Abstract

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.
