Comparison of Scores on the Revised Stanford-Binet (L), Columbia Mental Maturity Scale (CMMS) and Goodenough Draw-a-Man Test of Children with Neurological Disorders

Abstract
IQs from three intelligence tests, individually administered to 15 neurologically impaired children, were analyzed for differences between tests requiring speech and non-verbal examinations. All correlations were significantly different from zero, but the Binet gave IQs unlike those from the CMMS and the DAMT. The CMMS and the DAMT yielded similar IQ estimates, suggesting that non-verbal tests of intelligence are more helpful in the examination of children with neurological disorders.
