Flexibility training with educable retarded children

This experiment was designed to test the hypothesis that training in perceptual and cognitive shifts would improve the performance of EMR children on flexibility measures and on the Binet and WISC scales. Twenty-eight children received 42 exercises in cognitive flexibility and were compared to a control group that was matched on mental age. Instruction facilitated performance on variables measuring verbal fluency and concept formation; however, significant improvement was generally limited to those variables which shared content with the training exercises.
