<P> Drawing upon Jungian theory, Isabel Myers proposed that for each personality type, the cognitive functions (sensing, intuition, thinking, and feeling) form a hierarchy . This hierarchy represents the person's default pattern of behavior . </P> <P> The Dominant function is the personality type's preferred role, the one they feel most comfortable with . The secondary Auxiliary function serves to support and expand on the Dominant function . If the Dominant is an information gathering function (sensing or intuition), the Auxiliary is a decision making function (thinking or feeling), and vice versa . The Tertiary function is less developed than the Dominant and Auxiliary, but it matures over time, rounding out the person's abilities . The Inferior function is the personality type's fatal weakness . This is the function they are least comfortable with . Like the Tertiary, the Inferior function strengthens with maturity . </P>
