摘要:

恐惧情绪由于其具有威胁性而优先得到有效的加工。其中空间频率作为处理面孔信息的基础成分, 通过不同的神经通路影响恐惧面孔表情的加工。双通路观点认为在皮层下通路上, 低空间频率的恐惧面孔表情存在优先传递性, 高空间频率则主要通过皮层通路对恐惧面孔表情进行精细化加工; 而多通路则能够更加灵活地处理空间频率对情绪加工的影响。未来研究应明确脑区及其子区域在多条通路上的作用, 从而进一步验证视觉信息是如何影响情绪加工的。

Abstract:

Fear has been often given priority to effective processing for the need to evade threatening stimuli. Most of researches have probed the influence of high and low spatial frequencies on the processing of fearful faces from the perspective of the two-channel model. Low spatial frequency components of the fearful face can be processed preferentially in the subcortical pathway. The high spatial frequency mainly processes the fearful faces through the cortical pathway. On this basis, researchers have proposed multiple pathways. The purpose of this paper is to review the subcortical, cortical and multiple pathways from the physiological perspective, and then organize the effects that high/low spatial frequencies on the processing of fearful faces in the various pathways and propose the controversies. Finally, we suggested several focuses that could be studied in the future.

Key words: spatial frequency, fearful facial expression, subcortical pathway, cortical pathway, multiple pathways
