Individuals with borderline personality disorder (BPD) frequently display impairments in the identification of emotional facial expressions paralleled by a negativity bias. However, it remains unclear whether misperception of facial expressions is a key psychopathological marker of BPD. To address this question, the authors examined 43 women diagnosed with BPD and 56 healthy female controls using an emotion face identification task and a face dot-probe task together with measures on psychopathology. Compared to controls, women with BPD showed impaired identification of disgusted and angry faces concurrent with a bias to misclassify faces as angry, and a faster preconscious vigilance for fearful relative to happy facial expressions. Increased severity of borderline symptoms and global psychopathology in BPD patients were associated with reduced ability to identify angry facial expressions and a stronger negativity bias to anger. The findings indicate that BPD patients who misperceive face emotions have the greatest mental health issues.
边缘型人格障碍（BPD）患者在识别情绪面部表情时经常存在障碍，同时伴有负性偏见。然而，目前尚不清楚面部表情的误解是否是 BPD 的一个关键心理病理学标记。为了解决这个问题，作者使用情绪面孔识别任务和面孔点探测任务以及心理病理学测量，对 43 名被诊断为 BPD 的女性和 56 名健康女性对照进行了研究。与对照组相比，BPD 女性在识别厌恶和愤怒表情方面存在障碍，同时更倾向于将表情错误地归类为愤怒，并且对恐惧表情的无意识警觉比对快乐表情更快。BPD 患者的边缘症状严重程度和总体心理健康状况与识别愤怒表情的能力下降以及对愤怒的负性偏见增强有关。研究结果表明，误解面部情绪的 BPD 患者存在最大的心理健康问题。
