A measure of needs to assess the stimulus characteristics of TAT cards

Summary: The stimulus demands of TAT cards were evaluated by means of a TAT-Adjective Rating Scale. Seventeen needs were measured through adjective ratings. Mean needs were reported for 191 males and 85 females. Variability was used to develop a measure of stimulus ambiguity. Also investigated was (a) the partitioning of variance for subjects, cards, needs and their interactions, and (b) sex differences were evaluated by means of analysis of variance.
