背景过度一般的类别记忆被认为是抑郁症的易感因素，然而，在自愿但不自愿的提取任务中，抑郁个体对类别记忆的提取增加了。本研究提出，在非自愿记忆任务中，在图式相关刺激的提示下，类别记忆增加，从而倾向于激活抑郁状态下的功能障碍和消极的自我图式。方法对27名烦躁不安、26名既往抑郁和27名健康对照受试者进行了一项测量非自愿记忆的警戒任务。受试者还回答了几个测量每个记忆特征(例如，诱发情绪)和功能失调的图式量表的问题。结果支持这样的假设，即焦虑症和既往抑郁组相对于健康对照组报告了更多与图式相关(特别是负面)刺激的无意识类别记忆。功能障碍图式得分与图式相关负性刺激后提取的无意识类别记忆数量呈正相关。对图式相关刺激的非自愿类别记忆与负性诱发情绪有关，烦躁不安的参与者对积极刺激有更多的负性情绪。讨论和结论这些结果表明，基于图式的非自愿类别记忆可能更容易受到抑郁持续和复发的影响。
BackgroundOvergeneral categoric memory is known as a vulnerability factor for depression, yet increased retrieval of categoric memories among depressed individuals has been observed in voluntary but not involuntary retrieval tasks. Here we propose that, increased categoric memory occurs during involuntary memory tasks when cued by schema-related stimuli, which tend to activate dysfunctional and negative self-schema in depression.MethodsA vigilance task measuring involuntary memory was administered to 27 dysphoric, 26 past depressed, and 27 healthy control participants. Participants also responded to several questions measuring each memory characteristic (e.g., evoked emotion) and a dysfunctional schema scale.ResultsResults supported the hypothesis that dysphoric and past depressed groups reported more involuntary categoric memories for schema-related (particularly negative) stimuli relative to a healthy control group. Dysfunctional schema score was positively correlated with the number of involuntary categoric memories retrieved following schema-related negative stimuli. Involuntary categoric memory for schema-related stimuli was related to negative evoked emotion, and dysphoric participants experienced more negative emotion in response to positive stimuli.Discussion and ConclusionThese findings suggest that schema-based involuntary categoric memory may be vulnerable to the persistence and relapse of depression.
