The report summarizes research on the development of an objective scoring system and the formulation of scales useful in the assessment of psychological development and normal behavior using a five-card, orally administered and tape-recorded version of the Thematic Apperception Test (TAT). The TAT language scales which were developed represent innovative measures of oral speech based on controlled samples of spontaneously produced speech and represent an important original contribution. The TAT language scales provide a basis for scoring verbal factors from actual samples of speech. National norms for children ages 6-11 are presented for these scales. Two studies are reported. In the first study, a major emphasis was placed on the development of usable scales, while in the second study, the major focus of the present report, involves cross validation and refinement of the scales, as well as provision of national norms for the scales.
