2. Perceiving function is extraverted - curious, empirical, adaptable: Perceiving Types

Function Method

Primary: the function you use the most and are most comfortable with

Auxiliary: complements your primary and is used quite often as well

Tertiary: less developed and takes longer to mature 

Inferior: matures latest in life, unconscious, and it can be especially troublesome because you might be less aware of it or have trouble understanding how it works.
