  • Title: Solving complex perceptual discrimination problems: techniques for the development of problem-solving strategies.
    Author: Guralnick MJ.
    Journal: Am J Ment Defic; 1976 Jul; 81(1):18-25. PubMed ID: 782244.
    Abstract:
    Techniques for developing problem-solving strategies in handicapped children when they are faced with complex perceptual discriminations were investigated. Specifically, the effectiveness of feedback, modeling, and self-instruction were compared with each other and a control condition on a specially designed matching-to-sample task. The task was designed so that the distinctive features of the stimuli could be identified for instructional purposes. The results indicated that only the self-instruction technique facilitated performance on the posttest. In addition, these skills generalized to a new set of forms but not to the Matching Familiar Figures test. These findings were further related to the development of observational skills.
