Rumination in depressed adults is associated with a bias toward retaining negative information in working memory. We developed a task designed to modify this cognitive bias by having subjects repeatedly practice removing negative words from working memory, thereby enabling them to retain positive and neutral words. To assess the efficacy of this task, we recruited 60 adults who reported elevated repetitive negative thought (RNT) and randomly assigned them to receive a single administration of either the working memory bias modification (WMBM) task or a control task. Subjects in the WMBM condition exhibited greater reduction in proactive interference for negative information than did those in the control condition. These results suggest that the WMBM task reduces biased retention of negative information in working memory and, thus, may be useful in investigating the possible causal role of this cognitive bias in RNT or depression.
抑郁成年人的反刍思维与工作记忆中保留负面信息的偏向有关。我们开发了一项任务，旨在通过让受试者反复练习从工作记忆中去除负面词汇来改变这种认知偏向，从而使他们能够保留正面和中性词汇。为了评估这项任务的效果，我们招募了60名报告重复性消极思维（RNT）水平较高的成年人，并将他们随机分配接受单次工作记忆偏向修正（WMBM）任务或对照任务。与对照条件下的受试者相比，WMBM条件下的受试者对负面信息的前摄干扰减少得更多。这些结果表明，WMBM任务减少了工作记忆中负面信息的偏向性保留，因此，可能有助于研究这种认知偏向在RNT或抑郁症中可能的因果作用。
