Defending and reducing belief in memories: An experimental laboratory analogue

When receiving disconfirmatory social feedback about recollected events, people sometimes defend and sometimes reduce their belief that the event genuinely occurred. To improve estimates of the rates of memory defense and reduction, and of the magnitude of the change in belief in occurrence that results, in the present studies we examined the effect of disconfirmatory social challenges made to correctly recalled memories for actions performed in the lab. Adult participants performed, imagined, or heard action statements and imagined some of the initial actions multiple times. One week later, they completed a source-monitoring test and rated the actions on belief in their occurrence, recollection, visual detail, vividness, and reexperiencing. Four of the correctly recalled performed actions were challenged either prior to making the ratings during the test (Study 1, N = 44) or after making initial ratings after completing the test, following which the ratings were taken again (Study 2, N = 85). Across both studies, challenges were associated with lower belief-in-occurrence and recollection ratings on average than for control items, and belief in occurrence was affected to a greater extent than recollective features. Challenges that occurred during the test produced more instances of defense, whereas challenges that occurred after the test produced more instances of reduction. A closer analysis showed that some participants always defended, some always reduced, and some both defended and reduced belief. Responses to the first challenge positively predicted the responses to subsequent challenges. In addition, the procedure in Study 2 produced a variety of types of nonbelieved memories.

Reflecting on how we remember the personal past: missing components in the study of memory appraisal and theoretical implications

The current paper offers a selective review of the study of memory appraisal, focusing on recollections of the personal past, with the goal to bring attention to a missing component in this study. To date, memory appraisal studies have concentrated on participants' assessments of the content of their personal recollections (e.g., their perceptual detail and story-like feel), including beliefs about the accuracy of that content. Participants' assessments of reflection processes accompanying their recollections (e.g., a sense of piecing-together recollection fragments) have yet to be extensively examined. The lack of information on process-based appraisals is related to prior studies' procedural constraints (e.g., kinds of cue prompts and their timing, minimal opportunities for reflection). Reasons for addressing this missing component provide the central themes of the paper. The reasons emerge from the analysis of autobiographical cueing studies, including integration of narrative research studies and autobiographical works. The analysis leads to suggestions for future research involving the use of personal narratives that are intended to address critiques of reconstruction accounts and unresolved questions in the study of memory appraisal.
