Previous studies demonstrated that observation of facial expressions can modulate threat detection while looking at neutral or emotion-related scenes. Similarly, stimuli presented outside conscious awareness could influence social judgments of neutral novel stimuli. The two-fold aim of this study was: i) to evaluate whether observation of seen emotional faces could affect the judgment of social interactions without contextual cues (visible prime condition), and ii) whether this effect could also emerge when the emotional faces were made not visible by means of continuous flash suppression (invisible prime condition). We found that both seen and unseen faces are able to affect the judgment of ambiguous social interactions although this effect was particularly evident when affective faces were clearly visible. The present findings supported the idea that both conscious and unconscious processing of emotional faces have an important role in modulating perceivers' affective state and their judgment of social interactions.

危险在旁观者的眼中：可见和不可见的情感面孔对社会交往判断的影响。

先前的研究表明，观察面部表情可以在观察中性或与情绪相关的场景时调节威胁检测。同样，存在于意识意识之外的刺激可能会影响对中性小说刺激的社会判断。本研究的双重目的是：i) 评估对所见情绪面孔的观察是否会影响没有上下文线索的社会互动的判断（可见的主要条件），以及 ii) 当情绪面孔出现时，这种影响是否也会出现通过连续闪光抑制（不可见的初始条件）使不可见。我们发现，可见和不可见的面孔都能够影响模糊社会互动的判断，尽管当情感面孔清晰可见时这种影响尤为明显。
