据报道，一项实验定位并比较了三个年龄组（青年（18-25 岁）、中年（40-50 岁）和老年（65-75 岁））之间的运动规范时间，以评估运动计划过程是否是老年人中常见的反应启动时间减慢的部分原因。使用运动预提示范式，其中 24 名受试者（8 岁/年龄组）在命令性响应信号之前接收到没有、部分或完整的运动任务信息。结果表明，老年人的反应时间、运动时间、信息传输速度较慢且错误较多。虽然结果表明老年人可以利用预先信息来准备即将进行的动作，但他们对手臂、方向和幅度的指定时间明显较慢。这些数据被解释为提供了证据，表明在老年人中观察到的反应时间减慢的部分原因是指定运动维度所需的时间增加。
An experiment is reported which localizes and compares movement specification times between three age groups, young (18–25 yrs.), middle (40–50 yrs.), and elderly (65–75 yrs.), in order to assess whether movement planning processes are partially responsible for the commonly observed slowing of response initiation time in the elderly. A movement precuing paradigm was used in which 24 subjects (8/age group) received either no, partial, or complete movement task information prior to the imperative response signal. The results established that the elderly had slower reaction times, movement times, information transmission rates and more errors. While the results indicated that the elderly could use precue information to prepare an upcoming movement, their specification times for arm, direction, and extent were markedly slower. The data are interpreted as providing evidence that part of the slowing in reaction time observed in the elderly is due to the increased time required to specify a dimension of movement.
