The growth of intelligence as measured by the Goodenough drawing test

Abstract

Using Thurstone's method of absolute scaling on the original Goodenough data (5627 cases) it was found that, according to these test results: (1) Mental growth increases by decreasing amounts with advancing age. (2) The development of children at different relative intelligence levels progresses along parallel lines. "This… may perhaps be accounted for by the fact that the Goodenough test differs in its nature from other tests cited in that it depends upon a single type of performance and is independent of language ability."
