Cognitive bias and emotion in neuropsychological models of depression

Neuropsychological models of depression were tested by examining encoding and recognition biases elicited by emotional stimuli manifested in regional brain wave activity. Participants were pre-exposed to emotional stimuli. These stimuli were presented again embedded in new stimuli, and event-related brain potentials (ERPs) were recorded while participants judged whether they had viewed each stimulus previously. Controls showed an enhanced P300 during encoding and reduced P300 during recognition of positive stimuli, indicating a response bias for positive information. In contrast, participants diagnosed with major depression showed no valence difference during encoding of new stimuli or recognition of old stimuli. These results suggest positive cognitive biases in controls and a lack of such a biases in depressed individuals. Additionally, regression analyses demonstrated that a substantial proportion of P300 variance was related to clinical scale     

Integrated Behavior Therapy for Selective Mutism: A randomized controlled pilot study

Objective

To evaluate the feasibility, acceptability, and preliminary efficacy of a novel behavioral intervention for reducing symptoms of selective mutism and increasing functional speech.

Method

A total of 21 children ages 4 to 8 with primary selective mutism were randomized to 24 weeks of Integrated Behavior Therapy for Selective Mutism (IBTSM) or a 12-week Waitlist control. Clinical outcomes were assessed using blind independent evaluators, parent-, and teacher-report, and an objective behavioral measure. Treatment recipients completed a three-month follow-up to assess durability of treatment gains.

Results

Data indicated increased functional speaking behavior post-treatment as rated by parents and teachers, with a high rate of treatment responders as rated by blind independent evaluators (75%). Conversely, children in the Waitlist comparison group did not experience significant improvements in speaking behaviors. Children who received IBTSM also demonstrated significant improvements in number of words spoken at school compared to baseline, however, significant group differences did not emerge. Treatment recipients also experienced significant reductions in social anxiety per parent, but not teacher, report. Clinical gains were maintained over 3 month follow-up.

Conclusion

IBTSM appears to be a promising new intervention that is efficacious in increasing functional speaking behaviors, feasible, and acceptable to parents and teachers.     

Effect of pre- and postcompetition emotional state on salivary cortisol in top-ranking wrestlers

The purpose was three-fold: (1) to investigate the effect of baseline, precompetition, and postcompetition stress on salivary cortisol levels in top-ranking Brazilian wrestlers (N = 17) participating in a national competition; (2) to estimate correlations among three stress measures (perceived stress, salivary cortisol, and physiological stress reaction); and (3) to compare cortisol concentrations between losers and winners. Salivary cortisol was collected at baseline, pre-, and postcompetition. Physiological stress reaction and perceived stress scores were measured just before warm-up for the competition. Analysis showed a significant main effect for testing time. Correlations among the stress measures were not significant. Analysis of covariance between the winners (n = 10) and the losers (n = 7) was also not significant. Salivary cortisol concentrations increased after the intense exercise of competition. The wrestlers did not perceive any physiological effects.     

Family background and academic achievement: does self-efficacy mediate outcomes?

Research indicates both family background and self-efficacy influence academic outcomes; however, family background also impacts self-efficacy development. The purpose of the current study was to establish whether self-efficacy mediates the relationship between family background and academic achievement. Results indicated family background features were not robust predictors of academic achievement in the current sample, which limited testable mediation pathways. Evidence was found that self-efficacy does mediate the relationship between parental involvement and expectations of academic success. Results also indicated self-efficacy is a strong and consistent predictor of grade point average and expectations of academic success. Based on these findings, it is recommended educators utilize previously developed classroom strategies which have been shown to enhance students’ self-efficacy levels.     

Resource replacement and psychological well-being during unemployment: The role of family support

There is an established inverse relationship between unemployment and psychological wellbeing. However, little is known about the processes that underlie this relationship. Using latent deprivation, conservation of resources, and social capital to form a theoretical framework, this study explored the relationship between the latent benefits associated with employment, family support, and financial strain. In a sample of 174 unemployed individuals, latent benefits were shown to partially mediate the relationship between family support and psychological well-being. Additionally, this mediation was moderated by financial strain, with latent benefits being more related to psychological well-being in those with greater financial strain. These findings provide guidance in understanding how to better address the needs that contribute to psychological well-being in those who are unemployed.     

Career adaptivity,adaptability, and adapting: A conceptual and empirical investigation

The literature on career adaptation is vast and based on a range of different measurement approaches. The present paper aims to explore how different operationalizations of career adaptability in terms of concern, control, curiosity, and confidence are related from a conceptual and empirical standpoint. Based on a cross-sectional analysis with 1260 German university students, we established that the adaptability resources of concern, control, curiosity, and confidence are significantly related to, but empirically distinct from, measures representing adapting in terms of career planning, career decision-making difficulties, career exploration, and occupational self-efficacy. In a follow-up survey six months later, we found that the career adaptability dimensions partially mediated the effects of adaptivity (i.e., core self-evaluations and proactivity) on planning, decision-making difficulties, exploration, and self-efficacy. Interestingly, in both analyses, there was no clear match between adaptability resources and theoretically corresponding aspects of career adapting in terms of behaviors, beliefs, and barriers. The results suggest that psychological career resources in terms of concern, control, curiosity, and confidence partially mediate the effects of more context-general, trait-like adaptivity on different career-specific behavioral forms of adapting.
