Supporting older adults’ episodic remembering

Environmental support at retrieval improves episodic performance, yet there exists very few empirically evaluated techniques for supporting older witnesses/victims’ remembering (> 65years). We investigated two techniques for use in a criminal justice context - the Self-Administered Interview and Sketch Reinstatement of Context. Older adults (N =134) witnessed an unexpected live event, following which half immediately completed a Self-Administered Interview and half did not (Time 1). All were interviewed 48 hours later (Time 2) using one of three face-to-face interview techniques: Sketch Reinstatement of Context, Mental Reinstatement of Context, or no support Control. Those who completed a Self-Administered Interview at Time 1 recalled more correct information at Time 2 irrespective of interview condition and confabulated less. Likewise, participants interviewed using the Sketch Reinstatement of Context technique recalled more correct information and confabulated less, whether they had completed a Self-Administered Interview, or not. However, the Self-Administered Interview + Sketch Reinstatement of Context was the most effective combination, indicating an interaction between stabilizing a memory trace quickly and how sketching appears to scaffold memory retrieval during face-to-face interviews.
