The present study explored emotional thinking in the adult using four related scales. A new Mysticism Scale assessed tendencies to use magical, esoteric, incomprehensible, and unfounded concepts and hypotheses. Two related scales (Paranormal Belief, Magical Ideation) correlated .88 and .74, respectively, with the Mysticism Scale. The Globality-Differentiation Scale assessed emotional, subjective, and centered thinking and related to unpleasant, arousable, and submissive characteristics, showing it to be the cognitive counterpart of Trait Anxiety or Neuroticism. The Globalityl maladjustment relationship was confirmed by positive relationships of the Globality Scale with measures of Trait Anxiety, Depression, Panic, Somatization, and Drug Use. In comparison, the Mysticism Scale related only to Trait Arousability (a measure of positive and/or negative emotional sensitivity) and, along with the Paranormal Belief and Magical Ideation scales, was generally unrelated to measures of psychopathology.Werner defined development as involving progressive differentiation and hierarchic integration of parts and used this definition to analyze cognitive systems (or world views) of 1) individuals or 2) cultures [l}. For individuals, Werner's definition of development implied less self-other differentiation and greater fusion of cognition, affect, and behavior at earlier stages of development. Shared 325
