The current study investigated the effects of misinformation on children's memory reports after practice with the logic‐of‐opposition instruction at time of test. Four‐ and 6‐year‐old children participated in a play event in Session 1. During a two‐week delay, parents presented their children with either misinformation or correct information about the play event. Prior to a memory interview in Session 2, some misled children were given a developmentally appropriate logic‐of‐opposition instruction to not report information provided by their parents. Results indicated that children were misled by the incorrect information, but that the logic‐of‐opposition instruction aided in the children's retrieval of the original memory, particularly for the 6‐year‐olds. Implications of the results for memory malleability and social demand effects in children are discussed. Copyright © 2015 John Wiley & Sons, Ltd.
