表情図分類行動における精神分裂病者の認知

抄録

The purpose of this study was to investigate the perception of schizophrenics in classifying pictures of various facial expressions. Schizophrenics were divided into five groups according to the duration of their hospitalization. In the first experiment, subjects were instructed to look at the pictures of three different kinds of facial expressions, anger, delight (laughing) and sadness (crying), and classify them into any categories they like. In comparison with normals, schizophrenics had a difficulty in recognizing the differences in the various facial expressions. In the second experiment, subjects were instructed to look at the same pictures and classify them into three groups of different facial expressions. In this case, schizophrenics were able to classify them almost as well as normals.
