We may not believe what our memory tells us: Memory may deliver a compelling recollection we believe did not happen (we know we were not there at the time); and we may know an event happened that we fail to remember (even for when we were not drunk!). That is, there can be distrust in remembering and distrust in forgetting. Previous work by the authors has looked at this through a signal detection lens, reporting in separate studies that people who have distrust in remembering have either a high or low criterion for saying "old" (Zhang et al, 2023, 2024a). A plausible explanation for these contrasting results is that the criterion can either be the means by which false memories are generated enabling the distrust (low criterion); or rather, in conditions where accuracy is at stake, the means for compensating for the distrust (high criterion).

 

In the current study by Zhang et al (2024b), participants will be incentivised to be as accurate as possible, and in a memory test given feedback about commission errors or, in another group, ommission errors. As a manipulation check, the authors will test that the feedback increases distrust in remembering or distrust in forgetting, respectively, compared to a no feedback control group. Crucially, the authors hypothesize that people will adjust the criterion to say "old" in a compensatory way in each group. The study uses inference by intervals to provide a fairly severe test of this hypothesis.

 

The Stage 1 manuscript was evaluated over multiple rounds of in-depth review. Based on detailed responses to the reviewers' and recommender's comments, the recommender judged that the manuscript met the Stage 1 criteria and awarded in-principle acceptance (IPA).
