Multiple list learning in adults with autism spectrum disorder: parallels with frontal lobe damage or further evidence of diminished relational processing?
High-functioning adults with autism recall fewer words and use category links less, so give extra relational cues and check transfer.
01Research in Context
What this study did
The team asked adults with autism to learn two short word lists.
They compared recall and grouping to adults without autism.
All adults were high-functioning and matched for age and IQ.
What they found
The autism group remembered fewer words overall.
They also grouped words into categories less often, especially on the second list.
Even when they tried to organize, the benefit was smaller.
How this fits with other research
Emerson et al. (2023) repeated the test and got the same pattern, so the result is solid.
Barton et al. (2019) saw the same trouble with abstract links in children, showing the issue starts early.
Redquest et al. (2021) found kids with autism focus on tiny details and mix up similar pictures.
Together, the studies say the problem is not poor memory space, but weaker use of big-picture links.
Why it matters
When you teach a client new skills, do not assume they will link ideas on their own.
Give clear category labels, visible groups, or spatial cues.
Check that they can still use those links on the next list or next day.
A quick prompt like “these three go together because they are animals” can save re-teaching time.

03Original abstract
To test the effects of providing relational cues at encoding and/or retrieval on multi-trial, multi-list free recall in adults with high-functioning autism spectrum disorder (ASD), 16 adults with ASD and 16 matched typical adults learned a first followed by a second categorised list of 24 words. Category labels were provided at encoding, retrieval, both or not at all. Both groups showed enhanced recall when labels were available during encoding or throughout the task. ASD individuals showed reduced recall of the second list and reduced clustering. Clustering and recall were correlated in both groups, which also showed similar levels of subjective organisation. The findings are discussed in relation to theories of frontal and medial temporal lobe contributions to memory in ASD.
