Introverts process information internally, and we don't like to express our thoughts until they are fully formed.
Laurie HelgoeAn introvert may feel asocial when pressured to go to a party that doesn't interest her. But for her, the event does not promise meaningful interaction. In fact, she knows that the party will leave her feeling more alone and alienated.
Laurie HelgoeWhen an introvert cares about someone, she also wants contact, not so much to keep up with the events of the other person's life, but to keep up with what's inside: the evolution of ideas, values, thoughts, and feelings.

Laurie HelgoeExtroverts are more attuned to social rewards, so they are more likely to flash a smile for effect. A notable exception are introverts - like me - whom I call "socially accessible" introverts. We have been trained well to smile and nod, which can place a burden on our processing efforts.
