Dyads of siblings in which the younger sibling had an intellectual disability (ID, n = 25) were videotaped interacting. The ID group was compared with typically developing sibling dyads matched on mental age (n = 25) and chronological age (n = 25). We observed the mediation strategies, activation, and antimediation behaviors of older siblings and…

Background: Intellectual and developmental disability (IDD) researchers have been relatively slow to adopt the search for moderators and mediators, although these variables are key in understanding how and why relationships exist between variables. Although the traditional method of causal steps is useful for describing and understanding…

The research examined the effect of an intervention program employing 3D immersive virtual reality (IVR), which focused on the perception of sequential time, on the mediation level and behavioural aspects of children with intellectual disability (ID). The intervention is based on the mediated learning experience (MLE) theory, which refers the…

Investigated with 40 trainable mentally retarded children was the use of instructional modeling to teach visual and verbal mediation skills. (Author)

The focus of the study was on the paired-associate performance of retarded subjects of different levels of mental age under various instructional conditions. (WY)

Compared six experimental conditions to determine whether specific formats of interrogatives would be instrumental in inducing the generation of effective verbal mediators for 30 nonretarded and 60 educable mentally retarded children. (Author/JMB)

This introductory paper covers basic concepts and terminology relevant to the application of research on relational learning to mental retardation. The paper discusses conditional discrimination; conditional stimulus relations and stimulus equivalence; generalized stimulus relations; impact of mediational processes on emergent behavior; relational…

The effectiveness of verbal and imaginal elaborations on the free recall of 50 educable mentally retarded adolescents was investigated. Ss were assigned to one of five conditions: experimenter-imposed verbalization (EV), experimenter imposed imagery (EI), subject-generated verbalization (SV), subject-generated imagery (SI), and control (C). Ss saw…

The primary purpose of this study was to determine if the mentally retarded child is capable of the long-term retention of mediational links that he has formulated previously on a paired-associate task. (Author)
