introversion

n. turning inward, state of being turned inward; inner contemplation, tendency to focus on one's inner thoughts and feelings (Psychology)

The trait of Extraversion-Introversion is a central dimension of human personality. Extraverts (sometimes called "extroverts") are gregarious, assertive, and generally seek out excitement. Introverts, in contrast, are reserved, thoughtful, and self-reliant. They are not necessarily asocial, but they tend to have smaller circles of friends, and are less likely to thrive on making new social contacts.
