Retrieval effort improves memory and metamemory in the face of misinformation

Retrieval demand, as implemented through test format and retrieval instructions, was varied across two misinformation experiments. Our goal was to examine whether increasing retrieval demand would improve the relationship between confidence and memory performance, and thereby reduce misinformation susceptibility. We hypothesized that improving the relationship between confidence and memory performance would improve controlled processes at retrieval. That is, when confidence and memory performance were well calibrated, participants would be able to withhold incorrect responses if given the opportunity. To examine the relationship between memory retention, confidence, and controlled withholding, we compared older and younger adults’ performance on a forced memory test, where participants could not withhold responses, and on a free test, where participants were encouraged to withhold responses. Confidence judgments were collected after forced responding. Retrieval demand was manipulated indirectly through type of test (cued recall vs. recognition) and directly through retrieval instructions. The results demonstrated that increasing retrieval demands improved memory retention, metamemorial monitoring and effective withholding. This was particularly pronounced when participants received misleading information. Finally, older adults required explicit direction to effectively monitor memory and institute successful controlled withholding.

► Would varying retrieval demands affect performance in the misinformation paradigm? ► We varied demand via type of test (cued recall vs. recognition) and instructions. ► We also compared younger and older adults. ► We used free and forced tests and recorded confidence to assess metamemorial accuracy. ► Increasing demand improved memory and metamemory in the misinformation paradigm.
