在3个实验中研究了短、快速序列瞄准响应的制备和在线控制。参与者（实验1和2中的N = 12，实验3中的20）产生3段响应（a）在自我启动，简单反应时（RT），和选择RT范式（实验1）;（B）没有视觉反馈下的自我启动条件（实验2）;（c）有和没有视觉反馈下的简单RT条件（实验3）。在所有条件下，参与者发起运动，以响应外部命令信号，第二个响应段进行一贯慢于之前和之后的响应段。无论是否有视觉反馈，这种分段运动时间的模式都被发现，但当参与者在有或没有视觉反馈的情况下自发反应时，这种模式并不明显。研究结果排除了可能性，即受试者的视觉反馈的使用是负责RT条件下的第二反应段的放缓，并建议快速顺序瞄准反应的编程可以分布在前和postinitiation间隔。
The preparation and on-line control of short, rapid sequential aiming responses were studied in 3 experiments. Participants (N = 12 in Experiments 1 and 2, and 20 in Experiment 3) produced 3-segment responses (a) within self-initiation, simple reaction time (RT), and choice RT paradigms (Experiment 1); (b) without visual feedback under self-initiation conditions (Experiment 2); and (c) with and without visual feedback under simple RT conditions (Experiment 3). In all conditions in which participants initiated movement in response to an external imperative signal, the 2nd response segment was performed consistently slower than preceding and succeeding response segments. That pattern of segmental movement times was found whether or not visual feedback was available but was not evident when participants self-initiated their responses with or without visual feedback. The findings rule out the possibility that subjects' use of visual feedback is responsible for the slowing of the 2nd response segment under RT conditions and suggest that the programming of rapid sequential aiming responses can be distributed in pre- and postinitiation intervals.
