Piotrowski's enduring contributions to the Rorschach: a review of Perceptanalysis

Zygmunt A. Piotrowski (1904-1985), one of the early pioneers with the Rorschach technique, developed a method for Rorschach analysis described in the text, Perceptanalysis. Based on clinical, teaching, research, and supervisory experiences, the author selected three aspects of the text for review for their enduring contributions to clinical personality analysis. The three areas are: (a) the scientific and philosophical framework of the system; (b) the Human Movement response, M; and (c) the shading responses--light shading, c'R, and dark shading, c'R. The reader is also introduced to other works by Piotrowski, including scales for cerebral dysfunction and schizophrenia.
