Final answer:
Communication is at the heart of every quality relationship, integral to developing intimacy, passion, and commitment as outlined in Sternberg's triangular theory of love.
Step-by-step explanation:
At the heart of every quality relationship is communication, according to various theories and research findings in social psychology. While Robert Sternberg's triangular theory of love identifies intimacy, passion, and commitment as components of consummate love, the essence of quality in relationships lies in the ability to communicate effectively. This is reinforced by research which shows that communication, particularly voice conversation over text messaging, leads to stronger emotional bonds and a higher satisfaction within relationships. Social Exchange Theory also underscores the importance of perceived benefits over costs in maintaining relationships, but this doesn't negate the requisite of good communication as a fundamental element for relationship quality. Without communication, it is challenging to develop intimacy, share passion, and sustain commitment—integral parts of Sternberg's concept of consummate love.
