Recent literature proposes that repeated checking increases familiarity with the material, making recollections less vivid and detailed and promoting distrust in memory. The aim of the current study is to investigate the possible underlying mechanisms of low confidence in memory.
The Padua Inventory-Washington State University Revision (PI-WSUR) was applied in a cohort of university students. Among the students who completed the PI-WSUR, 84 participants were selected and assigned to low Obsessive-Compulsive Symptomatology (OCS) group or high OCS group according to their PI-WSUR scores. An interactive computer animation was developed to test repeated checking behavior. Participants were randomly assigned to two experimental conditions: "Feedback condition" and "no feedback condition". The participants were all asked to carry out checking rituals on a virtual gas ring. However, half of the participants were given feedback indicating that checking activity was successful and complete and half of the participants were not.
While there was no significant difference in terms of memory accuracy, memory detail and memory vividness between feedback condition and no feedback condition, there was a significant difference in terms of memory confidence between two experimental groups.
Results are discussed in the light of a different explanation offering that the level of distinctiveness of recollections plays crucial role in memory distrust rather than the explanation of low confidence hypothesis.
近期文献提出，反复检查会增加对材料的熟悉度，使回忆变得不那么生动和详细，并引发对记忆的不信任。本研究的目的是探究记忆信心不足可能的潜在机制。
对一组大学生应用帕多瓦量表-华盛顿州立大学修订版（PI-WSUR）。在完成PI-WSUR的学生中，根据他们的PI-WSUR分数选择84名参与者，并将其分为低强迫症状组或高强迫症状组。开发了一个交互式计算机动画来测试反复检查行为。参与者被随机分配到两种实验条件：“反馈条件”和“无反馈条件”。所有参与者都被要求在虚拟燃气炉上进行检查仪式。然而，一半的参与者得到了检查活动成功且完成的反馈，另一半参与者则没有。
虽然反馈条件和无反馈条件在记忆准确性、记忆细节和记忆生动性方面没有显著差异，但两个实验组在记忆信心方面存在显著差异。
根据一种不同的解释对结果进行了讨论，即回忆的独特性水平在记忆不信任中起关键作用，而不是低信心假设的解释。
