A deficit in the recognition of facial affect has been well documented in people with schizophrenia. Our 1995 research with normal subjects showed that hemispheric bias for processing facial affect is related to accuracy of recognition of facial affect. We tested whether this relationship holds in a sample of 25 people with schizophrenia who completed tasks of identification of facial affect and chimeric facial affect. Subjects with a left visual-field bias were significantly more accurate in identifying one facial emotion (sad) than were other subjects. Individual differences in hemispheric advantage for processing affect appears to be an important variable related to functional brain capacity within different populations.
面部情感识别缺陷在精神分裂症患者中已有充分记录。我们1995年对正常受试者的研究表明，处理面部情感的半球偏向与面部情感识别的准确性有关。我们测试了这种关系在25名精神分裂症患者样本中是否成立，这些患者完成了面部情感识别和嵌合面部情感识别任务。左视野偏向的受试者在识别一种面部情绪（悲伤）时比其他受试者明显更准确。处理情感的半球优势的个体差异似乎是与不同人群中功能性脑容量相关的一个重要变量。
