Cognitive Functions

Carl Jung theorized that everyone has four essential mental functions or "cognitive processes". We take in and process information through our "perceiving" functions, which Jung called sensing (S) and intuition (N). We then make decisions using our "judging" functions, which Jung called thinking (T) and feeling (F) (not to be confused with emotion).

Jung further theorized that each function operates in two orientations or "worlds" - the internal (introverted, I) world of ideas, memories, and imagination and the external (extraverted, E) world of actions, people, and organizations.

By combining four mental processes with two orientations each, we get eight cognitive functions.

down Orientation
Perceiving Judging

Ne

Te

Fe
Introverted Sensing
Si

Ni

Ti

Fi

Note that we use the letter N to represent "iNtuition", to distinguish the abbreviation from Introversion.

The cognitive functions are used and displayed differently in each Psychological Type. These differences in how people perceive information and make decisions about it account for the differences between each personality type.

Each Type has a dominant function (the strongest and most natural, preferred, function) supported by an auxiliary function. The 3rd (tertiary or relief) and 4th (inferior or aspirational) functions are developed later in life. Functions 5 through 8 develop even more slowly or come out when the individual is under stress.

Although it may seem at first glance that two personality types differ by "only one letter", that one letter can represent a large difference in the order of a Type's functions and how they are presented in an individual person, particularly in their Temperament and Interaction Style.
