From their location in the heart of Detroit, Michigan, the Weisfelds' lab has reached out for thirty years to couples in long-term partnerships around the world. In living rooms of Detroit, London, Moscow, Beijing, and beyond, couples of all types and ages have shared their insights into adult romantic relationships. This book, The Psychology of Marriage, is a distillation of these findings, which have appeared in dozens of book chapters, journal articles, and conference presentations. The book also provides new systematic comparisons that offer insights into the mysteries of marriage and other committed relationships. Scholars, professional counselors, and family therapists will find a helpful framework for thinking about cultural similarities and differences in marital dynamics. Researchers will be introduced to a robust new instrument, the Marriage and Relationship Questionnaire (MARQ), which can be used in heterosexual and same-sex couples in virtually any cultural setting, along with ethical guidelines for conducting this research. Anyone who is interested in why committed relationships work (or do not work) will find the book filled with compelling new insights.

Psychological research has produced a rich body of empirical data documenting humanity's propensity to commit infidelity in the context of long-term relationships, but comparatively little work has been dedicated to synthesizing these data into an integrated framework that encompasses the full range of its processes, from why it occurs in the first place to how it affects the long-term relationship thereafter. This edited handbook integrates a broad range of topics such as characteristics related to the propensity to commit infidelity, sex differences in reactions to infidelity, our inclination to dissolve relationships after infidelity, and other responses to infidelity. It showcases contributions from experts in social psychology, evolutionary psychology, and others who specialize in research on romantic relationships. The handbook discusses the processes of infidelity alongside sources of variation, such as sexual orientation, developmental life history, individual differences, and culture. This volume captures the interdisciplinary quality of research on the predictors, nature, and consequences of infidelity for the broader social scientific community interested in trust in romantic relationships.
