Systematic reviews and meta-analysis are techniques for synthesizing primary empirical studies to produce a summary of effects. To facilitate this goal, the Campbell Collaboration (C2) supports reviews within the disciplines of crime and justice, education, international development, and social welfare. At the annual Campbell Colloquium, experts…

Prior research has established that peer tutors can benefit academically from their tutoring experiences. However, although tutor learning has been observed across diverse settings, the magnitude of these gains is often underwhelming. In this review, the authors consider how analyses of tutors' actual behaviors may help to account for variation in…

Using an ABAB design, two procedures for requesting a change of activity were compared for their effect on the stereotypic behavior of a man with autism. One procedure requested immediate change of activities, whereas the second procedure gave advance notice of a change. Less stereotypy occurred when advance notice of change was given. (Author/DB)

The effects of social interaction skill interventions on the social behavior of four preschool children with behavioral handicaps were evaluated. Findings indicated unique effects for social skills training and contingency management intervention. Results are discussed in relation to the role of reciprocal interaction and behavioral trapping for…

Two children (ages four and five) with word-finding deficits characterized largely by semantic substitutions participated in a treatment involving phonological information about target words. Treatment resulted in reduction not only of occasional phonological word-finding substitutions but also of the large number of semantic word-finding…

This study examined a system for fading teacher prompts to children who served as peers in peer-initiation interventions for young children with disabilities (n=6). Results indicated that social interaction continued at the levels found during intervention and was maintained during a short maintenance period. (Author/DB)

The combined effects of double-prompting and booster session procedures on the social behavior of four socially withdrawn preschool children were investigated. Results indicated that the intervention procedures increased subjects' initiations in organizing play, sharing, and assisting and that there were collateral increases in subjects'…

High-probability requests were used to increase responsiveness to low-probability requests to initiate social interactions in three young boys with severe disabilities who were severely socially withdrawn. Increases were also found in unprompted social initiations and generalizations to a nontraining setting. Maintenance after training was also…

This study compared the relative effectiveness of imitative intervention and conversational recast language intervention applied to grammatical morpheme and complex sentences in 21 children with specific language impairment. The conversational procedure was found to require fewer presentations to first spontaneous use and to produce more…

This article describes an intervention in which three parents were taught to use facilitative strategies when interacting with their children with profound mental retardation. The intervention consisted of reinforcing appropriate parent behavior as it was being observed by them on prerecorded videotapes. Facilitative strategies included the use of…

A multicomponent intervention to change problem behavior, which prevented community integration of three adolescents with autism, was evaluated. The intervention (implemented in a supermarket setting) included choice making, embedding, functional communication training, building tolerance for delay of reinforcement, and presenting discriminative…

A behavioral consultation approach was effectively used to reduce problem behaviors in 2 field studies with 3 students (ages 10-14) having severe or profound mental retardation and their teachers. Intervention involved extinction of inappropriate behaviors, reinforcement of appropriate play behaviors, and teaching verbal skills functionally…

The effects of two methods of negative reinforcement on three young children (ages two and three) with developmental delays and chronic food refusal were examined. Physically guiding the child to accept food contingent on noncompliance and nonremoval of the spoon until the child ate were tested. Both treatments were effective; however, parents…

The primary and generalized effects of Enhanced Milieu Training were examined with six preschool children with significant language delays. Children systematically increased their use of target language skills during the intervention sessions, and these changes were maintained when treatment was discontinued. Some generalization to untrained…

Using seven trainable mentally-retarded students, aged 10-19, the study assessed the efficacy of an action mnemonic procedure for teaching letter-sound correspondences. The subjects were successfully trained to emit appropriate action-sounds in the presence of pictures incorporating the target letter, with picture-prompts being gradually faded to…
