Results of a study involving 14 three- to 11-year-olds with language impairments revealed that, for both functor acquisition and functor recall, speech and sign training was superior to speech training. Type of functor trained was also important, with prepositions faring better than pronouns. (Author/CL)

Four nonverbal autistic boys (ages 11-16) were successfully taught sign language action-object phrases following an intervention composed of prompting, fading, stimulus rotation, and differential reinforcement. The skill generalized to new situations. (Author/DB)

The longitudinal study investigated the language acquisition strategies employed over one and one-half years by an eight-year-old autistic child learning sign language. There were specific deviations in language development noted, in spite of providing the child with appropriate sign language training. (Author)

Sixty minimally verbal autistic children (mean age five years) were exposed to one of four language training conditions: speech alone, sign alone, or simultaneous or alternate presentation of speech and sign. Regardless of training condition, pretreatment verbal imitation ability positively predicted the size of child-initiated spoken vocabulary…

Sign language production of 14 low-functioning students (ages 9 to 20) with autistic disorder were examined. The location aspect of signs was produced more accurately by subjects than either the handshape or movement aspects. Wide individual differences were observed. Sign vocabulary size and accuracy was correlated with performance on two…

Empirical studies evaluating speech and language intervention procedures applied to children with autism are reviewed and the documented benefits are summarized. In particular, interventions incorporating sign language, discrete-trial training, and milieu teaching procedures have been used successfully to expand the communication repertoires of…
