Abstract
Apart from their diagnostic value, psychological tests, especially the Rorschach test, have an important theoretical value for understanding psychopathology. They present a picture of a living person, in contrast to a picture of forces and agencies within the person. This rests on 2 advantages of tests over the usual psychiatric and psychoanalytic interviews: Tests are ahistorical and they present information primarily of a formal kind.
