Conversational analyses of males with fragile X, Down syndrome, and autism: comparison of the emergence of deviant language.
Deviant, repetitive language of 33 males (9 with Down syndrome, 12 with fragile X (fra[X]) syndrome, and 12 with autism) was analyzed within three conversational contexts: direct responses, initiation of new material, and topic maintenance. Results indicated that males with fra(X) manifest deviant, repetitive language that is distinct from males with either Down syndrome or autism. Thus, the deviant repetitive language of males with fra(X) cannot be accounted for by either their level of adaptive functioning or autistic-like behaviors per se. Possible explanations for this etiologically specific language deviance were discussed.
