Differences Between True and False Memories Using the Criteria-Based Content Analysis

Although not designed for distinguishing true and false memories, several reasons argue for differences in the criteria-based content analysis (CBCA). As, to the best of our knowledge, previous research did not ensure a comparison between true and false memories, this study sought to do so. Memory reports of 52 participants were rated employing the CBCA by two independent raters. Analyses were based on event reports rated as a memory (where participants believed that the event had occurred and reported additionally remembered details about it) or reports rated as a belief (where participants believed that the event had occurred without remembering details about it). For both samples, the CBCA total score was significantly higher for true than false reports. Exploratory discriminant analyses revealed accuracy rates of 61.3%-69.6% and additional analyses hint towards the cognitive (vs. motivational) criteria as the main drivers of the obtained differences. Further replications are needed.
