The interaction between preparatory set and response complexity was demonstrated in an experiment investigating the reaction latency of discrete arm movements. Following simple finger-lift reaction-time (RT) trials, subjects performed simple and complex versions of a discrete horizontal arm movement under one of two enforced preparatory set conditions. For the simple task, requiring subjects to attend to the components of the response prior to stimulus presentation (enforced motor set) produced significantly shorter RTs than when concentration was on the stimulus (enforced sensory set). However, RT differences for the complex version of the task failed significance. Theoretical implications of the results for Henry's (1960) memory drum theory of neuromotor reaction were discussed.
在一项研究离散手臂运动反应潜伏期的实验中，展示了准备状态与反应复杂性之间的相互作用。在简单的手指抬起反应时（RT）试验之后，受试者在两种强制准备状态条件之一的情况下，执行离散水平手臂运动的简单和复杂版本。对于简单任务，要求受试者在刺激呈现之前关注反应的组成部分（强制运动准备状态）所产生的反应时，比将注意力集中在刺激上（强制感觉准备状态）时显著更短。然而，该任务复杂版本的反应时差异未达到显著水平。讨论了这些结果对亨利（1960年）神经运动反应记忆鼓理论的理论意义。
