Dual-task automatization: The key role of sensory–motor modality compatibility

How do people automatize their dual-task performance through bottleneck bypassing (i.e., accomplish parallel processing of the central stages of two tasks)? In the present work we addressed this question, evaluating the impact of sensory–motor modality compatibility—the similarity in modality between the stimulus and the consequences of the response. We hypothesized that incompatible sensory–motor modalities (e.g., visual–vocal) create conflicts within modality-specific working memory subsystems, and therefore predicted that tasks producing such conflicts would be performed less automatically after practice. To probe for automaticity, we used a transfer psychological refractory period (PRP) procedure: Participants were first trained on a visual task (Exp. 1) or an auditory task (Exp. 2) by itself, which was later presented as Task 2, along with an unpracticed Task 1. The Task 1–Task 2 sensory–motor modality pairings were either compatible (visual–manual and auditory–vocal) or incompatible (visual–vocal and auditory–manual). In both experiments we found converging indicators of bottleneck bypassing (small dual-task interference and a high rate of response reversals) for compatible sensory–motor modalities, but indicators of bottlenecking (large dual-task interference and few response reversals) for incompatible sensory–motor modalities. Relatedly, the proportion of individuals able to bypass the bottleneck was high for compatible modalities but very low for incompatible modalities. We propose that dual-task automatization is within reach when the tasks rely on codes that do not compete within a working memory subsystem.

     

Bouncing Back from Setbacks: On the Mediating Role of Team Resilience in the Relationship Between Transformational Leadership and Team Effectiveness

The purpose of this study was to clarify the role of team resilience on different facets of effectiveness (team viability and quality of the group experience). Moreover, given the importance of team resilience for the organizational context, it was also our aim to contribute to the study of the conditions that promote team resilience, analyzing the role of transformational leadership. Finally, we examined whether the relationship between transformational leadership and team resilience stimulates positive team outcomes. Ninety teams (445 employees from 40 companies) were surveyed and path analysis was used in the test of the hypotheses. The results showed a positive direct effect of team resilience on both team viability and the quality of the group experience. Moreover, a positive relationship was also identified between transformational leadership and team resilience. Finally, support was found for the mediated effect of team resilience on the relationship between transformational leadership and the dimensions of team effectiveness considered. The findings of this study highlight the role of team resilience as an intervening process between transformational leadership and team effectiveness. Supervisors should promote team resilience, adopting transformational leadership behaviors, in order to contribute to increase team viability and the quality of the group experience.     

Self-Criticism,Neediness, and Distress in the Prediction of Suicide Ideation: Results from Cross-Sectional and Longitudinal Studies

The aim of the present study was to test whether the maladaptive personality traits of self-criticism and neediness predict suicide ideation when controlling for general distress. Further, potential interactive effects on suicide ideation of the two traits and distress were also evaluated. Two studies with nonclinical samples were conducted. The first investigation was cross-sectional and involved a final sample of 202 community adults while the second study was longitudinal with a final sample of 207 college students. Results of Study 1 demonstrated that self-criticism, but not neediness, associated with suicide ideation and, in doing so, also interacted with distress. Neediness also tended to interact with self-criticism in the prediction of suicide ideation. Results from Study 2 were similar and confirmed the Study 1 results. Changes in self-criticism, but not changes in neediness, predicted changes in suicide ideation after statistically controlling for changes in distress. Changes in the interaction between self-criticism and distress predicted changes in suicide ideation and changes in the interaction between self-criticism and neediness tended to predict changes in suicide ideation. Results are discussed with regard to their implications for psychological intervention.     

The Effect of Religious Belief and Forgiveness on Coping with Diabetes

We aimed to investigate the relationship of religious beliefs and forgiveness in diabetic patients with various sociodemographic characteristics, emotional problems and glycaemic control. The study comprises 100 patients diagnosed with type 2 DM. We used a data collection form, the Scale of Forgiveness and Religiosity (SFR), Problem Areas in Diabetes Scale (PAID), Beck Depression Inventory (BDI), State-Trait Anxiety Inventory (STAI) and the Audit of Diabetes-Dependent Quality of Life (ADDQoL). We also recorded blood glucose and HbA1c test results. A statistically significant relationship was determined only between the scores of the STAI-I and the religious belief scales (r = 0.198, p = 0.049). A statistically significant negative relationship was determined between the forgiveness scale points and the BDI (r = 0.326, p = 0.001), the STAI-II (r = 0.308, p = 0.002) and PAID (r = 0.313, p = 0.001) and a positive correlation with ADDQoL (r = 0.284, p = 0.004). To conclude, forgiveness by patient himself or others reduced the emotional problems which were experienced related to diabetes by reducing stress levels and could increase quality of life.     

Team Development: Definition,Measurement and Relationships with Team Effectiveness

This article describes the development and validation of a theory-based measure of team development. Drawing on 3 independent samples, including multisource and 2-wave data, we found support for the scale’s theoretical multidimensionality. Convergent and discriminant validity was established, and criterion-related validity was determined through the scale’s relation with 3 facets of team effectiveness: viability, extrarole performance, and reputation. We conclude that the 29-item measure is valid and reliable for the assessment of team development. Theoretically, we shed light on the dimensionality of team development and extend the available knowledge on its nomological network. Practical implications for enhancing team effectiveness via team development are discussed.     

Choking under pressure and working memory capacity: When performance pressure reduces fluid intelligence

Recent findings (Beilock & Carr, 2005) have demonstrated that only individuals with a high working memory capacity (WMC) “choke under pressure” on math problems with high working memory demands. This suggests that performance pressure hinders those who are the most qualified to succeed, because it consumes the WMC they usually rely on to achieve superior performance. This puts into question the use of performance in high-pressure situations as a means of distinguishing individuals with lesser or greater WMC potentials. While addressing several limitations of past research, we offer evidence that such choking (1) occurs only in individuals with high WMC, because of their anxiety-ridden perceptions of high-stakes situations, and (2) is not confined to tasks involving acquired skills and knowledge, but encompasses fluid reasoning abilities or intelligence (Gf). These findings have strong implications for assessments of people’s intellectual capacities in academic, clinical, work, and research settings.     

Directional preferences in turning behavior of girls and boys

Turning biases in humans and animals are known to be related to dopaminergic asymmetry between the brain hemispheres. A laboratory method, in which turning preference was evaluated, was adapted based upon the turning of the subject toward a particular sound in a square room. One of the aims of this study was to investigate the reliability of this method with children, and the other aim was to research the turning preference in boys and girls. 31 children between 7 and 13 yr. old volunteered as subjects, and 17 subjects were retested. The subjects tended significantly to turn leftward (60.1%), and fewer girls (53.7%) turned to the left than boys (66.2%). The correlation between the test and the retest was significant (r=.79, p< .01). Most studies have indicated that humans in childhood and adulthood exhibit left-turning preference, but conflicts between the results obtained on different types of rotation tasks have suggested that hemispheric dopaminergic activity might affect preference. That needs study.
