We investigated whether patients with Korsakjoff's Sybdrome (KS) would demonstrate a discrepancy between (low) autobiographical specificity and (high) sense of reliving. We invited 20 KS patients and 24 controls to retrieve personal memories. After memory retrieval, they were invited to rate subjective characteristics of their recall (e.g., reliving, travel in time, remembering, realness). Besides this rating, we analyzed memories objectively with regard to specificity. Analysis demonstrated poorer sense of reliving and memory specificity in KS patients than in controls. Critically, a discrepancy (i.e., higher level of sense of reliving than of specificity) was observed in KS participants but not in controls. We propose a hypothesis of "genuine consciousness experience" in which the discrepancy between sense of reliving and specificity mirrors how KS patients can benefit from an authentic experience of the past despite compromise in their autobiographical recall.
我们研究了患有科萨科夫综合征(KS)的患者是否会在(低)自传体记忆特异性与(高)重温感之间表现出差异。我们邀请了20名KS患者和24名对照者回忆个人记忆。在记忆检索后,邀请他们对回忆的主观特征(如重温、时光穿梭、记忆、真实感)进行评分。除了这种评分外,我们还从特异性方面对记忆进行了客观分析。分析表明,KS患者的重温感和记忆特异性比对照组差。关键的是,在KS参与者中观察到了差异(即重温感水平高于特异性水平),而在对照组中未观察到。我们提出了一个“真实意识体验”的假说,其中重温感与特异性之间的差异反映了KS患者尽管自传体记忆受损,但仍能从对过去的真实体验中受益的方式。
