We review recommendations for sequencing instruction in receptive and expressive language objectives in early and intensive behavioral intervention (EIBI) programs. Several books recommend completing receptive protocols before introducing corresponding expressive protocols. However, this recommendation has little empirical support, and some…

Researchers and clinicians have recommended that sign language be taught to typically developing children during their first 2 years of life; however, existing research does not provide adequate information regarding appropriate methods of sign training. We used delayed physical prompting and reinforcement to teach manual signs to 3 children…

Six autistic children were trained to use their sign repertoire to make spontaneous requests of adults. Training consisted of imitative prompting, fading, and differential reinforcement, with aspects of incidental teaching. Ss displayed increased rate and variety of spontaneous sign requests and generalization of spontaneity across different…

Two methods (signs presented with or without accompanying verbal label) of training autistic children to use manual signs were compared. The efficacy of training in both treatment conditions was demonstrated but no clear differences in acquisition speed across conditions were apparent. (Author/CL)

Five children with severe educational retardation, aged 5-12, were involved in sign training in which the spoken words corresponding to signs were receptively known to participants. Whether signs were taught concurrently or in a serial fashion, signs taught by total communication were acquired faster than those taught by sign-alone training.…

A six-year-old nonvocal girl with autism who had acquired a variety of signs and imitative responses consistently failed to acquire a tact (labeling) repertoire. When procedures to transfer stimulus control from verbal to nonverbal stimuli were implemented, the subject quickly learned to tact all 18 target stimuli. (Author/DB)
