A taxonomy of Rorschach autisms with implications for differential diagnosis among thinking-disordered patients

Area of Science:

• Psychological assessment
• Psychopathology
• Cognitive processes

Background:

• The Rorschach test is a projective psychological test used to assess personality characteristics and emotional functioning.
• Perceptual-cognitive errors on the Rorschach can provide insights into thought disorders.
• A tripartite taxonomy of perceptual-cognitive errors, TRAUT, categorizes these errors.

Purpose of the Study:

• To review the tripartite taxonomy of perceptual-cognitive errors (TRAUT) on the Rorschach.
• To investigate the utility of specific TRAUT categories (HYPO, HYPER, RELER) in identifying thought disorders.
• To determine if HYPO and HYPER scores can serve as a routine screen for thought disorder.

Main Methods:

• Reviewed the tripartite taxonomy of perceptual-cognitive errors (TRAUT).
• Examined Rorschach records of inpatient and outpatient schizophrenics, borderline personality disorders, and Cluster A personality disorders.
• Scored HYPO (disregard for blot shapes) and HYPER (attention to unusual blot areas) errors and analyzed their frequency.

Main Results:

• HYPO and HYPER errors showed better diagnostic differentiation among the studied groups compared to RELER errors.
• These findings suggest HYPO and HYPER are valuable indicators of thought disorder.
• RELER errors were less effective in differentiating the groups.

Conclusions:

• The HYPO and HYPER categories of TRAUT are promising indicators for screening thought disorders.
• Routine scoring of HYPO and HYPER on the Rorschach may aid in the early identification of thought disorder.
• Further research is warranted to validate these findings.
