Tests of General Intelligence
The Goodenough—Harris Drawing Test has its origins in the Goodenough Draw-a-Man Test, which was developed in 1926 and revised by Harris in 1963. It requires the subject to draw a man; alternate forms include instructions for the subject to draw a woman or to draw himself or herself. It is scored on the basis of 73 items related to the detail, the proportion, and the position of the drawing. The result of this scoring procedure is known as the Point Scale. There is also a set of quality scores, which are determined by comparison with a set of 12 drawings said to represent different levels of conceptual maturation. The Quality Scale can be transformed into IQ estimates. The Goodenough—Harris can be administered to either a group or an individual. Age-related norms are available for individuals between the ages of 5 and 15. The score values are normally distributed and increase with age (Scott, 1981).
