Abstract
According to Shedd's (1968) formulations, one of the distinguishing characteristics of hyperkinetic children is the score pattern which they earn on different types of ability tests. Specifically, Shedd's work suggests that IQs from a picture vocabulary test, the WISC, and a drawing test should show the following order relationship: picture vocabulary > WISC > drawing. This hypothesis was investigated for 62 overactive children (47 boys and 15 girls) enrolled in classes for learning disabled. The findings support Shedd's since the IQs from the Amnions' test were significantly higher than WISC IQs which were significantly higher than IQs from the Goodenough-Harris. The magnitudes of the mean differences in scores for the three tests were within the range indicated by Shedd and 51 of the 62 children showed the order of scores he specified.
