11 implied the existence of this dimension. Basically it describes whether a person prefers to use judgment or perception in dealings with the world. According to Myers, "This preference makes the difference between the judging people who order their lives and the perceptive people who just live them" (Myers, 1980, p. 9). McCaulley (1981) summarized the four preferences in Advances in Psychological Assessment, reproduced with the author's permission in Table 1-3. According to Jung's theory, one of the four functions (sensing, intuition, thinking, or feeling) becomes the dominant function and provides direction and stability to the personality. If the dominant function is a perceptive function (sensing or intuition), it will be balanced by development of one of the judgment functions (thinking or feeling). This second function is known as the auxiliary function. Further balance in the personality is provided by the theoretical assumption that for extraverts, the dominant function will be used mainly in interactions with the outside world, while the auxiliary is used mainly in the inner world of concepts and ideas. For introverts, on the other hand, the dominant function is used mainly in the inner world of concepts and ideas while the auxiliary is used with the outside world. Each of the Jungian types has its own special relationships postulated between the developed functions and the extraverted and introverted attitudes (Myers & McCaulley, 1985). Coping Styles Coping styles, measured by the Millon Behavioral Health Inventory, were derived from Millon's biosocial theory of personality development.
