Research into facial emotion perception in schizophrenia has burgeoned over the past several decades. The evidence is mixed regarding whether patients with schizophrenia have a general facial emotion perception deficit (a deficit in facial emotion perception plus a more basic deficit in facial processing) or specific facial emotion perception deficits (deficits only in facial emotion perception tasks). A meta-analysis is conducted of 28 facial emotion perception studies that include control tasks. These studies use differential deficit designs to examine whether patients with schizophrenia demonstrate a general deficit or specific deficit in facial emotion perception. A significant mean effect size is found for total facial emotion perception (d=-0.85). Patients with schizophrenia demonstrate impaired ability to perform corresponding control tasks, and the mean effect size is -0.70. The current findings suggest that patients with schizophrenia have moderately to severely impaired perception of facial emotion.
在过去的几十年中，精神分裂症患者面部情绪感知的研究蓬勃发展。目前的证据表明，精神分裂症患者是否存在一般的面部情绪感知缺陷（面部情绪感知加上更基本的面部处理缺陷），还是存在特定的面部情绪感知缺陷（仅在面部情绪感知任务中存在缺陷）存在争议。对包括对照任务在内的 28 项面部情绪感知研究进行了荟萃分析。这些研究使用差异缺陷设计来检查精神分裂症患者是否在面部情绪感知方面表现出一般缺陷或特定缺陷。总面部情绪感知的平均效应量显著（d=-0.85）。精神分裂症患者在执行相应的对照任务时表现出较差的能力，平均效应量为-0.70。目前的研究结果表明，精神分裂症患者对面部情绪的感知能力受损较为严重。
