Effects of provocation on emotions and aggression in males

The effects of provocation of emotions and human physical aggression were examined using a competitive reaction time paradigm. Fifty-four males participated in the competitive task with a fictitious opponent. Participants were assigned to two conditions, low-constant provocation and increasing provocation. Aggression was defined as the intensity of electric shocks participants selected for the opponent to receive. Negative emotions (threat, harm) and positive emotions (benefit, challenge) were assessed at four times during the experimental task. The results revealed that both aggressive responding and harm emotions differed as a function of opponent's level of provocation. There was little compelling evidence that emotions served as an important intervening variable in the relationship between provocation and aggression. Aggr.

Achievement orientations from subjective histories of success: Promotion pride versus prevention pride

A new task goal elicits a feeling of pride in individuals with a subjective history of success, and this achievment pride produces anticipatory goal reactions that energize and direct behavior to approach the task goal. By distinguishing between promotion pride and prevention pride, the present paper extends this classic model of achievement motivation. Regulatory focus theory (Higgins, 1997 ) distinguishes between a promotion focus on hopes and accomplishments (gains) and a prevention focus on safety and responsibilities (non‐losses). We propose that a subjective history of success with promotion‐related eagerness (promotion pride) orients individuals toward using eagerness means to approach a new task goal, whereas a subjective history of success with prevention‐related vigilance (prevention pride) orients individuals toward using vigilance means to approach a new task goal. Studies 1–3 tested this proposal by examining the relations between a new measure of participants' subjective histories of promotion success and prevention success (the Regulatory Focus Questionnaire (RFQ)) and their achievement strategies in different tasks. Study 4 examined the relation between participants' RFQ responses and their reported frequency of feeling eager or vigilant in past task engagements. Study 5 used an experimental priming technique to make participants temporarily experience either a subjective history of promotion success or a subjective history of prevention success. For both chronic and situationally induced achievement pride, these studies found that when approaching task goals individuals with promotion pride use eagerness means whereas individuals with prevention pride use vigilance means.

A Comparison of the 1988 and 1994 Diagnostic Criteria for Chronic Fatigue Syndrome

Chronic Fatigue Syndrome (CFS) is an illness that involves severe, prolonged fatigue as well as neurological, immunological, and endocrinological system pathology. Because the pathogenesis of CFS has yet to be determined, case definitions have relied on clinical observation in classifying signs and symptoms for diagnosis. In an attempt to address various criticisms and inconsistencies in diagnostic criteria, there have been several revisions of the CFS case definition. The current investigation examined the differences between 1988 and 1994 definitions as well as participants who had a psychiatric explanation for their fatigue. Dependent measures included psychiatric comorbidity, symptom frequency, and functional impairment. The 1988 criteria, compared to the 1994 criteria, appeared to select a group of participants with more symptomatology and functional impairment, but these groups did not significantly differ in psychiatric comorbidity. Implications of these findings are discussed.     

Effects of positive youth development programs on school, family, and community systems

A review of efforts at social system change in 526 universal competence-promotion outcome studies indicated that 64% of the interventions attempted some type of microsystemic or mesosystemic change involving schools, families, or community-based organizations in an attempt to foster developmental competencies in children and adolescents. Only 24% of the reports provided quantitative data on the change that occurred in targeted systems. However, studies containing the necessary information produced several mean effect sizes that were statistically significant, and ranged from modest to large in magnitude. These data indicate that attempts to change social systems affecting children and adolescents can be successful. Future work should measure more thoroughly the extent to which the systemic changes that are targeted through intervention are achieved, and investigate how such changes contribute to the development and sustainability of the outcomes that might be demonstrated by participants of competence-promotion programs.

Does self-affirmation, cognitive processing, or discovery of meaning explain cancer-related health benefits of expressive writing?

Although expressive writing has positive effects on health, little is known about the underlying psychological mechanisms for these effects. The present study assessed self-affirmation, cognitive processing, and discovery of meaning as potential mediators of the effects of expressive writing on physical health in early-stage breast cancer survivors. A content analysis of the essays showed that self-affirmation writing was associated with fewer physical symptoms at a 3-month follow-up assessment, with self-affirmation writing fully mediating the effects of the emotional expression and benefit-finding writing conditions on reduced physical symptoms. Cognitive processing and discovery of meaning writing were not associated with any physical health outcomes. Consistent with evidence showing that self-affirmation plays an important role in buffering stress, the present study provides the first evidence for self-affirmation as a viable mechanism underlying the health benefits of expressive writing.     

Attachment and trait forgivingness: The mediating role of angry rumination

Integrating theories of attachment and forgiveness, we predicted that secure attachment reduces angry rumination and promotes forgiveness. To examine this prediction, in Study 1 (n = 213), participants completed the Experience in Close Relationships Scale (ECR; Brennan, Clark, & Shaver, 1998) and the Trait Forgiveness Scale (TFS; Berry, Worthington, O’Connor, Parrott, & Wade, 2005). Individuals who were classified as securely attached displayed greater dispositional forgivingness than did insecurely attached individuals. In Study 2 (n = 218) we included the Dissipation-Rumination Scale (DRS; Caprara, 1986). Results from Study 2 replicated the association between attachment security and greater dispositional forgivingness and confirmed the mediating role of angry rumination in the attachment–forgivingness relation.     

Aging and the depth of binocular rivalry suppression

Two experiments were designed to examine the effect of aging on the strength of binocular rivalry suppression. To produce rivalry, orthogonally oriented sine-wave luminance gratings were presented dichoptically. The observers were then required either to discriminate the spatial location of a probe spot presented to the dominant or suppressed eye's view or to detect the presence or absence of the probe. The observers in the younger and older age groups exhibited typical rivalry suppression for both tasks (i.e., the probe was more difficult to detect or discriminate when presented to the suppressed eye), but the magnitude of the suppression was significantly larger in the older observers. This increased suppression that accompanies aging can be explained by a reduction in the inhibition produced by the binocular matching circuitry of S. R. Lehky and R. Blake's (1991) model.     

Cultural differences in the impact of social support on psychological and biological stress responses

Social support is believed to be a universally valuable resource for combating stress, yet Asians and Asian Americans report that social support is not helpful to them, resist seeking it, and are underrepresented among recipients of supportive services. We distinguish between explicit social support (seeking and using advice and emotional solace) and implicit social support (focusing on valued social groups) and show that Asians and Asian Americans are psychologically and biologically benefited more by implicit social support than by explicit social support; the reverse is true for European Americans. Our discussion focuses on cultural differences in the construal of relationships and their implications for social support and delivery of support services.     

A taxometric analysis of the Psychopathy Checklist: Screening Version (PCL:SV): further evidence of dimensionality

A taxometric analysis of the Psychopathy Checklist: Screening Version (PCL:SV; S. D. Hart, D. N. Cox, & R. D. Hare, 1995) was performed on a group of 2,250 male and female forensic/psychiatric patients and jail/prison inmates. The 4 PCL:SV facet scores (Interpersonal, Affective, Impulsive Lifestyle, Antisocial Behavior) served as indicators in this study, and the data were analyzed with 3 principal taxometric procedures--mean above minus below a cut, maximum eigenvalue, and latent mode factor analysis. The results show evidence of dimensional structure on the PCL:SV in the full sample as well as in all 8 subsamples (men, women, Whites, Blacks, hospital patients, jail/prison inmates, file review with an interview, file review without an interview). These findings corroborate recent taxometric research on the Psychopathy Checklist-Revised (R. D. Hare, 1991, 2003) in which results have been largely dimensional in nature. It is concluded that scores on the PCL:SV differ quantitatively as points on a dimension (high vs. low psychopathy) rather than partitioning into qualitatively distinct categories of behavior (psychopath vs. nonpsychopath).
