正常受试者被呈现一张简单的线条画，画的是一张看向左、右或正前方的脸。一个目标字母F或T然后出现在左边或右边的脸。所有受试者均参与了目标检测、定位和识别响应条件。虽然受试者被告知线条画的注视方向（线索）并不能预测目标会出现在哪里，但在所有三种情况下，当注视方向是朝向目标时，反应时间确实更快。这项研究提供了证据的隐蔽，反射性定向到周边地区的反应，在固定的无信息的目光转移。社会注意力和视觉定向的理论的影响进行了讨论，并认为这种现象可能背后的大脑机制。
Normal subjects were presented with a simple line drawing of a face looking left, right, or straight ahead. A target letter F or T then appeared to the left or the right of the face. All subjects participated in target detection, localization, and identification response conditions. Although subjects were told that the Line drawing's gaze direction (the cue) did not predict where the target would occur, response time in all three conditions was reliably faster when gaze was toward versus away from the target. This study provides evidence for covert, reflexive orienting to peripheral locations in response to uninformative gaze shifts presented at fixation. The implications for theories of social attention and visual orienting are discussed, and the brain mechanisms that may underlie this phenomenon are considered.
