This study tested the hypothesis that interhemispheric communication about emotional stimuli is influenced by situational factors that alter emotional relevance. Under evaluative or nonevaluative conditions, participants matched angry and happy faces within a single visual field or across opposite visual fields. An overall across-field advantage (AFA) reflected the benefit of sharing information between the hemispheres. The AFA was greater for angry than for happy faces in the evaluation condition but did not differ for angry and happy faces in the no-evaluation condition. Examination of individual differences indicated that high trait evaluation levels of worry were associated with poorer interhemispheric communication of angry faces, supporting a threat-avoidance conception of worry. Thus, both situational factors and individual differences affected interhemispheric communication about emotional faces.
本研究检验了这样一个假设，即关于情绪刺激的半球间交流受改变情绪相关性的情境因素影响。在评价性或非评价性条件下，参与者在单个视野内或跨相对视野匹配愤怒和高兴的面孔。总体跨视野优势（AFA）反映了半球间共享信息的益处。在评价条件下，愤怒面孔的AFA比高兴面孔的更大，但在非评价条件下，愤怒和高兴面孔的AFA没有差异。对个体差异的检验表明，高特质担忧水平与愤怒面孔的半球间交流较差有关，这支持了担忧的威胁回避概念。因此，情境因素和个体差异都影响了关于情绪面孔的半球间交流。
