研究表明，感知到的眼睛注视会导致观看者的空间注意力随之转向该注视方向。这里报告的两个实验研究了凝视者眼球运动的性质对这种定向效应的影响程度。在这些实验的每次试验中，参与者都被要求对一个目标做出快速反应，该目标可能出现在中央出现的面孔刚刚凝视的位置（有提示的目标）或不在凝视接收者的位置（无提示的目标）。凝视线索包括快速扫视眼球运动或较慢平滑的追踪运动。有线索的目标比无线索的目标的响应速度更快，并且当凝视无法预测目标位置（实验 1）和反预测目标位置（实验 2）时，这种凝视线索定向效应对于每种类型的凝视转移都是等效的。结果并没有支持运动速度调节凝视提示定向的假设。然而，他们确实表明，无论运动类型如何，眼睛本身的运动可能足以触发定向效应。
Research has established that a perceived eye gaze produces a concomitant shift in a viewer’s spatial attention in the direction of that gaze. The two experiments reported here investigate the extent to which the nature of the eye movement made by the gazer contributes to this orienting effect. On each trial in these experiments, participants were asked to make a speeded response to a target that could appear in a location toward which a centrally presented face had just gazed (a cued target) or in a location that was not the recipient of a gaze (an uncued target). The gaze cues consisted of either fast saccadic eye movements or slower smooth pursuit movements. Cued targets were responded to faster than uncued targets, and this gaze-cued orienting effect was found to be equivalent for each type of gaze shift both when the gazes were un-predictive of target location (Experiment 1) and counterpredictive of target location (Experiment 2). The results offer no support for the hypothesis that motion speed modulates gaze-cued orienting. However, they do suggest that motion of the eyes per se, regardless of the type of movement, may be sufficient to trigger an orienting effect.
