Research has recurrently shown that individuals with schizophrenia have impairments in emotional facial recognition and this deficit has been associated with aberrant visual scanning of the face. Because human beings have the ability to control the expression of emotion, the communication process becomes more complex. The goal of the current study was to conduct a systematic examination of the response pattern and perceptual-attentional processing in distinguishing smiles with the presence and absence of the Duchenne marker and symmetry and asymmetry of the activation in individuals with schizophrenia. Sixteen individuals diagnosed with schizophrenia and 16 control individuals were asked to judge whether the smiles were really happy or not. Individuals with schizophrenia produced fewer expected responses than controls in judging the symmetric non-Duchenne smile as not really happy. In addition, like their healthy counterparts, individuals with schizophrenia showed difficulty with the judgement of asymmetric Duchenne smiles. In addition to not being as sensitive to the cues, individuals with schizophrenia show differences in their viewing patterns. While the current study does not provide clear links between these viewing patterns and judgment responses, future research should explore other explanations, such as explicit knowledge, for the differences in results.
研究反复表明，精神分裂症患者的面部表情识别存在障碍，这种缺陷与面部异常视觉扫描有关。由于人类有能力控制情绪的表达，因此交流过程变得更加复杂。本研究的目的是系统地检查在存在和不存在杜兴氏肌营养不良症标记以及个体面部激活的对称性和不对称性的情况下，精神分裂症患者区分微笑的反应模式和感知注意处理。要求 16 名被诊断患有精神分裂症的个体和 16 名对照组个体判断微笑是否真的开心。与对照组相比，精神分裂症患者在判断对称非杜兴氏肌营养不良症微笑不真实时，产生的预期反应更少。此外，与他们健康的同龄人一样，精神分裂症患者在判断非对称杜兴氏肌营养不良症微笑时也存在困难。除了对这些线索不敏感之外，精神分裂症患者的观看模式也存在差异。虽然当前的研究并没有为这些观看模式和判断反应之间提供明确的联系，但未来的研究应该探索其他解释，例如明确的知识，以解释结果的差异。
