In relationships, which concept explains how putting more time, effort, and emotional support into the partnership tends to increase commitment over time?

• A. Investments in relationships
• B. Quality of alternatives
• C. Paternity uncertainty
• D. Self-expansion theory

Answer: (A)

The main idea is that when you invest more in a relationship—spending time, energy, and emotional support—you create resources and bonds that make leaving feel costly. This is a core idea of the Investment Model of Commitment: the more you’ve put into the relationship, the more you stand to lose if it ends, so commitment tends to rise over time as investments grow. These investments can include shared routines, memories, and mutual support, which become part of what you’d forfeit by breaking up. Other concepts don’t capture this mechanism as directly. Quality of alternatives focuses on what you might gain outside the relationship, not on how existing investments keep you committed. Paternity uncertainty is about biology and offspring-related considerations, not daily relationship commitment. Self-expansion theory describes how relationships help you grow as a person, but it doesn’t specifically explain how accumulating time and resource commitments increase commitment itself.
