Research showing that activation of negative stereotypes can impair the performance of stigmatized individuals on a wide variety of tasks has proliferated. However, a complete understanding of the processes underlying these stereotype threat effects on behavior is still lacking. The authors examine stereotype threat in the context of research on stress arousal, vigilance, working memory, and self-regulation to develop a process model of how negative stereotypes impair performance on cognitive and social tasks that require controlled processing, as well as sensorimotor tasks that require automatic processing. The authors argue that stereotype threat disrupts performance via 3 distinct, yet interrelated, mechanisms: (a) a physiological stress response that directly impairs prefrontal processing, (b) a tendency to actively monitor performance, and (c) efforts to suppress negative thoughts and emotions in the service of self-regulation. These mechanisms combine to consume executive resources needed to perform well on cognitive and social tasks. The active monitoring mechanism disrupts performance on sensorimotor tasks directly. Empirical evidence for these assertions is reviewed, and implications for interventions designed to alleviate stereotype threat are discussed.
越来越多的研究表明,负面刻板印象的激活会损害受污名化个体在各种任务中的表现。然而,对于这些刻板印象威胁对行为产生影响的潜在过程,仍缺乏全面的理解。作者们在关于应激唤醒、警觉、工作记忆和自我调节的研究背景下,审视刻板印象威胁,以构建一个过程模型,说明负面刻板印象如何损害需要控制性加工的认知和社会任务,以及需要自动加工的感觉运动任务的表现。作者们认为,刻板印象威胁通过三种不同但相互关联的机制破坏表现:(a) 一种直接损害前额叶加工的生理应激反应,(b) 积极监控表现的倾向,以及 (c) 为了自我调节而抑制负面思想和情绪的努力。这些机制共同消耗了在认知和社会任务中良好表现所需的执行资源。积极监控机制直接破坏感觉运动任务的表现。文中回顾了这些论断的实证证据,并讨论了旨在减轻刻板印象威胁的干预措施的意义。
