A Commentary on DeCato's "On the Rorschach M Response and Monotheism" (1993)

In a recent article, DeCato (1993) posits a fundamental dichotomy between the Comprehensive System (Exner, 1986) Rorschach interpretation, which is based on group norms, and the Perceptanalytic System (Piotrowski, 1957), which advocates validating Rorschach microfacts against the behavior of the individual. Perspective can be gained on this issue by recognizing that these approaches are actually extremes on a continuum where interpretation gradually narrows from the general to the specific. Acknowledging the funnel-shaped character of Rorschach interpretive approaches tins implications for understanding, scoring, and teaching projective techniques.
