Abstract

The purpose of this study was to determine the effects of uncertainties of time and occurrence on reaction time of mildly handicapped students. 33 students were randomly assigned to the following treatment groups: no catch-trials, 10% catch-trials, and 20% catch-trials. Randomly varied foreperiods of 1.5, 3.0, and 4.5 sec. were used in a reaction time task. The role of catch-trials varied over four days of testing. Reaction times following 3.0- and 4.5-sec. were significantly faster than measurements following a 1.5-sec. foreperiod.

摘要

本研究的目的是确定时间和事件不确定性对轻度残疾学生反应时间的影响。33名学生被随机分配到以下处理组：无捕捉试验组、10%捕捉试验组和20%捕捉试验组。在一项反应时间任务中，使用了1.5秒、3.0秒和4.5秒的随机变化的预备时间。捕捉试验的作用在四天的测试中有所不同。3.0秒和4.5秒后的反应时间明显快于1.5秒预备时间后的测量结果。
