Ideomotor theory is one variation of the general position that perception and motor action are related. According to this theory, a perceptual representation of the goal of a response must be generated prior to response initiation. Ideomotor theory can be extended by assuming that generation of this representation, which usually is required prior to motor action, is not needed if the stimulus itself corresponds to the response goal, that is, if the stimulus and response are ideomotor compatible. Because processing to generate the response representation is not needed with ideomotor compatibility, it should be possible to control two responses simultaneously without mutual interference if at least one stimulus-response relation is ideomotor compatible. Although supported in previous work involving discrete responses, this prediction of perfect time-sharing was found not to hold in the experiments reported here. These experiments, unlike those showing perfect time-sharing, involved continuous responses. We propose an alternative version of ideomotor compatibility, in which perfect time-sharing can occur if an integrated stimulus is provided to match the continuous and integrated response.
观念运动理论是感知与运动行为相关这一普遍观点的一种变体。根据该理论，在反应开始之前，必须生成反应目标的感知表征。如果刺激本身与反应目标相对应，即如果刺激与反应在观念运动上是兼容的，那么观念运动理论可以通过假设通常在运动行为之前所需的这种表征的生成是不需要的来加以扩展。由于在观念运动兼容性情况下不需要进行生成反应表征的处理，所以如果至少有一个刺激 - 反应关系在观念运动上是兼容的，那么应该有可能同时控制两种反应而互不干扰。尽管在先前涉及离散反应的研究中得到了支持，但在此处报告的实验中发现这种完美分时的预测并不成立。与那些显示完美分时的实验不同，这些实验涉及连续反应。我们提出了观念运动兼容性的另一种版本，其中如果提供一个综合刺激以匹配连续且综合的反应，就可以出现完美分时。
