Mental boundaries as a new dimension of personality: A comparison of Hartmann's boundaries in the mind and Jung's psychological types

Ernest Hartmann's (1989) thick and thin boundaries are compared to Carl Jun g's (1971) psychological types using Hartmann's boundaries questionnaire an d the Myers-Briggs Personality Type Indicator. Multiple regression showed s mall correlations between Hartmann's boundary dimension and two of the four MBTI dimensions (sensing-intuitive and thinking-feeling). ANOVA demonstrat ed that boundaries scores differed for three of the four MBTI subscales (se nsing-intuitive, thinking-feeling, and judging-perceiving). Results suggest that the thinking-feeling dimension is the most closely related to boundar ies in the mind. Given the overall low relationships between boundaries in the mind and Jung's psychological types, it appears that the boundary quest ionnaire measures a personality dimension unique from those measured on the MBTI. Future research is also discussed.
