摘要

目的:基于Chalabaev et al.(2013)的研究表明,在刻板印象威胁(ST)情境下,简单运动任务中的力产生速度会受到影响,本研究旨在复制这一结果,并测试视觉空间工作记忆(VSWM)在ST效应中的作用。方法:21名女运动员在等速测力仪(Biodex)上进行膝关节伸肌的最大自主收缩,分别在中性、ST和ST的心理意象条件下。在每种情况下,测量了速度指标——开发速率力(RFD)。VSWM和回避相关的过程在一个单独的时间测量。结果:数据证实,当刻板印象威胁引入时,RFD降低,但收缩前阶段的运动心理意象阻止了这种影响。此外,在ST条件下,回避相关过程不影响RFD。相反,更高的VSWM表现与更高的RFD相关。结论:这些研究结果表明,ST对简单运动任务的影响可以通过工作记忆的改变来解释,这种改变损害了收缩前阶段的运动准备过程。

Stereotype Threat Effect on a Simple Motor Task: An Investigation of the Visuo-Spatial Working Memory.

Purpose: Based on the Chalabaev et al. (2013) study showing that in a Stereotype Threat (ST) situation the velocity of force production in a simple motor task can be affected, this study aimed to replicate this result and tested the role of Visuo-Spatial Working Memory (VSWM) in the ST effect. Method: Twenty one female athletes performed maximum voluntary contractions of the knee extensor muscles on an isokinetic dynamometer (Biodex), under neutral, ST, and ST with mental imagery conditions. The Rate Force of Development (RFD), a velocity indicator, was measured under each condition. VSWM and avoidance-related processes were measured in at a separate time. Results: Data confirmed that the RFD decreased when the stereotype threat was introduced, but also that mental imagery of the movement in the pre-contraction stage prevented this effect. Moreover, in the ST condition avoidance-related processes did not affect the RFD. In contrast, higher VSWM performance was associated with higher RFD. Conclusion: These findings suggest that the ST effects on a simple motor task can be explained by an alteration of working memory which impairs movement preparatory processes in the pre-contraction stage.

期刊介绍: Research Quarterly for Exercise and Sport publishes research in the art and science of human movement that contributes significantly to the knowledge base of the field as new information, reviews, substantiation or contradiction of previous findings, development of theory, or as application of new or improved techniques. The goals of RQES are to provide a scholarly outlet for knowledge that: (a) contributes to the study of human movement, particularly its cross-disciplinary and interdisciplinary nature; (b) impacts theory and practice regarding human movement; (c) stimulates research about human movement; and (d) provides theoretical reviews and tutorials related to the study of human movement. The editorial board, associate editors, and external reviewers assist the editor-in-chief. Qualified reviewers in the appropriate subdisciplines review manuscripts deemed suitable. Authors are usually advised of the decision on their papers within 75–90 days.
