Imagery and verbal mediation in paired-associate learning of educable mentally retarded adolescents.

PA learning was investigated among sixty educable mentally retarded adolescents as a function of variations in image-evoking potential of the response members and of instructions to utilise a verbal mediation strategy. The data indicated that performance with verbal mediation instruction surpassed that under non-mediation instruction conditions regardless of imagery level. Results were discussed in terms of Paivio's conceptual peg hypothesis as well as the EMR's deficiency in input organisation.
