大多数研究精神分裂症患者情绪识别的研究都集中在面部表情上，而忽略了身体和声音的表达。此外，对精神分裂症的情感多感觉整合知之甚少。在第一个实验中，作者调查了识别静态，面部模糊，全身表情（工具，愤怒，恐惧和悲伤）的两个选择，被迫选择，同时匹配的任务在精神分裂症患者，非精神分裂症精神病患者的样本，和匹配的控制。在第二个实验中，动态的，面部模糊，全身的表情（恐惧和快乐），同时与一致或不一致的人类或动物的发声精神分裂症患者和控制。参与者被要求对身体表达的情绪进行分类，并忽略听觉信息。实验1的结果表明，在精神分裂症组和在较小程度上在非精神分裂症精神病组的情绪识别障碍，这对所有四个表达式。实验二的结果表明，精神分裂症患者比对照组更受听觉信息的影响，但只有当听觉信息包括人类的发声。这表明精神分裂症患者在识别全身表情方面受损，并且他们对来自同一来源的双峰刺激表现出异常的情感多感觉整合。
Most studies investigating emotion recognition in schizophrenia have focused on facial expressions and neglected bodily and vocal expressions. Furthermore, little is known about affective multisensory integration in schizophrenia. In the first experiment, the authors investigated recognition of static, face-blurred, whole-body expressions (instrumental, angry, fearful, and sad) with a two-alternative, forced-choice, simultaneous matching task in a sample of schizophrenia patients, nonschizophrenic psychotic patients, and matched controls. In the second experiment, dynamic, face-blurred, whole-body expressions (fearful and happy) were presented simultaneously with either congruent or incongruent human or animal vocalizations to schizophrenia patients and controls. Participants were instructed to categorize the emotion expressed by the body and to ignore the auditory information. The results of Experiment 1 show an emotion recognition impairment in the schizophrenia group and to a lesser extent in the nonschizophrenic psychosis group, and this for all four expressions. The findings of Experiment 2 show that schizophrenia patients are more influenced by the auditory information than controls, but only when the auditory information consists of human vocalizations. This shows that schizophrenia patients are impaired in recognizing whole-body expressions, and they show abnormal affective multisensory integration of bimodal stimuli originating from the same source.
