Abstract

The aim of this study was to assess the effect of stress on a previously acquired motor coordination. Following a longitudinal learning experiment, four participants performed oscillations on a ski simulator, either in normal or stressful conditions. The results showed that the amplitude of the oscillations decreased under stress, but no significant effect was seen regarding coordination, suggesting the strong resistance to stress of overlearned behaviour. Nevertheless, for one participant, a transient regression towards a former stage of learning was observed. This result was consistent with the regression hypothesis formulated by Fuchs (1962).

摘要

本研究的目的是评估压力对先前习得的运动协调性的影响。在一项纵向学习实验之后，四名参与者在滑雪模拟器上进行摆动，分别处于正常或压力条件下。结果表明，在压力下摆动幅度减小，但在协调性方面未观察到显著影响，这表明过度学习行为对压力具有较强的抵抗力。然而，对于一名参与者，观察到其暂时回归到学习的前一阶段。这一结果与富克斯（1962年）提出的回归假说一致。
