Abstract：
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.
摘要：
在空间Stroop任务中，当注视方向和位置不一致时，眼睛注视目标会产生相反的一致效应（RCE），其响应比一致快。另一方面,非社交定向目标(例如，箭头)引发空间Stroop效应(SSE)。本研究检查了其他社会刺激是否，比如头部方向，触发RCE。参与者判断头部或凝视的目标方向，而忽略其位置。当凝视目标复制RCE时，头部目标产生了SSE。此外，头部目标促进了相对于凝视目标的总体响应。这些结果表明，头部，一个显著的方向特征，超越社会意义。RCE可能特定于凝视刺激，不是一般的社会刺激。头部和凝视信息会不同地影响我们的注意机制，并使我们能够实现平稳的社交互动。
