According to betrayal trauma theory, adult survivors of childhood sexual abuse (CSA) who were molested by their caretakers (e.g., a father) are especially likely to dissociate ("repress") their memories of abuse. Testing college students, some reporting CSA, DePrince and Freyd (2004) found that those scoring high on a dissociation questionnaire exhibited memory deficits for trauma words when they viewed these words under divided-attention conditions. Replicating DePrince and Freyd's procedure, we tested for memory deficits for trauma words relative to neutral words in adults reporting either continuous or recovered memories of CSA versus adults denying a history of CSA. A memory deficit for trauma words under divided attention was expected in the recovered-memory group. Results were inconsistent with this prediction, as all three groups exhibited better recall of trauma words than neutral words, irrespective of encoding conditions.
根据背叛创伤理论,童年遭受性虐待(CSA)的成年幸存者若被其照顾者(如父亲)骚扰,尤其容易解离(“压抑”)他们对虐待的记忆。在对大学生进行测试时,一些学生报告了童年遭受性虐待的经历,德普林斯和弗雷德(2004年)发现,那些在解离问卷上得分高的学生,在分心条件下观看创伤词汇时,对这些词汇表现出记忆缺陷。重复德普林斯和弗雷德的实验步骤,我们测试了报告持续或恢复的童年遭受性虐待记忆的成年人与否认有童年遭受性虐待历史的成年人相比,对创伤词汇相对于中性词汇的记忆缺陷。预计恢复记忆组在分心条件下对创伤词汇存在记忆缺陷。结果与这一预测不一致,因为所有三组对创伤词汇的回忆都比对中性词汇的回忆更好,无论编码条件如何。
