背景从面部表情中解码情感信息的能力对于成功的社交互动至关重要。边缘型人格障碍（BPD）是一种以人际关系和情绪功能为主要特征的人格障碍。关于BPD中面部情绪识别的实证研究很少发表，结果不一致。为了更准确地描述BPD的情绪识别缺陷，本研究实施了两个不同反应形式的情绪识别任务。19例BPD患者和19名健康受试者被要求评估视觉呈现的刺激（情感和中性面孔）的情感内容。第一项任务，恐惧愤怒中性（FAN）测试，需要快速区分负面或中性的面部表情，而在第二项任务中，情绪识别（ER）测试，关于默认情绪（悲伤，快乐，愤怒，恐惧和中性）的精确决定必须在没有时间限制的情况下实现。与健康受试者相比，BPD患者仅在快速辨别负面和中性面部表情（FAN测试）中表现出情感识别缺陷。与早期的发现一致，患者在评估中性面部表情时表现出负偏差。当处理时间不受限制时（ER测试），BPD患者在识别特定情绪方面表现得与健康受试者一样好。此外，快速辨别任务（FAN测试）的表现与创伤后应激障碍（PTSD）共病率之间存在相关性。我们的数据表明，BPD患者在快速和直接辨别负面和中性情绪表达方面存在选择性缺陷，这可能是社会交往困难的基础。
Background. The ability to decode emotional information from facial expressions is crucial for successful social interaction. Borderline personality disorder (BPD) is characterized by serious problems in interpersonal relationship, and emotional functioning. Empirical research on facial emotion recognition in BPD has been sparsely published and results are inconsistent. To specify emotion recognition deficits in BPD more closely, the present study implemented two emotion recognition tasks differing in response format.Method. Nineteen patients with BPD and 19 healthy subjects were asked to evaluate the emotional content of visually presented Stimuli (emotional and neutral faces). The first task, the Fear Anger Neutral (FAN) Test, required a rapid discrimination between negative or neutral facial expressions whereas in the second task, the Emotion Recognition (ER) Test, a precise decision regarding default emotions (sadness, happiness, anger, fear and neutral) had to be achieved without a time limit.Results. In comparison to healthy Subjects, BPD patients showed a deficit in emotion recognition only in the fast discrimination of negative and neutral facial expressions (FAN Test). Consistent with earlier findings, patients demonstrated a negative bias in the evaluation of neutral facial expressions. When processing time was unlimited (ER Test), BPD patients performed as well as healthy subjects in the recognition of specific emotions. In addition, an association between performance in the fast discrimination task (FAN Test) and post-traumatic stress disorder (PTSD) co-morbidity was indicated.Conclusions. Our data Suggest a selective deficit of BPD patients in rapid and direct discrimination of negative and neutral emotional expressions that may underlie difficulties in social interactions.
