Asperger's syndrome and memory: similarity to autism but not amnesia.

Two experiments are described in which the memory of adults with Asperger's syndrome is compared with that of verbal IQ controls. The results of the first experiment showed that the Asperger subjects resembled autistic adults and children in their failure to use category information to aid their free recall. In the second experiment, both groups of subjects showed similar priming effects in an implicit stem completion task and similar performance on an explicit cued recall task. Moreover, both groups also showed more priming for items that they had read at study and better recall for items that they had to generate at study, suggesting that the cued recall of the Asperger subjects did not result from contamination by automatic or involuntary processes.
