记忆缺陷假说被用来解释强迫症患者的重复行为，然而，大多数关于言语记忆的研究显示了不同的结果。这些研究主要通过包含或遗漏先前遇到的材料来评估记忆的准确性，而不是错误识别（即包含错误的材料）。我们评估了有强迫性洗涤症状（OC）的个体、无强迫症症状的抑郁和焦虑匹配个体（D/A）和非焦虑个体（NAC）的错误记忆和记忆过程。28名OC个体、28名D/A个体和29名NAC个体分别阅读OC-威胁相关情景、积极情景和中性情景，然后进行识别测试。错误地识别与编码相关的单词，但不是先前看到的，场景被归类为错误记忆。为了评估潜在的记忆过程，参与者完成了一项修改后的记忆/知道任务，以检查OC个体在与OC相关的错误记忆（如细菌）、积极记忆（如彩票）和中性记忆（如面包）的回忆清晰度上是否与其他个体不同。对于威胁的错误记忆，OC个体比D/A和NAC个体更多地使用“知道”。对于真实记忆，OC个体比NAC个体更多地使用“知道”，而D/A个体则不是。一般来说，对“知道”（即熟悉的感觉）和虚假威胁记忆的更大依赖，特别是在有OC症状的个体中，可能会增加对威胁相关材料的不确定感，这可能会导致强迫行为。
The memory deficit hypothesis has been used to explain the maintenance of repetitive behavior in individuals with obsessive–compulsive disorder, yet the majority of studies focusing on verbal memory show mixed results. These studies primarily evaluated memory accuracy via the inclusion or omission of previously encountered material, as opposed to false recognition (i.e., the inclusion of erroneous material). We evaluated false memories and memory processes in individuals with obsessive–compulsive washing symptoms (OC), individuals matched on depression and anxiety without OC symptoms (D/A), and in nonanxious individuals (NAC). Twenty-eight OC, 28 D/A, and 29 NAC individuals read OC-threat relevant, positive, and neutral scenarios and then performed a recognition test. Erroneous recognition of words associated to encoded, but not previously viewed, scenarios were classified as false memories. To evaluate processes underlying memory, participants completed a modified remember/know task to examine whether the OC individuals differed from the other individuals in recollective clarity for false memories of OC-relevant (e.g., germs), positive (e.g., lottery), and neutral (e.g., bread) material. The OC individuals used “know” more than the D/A and NAC individuals for false memories of threat. For veridical memories, the OC individuals used “know” more than the NAC, but not, D/A individuals. The greater reliance on “know” (i.e., feelings of familiarity) in general and false threat memories in particular in individuals with OC symptoms may add to feelings of uncertainty for threat-relevant material, which may contribute to compulsive behavior.
