Emotion strengthens the subjective experience of recollection. However, these vivid and confidently remembered emotional memories may not necessarily be more accurate. We investigated whether the subjective sense of recollection for negative stimuli is coupled with enhanced memory accuracy for contextual details using the remember/know paradigm. Our results indicate a double-dissociation between the subjective feeling of remembering, and the objective memory accuracy for details of negative and neutral scenes. “Remember” judgments were boosted for negative relative to neutral scenes. In contrast, memory for contextual details and associative binding was worse for negative compared to neutral scenes given a “remember” response. These findings show that the enhanced subjective recollective experience for negative stimuli does not reliably indicate greater objective recollection, at least of the details tested, and thus may be driven by a different mechanism than the subjective recollective experience for neutral stimuli.

In a simulated last-minute test preparation scenario, the authors examined the extent to which practice can influence accuracy of self-assessment, overall test performance, and memory of a familiar knowledge domain. They simulated test preparation by exposing students to practice questions, allegedly from a study guide. The test preparation consisted of either answering questions (retrieval practice) and then checking the correctness of the answers or reviewing questions along with their answers (review-only practice). Immediately after either form of practice, students took a test with questions whose content was conceptually related to the practice test questions. In this study, both forms of practice had a beneficial effect on self-assessment prior to the test and on overall test performance. When the authors examined specific memory responses, they found practice to benefit the frequency of correct responses that students defined as experiences of remembering and knowing. The effect of practice was not modulated by the recency of the acquisition of the domain being tested (at least within the time span of an academic semester).
