Introversion

Introversion is psychological trait first fully established by the Swiss psychiatrist Carl Gustav Jung, which has since been applied and mentioned in several psychological instruments and systems.

As cognitive orientation
"See Analytical Psychology"

As a personality trait
People generally characterized as "introverted" are said to spend time alone rather than with others, although such a description is better referential of general withdrawal/reservation, rather then introversion as a whole. One complete and empirically produced collection of traits (hereby called "facets") composing introversion was constructed by the now incredibly common Big Five personality traits (also called the Five Factor Model).
