Stress during puberty boosts metabolic activation associated with fear-extinction learning in hippocampus, basal amygdala and cingulate cortex

Adolescence is characterized by major developmental changes that may render the individual vulnerable to stress and the development of psychopathologies in a sex-specific manner. Earlier we reported lower anxiety-like behavior and higher risk-taking and novelty seeking in rats previously exposed to peri-pubertal stress. Here we studied whether peri-pubertal stress affected the acquisition and extinction of fear memories and/or the associated functional engagement of various brain regions, as assessed with 2-deoxyglucose. We showed that while peri-pubertal stress reduced freezing during the acquisition of fear memories (training) in both sexes, it had a sex-specific effect on extinction of these memories. Moreover hippocampus, basal amygdala and cingulate and motor cortices showed higher metabolic rates during extinction in rats exposed to peri-pubertal stress. Interestingly, activation of the infralimbic cortex was negatively correlated with freezing during extinction only in control males, while only males stressed during puberty showed a significant correlation between behavior during extinction and metabolic activation of hippocampus, amygdala and paraventricular nucleus. No correlations between brain activation and behavior during extinction were observed in females (control or stress). These results indicate that exposure to peri-pubertal stress affects behavior and brain metabolism when the individual is exposed to an additional stressful challenge. Some of these effects are sex-specific.     

"Having it all": women's perception of impact of female promotion on threat of domestic violence

This study involved 219 women participants. The main aim of the present study is to examine the perceived consequences of a work-related promotion for the female partner in a heterosexual relationship. The impact of the promotion was manipulated - both partners share paid and domestic work, the male partner taking responsibility for all the domestic work - or female partner continuing to do all the domestic work, as well as the male partner's sexist ideology. Finally, the study examined gender ideology of participants. The results showed that participants felt that violence was more likely when the male partner was presented as sexist and that this was due to a perception of threat on the part of the male partner.     

Validation of a Buddhist Coping Measure Among Primarily Non‐Asian Buddhists in the United States

Researchers have developed scales to measure religious coping among Christians, Jews, Muslims, and Hindus. However, there is no quantitative measure of religious coping for Buddhists. The present study describes the development and initial validation of a scale of Buddhist coping (BCOPE). Eight hundred sixty participants in the United States completed the BCOPE along with demographic information and scales of adjustment to stress. Construct validity of the BCOPE is demonstrated through exploratory and confirmatory factor analyses, which reveals 14 types of Buddhist coping. BCOPE subscales exhibited criterion validity through significant correlations with outcome measures. The BCOPE has incremental validity, predicting adjustment over and above demographic and global religious measures. The research and practical implications of the BCOPE are discussed.     

Feeling and Thinking of Others: Affective and Cognitive Empathy and Emotion Comprehension in Prosocial/Hostile Preschoolers

This study aims at investigating the affective and cognitive components of empathy in relation to both emotion comprehension and prosocial/hostile behaviors in preschoolers. A total of 219 children (54% boys; aged between 3 and 6: mean age 4.10) and 20 teachers (two for each class: group A and group B) took part in this research. Pupils’ empathy and hostile/prosocial roles were assessed by teacher reports [Belacchi and Farina, 2010] and children's emotion comprehension by a nonverbal test [Test of Emotion Comprehension: Pons and Harris, 2000; adapted by Albanese and Molina; 2008]. As expected, the results showed a significant influence of gender, with girls being more empathic than boys, according to all of the teachers’ perception. Contrary to our expectations, no systematic age influence emerged. Regarding the relations of children's emotion comprehension with both empathy measures and their prosocial/hostile attitudes, we have found: (1) a low significant relation with the total empathy measure, according to all the teachers, but with the cognitive empathy only according to teachers B; (2) a robust negative relationship of both affective and cognitive empathy with Hostile roles and with Outsider role, contrary to a positive correlation of only affective empathy with Prosocial roles. No relationships emerged between empathy measures and Victim role.     

Selective exposure in decided and undecided individuals: differential relations to automatic associations and conscious beliefs

People often show a preference for information that confirms their attitudes and beliefs, and this tendency is reduced for opinions that are not held with conviction. The present study shows that both decided and undecided individuals show a tendency to selectively expose themselves to confirmatory information, albeit with different antecedents and consequences. Whereas selective exposure in decided participants was predicted by conscious beliefs and not by automatic associations, selective exposure in undecided participants was predicted by automatic associations and not by conscious beliefs. Moreover, selective exposure led undecided participants to adopt conscious beliefs that were in line with their preexisting automatic associations. Conversely, for decided participants, selective exposure shifted automatic associations in a direction that was in line with their preexisting conscious beliefs. Implications for decision making and mutual influences of automatic associations and conscious beliefs in attitude change are discussed.     

Factor analysis of ipsative data: a simulation study

This paper introduces a summary on how to proceed to conduct a factor analysis when the input data are ipsative. The classical factor analysis procedures cannot be used because the covariance matrix is singular. Additionally, previous research on the optimal conditions to conduct factor analysis for ipsatized data is reviewed, and the results of a simulation study are presented. The study includes conditions of sample size, model complexity, and model specification (correct vs. incorrect). The results suggest that researchers should be careful when factor analyzing ipsatized data, particularly if they suspect that the model is incorrectly specified and includes a smaller number of factors.     

Effects of category label activation about the elderly

The present research focuses on the study of behavioral effects of non-conscious activation of categories among outgroup (young people) and ingroup members (elderly people). Specifically, non-conscious activation of labels that designate the same group, but with different valence (old vs. elderly), showed an effect on a behavior not directly related to interaction with elderly. The first study with young individuals (N= 62) shows that, after non-conscious activation of a negative label (old), participants displayed longer RTs in the first phase of the task than in the case of positive label (elderly) priming. The second study (N= 40), performed with elderly people, shows a similar result, after non-conscious activation of a negative label (old), elderly people showed longer RTs in the first phase of the task, compared with the group in the non-conscious positive label activation condition. Results concerning the theoretical and practical implications are discussed.     

Sociodemographic, clinical and outcome differences among anxiety disorders

The aims of this paper are to analyze differences in sociodemographic and clinical characteristics among the various anxiety disorders treated in a Psychology Clinic, and the results of treatment in each anxiety disorder. Data from 282 patients of University Psychology Clinic at the Complutense University of Madrid, who had at least one diagnosis of anxiety according to DMS-IV-TR criteria, were analyzed. The most frequent anxiety disorders were nonspecific anxiety disorder (19.1%) and social phobia (18.8%). Significant differences were observed according to sex (in all disorders, the percentage of women was significantly higher than that of men, except for obsessive-compulsive disorder). Unspecific anxiety disorder required a smaller number of assessment and treatment sessions, whereas obsessive-compulsive disorder required a greater number of sessions. There were no significant differences between the percentage of patients who completed treatment and dropout rates in specific phobia, general anxiety disorder and obsessive-compulsive disorder. Differences between epidemiological and clinical data are discussed.     

Second-class citizen? Contract workers' perceived status,dual commitment and intent to quit

Outsourcing of jobs to contract workers who work alongside a client's employees has changed the human resource landscape of many organizations. In this study we examine how a contract worker's perceived employment status similarity to the client's own standard employees influences his/her affective commitment to both the client and the employer and ultimately intent to quit the employer. Using a sample of 623 contract workers, we found strong support for our hypotheses. In particular, findings indicate an important role for perceived employment status at the client organization in driving contract worker's attitudes and that contract workers consider both the client and the employer when making decisions to leave the employer. Implications for managing contractor relationships are discussed.
