Since Kraepelin called dementia praecox what we nowadays call schizophrenia, cognitive dysfunction has been regarded as central to its psychopathological profile. Disturbed experience and integration of emotions are, both intuitively and experimentally, likely to be intermediates between basic, non-social cognitive disturbances and functional outcome in schizophrenia. While a number of studies have consistently proven that, as part of social cognition, recognition of emotional faces and voices is disturbed in schizophrenics, studies on multisensory integration of facial and vocal affect are rare. We investigated audiovisual integration of emotional faces and voices in three groups: schizophrenic patients, non-schizophrenic psychosis patients and mentally healthy controls, all diagnosed by means of the Schedules of Clinical Assessment in Neuropsychiatry (SCAN 2.1). We found diminished crossmodal influence of emotional faces on emotional voice categorization in schizophrenics, but not in non-schizophrenia psychosis patients. Results are discussed in the perspective of recent theories on multisensory integration.
自从克雷佩林将早发性痴呆（即我们现在所说的精神分裂症）命名以来，认知功能障碍就一直被视为其精神病理学特征的核心。无论是从直觉上还是实验上看，情感体验和整合的紊乱都可能是精神分裂症中基本的非社会性认知障碍与功能结果之间的中介。虽然许多研究一直证明，作为社会认知的一部分，精神分裂症患者识别情感面孔和声音的能力受到干扰，但关于面部和声音情感的多感官整合的研究却很少。我们通过神经精神病学临床评估量表（SCAN 2.1）对三组人群进行了研究：精神分裂症患者、非精神分裂症性精神病患者和心理健康对照组，调查了情感面孔和声音的视听整合情况。我们发现，情感面孔对精神分裂症患者情感声音分类的跨模态影响减弱，而非精神分裂症性精神病患者则没有这种情况。我们从最近关于多感官整合的理论角度对结果进行了讨论。
