We investigated the time course of the amplitude specification of rapid bimanual reversal movements (lateral displacements on two digitizers). To this end we used the timed-response paradigm in which the response has to be initiated synchronously with an auditory signal. Information about the required amplitudes was presented at various times before the synchronization signal. Consistent with previous results, the progression of amplitude specification was reflected in the dependence of the amplitudes of the reversal movements on the time interval between amplitude information and synchronization signal. Same or different amplitudes for the hands were used to examine cross-talk at the programming level of the two-level model of intermanual interference. The results indicate the existence of cross-talk in particular at short intervals between information about amplitude and movement initiation. This is consistent with the notion that cross-talk between concurrent processes of amplitude specification is transient and vanishes as the time available for motor programming increases.
我们研究了快速双手反向运动（在两个数字化仪上的横向位移）幅度设定的时间进程。为此，我们采用了定时反应范式，其中反应必须与听觉信号同步启动。关于所需幅度的信息在同步信号之前的不同时间呈现。与先前的结果一致，幅度设定的进展反映在反向运动的幅度对幅度信息与同步信号之间时间间隔的依赖性上。使用双手相同或不同的幅度来检验双手干扰两级模型编程层面的串扰。结果表明，特别是在幅度信息与运动启动之间的短时间间隔内存在串扰。这与以下观点一致，即幅度设定的并发过程之间的串扰是短暂的，并且随着运动编程可用时间的增加而消失。
