title: Verbal fluency in adults with high functioning autism or Asperger syndrome.
abstract: The semantic and phonemic fluency performance of adults with high functioning autism (HFA), Asperger syndrome and a neurotypical control group were compared. All participants were matched for age and verbal ability. Results showed that the participants with HFA were significantly impaired in their performance of both semantic fluency tasks and the phonemic fluency task using the letter M. The Asperger group was only impaired in their performance of the semantic fluency task 'professions'. The social components of the 'professions' task may have influenced the performance of the two disorder groups for this subtest negatively. The fluency deficits could not be attributed to a lack of the use of strategies or to difficulties in switching between strategies. The impairment in two of the three verbal fluency subtests in the HFA group can be attributed to the relatively low processing speed found in this group.
