Thematic Apperception Test


Every year in the field of psychology there are an increasing number of publications on the Thematic Apperception Test (TAT). The ongoing research covers the entire gamut of possible applications of the TAT and other instruments which use a TAT format. Although the TAT is one of the most popular psychodiagnostic instruments, one of the pressing problems is the low reliability and validity estimates which have been found. This study was designed to test the validity of a simple, objective method of scoring the TAT. Fifty male and fifty female introductory psychology students were divided into two groups, 25 of each sex in a group, for a total of 50 subjects per group. The Experimental group was given a letter which was designed to induce anxiety and then given the standard instructions for the TAT. The Control group received only the standard instructions. The responses were analyzed by taking a word count of each story of each subject to the TAT cards. An analysis of variance was run to determine the sources of variance. Only the interaction of the TAT cards by treatment groups was significant. The result was discussed in terms of its applicability to the general use of the TAT.
