Projective tests are personality assessment tools that are used to study personality and provide therapy. A projective personality test provides ambiguous stimuli designed to trigger projection of one’s inner dynamics. They aim to provide a “psychological X-ray” by asking test-takers to describe an ambiguous stimulus or tell a story about it. One such test is the Thematic Apperception Test (TAT) in which people view ambiguous pictures and then make up stories about them. This story telling has been used to assess achievement motivation. The most widely used projective test is the Rorschach inkblot test, in which people describe what they see in a series of inkblots. There are arguments in favor of and in opposition to these tests, arguing that the results are not consistent in validity.
