MBTI cognitive functions
The attributes of each personality form a hierarchy. This represents the person's "default" pattern of behavior in their day to day life. The Dominant is the personality type's preferred role, the task they feel most comfortable with. The auxiliary function is the role they feel the next most comfortable with. It serves to support and expand on the dominant function. One of these first two will always be an information gathering function (sensing or intuition) and the other will be a decision making function(thinking or feeling) in some order. The tertiary function is less developed than the Dominant and Auxiliary functions, but develops as the person matures and provides roundness of ability. The inferior function is the personality types Achilles' heel. This is the function they are least comfortable with. Like the tertiary function, this function strengthens with maturity.
