Double alternation: a measure of intelligence

Using the Double Alternation Card Test, first introduced by J. McV. Hunt, 240 public school males ranging from 6 to 12 years in chronological age were tested. Tentative norms are offered, and "because of the nonverbal aspects of the Card Test plus the high correlations between measures on this test and measures mental age, it is felt that this technique can be a valuable addition to the clinician's test battery, particularly in instances where the testee suffers language handicaps, aphasia, or speech disorders."
