Inhibition of return (IOR) refers to slowed reaction times (RTs) when a target appears in the same rather than a different location as a preceding stimulus. The present study tested the hypothesis that IOR reflects a motor bias rather than a perceptual deficit. Two signals (S1 and S2) were presented on each trial. These signals were peripheral onsets or central arrows. The responses required to S1 and S2 were, respectively, no response-manual, manual-manual, saccadic-manual, no response-saccadic, manual-saccadic, and saccadic-saccadic. Uniting perceptual and motor bias views of IOR, the results demonstrated inhibition for responding to (a) peripheral signals when the eyes remained fixed (slowed visual processing) and (b) both peripheral and central signals when the eyes moved (slowed motor production). However, the results also emphasized that the nature of IOR depends fundamentally on the response modality used to reveal its influence.
返回抑制（IOR）是指当目标出现在与先前刺激相同而非不同的位置时，反应时间（RTs）变慢。本研究检验了IOR反映运动偏向而非感知缺陷这一假设。每次试验呈现两个信号（S1和S2）。这些信号是外周起始点或中央箭头。对S1和S2所需的反应分别为无反应-手动、手动-手动、眼跳-手动、无反应-眼跳、手动-眼跳和眼跳-眼跳。综合IOR的感知和运动偏向观点，结果表明，当眼睛保持固定时，对（a）外周信号的反应受到抑制（视觉处理变慢），当眼睛移动时，对（b）外周和中央信号的反应均受到抑制（运动产生变慢）。然而，结果也强调，IOR的本质从根本上取决于用于揭示其影响的反应方式。
