<P> The dynamic sequence of functions and their attitudes can be determined in the following way: </P> <Ul> <Li> The overall lifestyle preference (J-P) determines whether the judging (T-F) or perceiving (S-N) preference is most evident in the outside world; i.e., which function has an extraverted attitude </Li> <Li> The attitude preference (E-I) determines whether the extraverted function is dominant or auxiliary </Li> <Li> For those with an overall preference for extraversion, the function with the extraverted attitude will be the dominant function . For example, for an ESTJ type the dominant function is the judging function, thinking, and this is experienced with an extraverted attitude . This is notated as a dominant Te . For an ESTP, the dominant function is the perceiving function, sensing, notated as a dominant Se . </Li> <Li> The auxiliary function for extraverts is the secondary preference of the judging or perceiving functions, and it is experienced with an introverted attitude: for example, the auxiliary function for ESTJ is introverted sensing (Si) and the auxiliary for ESTP is introverted thinking (Ti). </Li> <Li> For those with an overall preference for introversion, the function with the extraverted attitude is the auxiliary; the dominant is the other function in the main four letter preference . So the dominant function for ISTJ is introverted sensing (Si) with the auxiliary (supporting) function being extraverted thinking (Te). </Li> <Li> The tertiary function is the opposite preference from the auxiliary . For example, if the Auxiliary is thinking then the Tertiary would be feeling . The attitude of the tertiary is the subject of some debate and therefore is not normally indicated; i.e. if the auxiliary was Te then the tertiary would be F (not Fe or Fi) </Li> <Li> The inferior function is the opposite preference and attitude from the Dominant, so for an ESTJ with dominant Te the inferior would be Fi . </Li> </Ul> <Li> The overall lifestyle preference (J-P) determines whether the judging (T-F) or perceiving (S-N) preference is most evident in the outside world; i.e., which function has an extraverted attitude </Li> <Li> The attitude preference (E-I) determines whether the extraverted function is dominant or auxiliary </Li>
