面部表情的无意识识别开启了一种有趣的可能性，即两种情绪可以同时存在于一个大脑中，无意识和有意识的感知输入相互作用。我们调查了这种相互作用，在三个实验中使用的偏盲患者与残余无意识的视觉。在同时呈现面部表情的完整和盲目的领域，我们测量有意识和无意识识别的图像之间的相互作用。恐惧特异性一致性效应表现为梭状回、杏仁核和枕区神经元活动增强。无意识的面部表情也会影响有意识识别的情感声音的处理。视觉和听觉输入之间的情感一致性增强了盲人杏仁核和上级丘的活动，相对于完整的，现场介绍的面孔。我们的研究结果表明，对恐惧的识别是强制性的，独立于意识。最重要的是，无意识的恐惧识别仍然很强大，即使在观察者意识到的同时出现的不一致的快乐面部表情或情绪化的声音。
Nonconscious recognition of facial expressions opens an intriguing possibility that two emotions can be present together in one brain with unconsciously and consciously perceived inputs interacting. We investigated this interaction in three experiments by using a hemianope patient with residual nonconscious vision. During simultaneous presentation of facial expressions to the intact and the blind field, we measured interactions between conscious and nonconsciously recognized images. Fear-specific congruence effects were expressed as enhanced neuronal activity in fusiform gyrus, annygdala, and pulvinar. Nonconscious facial expressions also influenced processing of consciously recognized emotional voices. Emotional congruency between visual and an auditory input enhances activity in amygdala and superior colliculus for blind, relative to intact, field presentation of faces. Our findings indicate that recognition of fear is mandatory and independent of awareness. Most importantly, unconscious fear recognition remains robust even in the light of a concurrent incongruent happy facial expression or an emotional voice of which the observer is aware.
