Three types of source monitoring by children with and without autism: the role of executive function.

Hala et al. (2005) asked kids to remember where a picture or sound came from.

They tested three kinds of source memory: reality, external, and internal.

Kids with autism and typical kids took the same short tasks while researchers watched for mistakes.

Children with autism made more errors on every source-monitoring task.

The order of task difficulty looked the same in both groups, so the gap was steady, not random.

The authors link the trouble to weaker executive function, not poor memory storage.

Seiverling et al. (2012) later saw the same pattern in adults: fewer specific memories and slower recall, showing the issue lasts past childhood.

Hagopian et al. (2000) seems to disagree—they found intact explicit memory in high-functioning autism. The difference is focus: P et al. tested if kids could store facts, while Suzanne et al. tested if kids knew where the facts came from. Storage is fine; tagging the source is hard.

Reed et al. (2012) and May et al. (2013) add that switching attention between sights and sounds predicts both source errors and lower math scores, tightening the executive-function link.

When a learner with autism insists, “You never told me that,” check source monitoring before assuming defiance. Break down where information came from—show the visual cue, replay the audio, or point to the written card. Strengthening executive skills like attention switching may plug the memory gap and cut down on disputes during instruction.
