Rorschach test research[edit]

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.^[5] He developed a method of analysis for the Rorschach test he termed perceptanalysis, which emphasized perception of the images rather than secondary associations.^{[2][failed verification]}
