Recall of a live and personally experienced eyewitness event by adults with autism spectrum disorder.
Adults with autism remember real events well but mix up sources unless you give clear, structured prompts.
01Research in Context
What this study did
Matson et al. (2013) asked adults with autism to remember a real event they had just seen. The event was a brief staged theft in the lab. Right after, each adult told the story twice: once with no help and once with gentle prompts.
The team counted correct details, wrong details, and source errors. A source error is saying "I saw" when you only heard it.
What they found
Adults with autism recalled just as many correct facts as typical adults. They made more mistakes about where each fact came from. Free-form storytelling produced the most errors. Prompted recall cut the error rate.
How this fits with other research
Hilton et al. (2010) showed that the fancy cognitive interview hurts accuracy in the same group. The new study says even plain free recall is risky. Together they point to the same fix: use structured prompts early.
Jackman et al. (2018) later found that letting autistic children sketch while they talk also lowers errors. The tactic differs, but the goal matches—give the witness a scaffold.
Hsu et al. (2017) swapped the human for a computer avatar and saw a small boost with kids. Again, structure helps, whether it comes from drawings, avatars, or simple wh- prompts.
Why it matters
If you interview an adult client about a challenging incident, start with who, what, where prompts instead of "Tell me everything." This small shift keeps their accurate memory while trimming the guesswork. Use the same rule when training staff or writing behavior plans that rely on self-report.

03Original abstract
The aim of the present study was to (a) extend previous eyewitness research in autism spectrum disorder (ASD) using a live and personally experienced event; (b) examine whether witnesses with ASD demonstrate a facilitative effect in memory for self- over other-performed actions; (c) explore source monitoring abilities by witnesses with ASD in discriminating who performed which actions within the event. Eighteen high-functioning adults with ASD and 18 age- and IQ-matched typical counterparts participated in a live first aid scenario in which they and the experimenter each performed a number of actions. Participants were subsequently interviewed for their memory of the event using a standard interview procedure with free recall followed by questioning. The ASD group recalled just as many correct details as the comparison group from the event overall, however they made more errors. This was the case across both free recall and questioning phases. Both groups showed a self-enactment effect across both interview phases, recalling more actions that they had performed themselves than actions that the experimenter had performed. However, the ASD group were more likely than their typical comparisons to confuse the source of self-performed actions in free recall, but not in questioning, which may indicate executive functioning difficulties with unsupported test procedures. Findings are discussed in terms of their theoretical and practical implications.
