Young adults’ decreased engagement in politics has theoretically been linked to issues in personal identity formation, but there are few and limited empirical studies on the subject. We examined, in a Finnish community sample of young adults (N = 744), for the first time the associations of diverse measures of political engagement with the identity processes and identity statuses as measured by the Dimensions of Identity Development Scale. In general, both the variable- and person-oriented analyses indicated that having future commitments but also exploring alternatives to some extent were associated with stronger political engagement. The links and differences among identity processes, statuses, and political engagement were, nonetheless, weaker than could have been expected. 相似文献

Perceptual grouping modulates performance in attention tasks such as partial report and change detection. Specifically, grouping of search items according to a task-relevant feature improves the efficiency of visual selection. However, the role of task-irrelevant feature grouping is not clearly understood. In the present study, we investigated whether grouping of targets by a task-irrelevant feature influences performance in a partial-report task. In this task, participants must report as many target letters as possible from a briefly presented circular display. The crucial manipulation concerned the color of the elements in these trials. In the sorted-color condition, the color of the display elements was arranged according to the selection criterion, and in the unsorted-color condition, colors were randomly assigned. The distractor cost was inferred by subtracting performance in partial-report trials from performance in a control condition that had no distractors in the display. Across five experiments, we manipulated trial order, selection criterion, and exposure duration, and found that attentional selectivity was improved in sorted-color trials when the exposure duration was 200 ms and the selection criterion was luminance. This effect was accompanied by impaired selectivity in unsorted-color trials. Overall, the results suggest that the benefit of task-irrelevant color grouping of targets is contingent on the processing locus of the selection criterion. 相似文献

The attentional blink (AB) refers to the finding that the perception of the second of two targets (T2) is impaired when presented in close temporal proximity to the first target (T1). An exception to this deficit occurs when T2 immediately follows T1, an effect referred to as lag 1 sparing. So far, it has been unclear whether the AB is location specific or nonspatial in nature. Most demonstrations of an AB across different locations have shown an absence of lag 1 sparing, due to accompanying spatial switch costs. This means that the AB pattern itself may be explained through such switch costs. In this study, to minimize spatial switch costs, attention was made to move continuously across multiple locations by aid of a cue. An AB across different locations was found, including lag 1 sparing. We conclude that the AB and lag 1 sparing are not tied to a location but represent a central deficit, in line with current theory. 相似文献

The goal of the present paper is to construct a formal explication of the pluralistic ignorance explanation of the bystander effect. The social dynamics leading to inaction is presented, decomposed, and modeled using dynamic epistemic logic augmented with ‘transition rules’ able to characterize agent behavior. Three agent types are defined: First Responders who intervene given belief of accident; City Dwellers, capturing ‘apathetic urban residents’ and Hesitators, who observe others when in doubt, basing subsequent decision on social proof. It is shown how groups of the latter may end in a state of pluralistic ignorance leading to inaction. Sequential models for each agent type are specified, and their results compared to empirical studies. It is concluded that only the Hesitator model produces reasonable results. 相似文献

With this study we seek to contribute to the research on the emergence of transactive memory, that is, the knowledge of “who knows what”, as part of the structural component of transactive memory systems (TMSs). Based on our theoretical model of team learning and transactive memory development, we analyse the relationships among different team learning behaviours and transactive memory during various phases of team development. We use a longitudinal design with three points of measurement at the beginning, in the middle, and at the end of a semester, to examine real student project teams over their full life cycle. The results support our presumptions of phase-specific influences of team learning behaviours on transactive memory development. This shows that knowledge-based processes (storage and retrieval) play a more important role during early stages of project-based teamwork, followed by a shift to a higher relevance of communication-based processes (reflection and co-construction) in later stages. Implications for further research and team management phenomena are discussed. 相似文献
