This blog has the goal of giving an overall account of the history of projective tests.  Projective tests are a means for assessing personality.  They are rooted in Freud’s notion of unconscious processes.  The purpose of the projective techniques is for people to unconsciously project their personality on to ambiguous or vague stimuli.  They significantly differ from other tests in their range of responses.  Projective tests have a broad number of possible responses, which makes them very difficult to standardize and evaluate. (Trull, 2005)

There are many tests that use projective techniques. Due to the wide variety of this type of test, in addition to focusing on the general history of projective tests, this blog also focuses on the history of the most widely used tests according to Lubin, Larsen, and Matarrazzo (1984), who surveyed psychologists and psychiatrists in many different fields. Specifically, we will look at the Rorschach Inkblot Test, Thematic Apperception Test (TAT), Draw a Person Test, and Sentence Completion Methods. (Lubin, Larsen, & Matarazzo, 1984)
