The Effects of Accuracy Motivation on Children's and Adults' Event Recall,Suggestibility, and Their Answers to Unanswerable Questions

This study investigated children's and adults' event recall accuracy and suggestibility effects when participants' accuracy motivation was manipulated. A total of 240 participants (6-, 7-, and 8-year-olds, and adults) were shown a video and later asked 4 types of questions: answerable questions, both open-ended and strongly misleading, and unanswerable questions, both open-ended and strongly misleading. Participants were either (a) rewarded with a token for every correct answer (high accuracy motivation, Free Report Plus Incentive condition), (b) explicitly given the option of answering with "don't know" when unsure (medium accuracy motivation, Free Report condition), or (c) asked to provide an answer to every question, even when they were not sure or had to guess or both (low accuracy motivation, Forced Report condition). The condition with the high accuracy motivation yielded the highest recall accuracy scores for answerable open-ended and misleading questions. For unanswerable questions, even the youngest age group was able to increase the number of appropriate "don't know" answers when highly motivated to be accurate, but a misleading question format undermined these abilities. The results highlight important interactions between social (accuracy motivation) and cognitive factors (metacognitive monitoring processes) in children's formal interviewing.
