Rorschach test research

These have since been called Piotrowski signs.JOURNAL, Aita, John A., Reitan, Ralph M., Ruth, Jane M., Rorschach's Test as a Diagnostic Aid in Brain Injury, American Journal of Psychiatry, May 1947, 103, 6, 770–779, 10.1176/ajp.103.6.770, 20243412, He developed a method of analysis for the Rorschach test he termed perceptanalysis, which emphasized perception of the images rather than secondary associations.{{fv|date=October 2022|reason=Only mentions the existence of his 1957 Perceptanalysis book, not anything about the method.}}
