对12名精神分裂症患者和12名健康志愿者进行了面孔情绪和身份的选择性注意研究。患者和对照组都需要执行两个分类任务（根据身份或情绪）。使用了两个独立的身份（人A/人B）和情感（恐惧/愤怒）值。当分类任务在一个维度上时，另一个维度是相关的、恒定的或正交的（Garner WR.信息和结构的处理。Potomac，MD：Erlbaum，1974，Garner WR.概念和选择过程中刺激维度的相互作用。认知心理学1976;8：98123）。结果表明，患者和健康的参与者有一个不对称的模式的性能：他们能够有选择地参加的身份的脸，无论脸上表达的情绪，但身份的变化干扰面部情绪的分类。此外，相关研究表明，精神分裂症患者情绪分类的身份干扰与阴性症状的严重程度存在协变关系。在现有的面孔识别模型框架下，讨论了精神分裂症患者的选择性注意能力以及情绪和面孔识别的独立性假设。(C)2001爱思唯尔科技有限公司版权所有。
The selective attention to facial emotion and identity was investigated in 12 patients with schizophrenia and 12 healthy participants. Both patients and controls were required to perform two classification tasks (according either to identity or emotion). Two separate values for identity (person A/person B) and for emotion (fear/anger) were used. When the classification task was on one dimension, the other dimension was either correlated, constant, or orthogonal (Garner WR. The Processing of Information and Structure. Potomac, MD: Erlbaum, 1974, Garner WR. Interaction of stimulus dimensions in concept and choice processes. Cognitive Psychology 1976;8:98123). Results indicated that both patients and healthy participants had an asymmetrical pattern of performance: they were able to selectively attend to the identity of the face presented, regardless of the emotion expressed on the face, but variation in identity interfered with the classification of facial emotion. Moreover, a correlational study indicated that the identity interference on emotion classification for schizophrenic patients covaried with the severity of their negative symptoms. The selective attention competencies in schizophrenia and the independence hypothesis of emotion and face recognition are discussed in the framework of current face recognition models.
