The Subconscious Test (TAT) is primarily used to assess and analyze an individual's inner world, subconscious motivations, emotional state, personality traits, and potential psychological conflicts. By asking the test taker to create stories based on a series of ambiguous or vague images, TAT reveals the test taker's inner psychological dynamics, desires, fears, and conflicts. This test is commonly used in clinical psychology, counseling, and personality research to gain deep insights into an individual's psychological structure and motivations.
