The degree to which response complexity affects the ability of moderately mentally retarded adults to perform on a coincident timing task was examined. In Experiment 1 subjects were required to depress a key to estimate accurately the arrival of a moving target at a predetermined coincident point. Analyses of both constant and variable error scores suggested that subjects had difficulty inhibiting their responses and that an optimal exposure distance for the task existed. In Experiment 2 subjects were required to make a movement response to the target. Subjects made more constant errors in this experiment but improved when provided maximum target preview. These mixed findings are discussed in terms of subjects' impulsivity and their sensitivity to the characteristics of the display.
研究了反应复杂性对中度智力迟钝成年人在同步计时任务中表现能力的影响程度。在实验1中，要求受试者按下一个按键，以准确估计移动目标到达预定同步点的时间。对恒定误差和可变误差分数的分析表明，受试者在抑制反应方面存在困难，并且该任务存在一个最佳曝光距离。在实验2中，要求受试者对目标做出动作反应。在这个实验中，受试者产生了更多的恒定误差，但在获得最大目标预视时有所改善。根据受试者的冲动性及其对显示特征的敏感性对这些混合结果进行了讨论。
