23 名急性精神分裂症患者、21 名急性重度抑郁症患者（研究诊断标准）和 15 名正常对照者参与了一项关于面部表情和情绪面部识别的研究。在临床条件下，根据阴性症状评估量表的情感平坦部分评估自发面部表情。在实验实验室条件下，将非自愿（引发情绪的访谈）和自愿的面部表情（模仿和模拟六种基本情绪）记录在录像带上，从中获得基于评分者的面部活动强度或正确性分析。还在实验条件下使用相同的刺激材料评估了情感面部识别。所有受试者均接受两次评估（4 周内），控制患者组精神病理状态的变化。在精神分裂症患者中，抗精神病药物的影响是通过随机分配氟哌啶醇或哌嗪治疗来控制的。主要发现是精神分裂症和抑郁症患者的特征是情感相关功能障碍的定量、定性和时间模式不同。特别是，精神分裂症患者在情感识别以及自发和自愿的面部活动方面表现出类似特征的缺陷，无论药物、药物类型和剂量或锥体外系副作用如何。在抑郁症患者中，只有在情绪引发的访谈条件下他们的非自愿表达才能证明稳定的缺陷，而在急性期后，他们的自愿表达的减少变得明显。情感相关行为缺陷模式的差异可能反映了不同潜在心理生物系统的功能障碍。
Twenty-three acute schizophrenics, 21 acute major depressives (Research Diagnostic Criteria), and 15 normal controls participated in a study on facial expression and emotional face recognition. Under clinical conditions, spontaneous facial expression was assessed according to the affective flattening section of the Scale for the Assessment of Negative Symptoms. Under experimental laboratory conditions involuntary (emotion-eliciting inter-view) and voluntary facial expression (imitation and simulation of six basic emotions) were recorded on videotape, from which a raterbased analysis of intensity or correctness of facial activity was obtained. Emotional face recognition was also assessed under experimental conditions using the same stimulus material. All subjects were assessed twice (within 4 weeks), controlling for change of the psychopathological status in the patient groups. In schizophrenics, neuroleptic drug influence was controlled by random allocation to treatment with either haloperidol or perazine. The main findings were that schizophrenics and depressives are characterized by different quantitative, qualitative, and temporal patterns of affect-related dysfunctions. In particular, schizophrenics demonstrated a trait-like deficit in affect recognition and in their spontaneous and voluntary facial activity, irrespective of medication, drug type and dosage, or extrapyramidal side-effects. In depressives a stable deficit could be demonstrated only in their involuntary expression under emotion-eliciting interview conditions, whereas in the postacute phase a reduction in their voluntary expression became apparent. Differences in patterns of affect-related behavioral deficits may reflect dysfunctions in different underlying psychobiological systems.
