我们报告的两个实验表明，动态定位我们自己的脸有助于自动吸引注意力。我们让参与者完成一个提示任务，在这个任务中，他们必须判断一个被动态改变方向的中央脸所提示的侧边目标的方向。实验1显示，在长时间刺激启动异步（SOA）条件下，自我面孔和朋友面孔均产生可靠的提示效应，而在短时间刺激启动异步（SOA）条件下，自我面孔只产生空间提示效应。在实验2中，与面孔线索相关的事件相关电位（ERP）数据显示，相对于朋友面孔和陌生面孔，自我面孔的N1分量的振幅更大。相比之下，与朋友和不熟悉的其他线索相比，自我的P3分量的振幅有所降低。N1自我偏倚效应的大小与P3自我偏倚的强度相关。结果表明，面部朝向的动态变化可以为注意力提供强大的生态线索，增强感官反应（N1），减少决策过程中的不确定性（P3）。
We report two experiments showing that dynamically orienting our own face facilitates the automatic attraction of attention. We had participants complete a cueing task where they had to judge the orientation of a lateralized target cued by a central face that dynamically changed its orientation. Experiment 1 showed a reliable cueing effect from both self- and friend-faces at a long stimulus onset asynchrony (SOA), however, the self-faces exclusively generated a spatial cueing effect at a short SOA. In Experiment 2, event-related potential (ERP) data to the face cues showed larger amplitudes in the N1 component for self-faces relative to friend- and unfamiliar-faces. In contrast, the amplitude of the P3 component was reduced for self compared with friend- and unfamiliar-other cues. The size of the self-bias effect in N1 correlated with the strength of self-biases in P3. The results indicate that dynamic changes in the orientation of one’s own face can provide a strong ecological cue for attention, enhancing sensory responses (N1) and reducing any subsequent uncertainty (P3) in decision-making.
