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.…

Matrix training strategies were used to teach three severely mentally retarded children syntactic rules for combining known words into two- and three-word utterances. Training only a limited number of responses was sufficient to promote recombinative generalization in the trained modality and transfer to untrained responses in the opposite…

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…

Four nine year olds with mild mental retardation received training on the meaning of idiomatic phrases. All children demonstrated learning and an ability to understand the learned idioms when presented in unfamiliar contexts. Children were able to generalize their receptive learning to an expressive task with varying levels of success. (Author/JDD)

Four developmentally delayed preschoolers were taught action-object responses in receptive and expressive language modalities, using matrix-training procedures. Acquisition of a word combination rule was facilitated by the use of familiar lexical items, whereas subsequent acquisition of new lexical knowledge was enhanced by couching training in a…

Two children, aged six and nine, with moderate mental retardation were taught syntactic rules for combining known and unknown words into two-word utterances. The use of receptive teaching with imitation of the target phrase facilitated both generalized receptive learning and transfer to production in both subjects. (Author/JDD)

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)

A study evaluated the use of computer-assisted instruction (CAI) to provide training in phonological sensitivity skills to 45 preschool children at-risk for reading problems. Children exposed to CAI made significantly greater gains on rhyming and elision skills compared to controls. Expressive vocabulary scores were predictive of pre- to posttest…
