This study aimed to evaluate the ability to decode emotion in the auditory and audiovisual modality in a group of patients with schizophrenia, and to explore the role of cognition and psychopathology in affecting these emotion recognition abilities. Ninety-four outpatients in a stable phase and 51 healthy subjects were recruited. Patients were assessed through a psychiatric evaluation and a wide neuropsychological battery. All subjects completed the comprehensive affect testing system (CATS), a group of computerized tests designed to evaluate emotion perception abilities. With respect to the controls, patients were not impaired in the CATS tasks involving discrimination of nonemotional prosody, naming of emotional stimuli expressed by voice and judging the emotional content of a sentence, whereas they showed a specific impairment in decoding emotion in a conflicting auditory condition and in the multichannel modality. Prosody impairment was affected by executive functions, attention and negative symptoms, while deficit in multisensory emotion recognition was affected by executive functions and negative symptoms. These emotion recognition deficits, rather than being associated purely with emotion perception disturbances in schizophrenia, are affected by core symptoms of the illness.
本研究旨在评估一组精神分裂症患者在听觉和视听模式下解码情绪的能力，并探讨认知和精神病理学在影响这些情绪识别能力中的作用。招募了 94 名稳定期门诊患者和 51 名健康受试者。通过精神病学评估和广泛的神经心理学测试对患者进行评估。所有受试者均完成了综合情感测试系统（CATS），这是一组旨在评估情感感知能力的计算机化测试。与对照组相比，患者在不涉及非情感韵律辨别、语音表达情感刺激的命名以及判断句子情感内容的 CATS 任务中不受损害，而在听觉冲突条件和多通道模式下表现出特定的情绪解码障碍。韵律障碍受执行功能、注意力和阴性症状影响，而多感官情绪识别缺陷受执行功能和阴性症状影响。这些情绪识别缺陷与精神分裂症中纯粹的情绪感知障碍有关，而是受疾病的核心症状影响。
