Sketching to remember: episodic free recall task support for child witnesses and victims with autism spectrum disorder.

Deficits in episodic free-recall memory performance have been reported in children with autism spectrum disorder (ASD), yet best practice dictates that child witness/victim interviews commence with a free-recall account. No 'tools' exist to support children with ASD to freely recall episodic information. Here, the efficacy of a novel retrieval technique, Sketch reinstatement of context (Sketch-RC), is compared with mental reinstatement of context and a no support control. Ninety children (45 with ASD; 45 matched typically developing) viewed a stimulus film, and were interviewed using one of the aforementioned techniques. The Sketch-RC technique was most effective, improving ASD participants' remembering without a concomitant increase in intrusions. This procedure offers a population-appropriate method for supporting free recall in criminal justice settings.
