If Borderline Personality Disorder (BPD) is characterized by an underlying emotional sensitivity, individuals with this disorder would be expected to demonstrate accurate identification of emotional expressions at earlier stages of expression (i.e., lower thresholds of facial expressivity across all emotional valences). Twenty-one outpatient youth (aged 15-24 years) meeting 3 or more DSM-IV BPD criteria and 20 community-derived participants (aged 15-24 years) with no history of psychiatric problems were tested on a measure of emotional sensitivity, the Face Morph Task. In this test faces morph from neutral to each of the six basic emotional expressions. The BPD group showed no evidence of heightened sensitivity to emotional facial expressions compared to the community control group (all P>0.05 and effect sizes ranging from 0 to 0.6). They require comparable levels of emotional expressivity in order to correctly identify emotions. Therefore, emotional sensitivity might not be apparent early in the course of BPD. Rather, it might develop later in the course of the disorder or be present only in severe BPD.
如果边缘型人格障碍（BPD）的特征是潜在的情绪敏感性，那么患有这种障碍的人应该能够在表情的早期阶段准确识别情绪表达（即，所有情绪效价的面部表情表达的下限阈值）。21 名符合 3 项或更多 DSM-IV BPD 标准的门诊青少年（15-24 岁）和 20 名无精神病史的社区参与者（15-24 岁）接受了一项情绪敏感性测试，即面部形态任务。在这个测试中，脸从中性逐渐变成六种基本表情。与社区对照组相比，BPD 组没有表现出对情绪面部表情的敏感性增强的迹象（所有 P 值均>0.05，效应量范围为 0 至 0.6）。他们需要相当程度的表情表达才能正确识别情绪。因此，情绪敏感性可能在 BPD 的早期阶段并不明显。相反，它可能在疾病的后期发展，或者只存在于严重的 BPD 中。
