Centrally presented gaze cues typically elicit a delayed inhibition of return (IOR) effect compared to peripheral exogenous cues. We investigated whether gaze cues elicit early onset IOR when presented peripherally. Faces were presented in the left or right peripheral hemifields, which then gazed upward or downward. A target appeared in one of four oblique spatial locations giving the cue and target horizontal or vertical congruency, both, or neither. After establishing that peripheral movement and gaze direction jointly facilitate target processing at short durations (200 ms: Experiment 1), IOR was evident for peripheral motion at longer time courses (800 and 2400 ms: Experiment 2). Only after 2400 ms did gaze direction additionally contribute to IOR for the specific gazed at location, showing the inverse pattern of response times to Experiment 1. The onset of IOR for gaze cues is independent from peripheral exogenous cueing but nevertheless contributes to the allocation of attention.
与外周的外源性线索相比，中央呈现的注视线索通常会引发延迟的返回抑制（IOR）效应。我们研究了注视线索在外周呈现时是否会引发早期的IOR。面孔呈现于左或右外周半视野，然后向上或向下注视。一个目标出现在四个倾斜空间位置之一，使线索和目标在水平或垂直方向上一致、两者都一致或两者都不一致。在确定外周运动和注视方向在短持续时间（200毫秒：实验1）内共同促进目标处理后，在外周运动较长时间进程（800和2400毫秒：实验2）时IOR明显。只有在2400毫秒后，注视方向才额外促成特定注视位置的IOR，呈现出与实验1相反的反应时间模式。注视线索的IOR起始独立于外周外源性线索提示，但仍有助于注意力的分配。
