Social Penetration Theory (Definition & Easiest Explanation)

Social penetration theory is a psychological and communication theory that explains the development of interpersonal relationships through a gradual process of self-disclosure. Proposed by Irwin Altman and Dalmas Taylor in 1973, the theory likens interpersonal relationships to an onion, with multiple layers representing different levels of intimacy in communication. As individuals engage in deeper discussions, they peel back these layers, revealing more personal thoughts, feelings, and experiences. Ultimately, the theory suggests that meaningful relationships grow through increased intimacy, allowing partners to foster trust and understanding over time.
