The document summarizes the Johari Window model of interpersonal communication and relationships. The Johari Window consists of four quadrants representing what a person knows about themselves (open and hidden areas) and what others know about them (open and blind areas). The goal is to increase the open area through self-awareness, feedback, and disclosure to improve understanding between individuals. The model uses a series of questions to help people understand their own behaviors and how others perceive them in order to reduce blind spots and the unknown area.
