This document discusses the Social Penetration Theory and how it applies to relationships within a collegiate women's soccer team. The Social Penetration Theory proposes that relationships develop over time through reciprocal self-disclosure, from surface level facts to deeper, more intimate disclosures. As with an onion, people have layers of information that get peeled back through self-disclosure. For a team to be successful, players must develop close relationships through balancing breadth and depth of communication. Applying this theory, soccer players disclose more personal information to teammates as they spend extensive time together, developing close relationships that aid team chemistry and performance.
