Autism & Developmental

Deficits in free recall persist in Asperger's syndrome despite training in the use of list-appropriate learning strategies.

Smith et al. (2007) · Journal of autism and developmental disorders 2007
★ The Verdict

Strategy training alone does not fix word-memory gaps in adults with Asperger’s, so give external cues.

01Research in Context

01

What this study did

The team worked with the adults who had Asperger’s Syndrome. They also tested the adults without autism who were the same age and IQ.

Everyone first tried to remember three word lists without help. Next, the researchers taught two memory tricks: group words by meaning or by sound. Then they tried the lists again.

02

What they found

Even after the lesson, the Asperger group recalled fewer words on every list. The tricks did not close the gap.

Their memory stayed weak no matter which trick they used. The authors say the problem is deeper than strategy use.

03

How this fits with other research

Eugenia Gras et al. (2003) saw the same recall gap four years earlier in the same lab. That paper also showed that people with Asperger’s add extra words that were never on the list. The new study extends that work by proving that teaching tricks does not fix the issue.

Daoust et al. (2008) found a similar drop in spoken recall, but with dream stories instead of word lists. Both studies point to a broad, content-wide recall weakness in verbally able adults with ASD.

At first glance, Boucher (2007) seems to disagree. One adult with Asperger’s wrote that he could remember well by using self-taught rules. The difference is method: the group experiment shows average failure, while the single case shows rare success. Both can be true.

Why it matters

If you teach a client a memory strategy and it flops, the paper says it is not your teaching. The client may still need picture cues, written lists, or apps that store the info for them. Build these supports into job coaching, college prep, and daily living goals instead of drilling more strategies.

03Original abstract

Free recall in adults with Asperger's Syndrome (AS) was compared with that in matched controls in an experiment including semantically similar, phonologically similar and unrelated word lists. Without supportive instructions, adults with AS were significantly impaired in their recall of phonologically and semantically related lists, but not unrelated lists. Even when trained to make use at study of the relations among the words, the adults with AS recalled fewer words than the control group. Participants rehearsed the study lists out loud and the rehearsal data was analysed. Despite a very slight trend for adults with AS to engage in less elaborative rehearsal and more rote rehearsal, their rehearsal did not differ significantly from that of controls.
