快速评估生态相关的刺激可能会导致他们优先获得认识。连续闪光抑制允许在刺激由于相对于静态图像的动态噪声的强烈抑制性质而变得不可见的条件下评估情感处理。作者调查了恐惧的表情是否比中性或快乐的表情更快地从压抑中出现。恐惧的面孔总是比中性或快乐的面孔更快被检测到。对倒置面孔的反应比对紧张面孔的反应慢，但表现出相同的情绪表达效果，这表明倒置面孔中的一些关键特征仍然突出。当使用仅代表眼睛的刺激时，检测恐惧的类似偏见出现了，暗示了来自眼睛的信息在恐惧表情的前意识处理中的重要性。
Rapid evaluation of ecologically relevant stimuli may lead to their preferential access to awareness. Continuous flash suppression allows assessment of affective processing under conditions in which stimuli have been rendered invisible due to the strongly suppressive nature of dynamic noise relative to static images. The authors investigated whether fearful expressions emerge from suppression into awareness more quickly than images of neutral or happy expressions. Fearful faces were consistently detected faster than neutral or happy faces. Responses to inverted faces were slower than those to uptight faces but showed the same effect of emotional expression, suggesting that some key feature or features in the inverted faces remained salient. When using stimuli solely representing the eyes, a similar bias for detecting fear emerged, implicating the importance of information from the eyes in the preconscious processing of fear expressions.
