This study distinguishes interpersonal trust learning with a novel trust learning paradigm in participants high (H-BPD) and low (L-BPD) in BPD features. Neutral faces were paired with trust-relevant behaviors in four conditions: trustworthy, untrustworthy, ambiguously trustworthy, and mixed trustworthiness. After training, participants rated faces on untrustworthiness as electroencephalographic measures were recorded. H-BPD rated neutral faces as significantly more untrustworthy than L-BPD at both time periods. Negative and ambiguous trustworthiness pairing conditions led to higher ratings of untrustworthiness, whereas trustworthy and mixed descriptors led to lower ratings of untrustworthiness. Learning enhanced the amplitude of an early sensory event-related potential (ERP) component (i.e., P1) for both groups. The slow-wave ERP, an index of sustained attention, revealed greater focus after learning to trustworthy descriptors in H-BPD and to untrustworthy descriptors in L-BPD. H-BPD utilized greater effort to overcome an inherent mistrust bias and L-BPD to overcome unexpected untrustworthy information.
本研究采用一种新颖的信任学习范式，区分了边缘型人格障碍（BPD）特征高（H-BPD）和低（L-BPD）的参与者的人际信任学习。在四种条件下，中性面孔与信任相关行为配对：可信赖、不可信赖、模糊可信赖和混合可信赖。训练后，参与者对面孔的不可信赖程度进行评分，同时记录脑电图测量数据。在两个时间段，H-BPD对中性面孔的不可信赖程度评分均显著高于L-BPD。消极和模糊的可信赖性配对条件导致更高的不可信赖程度评分，而可信赖和混合描述则导致更低的不可信赖程度评分。学习增强了两组早期感觉事件相关电位（ERP）成分（即P1）的幅度。慢波ERP是持续注意力的指标，显示在学习后，H-BPD对可信赖描述符、L-BPD对不可信赖描述符有更大的注意力集中。H-BPD需要付出更大努力来克服固有的不信任偏见，而L-BPD则要克服意外的不可信赖信息。
