New evidence on the suggestibility of memory: the role of retrieval-induced forgetting in misinformation effects.
Extending recent work that has demonstrated that the act of remembering can result in the inhibition of related items in memory, the present research examined whether retrieval-induced forgetting could provide a mechanism for explaining misinformation effects. Specifically, the authors found in their first study that the inhibition of critical items rendered the recollection of postevent information more likely in a subsequent test of memory. The authors established in their second study that when guided retrieval practice and final recall tests were separated by 24 hr, retrieval-induced forgetting failed to emerge and misinformation effects were absent. In contrast, a delay of 24 hr between initial encoding and guided retrieval practice produced not only retrieval-induced forgetting but also misinformation effects.
