The Thematic Apperception Test (TAT) is a projective personality test developed in 1935 using cards with ambiguous images. Participants are asked to tell stories about each image to reveal their attitudes, wishes, and view of the world. Examiners analyze the content, tone, and structure of the stories to understand the test taker's personality. While criticized for being unscientific, the TAT is still used for research and assessing individuals for employment, forensic, and consumer behavior studies. Accurate interpretation requires considering the subject's background characteristics.
