Four experiments are described in which 1 visual object (the target) was selected from another (the distractor) according to its color (Experiments 1, 2, and 4) or its relative location (Experiment 3) and then was classified according to a simple geometric property. Object classification was signaled as fast as possible by a precision or power grip response, and this grip was either compatible or incompatible with either object. When targets were selected by color, target-compatible grip responses were facilitated, but distractor-compatible grip responses were impaired. When targets were selected by location, similar results were obtained for target-compatible grip responses, but not distractor-compatible grip responses. These data are explained in terms of the involvement of action codes in object-level selection.
文中描述了四项实验，在这些实验中，一个视觉对象（目标）根据其颜色（实验1、2和4）或相对位置（实验3）从另一个对象（干扰项）中被挑选出来，然后根据一个简单的几何属性进行分类。对象分类通过精确抓握或力量抓握反应尽可能快地发出信号，并且这种抓握与任一对象要么兼容要么不兼容。当根据颜色选择目标时，与目标兼容的抓握反应得到促进，但与干扰项兼容的抓握反应受到损害。当根据位置选择目标时，与目标兼容的抓握反应获得了类似结果，但与干扰项兼容的抓握反应则不然。这些数据是根据动作编码在对象级选择中的参与情况来解释的。
