Development of Language Behavior in an Autistic Child

Abstract
A systematic attempt to develop language in a nonverbal autistic boy is described. The approach taken involved teaching him to attend, increasing his responsiveness to people, effecting discriminative responses to a variety of controlled auditory and visual stimuli, increasing the extent of and rate of his vocal and nonvocal behavior, and increasing his behavior by verbal commands. Results are presented which show the relative effectiveness of the treatment methods used. The subject showed an increase in the frequency and variety of verbal and nonverbal behavior.
