Abstract
Providing cues to facilitate the recovery of source information can reduce postevent misinformation effects in adults, implying that errors in source-monitoring contribute to suggestibility (e.g., [Lindsay, D. S., & Johnson, M. K. (1989). The eyewitness suggestibility effect and memory for source. Memory & Cognition, 17, 349–358]). The present study investigated whether source-monitoring plays a similar role in children’s suggestibility. It also examined whether the accuracy of source judgements is dependent on the type of source task employed at test. After watching a film and listening to a misleading narrative, 3–4- and 6–7-year-olds ( n = 116) were encouraged to attend to source memory at retrieval. This was achieved either via sequential “question pairs”, which are typically used in children’s source-monitoring research, or via a novel “posting-box” procedure, in which all source options were provided simultaneously. Performance elicited by each type of source task was compared with that evoked by old/new recognition procedures. Posting-box, but not question pair, source cues were effective at reducing the magnitude of the suggestibility effect, relative to that observed under recognition conditions. Furthermore, source question pairs provoked a bias to respond affirmatively for 3–4-year-olds. The findings imply that children’s suggestibility may be partially explained by sub-optimal use of intact source information, which may be activated by age-appropriate strategies at retrieval.
