This article examines the programming of relatively long sequences of action with the control of sequential movements being effected through the use of a tapping task involving a sequence of five taps. Subjects were required to tap with their right hand at rates of 150, 200, and 250 ms. There were two conditions, with subjects being required either to increase, in condition 1, or to decrease, in condition 2, the force at one of the five tap positions (all five tap positions were examined), then return to the previous force level. Changes in timing resulting from variations in the force characteristics have previously been discussed in terms of changes in the organizational time required (Semjen, Garcia-Colera, & Requin, 1984). The current study breaks the intertap interval down into two separate components: the contact interval (finger in contact with the key) and the non-contact interval (interval preceding the tap). Although changes in the non-contact interval could be explained in terms of changes in the organizational time required, changes in the contact interval appeared to be a result of the mechanical changes in force.
本文通过一项涉及五次敲击序列的敲击任务来控制连续动作，研究相对较长动作序列的编程。要求受试者用右手以150、200和250毫秒的速率进行敲击。有两种条件，在条件1中，要求受试者增加，在条件2中，要求受试者降低五次敲击位置之一（检查了所有五个敲击位置）的力度，然后回到之前的力度水平。先前已根据所需组织时间的变化讨论了由力特性变化导致的时间变化（Semjen、Garcia-Colera和Requin，1984年）。当前研究将敲击间隔分解为两个独立的组成部分：接触间隔（手指与按键接触的间隔）和非接触间隔（敲击前的间隔）。虽然非接触间隔的变化可以根据所需组织时间的变化来解释，但接触间隔的变化似乎是力的机械变化的结果。
