Carl Jung Psychological Types

Psychological Types is the sixth volume in the Princeton / Bollingen edition of the Collected Works of Carl Jung. The original German language edition, Psychologische Typen, was first published by Rascher Verlag, Zurich in 1921. In the book Jung categorized people into primary types of psychological function.

Jung proposed four main functions of consciousness:

Two perceiving functions: Sensation and Intuition
Two judging functions: Thinking and Feeling
The functions are modified by two main attitude types: extraversion and introversion. Jung theorized that the dominant function characterizes consciousness, while its opposite is repressed and characterizes unconscious behavior.

The eight psychological types are as follows:

Extraverted sensation
Introverted sensation
Extraverted intuition
Introverted intuition
Extraverted thinking
Introverted thinking
Extraverted feeling
Introverted feeling
