title: Perceptual-motor testing of mentally retarded persons.
abstract: The application of a restructured subtest of an intelligence scale to retarded persons, including those with Down's syndrome, led to no significant differences according to diagnostic group. With several subjects (10 percent of the total), more difficult tasks could be accomplished with success in contrast to simpler ones, and such findings were discussed in terms of increased structure and learning sets.
