面部情绪感知的缺陷与精神分裂症患者的不良功能结局有关。然而，异常情绪感知和功能结果之间的关系仍然知之甚少。为了更好地了解精神分裂症患者面部情绪感知缺陷的性质，我们使用气泡面部情绪感知任务来识别精神分裂症患者（n = 20）和对照组（n = 20）在区分愤怒和中性面部表情时使用视觉面部信息的差异。正如假设的那样，精神分裂症患者需要比对照组更多的面部信息来准确区分愤怒和中性面部表情，并且他们依赖于不同的面部特征和空间频率来区分这些面部表情。具体来说，精神分裂症患者未充分利用眼睛区域，过度利用鼻子和嘴巴区域，并且几乎忽略了以最低空间频率水平呈现的信息。此外，事后单尾t检验显示，从“正常”的视觉面部信息的使用在眼睛区域和较低的整体社会功能的发散程度之间的正相关关系的适度强度。这些研究结果提供了直接支持精神分裂症患者在区分社会显着的情绪状态的视觉面部信息使用的异常模式。
Deficits in facial emotion perception have been linked to poorer functional outcome in schizophrenia. However, the relationship between abnormal emotion perception and functional outcome remains poorly understood. To better understand the nature of facial emotion perception deficits in schizophrenia, we used the Bubbles Facial Emotion Perception Task to identify differences in usage of visual facial information in schizophrenia patients (n = 20) and controls (n = 20), when differentiating between angry and neutral facial expressions. As hypothesized, schizophrenia patients required more facial information than controls to accurately differentiate between angry and neutral facial expressions, and they relied on different facial features and spatial frequencies to differentiate these facial expressions. Specifically, schizophrenia patients underutilized the eye regions, overutilized the nose and mouth regions, and virtually ignored information presented at the lowest levels of spatial frequency. In addition, a post hoc one-tailed t test revealed a positive relationship of moderate strength between the degree of divergence from "normal" visual facial information usage in the eye region and lower overall social functioning. These findings provide direct support for aberrant patterns of visual facial information usage in schizophrenia in differentiating between socially salient emotional states.
