Implicit and explicit memory in autism: is autism an amnesic disorder?
High-functioning autism is not amnesia; memory is whole but needs better filing.
01Research in Context
What this study did
Hagopian et al. (2000) tested kids with high-functioning autism on two kinds of memory.
They used simple lab tasks to see if the children had amnesia-like gaps.
The design matched each autistic child to a typical peer for comparison.
What they found
Memory systems were intact.
Kids could recall facts and learn patterns as well as controls.
The only odd note was how they ordered lists: they skipped the usual middle dip.
How this fits with other research
Seiverling et al. (2012) looked at real-life stories in adults with ASD.
They found fewer specific memories and slower answers, yet the same rules of recall applied.
The two studies seem opposite—intact vs. poor memory—but they test different things.
Lab memory stays whole; personal memory needs extra support.
Coutelle et al. (2020) added that fuzzy self-concept may drive the personal gap.
Foldager et al. (2023) showed the same pattern in word lists: autistic kids give fewer items, hinting at organization issues, not lost storage.
Why it matters
You can stop worrying that your learner “can’t remember.”
Instead, teach how to organize and tag memories.
Use visual scripts, category bins, or story maps during social skills groups.
These scaffolds turn intact storage into usable recall.

03Original abstract
Medial temporal lobe amnesic disorder is characterized by an impairment in explicit memory (e.g., remembering a shopping list) and intact implicit memory (e.g., a woman seems familiar although you cannot remember having met her before). This study examined whether children with high-functioning autism have this same dissociation between explicit and implicit memory abilities. Children with autism and normal development participated in three memory tasks: one implicit task (perceptual identification) and two explicit tasks (recognition and recall). Children with autism showed intact implicit and explicit memory abilities. However, they did not show the typical pattern of recalling more items from both the beginning and end of a list and instead only recalled items from the end of the list. These results do not support the theory that high-functioning autism is a type of medial temporal lobe amnesia. However, these findings suggest that persons with autism use different organizational strategies during encoding or retrieval of items from memory.
