Autism & Developmental

Subjective organisation in the free recall learning of adults with Asperger's syndrome.

Bowler et al. (2008) · Journal of autism and developmental disorders 2008
★ The Verdict

Adults with Asperger’s recall facts fine, but their mental filing system stays quirky and won’t improve with practice.

✓ Read this if BCBAs working with verbal adults on the spectrum who need to remember sequences or instructions.
✗ Skip if Clinicians serving only young children or clients with minimal verbal skills.

01Research in Context

01

What this study did

The team asked adults with Asperger’s to learn lists of words.

Everyone tried to recall the words several times.

The researchers watched how people grouped the words in their minds.

02

What they found

Adults with Asperger’s remembered about the same number of words on any one try.

Their way of sorting the words stayed odd and personal.

Typical adults slowly lined the words up the same way; the Asperger group never did.

03

How this fits with other research

Stancliffe et al. (2007) tried teaching memory tricks first. Even after coaching, adults with Asperger’s still recalled fewer words. The new study shows the tricks fail because their groups never converge.

Pettingell et al. (2022) flipped the task: let autistic adults act out the list with toys instead of speaking. Visuospatial recall beat spoken recall. Together the papers hint the block is verbal organization, not memory itself.

Eugenia Gras et al. (2003) saw more false intrusions in the same population. Idiosyncratic grouping may open the door for wrong items to slip in.

04

Why it matters

When you ask clients to recall steps, stories, or rules, don’t wait for them to “get better” at lining things up. Give picture lists, written checklists, or let them show you the answer. Shift the mode, not the mind.

03Original abstract

Single trial methods reveal unimpaired free recall of unrelated words in Asperger's syndrome (AS). When repeated trials are used (free recall learning), typical individuals show improved recall over trials, subjective organisation of material (SO) and a correlation between free recall and SO. We tested oral (Experiment 1) and written (Experiment 2) free recall over 16 trials in adults with AS and typical individuals. Across both experiments AS participants showed marginally diminished recall. Poorer SO was seen in the Asperger group only in Experiment 2, but in both experiments, individual differences in SO in the Asperger group were less likely to converge over trials. This lack of convergence suggests that the AS group organise material in idiosyncratic ways.
