The clinical psychologist frequently wishes to obtain both performance and verbal I.Q.'s on a child at a single session. To maintain interest and rapport, examiners have sometimes adopted the practice of interpolating the performance sub-tests between the verbal test levels. Since this constitutes a deviation from the conditions under which the Binet test has been standardized, the question has arisen as to whether this practice affects the scores obtained on the two tests. The present experiment was designed to provide an answer to this question.
