Alcohol consumption has been associated with increases in aggressive behaviour. However, experimental evidence of a direct association is equivocal, and mechanisms that may underlie this relationship are poorly understood. One mechanism by which alcohol consumption may increase aggressive behaviour is via alterations in processing of emotional facial cues. We investigated the effects of acute alcohol consumption on sensitivity to facial expressions of emotion. Participants attended three experimental sessions where they consumed an alcoholic drink (0.0, 0.2 or 0.4 g/kg), and completed a psychophysical task to distinguish expressive from neutral faces. The level of emotion in the expressive face varied across trials the threshold at which the expressive face was reliably identified and measured. We observed a significant three-way interaction involving emotion, participant sex and alcohol dose. Male participants showed significantly higher perceptual thresholds for sad facial expressions compared with female participants following consumption of the highest dose of alcohol. Our data indicate sex differences in the processing of facial cues of emotional expression following alcohol consumption. There was no evidence that alcohol altered the processing of angry facial expressions. Future studies should examine effects of alcohol expectancy and investigate the effects of alcohol on the miscategorisation of emotional expressions.
Cognitive skills training has been linked to greater skills, self-efficacy, and performance. Although research in a variety of organizational settings has demonstrated training efficacy, few studies have assessed cognitive skills training using rigorous, longitudinal, randomized trials with active controls. The present study examined cognitive skills training in a high-risk occupation by randomizing 48 platoons (N = 2,432 soldiers) in basic combat training to either (a) mental skills training or (b) an active comparison condition (military history). Surveys were conducted at baseline and 3 times across the 10-week course. Multilevel mixed-effects models revealed that soldiers in the mental skills training condition reported greater use of a range of cognitive skills and increased confidence relative to those in the control condition. Soldiers in the mental skills training condition also performed better on obstacle course events, rappelling, physical fitness, and initial weapons qualification scores, although effects were generally moderated by gender and previous experience. Overall, effects were small; however, given the rigor of the design, the findings clearly contribute to the broader literature by providing supporting evidence that cognitive training skills can enhance performance in occupational and sports settings. Future research should address gender and experience to determine the need for targeting such training appropriately.
We examine the structure of soldier's psychological skills and assess the relationship between psychological skills profiles and physical performance with data from 427 soldiers from a Stryker Brigade. Exploratory factor analyses results provided empirical support for a three-factor structure that included foundation skills, psychosomatic skills, and cognitive skills. Cluster analysis revealed three emergent psychological skills profile groups: (a) strong skills, (b) weak skills, and (c) fearful focus clusters. Soldiers in the strong psychological skill profile group performed better than their peers in the other profile groups on the Army Physical Fitness Test (APFT) performance measure. We discuss the implications of our findings for theory, research, and practice.Empirical evidence suggests that psychological skills are crucial to high-level expert performance across a range of tasks and populations (e.g.
Warrior transition unit (WTU) cadre members are exposed to a variety of stressors that put them at risk for adverse conditions and events. Resilience may be a construct capable of moderating some of these potential negative outcomes. In turn, mental toughness is a concept associated with resilience that may provide a unique framework from which to train resilient behavior. This article explored associations between resilience and several mental skills that are assumed to be related to mental toughness, in a sample (n = 27) of WTU cadre members in the U.S. Army. Instruments included the Ottawa Mental Skills Inventory (OMSAT-3) and the Resilience Scale (RS). Both cognitive mental skills and emotion management skills were positively associated with resilience. Results also indicated a model specifying emotion management as a mediator of the relationship between cognitive skills and resilience was consistent with the study data.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
