Inducing resistance to suggestibility in children.

Thirty 7-year-olds, 30 12-year-olds, and 39 adults were administered the Gudjonsson Suggestibility Scale, which consists of a story followed by 20 questions, 15 of which are misleading. After subjects were told that their answers were not all correct, the questions were readministered to look for “shifts.” Approximately half of the subjects in each age group had been warned that the questions were difficult or tricky and that they should only answer with what they confidently remembered. Results indicated that younger children recalled less of the story and were more likely to acquiesce to leading questions than older children and adults. Children also changed more of their answers upon the second questioning. Recall was negatively correlated with both acquiescence to leading questions and likelihood of changing answers, even within age groups. The warning significantly reduced the effect of misleading questions across all age groups.
