Emotion perception biases may precipitate problematic interpersonal interactions in families affected with borderline personality disorder (BPD) and lead to conflictual relationships. In the present study, the authors investigated the familial aggregation of facial emotion recognition biases for neutral, happy, sad, fearful, and angry expressions in probands with BPD (n = 89), first-degree biological relatives (n = 67), and healthy controls (n = 87). Relatives showed comparable accuracy and response times to controls in recognizing negative emotions in aggregate and most discrete emotions. For sad expressions, both probands and relatives displayed slower response latencies, and they were more likely than controls to perceive sad expressions as fearful. Nonpsychiatrically affected relatives were slower than controls in responding to negative emotional expressions in aggregate, and fearful and sad facial expressions more specifically. These findings uncover potential biases in perceiving sad and fearful facial expressions that may be transmitted in families affected with BPD.

受边缘型人格障碍影响的家庭的面部情绪感知。

在患有边缘型人格障碍 (BPD) 的家庭中，情绪感知偏差可能会导致有问题的人际交往，并导致关系冲突。在本研究中，作者调查了 BPD 先证者 (n = 89)、一级生物学亲属 (n = 67) 和健康对照（n = 87）。亲属在识别总体情绪和最离散情绪中的负面情绪方面表现出与对照组相当的准确性和响应时间。对于悲伤的表情，先证者和亲属都表现出较慢的反应潜伏期，他们比对照组更有可能将悲伤的表情视为恐惧。总体而言，未受精神病影响的亲属对负面情绪表达的反应比对照组慢，尤其是恐惧和悲伤的面部表情。这些发现揭示了在感知悲伤和恐惧的面部表情时可能存在的潜在偏见，这些面部表情可能会在患有 BPD 的家庭中传播。
