Withholding an action plan in memory for later execution can delay execution of another action, if the actions share a similar (compatible) action feature (i.e., response hand). This phenomenon, termed compatibility interference (CI), was found for identity-based actions that do not require visual guidance. The authors examined whether CI can generalize to both identity-based and location-based actions that require visual guidance. Participants withheld a planned action based on the identity of a stimulus and then immediately executed a visually guided action (touch response) to a 2nd stimulus based on its color identity (Experiment 1), its spatial location (Experiment 2), or an intrinsic spatial location within an object (Experiment 3). Results showed CI for both left- and right-hand responses in Experiment 1. However, CI occurred for left- but not right-hand responses in Experiment 2 and 3. This suggests that CI can generalize to visually guided actions under cognitive control but not to actions that invoke automatic visual-control mechanisms where the left hemisphere may play a special role (C. Gonzalez, T. Ganel, & M. Goodale, 2006). The code occupation account for CI (G. Stoet & B. Hommel, 2002) is also discussed.
如果动作共享相似（兼容）的动作特征（即反应手），在记忆中保留一个行动计划以供稍后执行可能会延迟另一个动作的执行。这种现象被称为兼容性干扰（CI），在不需要视觉引导的基于身份的动作中被发现。作者研究了CI是否可以推广到需要视觉引导的基于身份和基于位置的动作。参与者根据刺激的身份保留一个计划好的动作，然后立即根据第二个刺激的颜色身份（实验1）、空间位置（实验2）或物体内的固有空间位置（实验3）对其执行视觉引导的动作（触摸反应）。结果在实验1中显示了左右手反应的CI。然而，在实验2和3中，CI仅出现在左手反应中，而右手反应中未出现。这表明CI可以推广到认知控制下的视觉引导动作，但不能推广到调用自动视觉控制机制的动作，在这种机制中左半球可能发挥特殊作用（C. 冈萨雷斯、T. 加内尔和M. 古德尔，2006年）。还讨论了CI的代码占用解释（G. 斯托特和B. 霍梅尔，2002年）。
