title: Two-year follow-up study of discrimination learning by mentally retarded children.
abstract: Mentally retarded children were taught to discriminate the dimensions of a visual display using a matching-to-sample procedure that provided full verbal feedback of the reasons for successes and failures. A control group attempted the matching procedure but received no feedback. The trained subjects exhibited marked superiority in intradimensional transfer. Two years later, the trained subjects continued their advantage but to a lesser degree.
