The test described is the Thematic Apperception Test (TAT), a projective test designed to uncover an individual's unconscious feelings through storytelling.
Step-by-step explanation:
Dr. Doodle showing Sally a picture of a little boy waving to his parents and asking her to tell a story about what is occurring is an example of the Thematic Apperception Test (TAT). The TAT is a projective test where individuals are presented with ambiguous pictures and are asked to tell a story about each picture. This process is used to gain insight into their social world, revealing their hopes, fears, interests, and goals. The purpose of the TAT is to uncover unconscious desires, fears, and struggles. Despite the TAT's modest to low validity and reliability, it remains one of the most widely used projective tests in clinical and counseling settings.
