Recent evidence indicates that emotional stimuli may be accorded special priority in information processing. Extending that research, this study tested the hypothesis that communication between the left and right hemispheres would be facilitated for emotional compared to non-emotional faces. Sixty-eight participants matched angry, happy, and neutral face photographs either within a single visual field (i.e., within one hemisphere) or across opposite visual fields (i.e., between the two hemispheres). An overall performance advantage favoring across-field trials was modulated by the emotionality of the face. Specifically, the across-field advantage was significantly greater for angry and happy faces compared to neutral faces, a pattern evident for both accuracy and reaction time data. Possible interpretations of the enhanced interhemispheric processing advantage include increased computational complexity or subcortical transfer of emotionally salient information.
近期证据表明，在信息处理过程中，情绪刺激可能会被赋予特殊的优先级。在此研究基础上进行拓展，本研究检验了这样一个假设：相较于无表情的面孔，左右半球之间针对有表情的面孔的交流将更易实现。68名参与者在单一视野（即一个半球内）或相对视野（即两个半球之间）中匹配愤怒、开心和中性的面部照片。面部情绪调节了有利于跨视野试验的总体表现优势。具体而言，相较于中性面孔，愤怒和开心面孔的跨视野优势显著更大，这一模式在准确性和反应时间数据中均很明显。半球间加工优势增强的可能解释包括计算复杂性增加或情绪显著信息的皮层下传递。
