Introversion is a personality trait described in several different theories of personality. It is usually described in contrast to extraversion, with both traits representing opposite ends of the same dimension. While extraversion is characterized by sociability, talkativeness and assertiveness, introversion involves being more focused on internal thoughts and experiences.
Unlike extraverts, introverts do not need to seek out external stimulation. They are inward turning, meaning that they are focused on the inner world of thoughts, feelings and emotions. While extraverts gain energy from socializing, introverts must expend energy while interacting with other people. For example, after attending a holiday party, an introvert might feel a need to spend some time alone in order to "recharge."
