In a spatial Stroop task, eye-gaze targets produce a reversed congruency effect (RCE) with faster responses when gaze direction and location are incongruent than congruent. On the other hand, non-social directional targets (e.g., arrows) elicit a spatial Stroop effect (SSE). The present study examined whether other social stimuli, such as head orientation, trigger the RCE. Participants judged the target direction of the head or the gaze while ignoring its location. While the gaze target replicated the RCE, the head target produced the SSE. Moreover, the head target facilitated the overall responses relative to the gaze target. These results suggest that the head, a salient directional feature, overrides the social significance. The RCE may be specific to gaze stimuli, not to social stimuli in general. The head and gaze information differentially affect our attentional mechanisms and enable us to bring about smooth social interactions.
在空间斯特鲁普任务中，当注视方向和位置不一致时，与一致时相比，眼动注视目标会产生反向一致性效应（RCE），反应更快。另一方面，非社会性方向目标（如箭头）会引发空间斯特鲁普效应（SSE）。本研究考察了其他社会刺激，如头部朝向，是否会引发RCE。参与者判断头部或注视的目标方向，同时忽略其位置。虽然注视目标重现了RCE，但头部目标产生了SSE。此外，相对于注视目标，头部目标促进了整体反应。这些结果表明，头部作为一个显著的方向特征，优先于社会意义。RCE可能特定于注视刺激，而不是一般的社会刺激。头部和注视信息对我们的注意力机制有不同的影响，并使我们能够实现顺畅的社会互动。
