The
Rorschach test ( or , ; also known as the
Rorschach inkblot test,
the Rorschach technique, or simply the
inkblot test) is a
psychological test in which subjects' perceptions of
inkblots are recorded and then analyzed using
psychological interpretation, complex
algorithms, or both. Some psychologists use this test to examine a person's personality characteristics and emotional functioning. It has been employed to detect underlying
thought disorder, especially in cases where patients are reluctant to describe their thinking processes openly. The test is named after its creator, Swiss psychologist
Hermann Rorschach.
