Attitudes: extraversion/introversion (E/I)
Myers-Briggs literature uses the terms extraversion and introversion as Jung first used them. Extraversion means “outward-turning” and introversion means “inward-turning”. These specific definitions vary somewhat from the popular usage of the words.
The preferences for extraversion and introversion are often called attitudes. Briggs and Myers recognized that each of the cognitive functions can operate in the external world of behavior, action, people, and things (extraverted attitude) or the internal world of ideas and reflection (introverted attitude). The MBTI assessment sorts for an overall preference for one or the other.
People who prefer extraversion draw energy from action: they tend to act, then reflect, then act further. If they are inactive, their motivation tends to decline. To rebuild their energy, extraverts need breaks from time spent in reflection. Conversely, those who prefer introversion expend energy through action: they prefer to reflect, then act, then reflect again. To rebuild their energy, introverts need quiet time alone, away from activity.
The extravert’s flow is directed outward toward people and objects, and the introvert’s is directed inward toward concepts and ideas. Contrasting characteristics between extraverts and introverts include the following:
[LIST]
[]Extraverts are action oriented, while introverts are thought oriented.
[]Extraverts seek breadth of knowledge and influence, while introverts seek depth of knowledge and influence.
[]Extraverts often prefer more frequent interaction, while introverts prefer more substantial interaction.
[]Extraverts recharge and get their energy from spending time with people, while introverts recharge and get their energy from spending time alone.

Functions: sensing/intuition (S/N) and thinking/feeling (T/F)
Jung identified two pairs of psychological functions:
[LIST]
[]The two perceiving functions, sensing and intuition
[]The two judging functions, thinking and feeling
[/LIST]
According to the Myers-Briggs typology model, each person uses one of these four functions more dominantly and proficiently than the other three; however, all four functions are used at different times depending on the circumstances.
Sensing and intuition are the information-gathering (perceiving) functions. They describe how new information is understood and interpreted. Individuals who prefer sensing are more likely to trust information that is in the present, tangible and concrete: that is, information that can be understood by the five senses. They tend to distrust hunches, which seem to come “out of nowhere”. They prefer to look for details and facts. For them, the meaning is in the data. On the other hand, those who prefer intuition tend to trust information that is more abstract or theoretical, that can be associated with other information (either remembered or discovered by seeking a wider context or pattern). They may be more interested in future possibilities. They tend to trust those flashes of insight that seem to bubble up from the unconscious mind. The meaning is in how the data relates to the pattern or theory.
Thinking and feeling are the decision-making (judging) functions. The thinking and feeling functions are both used to make rational decisions, based on the data received from their information-gathering functions (sensing or intuition). Those who prefer thinking tend to decide things from a more detached standpoint, measuring the decision by what seems reasonable, logical, causal, consistent and matching a given set of rules. Those who prefer feeling tend to come to decisions by associating or empathizing with the situation, looking at it ‘from the inside’ and weighing the situation to achieve, on balance, the greatest harmony, consensus and fit, considering the needs of the people involved. Thinkers usually have trouble interacting with people that are inconsistent or illogical, and tend to give very direct feedback to others. They are concerned with the truth and view it as more important than being tactful.
Lifestyle: judging/perception (J/P)
Myers and Briggs added another dimension to Jung’s typological model by identifying that people also have a preference for using either the judging function (thinking or feeling) or their perceiving function (sensing or intuition) when relating to the outside world (extraversion).
Myers and Briggs held that types with a preference for judging show the world their preferred judging function (thinking or feeling). So TJ types tend to appear to the world as logical, and FJ types as empathetic. According to Myers, judging types like to “have matters settled”.
Those types who prefer perception show the world their preferred perceiving function (sensing or intuition). So SP types tend to appear to the world as concrete and NP types as abstract. According to Myers, perceptive types prefer to “keep decisions open”.
For extraverts, the J or P indicates their dominant function; for introverts, the J or P indicates their auxiliary function. Introverts tend to show their dominant function outwardly only in matters “important to their inner worlds”. For example:
Because ENTJ types are extroverts, the J indicates that their dominant function is their preferred judging function (extraverted thinking). ENTJ types introvert their auxiliary perceiving function (introverted intuition). The tertiary function is sensing and the inferior function is introverted feeling.
Because INTJ types are introverts, the J indicates that their auxiliary function is their preferred judging function (extraverted thinking). INTJ types introvert their dominant perceiving function (introverted intuition). The tertiary function is feeling, and the inferior function is extraverted sensing.
