Abstract

The Yule-Oseretsky test of motor performance was administered to 10 `undifferentiated' mentally-retarded adults, 10 normal children and 10 normal adults. In accordance with Denny's (1964) 3-group design, the children were matched on mental age with the retardates, the normal adults were matched on chronological age with the retardates, and the children and normal adults were matched on intelligence quotient. The results showed that mental age predicted performance on both fine and gross motor tasks, with the children and retarded adults both obtaining similar relatively-low scores.
