Each type has a cognitive functions stack that denotes a descending order of dominance and conscious awareness. So combined with the primary E/I function these are: Ne/Ni Extraverted/Introverted Intuition, Fe/Fi Extraverted/Introverted Feeling, Te/Ti Extraverted/Introverted Thinking and Extraverted/Introverted Sensing. Depending on the order of the stack each personality type will lead with one primary function working in tandem with the second auxiliary position. The tertiary function has less influence and the fourth functions is an opposite of the first.
This can all get a bit confusing so included below is a visual graphic of how all the functions fit into the matrix.
