Thematic Apperception Test (TAT) is a psychological assessment tool used to evaluate a person's underlying motives, concerns, and the way they perceive social situations. During the test, individuals are shown a series of ambiguous images and asked to create stories about them. The narratives they produce can reveal their thoughts, feelings, and personality traits. Developed by Henry A. Murray in the 1930s, the TAT is often used in clinical settings and research to gain insights into a person's emotional functioning. The test is based on the idea that people project their own experiences and emotions onto the images, providing valuable information for psychologists.
