Developed by Swiss psychologist Hermann Rorschach in 1921, the Rorschach Inkblot Test is a projective assessment that uses a series of symmetrical inkblot cards. A psychologist presents each card and asks the client, 'What might this be?' The client's interpretations are analyzed to reveal unconscious feelings and struggles. When standardized with the Exner system, the test is considered an effective tool for measuring conditions such as depression, psychosis, and anxiety.
