| Abstract: | Gave a simplified version of the logical problem-solving task developed by E. D. Neimark to 20 institutionalized and 18 noninstitutionalized retardates and to 20 children from kindergarten through 3rd grade. The performance of the retardates fell below that of the normals of equal mental age. Although the retardates and the younger children solved the problem when the critical information was supplied to them, most of these Ss could not generate the necessary information by themselves, and continued to make redundant responses. For the normals, performance improved up to 81/2-9 yrs of age, at which point 90% reached criterion. Training improved the performance of 7 yr olds but had little or no effect on the performance of 6 yr olds and institutionalized retarded adolescents.
