It is widely assumed that processing of gaze direction occurs "automatically," in the sense that it is reflexive (unfolds in the absence of intention). We assessed this view in a task in which participants saw a schematic face in which the eyes were gazing left or right, along with a second directional target (an arrow in Experiment 1; a directional word in Experiment 2). The eyes and other directional target were sometimes congruent and other times incongruent. On each trial, participants were cued with a tone to respond to either the direction the eyes were gazing, or the direction the noneye target indicated. The time between the onset of the task cue and the onset of the face was manipulated so that on half the trials the face and the cue were presented at the same time. Regardless of the type of target, the congruency effect was the same size at the zero SOA as it was at the 750 SOA, suggesting that eyes were not processed until participants knew what task to perform. These results are consistent with the claim that processing of gaze direction is, at least some of the time, secondary to an intent (i.e., it is not reflexive).
人们普遍认为,注视方向的处理是“自动”进行的,也就是说它是反射性的(在没有意图的情况下展开)。我们在一项任务中评估了这一观点,在该任务中,参与者看到一张示意性的脸,眼睛向左或向右注视,同时还有第二个方向目标(实验1中的箭头;实验2中的方向词)。眼睛和其他方向目标有时一致,有时不一致。在每次试验中,参与者会听到一个提示音,要求他们对眼睛注视的方向或非眼睛目标指示的方向做出反应。任务提示音开始和脸出现之间的时间被操纵,以便在一半的试验中,脸和提示音同时呈现。无论目标类型如何,零刺激呈现间隔(SOA)时的一致性效应与750毫秒SOA时的一致性效应大小相同,这表明在参与者知道要执行什么任务之前,眼睛并没有被处理。这些结果与以下观点一致,即注视方向的处理至少在某些时候是次于意图的(即它不是反射性的)。
