The Thematic Apperception Test (TAT), developed in the 1930s by psychologist Henry Murray and psychoanalyst Christiana Morgan, is a projective test where an individual is presented with 8 to 12 ambiguous pictures and asked to create a story for each. The narratives are believed to offer insight into the person's social world, including their hopes, fears, interests, and goals. The storytelling approach is designed to reduce resistance to revealing unconscious personal details. Despite being one of the most widely used projective tests, particularly for evaluating psychological difficulties in clinical settings, its validity and reliability are often considered modest to low.
