Abstract

Background and objectives Specificity of practice proposes optimal performance is linked to the conditions under which learning occurred. The present study investigated this effect within a pressure context to determine whether offline and/or online control processes develop specificity through the introduction or removal of performance pressure. Methods Forty novices practiced a two-dimensional stimulus-response discrimination task in one of four groups; two control (control-control and anxiety-anxiety) and two experimental (control-anxiety and anxiety-control). In the experimental groups, participants experienced a switch in conditions of pressure both early and late in practice, i.e., practiced in low-pressure and transferred to high-pressure (control-anxiety group) or the reverse of this (anxiety-control group). Results A significant acquisition-to-transfer decrement in performance occurred for both experimental groups. This offers support for a pressure-performance specificity effect because a change in conditions of pressure (regardless if that was an increase or decrease) resulted in performance decrements. Furthermore, the reaction time measure of offline control was affected by the change to a significantly greater extent than the movement time measure of online control. Conclusions Increases in offline control processes was a performance strategy adopted to combat the disruption that pressure caused to the processes associated with adjusting or planning movements online.

摘要

背景与目的

实践的特异性提出,最佳表现与学习发生的条件有关。本研究在压力环境下调查了这种效应,以确定离线和/或在线控制过程是否通过引入或消除绩效压力来发展特异性。

方法

40 名新手在四个小组中的一个小组中练习二维刺激-反应辨别任务;两个对照组(控制-控制和焦虑-焦虑)和两个实验组(控制-焦虑和焦虑-控制)。在实验组中,参与者在练习的早期和晚期都经历了压力条件的转变,即在低压力下练习并转移到高压力(控制-焦虑组)或反之(焦虑-控制组)。

结果

两个实验组的表现均出现了明显的习得-转移衰减。这为压力表现特异性效应提供了支持,因为压力条件的变化(无论增加还是减少)都会导致表现下降。此外,离线控制的反应时间测量受到的影响明显大于在线控制的运动时间测量。

结论

离线控制过程的增加是一种表现策略,用于应对压力对在线调整或规划运动相关过程的干扰。
