Michaels reported a compatibility effect in which responses were fastest at the destination of a moving stimulus; she interpreted this "destination" compatibility effect in terms of catching actions "afforded" by the stimulus motion. The present study evaluated implications of the catching-affordance account and compared them with those of an account based on spatial coding of relative direction. The destination compatibility effect was obtained when the responses were keypresses rather that catching movements of a joystick and regardless of whether the stimulus expanded, contracted, or only changed location. This effect was a function of relative rather than absolute location of the responses. A similar compatibility effect was obtained when destinations were designated by static arrow stimuli. The results are inconsistent with the catching-affordance account and are best explained by the coding of relative direction.
迈克尔报告了一种兼容性效应，即对移动刺激目标的反应最快；她根据刺激运动“提供”的捕捉动作来解释这种“目标”兼容性效应。本研究评估了捕捉可供性解释的含义，并将其与基于相对方向空间编码的解释进行了比较。当反应是按键操作而非操纵杆的捕捉动作时，且无论刺激是扩大、缩小还是仅改变位置，都能获得目标兼容性效应。这种效应是反应相对位置而非绝对位置的函数。当目标由静态箭头刺激指定时，也能获得类似的兼容性效应。这些结果与捕捉可供性解释不一致，最好用相对方向编码来解释。
