以往的研究表明，抑郁个体在工作记忆（WM）中既难以脱离负面信息，又难以保持积极信息。本研究旨在探讨抑郁症患者在WM中保持消极内容的倾向和在WM中保持积极内容的困难是否是由于抑郁发作期间的消极情绪一致性效应，或者这些倾向是否在抑郁发作之外是明显的。那些从抑郁发作中恢复过来的人，从来没有混乱的控制，进行情绪0-back和2-back任务，旨在评估工作记忆中更新情绪内容的偏差。与先前研究中的抑郁个体类似，恢复抑郁的参与者比从未抑郁的参与者更快地脱离快乐刺激，更慢地脱离悲伤刺激。尽管一个抑郁症特定的发现，以恢复抑郁症的个人，本研究并没有测试是否确定的情绪更新的偏见预测长期复发或恢复。所获得的结果表明，脱离负面内容，并保持积极的内容在WM的能力下降代表一种特质样的认知风格，损害自适应情绪调节，并可能有助于抑郁症的复发性。
Previous research has demonstrated that depressed individuals have difficulty both disengaging from negative information and maintaining positive information in working memory (WM). The present study was conducted to examine whether the tendency for depressed individuals to maintain negative content in WM and to experience difficulties maintaining positive content in WM is due to negative mood (in)congruency effects during a depressive episode, or whether these tendencies are evident outside of a depressive episode. Individuals who had recovered from a depressive episode and never disordered controls performed emotion 0-back and 2-back tasks designed to assess biases in updating emotional content in working memory. Similar to currently depressed individuals in previous studies, recovered depressed participants disengaged from happy stimuli more quickly and from sad stimuli more slowly than did their never-depressed counterparts. Despite the extension of a depression-specific finding to recovered depressed individuals, the present study does not test whether the identified emotion updating biases predict long-term relapse or recovery. The obtained results suggest that a decreased ability to disengage from negative content and to maintain positive content in WM represents a trait-like cognitive style that impairs adaptive emotion regulation and may contribute to the recurrent nature of depression.
