In particular, the “Cognitive Quartet of Rorschach scores”, for use in psychiatric-forensics. In fact, the 70.0% threshold of R +% and F +% makes it possible, in practice, to discriminate very high among imputable and non- imputable subjects, with undoubted consequences on the practical exercise of psychology and forensic psychiatry.
