In their natural environment, organisms receive information through multiple sensory channels and these inputs from different sensory systems are routinely combined into integrated percepts. Previously, we reported that in a population of schizophrenics, deficits in audiovisual integration were observed for complex stimuli (auditory and visual syllables), but not for more simple ones (beeps and light flashes). Here, we investigated multisensory integration of emotional information in a group of schizophrenic patients. In Experiment 1, we found a reduced effect of an emotional voice on the categorization of a facial expression. In Experiment 2, the reverse test situation was presented, and, here, we observed an exaggerated effect of a face expression on the categorization of an emotional voice. Results are discussed in the light of current models of multisensory integration and their relevance for schizophrenia.
在自然环境中，生物体通过多种感官通道接收信息，并且来自不同感官系统的这些输入通常会被整合为综合感知。此前，我们报道过，在一群精神分裂症患者中，对于复杂刺激（听觉和视觉音节）观察到视听整合缺陷，但对于更简单的刺激（哔哔声和闪光）则未观察到。在此，我们研究了一组精神分裂症患者中情绪信息的多感官整合。在实验1中，我们发现情绪声音对面部表情分类的影响减弱。在实验2中，呈现了相反的测试情境，在此我们观察到面部表情对情绪声音分类的影响被夸大。根据当前的多感官整合模型及其与精神分裂症的相关性对结果进行了讨论。
