Projective tests are personality tests that reveal hidden emotions and internal conflicts by having people respond to ambiguous stimuli. They are based on the psychoanalytic idea that people have both conscious and unconscious attitudes. Common projective tests include the Rorschach inkblot test, Thematic Apperception Test, word association tests, sentence completion tests, and cartoon tests. Responses are analyzed to infer unconscious personality traits, motivations, and perceptions.
