Step-by-step explanation:
Mr. Dutoit was taking a psychological assessment called the Thematic Apperception Test (TAT) when asked by his psychotherapist to look at ambiguous pictures and make up a story about each. This type of test is known as a projective test, which is a method of personality assessment that prompts the individual to project their unconscious thoughts and feelings onto ambiguous stimuli. The TAT is particularly known for revealing a person's hopes, fears, interests, and goals through the stories they narrate about ambiguous images.
