The time required to begin movement toward a panel of lights and switches of two different complexity levels was investigated in both a between-subjects and within-subjects design. In the between-subjects design, the mean RT on the subjects' first trial was longer to the more complex task, supporting the memory-drum theory of Henry and Rogers (1960). In the within-subjects design, a significant complexity x order x blocks interaction showed that the subjects receiving the less complex task first responded differently than subjects receiving the more complex task first. Implications for experimental design in investigations of task complexity are discussed.
在一项被试间设计和一项被试内设计中，研究了向两组不同复杂程度的灯光和开关移动所需的时间。在被试间设计中，被试首次试验时，完成较复杂任务的平均反应时间更长，这支持了亨利和罗杰斯（1960年）的记忆鼓理论。在被试内设计中，显著的复杂度×顺序×组块交互作用表明，先接受较简单任务的被试与先接受较复杂任务的被试反应不同。文中讨论了任务复杂性研究中实验设计的意义。
