A simultaneous treatments design was used to compare effects of modeling and corrected practice on generative language acquisition of six preschoolers. New syntactic forms used to describe agent-action-object stimuli were taught concurrently. All six children learned both new syntactic forms. Corrected practice produced a faster rate of learning.…

The effects of expressive modeling experiences on the observational learning of generative language by children with severe mental retardation was investigated. All six children (aged six-nine) demonstrated observational learning of responses modeled by their peers. Organizing the modeling experiences according to matrix-training principles…

Two experiments investigated the effects of peer modeling on the acquisition of receptive and expressive language responses. Experiment 1 studied lexical learning among five children who were mildly/moderately developmentally disabled. Experiment 2 investigated the observational learning of receptive and expressive language responses by two…

A study investigated the effects of using videotaped self-modeling on the acquisition of new linguistic structures used for requesting in three preschoolers with developmental disabilities. Participants were able to learn through self-modeling; however, initial difficulties with generalization to the classroom setting were found. (CR)
