Rorschach test research

In the 1937, Piotrowski published research on ten indicators, found using Rorschach tests, that indicate the presence of organic brain disease. These have since been called Piotrowski signs. He developed a method of analysis for the Rorschach test he termed perceptanalysis, which emphasized perception of the images rather than secondary associations.
