Prediction of locus of control orientation from the Thematic Apperception Test

This study attempted to predict locus of control orientation from responses to the Thematic Apperception Test. Forty male and 40 female undergraduates who scored at the extremes on the Rotter Locus of Control Scale responded to TAT cards. By use of Dies' rating procedure; two judges predicted Ss' locus of control orientation with 70% accuracy. Because an external orientation was predicted with much greater efficiency than an internal orientation, it was suggested that the TAT cards may elicit more external than internal responses.
