaction is boosted by self-esteem and belonging functional social support. Analyses were based upon a convenience sample of 392 community college students enrolled in psychology courses. Structural social support had a main effect on college satisfaction, and positive college events interacted with self-esteem functional social support. The beneficial effect of positive college events on college satisfaction increased as the level of self-esteem functional social support increased.
