Mental fatigue influence on effort-related cardiovascular response: difficulty effects and extension across cognitive performance domains

Two experiments investigated cardiovascular effects of mental fatigue as a function of (1) the difficulty of the cognitive challenge with which participants were confronted, and (2) the relevance of that challenge to the activity that instigated the fatigue. In the first, participants performed an easy (fatigue low) or difficult (fatigue high) counting task and then were presented an arithmetic challenge (task B relevance high) or a scanning challenge (task B relevance low) with instructions that they would avoid a noise if they attained a modest performance standard. Analysis of blood pressure responses assessed during the work periods revealed fatigue main effects, reflecting stronger responses for High Fatigue participants, regardless of the character of the second task. In the second, the procedure was the same except that it included a high performance standard and provided the chance to win a prize. Analysis of the pressure data revealed fatigue x work period interactions, reflecting relatively stronger responses among High Fatigue participants in work period 1, but relatively weaker responses among these participants in work period 2. Results confirm previous findings and support an analysis of fatigue influence on effort and associated cardiovascular responses. They also argue against the idea that mental fatigue influence may be confined to relevant cognitive performance realms.

Active and Avoidant Coping and Coping Efficacy as Mediators of the Relation of Maternal Involvement to Depressive Symptoms among Urban Adolescents

Our study tested an extension of the social resource model in an urban sample of 129 African American and 114 European American adolescents. Maternal involvement was positively related to the use of active and avoidant coping strategies among youth of both ethnicities. Additionally, use of active coping strategies was related to greater coping efficacy, which, in turn, was associated with less depressive symptomatology. For African Americans, avoidant coping was related to greater coping efficacy, which, in turn, was associated with less depressive symptoms. For European Americans, avoidant coping was not significantly related to coping efficacy. Our findings underscore the importance of examining developmental models across ethnic/racial groups and suggest that adolescent mental health programs may benefit from culturally sensitive attention to coping beliefs and practices.     

Information elaboration and team performance: Examining the psychological origins and environmental contingencies

Information elaboration enables functionally diverse teams to transform their breadth of knowledge resources into actionable solutions to complex problems. The current study advances information elaboration theory and research in two ways. First, we identify how team ability and social motivation composition characteristics provide the psychological origins of complex information processing efforts. Second, we identify environmental turbulence as an important boundary condition, clarifying when information elaboration benefits team performance and when it does not. These ideas were tested in a sample of 4-person self-managed teams (N = 68) which were functionally diverse and performed a cooperative strategic decision-making task. Results indicate that cognitive ability equips teams with the “can do” ability for complex elaboration efforts through emergent team mental models, whereas low preferences for self-reliance provide the “will do” motivation for in-depth information exchange through collective leadership. In turn, teams benefited from information elaboration in turbulent but not stable environments.     

Intimate Partner Violence and Subsequent Depression: Examining the Roles of Neighborhood Supportive Mechanisms

This study examines the direct effects of neighborhood supportive mechanisms (e.g., collective efficacy, social cohesion, social networks) on depressive symptoms among females as well as their moderating effects on the impact of IPV on subsequent depressive symptoms. A multilevel, multivariate Rasch model was used with data from the Project on Human Development in Chicago Neighborhoods to assess the existence of IPV and later susceptibility of depressive symptoms among 2959 adult females in 80 neighborhoods. Results indicate that neighborhood collective efficacy, social cohesion, social interactions, and the number of friends and family in the neighborhood reduce the likelihood that females experience depressive symptoms. However, living in areas with high proportions of friends and relatives exacerbates the impact of IPV on females’ subsequent depressive symptoms. The findings indicate that neighborhood supportive mechanisms impact interpersonal outcomes in both direct and moderating ways, although direct effects were more pronounced for depression than moderating effects. Future research should continue to examine the positive and potentially mitigating influences of neighborhoods in order to better understand for whom and under which circumstances violent relationships and mental health are influenced by contextual factors.     

Role ambiguity,role conflict,team conflict,cohesion and collective efficacy in sport teams: A multilevel analysis

ObjectivesThis study examines how perceptions of role ambiguity, role conflict, team conflict, and cohesion can predict collective efficacy in sports teams.DesignWe adopted a longitudinal perspective, taking measures at the beginning, the middle, and the end of a sport season.MethodsThe participants were professional female and male football players, who participated in the First and Second Divisions in Spain. They completed a multi-section questionnaire assessing role ambiguity, role conflict, cohesion and collective efficacy.ResultsMultilevel modelling analysis showed that perceptions of team conflict and cohesion, at the interpersonal and interteam levels, can predict changes in collective efficacy. However, individual perceptions of role ambiguity and role conflict were not relevant in establishing a team's confidence.ConclusionsThese results suggest interesting practical applications for coaches and sports psychologists in the professional sphere.     

Perceptions of the value of Collective Worship amongst trainee teachers in England

This article draws on a survey conducted with primary school trainee teachers in a university in England. The survey set out to investigate their knowledge, understanding and their view about the role that Collective Worship (CW) plays in schools. A sample of 125 participants contributed to the findings of this inquiry by completing a questionnaire. The results demonstrate that these students think that CW makes a significant contribution to the spiritual, moral, social, cultural (SMSC), and emotional and intellectual development of pupils. The most significant finding is that they think worship should be retained. Their views are important as they provide further insights for the debates currently taking place about the status and nature of worship in schools. The research has implications for further studies and to develop the overall knowledge about CW among trainee teachers.     

Still underdetected – Social norms and collective efficacy predict the acceptance of electric vehicles in Germany

The role of social identity variables for predicting environmental decisions may often be underdetected by psychological lay people. Applying this to the acceptance of electric vehicles (EVs) in Germany we investigated whether social norms and collective efficacy predict EV acceptance and what psychological laypersons who are either EV experts or EV non-experts think predicts EV acceptance. In preliminary interview studies we explored the beliefs of EV experts and EV non-experts. In a survey study, we then tested whether cost-related advantages and disadvantages were predictive of EV acceptance and whether norms and collective efficacy have independent effects even when controlling for cost-related factors and demographic variables. Results suggest that both EV experts and EV non-experts considered cost-related factors as much more important than social identity processes. However, hierarchical regression analyses of the survey data showed that norms and collective efficacy have equal or even stronger effects on acceptance than cost-related factors. We discuss the theoretical and practical implications of these findings.     

The breadth and mnemonic consequences of the youth bias

We have recently demonstrated the existence of the youth bias, referring to a tendency to favour adolescence and early adulthood over other lifetime periods when making inferences about the timing of important public events across the lifespan of a typical individual within one's culture. The youth bias integrates two discrete lines of research, that is, the literature on the privileged status of adolescence and early adulthood in human memory and cognition, and the literature on cognitive biases. Here we first examined whether the youth bias holds for specific categories of public events (i.e., deaths of public figures, United States presidential elections, and sporting events). We then investigated the possible role of the youth bias in structuring recall for public events, by probing, within subjects, for the relation between: (1) these expectations of the timing, in a typical person's life, of the most important exemplar from each public event category, and (2) the age at which the cited event occurred on a recall question asking participants to cite the most important exemplar, in their own lifetime, from each category. We found a youth bias for each category. Additionally, responses to the youth bias question were correlated with the age at which the recalled event occurred, but only where particularly salient historical events did not play a central role in driving recall (i.e., for sporting events). We conclude that the youth bias holds across different types of public events and provides a default structure for organizing recall of public events.     

The two‐sided nature of individual and intragroup experiences in the aftermath of collective victimization: Findings from four diaspora groups

Most social psychological research on collective victimhood has examined its consequences for intergroup relations. Less attention has been paid to individual and intragroup processes associated with collective victimization, which the present study aimed to examine. We conducted eight focus group interviews among four diaspora communities (Armenian Americans, Burundian refugees, Jewish Americans, Nepali‐speaking Bhutanese refugees) with historical or more recent experiences of collective victimization. Thematic analysis revealed three major foci shared across communities (but with different emphases within each focus), which included juxtaposed themes that highlight the two‐sided nature of experiencing and coping with collective victimization and its aftermath: Vulnerability and struggle versus resilience and strength, loss versus continuity and renewal, and silence about versus transmission of knowledge about ingroup victimization. These findings illustrate how groups integrate seemingly opposite poles of collective victimization that characterize this complex and multifaceted experience, which has important theoretical implications.
