Reductio ad absurdum: a formal analysis of Rorschach autisms.

Generalizing from the rationales underlying the scoring of the three types of Rorschach autisms included in the TRAUT system, it was shown that all perceptual autisms can be subsumed under a single, all-encompassing principle based upon a reductio ad absurdum argument. Therefore, in a way, autisms can be viewed as "cheating," i.e., getting around the explicit and implicit rules governing the evaluation of Rorschach percepts.
