本实验旨在探讨年龄与弹道运动行为背后的反应规划操作之间的关系。在最初的实验中，两个不同年龄组的女性受试者（平均年龄21.9岁和69.1岁）在预编程、编程和重编程条件下，在两个运动方向（左或右）中的一个方向上进行右手和手臂的目标运动。这些操作是通过提供关于即将发生的运动方向的预先信息，并操纵预先信息与随后的反应信号之间的对应程度来检验的。结果表明，年龄较大的被试反应速度和移动速度比年龄较小的被试慢，但年龄与三种反应编程条件之间不存在交互作用。这些发现表明，这些过程的基本操作特征不受年龄增长的影响。此外，与年龄和反应编程条件无关，对右侧的反应比对左侧的反应启动得更快。这种差异在重编程中尤为突出。第二个实验，使用了一种新的刺激-反应映射，复制了左-右在启动时间上的差异；当左手被用来执行指定的动作时，这种差异被逆转了，这表明这一发现确实是一种反应编程现象。进一步的讨论集中在重新编程的可能操作上。
The present experiments were conducted to investigate the relationship between age and the response programming operations underlying the execution of a ballistic motor act. In an initial experiment, two separate age groups of female subjects (mean ages of 21.9 and 69.1 years) performed aimed-movements of the right hand and arm in one of two movement directions (left or right), under preprogramming, programming, and reprogramming conditions. These operations were examined by providing advance information about the direction of an impending movement and manipulating the degree of correspondence between the advance information and a subsequent reaction signal. The results indicated that subjects in the older age group reacted and moved more slowly than subjects in the younger age group, however, there was no interaction between age and the three response programming conditions. Such findings indicated that the basic operational characteristics of these processes remain unaffected with advancing chronological age. Also, irrespective of age and response programming condition, responses to the right were initiated faster than responses to the left. This difference was especially accentuated for reprogramming. A second experiment, using a new stimulus-response mapping, replicated the left-right difference in initiation time; this difference was reversed when the left hand was used to execute the designated movement, indicating that this finding is indeed a response programming phenomenon. Further discussion focused on the possible operations underlying reprogramming.
