Does extensive free narrative prompting minimise the effect of mental reinstatement on children's recall of events?

The effect of mental reinstatement on children's recall is unclear. One factor that may impact its effectiveness is the degree to which interviewers prompt children during an interview. We examined whether interviewers’ degree of narrative prompting moderated the effect of mental context reinstatement during children's recall of a staged event. Younger and older children were interviewed 7–10 days after the event. Half were told to mentally reinstate the context and half were not. In a fully crossed design, half also received extended narrative prompting during the interview and half did not. We predicted that extensive narrative prompting should reduce any observable benefit of mental reinstatement, especially for older children. However, mental reinstatement had no beneficial effect on recall performance. It is possible that methodological differences, low statistical power, and a small effect size may have reduced the observable benefit of mental reinstatement in comparison to other studies. Overall, the findings of this study suggest that until further research can clearly define the parameters in which mental reinstatement is useful, and therefore produce findings with greater consistency across studies, there is little support for its use in investigative interviews with child witnesses.
