To determine if direction of response affects reaction time, we measured the time for hand response to a visual stimulus, using a sensitive, microprocessor-based testing device to determine simple reaction time (RT), choice RT, and decision time. Mean simple RT was 207 +/- 3.7 msec. (mean +/- SEM); mean choice RT was 268 +/- 4.2 msec; and mean decision time was 61 msec. No differences were noted for leftward versus rightward movements, or midline versus lateral movements. Choice RT increased by 1.49 msec./yr. of age. Simple RT increased significantly with age for the nondominant hand, but not for the dominant hand. Right-handed subjects were more rapid with the dominant hand for choice RT. We conclude that dominance of hand tested and test initiation mechanism have major effects, but direction of movement in the lateral plane has little effect on reaction time.
为了确定反应方向是否会影响反应时间，我们使用基于微处理器的灵敏测试设备测量手部对视觉刺激的反应时间，以确定简单反应时间（RT）、选择反应时间和决策时间。平均简单反应时间为207±3.7毫秒（平均值±标准误）；平均选择反应时间为268±4.2毫秒；平均决策时间为61毫秒。向左与向右运动、中线与侧向运动之间未发现差异。选择反应时间随年龄每年增加1.49毫秒。非优势手的简单反应时间随年龄显著增加，但优势手则不然。右利手受试者优势手的选择反应时间更快。我们得出结论，测试手的优势和测试启动机制有主要影响，但在侧面平面上的运动方向对反应时间影响很小。
