Maternal speech to verbal and higher functioning versus nonverbal and lower functioning autistic children

Abstract

The relationship between autistic children's level of functioning and maternal speech to children was examined. Ten higher functioning verbal and 10 lower functioning nonverbal children were videotaped in a 15-minute interaction with their mothers. Results revealed that mothers of the higher functioning verbal children asked more questions, used more language modeling, gave more reinforcement for language, and answered more children-initiated questions than did mothers of the lower functioning nonverbal children. Mothers of the nonverbal children employed more directives, used shorter mean lengths of utterance, and reinforced their children's motoric rather than spoken behavior. Far from being poor models for linguistic behavior, mothers of autistic children appear, therefore, to be quite responsive to their children's relative capabilities.
