This document summarizes key concepts about interpersonal communication and the self from a chapter in a textbook. It discusses how an individual's self-concept develops based on feedback and comparisons to others, and how one presents themselves publicly versus privately. Impression management involves deciding what parts of oneself to reveal in different contexts. Models of self-disclosure, like the Social Penetration Model, show how intimacy in relationships grows as people share more personal information over time. While self-disclosure can strengthen relationships, it also carries risks that must be weighed. The document provides guidelines for effective self-disclosure and alternatives like silence when disclosure may not be appropriate.
