Psychological assessment: Projective techniques
As early as 1907, a simple projective test consisting of a series of pictures was available for personality assessment of children. Since the early 1900s, the use of psychodynamically driven personality tests have waxed and waned. For example, in the 1920s and 1930s there were groundbreaking developments such as the Rorschach Ink Blot Test (Rorschach, 1921) and the Thematic Apperception Test (TAT; Morgan & Murray, 1935). These classic early personality tests, which have stood the test of time and are still widely used, have spawned a huge number of derivative tests. A gradual shift took place when the development and popularity of self-report tests led to a reappraisal of, and in some instances skepticism towards, older projective methods. During the 1950s, many psychologists were strident in asserting that projective techniques did not meet established psychometric criteria of reliability and validity.
