传统观点认为，非预测性外周线索产生双相反应时间（RT）模式：线索位置的早期易化，随后是该位置的RT延迟。后一种效应称为返回抑制（IOR）。在两个实验中，我们报告说，返回抑制发生在一个线索的位置远远早于以前认为的，这是不同的家庭注意定向。在实验1中，早期观察到IOR（即，50毫秒内）。在实验2中，这种早期IOR效应被证明发生在目标检测，但不用于目标识别。我们的结论是，以前未能观察到早期返回抑制在一个线索的位置可能是由于注意力被引导到线索的位置，从而“掩盖”返回抑制。
Conventional wisdom holds that a nonpredictive peripheral cue produces a biphasic response time (RT) pattern: early facilitation at the cued location, followed by an RT delay at that location. The latter effect is called inhibition of return (IOR). In two experiments, we report that IOR occurs at a cued location far earlier than was previously thought, and that it is distinct hom attentional orienting. In Experiment 1, IOR was observed early (i.e., within 50 msec) at the cued location, when the cue predicted that a detection target would occur at another location. In Experiment 2, this early IOR effect was demonstrated to occur for target detection, but not for target identification. We conclude that previous failures to observe early IOR at a cued location may have been due to attention being directed to the cued location and thus "masking" IOR.
