From Cupid to the chromosome, this is an introduction to the social-psychological literature on romantic relationships. It draws on a wide range of scientific findings and psychological perspectives, including reinforcement-equity theory, cognitive-attribution theory, personality-trait theory, attachment theory, and socio-biology, all of which play a part in providing an understanding of the nature of contemporary romantic relationships. The authors also develop the concepts of attachment, intimacy and passion, and study the effects and roles of shyness, loneliness, break-ups, words, deeds, context and environment. Offering a wealth of anecdotes and detailed examples, the book aims to distil the complex issues of romantic relationships and communicate their inner workings.
