To determine whether pre-adolescent subjects can learn to classify paintings consistently by style or by figure, matched groups of subjects at each of two age levels (7 and 10) were given a pre-test, a seven-week training session, and two post-tests. Subjects at both age levels demonstrated the ability to sort paintings according to a consistent criterion; the older group could more readily alter the basis of its classifications when instructed to do so; style sensitivity was not found to be dependent upon concrete operational thought. Strategies used by subjects and the role of Gestalt perception and operational thought in style sensitivity are discussed.
