研究了空间刺激-反应（S-R）兼容性对单手两指选择反应的影响。受试者必须对右视野或左视野中出现的闪光尽快做出反应。他们用左手或右手的食指或中指按下空间上相同（兼容）的键或空间上不同（不兼容）的键。在条件 1 中，受试者的手掌朝下（旋前）；在条件 2 中，他们的手掌朝上（旋后），因此手指的空间顺序颠倒了。在这两种情况下，都发现左右刺激场与空间左右手指之间存在很强的兼容性效应。兼容的反应时间比不兼容的反应时间在掌心向下的情况下短 52 毫秒，在掌心向上的情况下短 61 毫秒。结果被解释为支持空间兼容性的编码假设。
The influence of spatial stimulus-response (S-R) compatibility on unimanual two-finger choice reactions was investigated. Subjects had to react as fast as possible to a flash of light that was presented in the right or left visual field. They used the index or middle fingers of their left or right hands to press the spatially same (compatible) key or the spatially different (incompatible) key. In Condition 1 the subjects'' palms faced down (pronation); in Condition 2 their palms faced up (supination) so that the spatial order of the fingers was reversed. A strong compatibility effect between right and left field of stimulation and spatially right and left finger was found under both conditions. Compatible reaction times were shorter than incompatible reaction times by 52 msec in the palm-down condition and by 61 msec in the palm-up condition. The results are interpreted as supporting the coding hypothesis of spatial compatibility.
