The Thematic Apperception Test (TAT) is a performance-based measure of personality that involves storytelling using real images, allowing for a more structured assessment of personality traits compared to the Rorschach inkblot method. Developed by Henry Murray at Harvard in the 1930s, the TAT generates rich thematic data, structural insights, and behavioral observations that reveal individuals' underlying needs, attitudes, and interpersonal relationships. The test consists of 31 cards featuring various scenes, prompting examinees to create narratives that highlight their perceptions and emotional responses.
