Eyewitness memory, suggestibility, and repeated recall sessions in children with mild and moderate intellectual disabilities.

Abstract

This study of eyewitness memory questioned children with mild and moderate intellectual disabilities (ID) about a live staged event 1 day later and, again, 2 weeks later. Children with mild ID performed as well as typically-developing children of the same age in response to free recall instructions, and they were just as able as same age peers to resist misleading questions. However, they performed more poorly on general questions, probing for further information after free recall. The children with mild ID also changed their responses to specific questions more often in the repeated interview. The group of children with moderate ID showed markedly lower performance than peers of the same age on nearly every type of eyewitness memory question. Comparisons of the children with ID to mental age-matched peers indicated that performance was similar, although children with ID gave more information in response to free recall instructions and changed their answers in the repeated interview more often. Standardized measures of verbal memory (TOMAL) and suggestibility (Gudjonsson Suggestibility Scale) were modest to moderate predictors of eyewitness memory performance.
