The study represents an extension of previous research involving the development of scales for the five-card, orally administered, and tape-recorded version of the Thematic Apperception Test(TAT). Scale development is documented and national norms are presented based on a national probability sample of 1,398 youths administered the Cycle III test battery. As in Cycle II, the youths were administered the Vocabulary and Block Design subtests of the Wechsler Intelligence Scale for Children, the Reading and Arithmetic subtests of the Wide Range Achievement Test, a modified version of the Goodenough-Harris Drawing Test, and the TAT. In addition, a reading and writing literacy test was included in Cycle III. A Continuation of earlier studies through another age range, this study explored the extension of the TAT scales over the teen years and the correlations of the scales developed with available measures of cognitive and emotional behavior.
