Reductio ad absurdum: a formal analysis of Rorschach autisms

Area of Science:

• Psychological assessment
• Personality testing
• Psychometrics

Background:

• The Rorschach test is a projective psychological test used to assess personality characteristics and emotional functioning.
• Scoring Rorschach responses involves complex rules to interpret perceptual and cognitive processes.
• Previous systems have identified various types of perceptual autisms within Rorschach scoring.

Purpose of the Study:

• To generalize the scoring rationales of Rorschach autisms within the TRAUT system.
• To establish a unifying principle for all perceptual autisms in Rorschach interpretation.
• To reframe the understanding of Rorschach autisms as a deviation from established scoring rules.

Main Methods:

• Analysis of scoring rationales for three types of Rorschach autisms in the TRAUT system.
• Application of a reductio ad absurdum argument to identify an overarching principle.
• Conceptual generalization across different forms of perceptual autism.

Main Results:

• All perceptual autisms within the Rorschach scoring system can be encompassed by a single, overarching principle.
• This principle is derived from a reductio ad absurdum logical argument.
• Rorschach autisms can be conceptualized as a method of circumventing the explicit and implicit rules of percept evaluation.

Conclusions:

• A unified theoretical framework for understanding Rorschach autisms has been proposed.
• The findings suggest that perceptual autisms represent a systematic departure from normative Rorschach scoring.
• This perspective offers a novel way to interpret scoring deviations in Rorschach assessments.
