Background and Objectives

Individuals with features of borderline personality disorder (BPD) are highly sensitive to social rejection. Working memory (WM) may play a critical role in processing emotional interpersonal information in BPD. Yet, little is known about how emotional WM operations are related to sensitivity to rejection cues and BPD features. Therefore, this study examined relationships among emotional WM operations, rejection sensitivity, and BPD features.

Methods

Participants with BPD features (n=39 with non-suicidal self-injury history; n=47 without non-suicidal self-injury history) and healthy participants (n=46) completed an emotional two-back task before and after a social exclusion induction (the Cyberball game). Results. Results showed that participants with BPD features were slower at discarding faces expressing anger and pain from WM compared to healthy individuals before the social exclusion induction. Participants with BPD features and a history of self-injury were also slower at entering happy faces into WM compared to the other participants. Moreover, across participants, slower WM discarding of angry and pain faces was associated with higher levels of rejection sensitivity. Finally, no group differences emerged with respect to WM entering and discarding operations for emotional faces in response to social exclusion.

Limitations

This study was conducted in a sample of undergraduate students and did not consider comorbidity with other forms of psychopathology.

Conclusions

These findings cast light on how emotional WM difficulties may be involved in how individuals with BPD process emotional interpersonal information.

边缘人格特征个体的情绪工作记忆更新

背景和目标

具有边缘型人格障碍 (BPD) 特征的个体对社会排斥高度敏感。工作记忆 (WM) 可能在处理 BPD 中的情绪人际信息方面发挥关键作用。然而，关于情绪 WM 操作与对拒绝线索和 BPD 特征的敏感性之间的关系知之甚少。因此，本研究检验了情绪 WM 操作、拒绝敏感性和 BPD 特征之间的关系。

方法

具有 BPD 特征的参与者（n=39 有非自杀性自伤史；n=47 没有非自杀性自伤史）和健康参与者（n=46）在社会排斥前后完成了情绪二背任务感应（网络球游戏）。结果。结果表明，与社会排斥诱导前的健康个体相比，具有 BPD 特征的参与者在丢弃表达来自 WM 的愤怒和痛苦的面孔方面较慢。与其他参与者相比，具有 BPD 特征和自伤史的参与者在将快乐面孔输入 WM 方面也较慢。此外，在参与者中，较慢的 WM 丢弃愤怒和痛苦的面孔与更高水平的拒绝敏感性相关。最后，

限制

这项研究是在本科生样本中进行的，没有考虑与其他形式的精神病理学共病。

结论

这些发现揭示了情绪 WM 困难可能与 BPD 个体如何处理情绪人际关系信息有关。
