Personality tests that ask individuals to respond to vague, ambiguous stimuli in ways that may reveal the subject's needs, feelings, and personality traits are referred to as projective tests.
The term comes from the word projection, which denotes the act of attributing one's own thoughts, feelings, or motives to another. The most famous projective method of psychological testing is the Rorschach test, or also called Rorschach inkblot test. During this test a person is asked to describe what he or she sees in 10 inkblots.
