在创伤后应激障碍患者中，重新经历症状（如闪回）的严重程度和数量表现出相当大的差异。对再体验症状的一种解释引起了泛化：具体地说，创伤记忆可能以这样一种方式存储，即仅仅模糊地类似于创伤事件的某些特征的中性刺激就足以触发记忆。如果是这样的话，那么具有较高水平的再体验症状的个体可能会表现出更大的泛化能力，即使在与创伤无关的情况下也是如此。在目前的研究中，获得等效性（AE）测试被用来评估114名退伍军人，谁是自我评估创伤后应激障碍（PTSD）症状和陈述性记忆测试的联想学习和概括。在控制了人口统计学变量、精神活性药物使用和初始学习之后，回归分析表明，再次经历PTSD症状的人数显著改善了泛化模型（β =-0.23），但对联想学习或陈述性记忆没有改善。研究结果支持了这样一种观点，即泛化与重新体验症状有关，不仅限于学习创伤事件，甚至可以出现在相对无害的基于计算机的学习任务中。
The severity and number of reexperiencing symptoms (e.g. flashbacks) show considerable variability across individuals with post-traumatic stress disorder. One interpretation of reexperiencing symptoms invokes generalization: specifically, the traumatic memory may be stored in such a way that neutral stimuli that only vaguely resemble some feature of the traumatic event are sufficient to trigger the memory. If this is the case, then individuals with higher levels of reexperiencing symptoms might show greater generalization, even in contexts unrelated to trauma. In the current study, an acquired equivalence (AE) test was used to assess associative learning and generalization in 114 veterans, who were self-assessed for posttraumatic stress disorder (PTSD) symptoms and given a test of declarative memory. After controlling for demographic variables, psychoactive medication use, and initial learning, regression analyses indicated that the number of PTSD reexperiencing symptoms significantly improved the model for generalization (β = −.23) but not associative learning or declarative memory. The results support the idea that generalization is linked to reexperiencing symptoms, is not limited to learning about traumatic events, and can emerge even in a relatively innocuous computer-based learning task.
