Divorce rates are at an all-time high. But without a theoretical understanding of the processes related to marital stability and dissolution, it is difficult to design and evaluate new marriage interventions. The Mathematics of Marriage provides the foundation for a scientific theory of marital relations. The book does not rely on metaphors, but develops and applies a mathematical model using difference equations. The work is the fulfillment of the goal to build a mathematical framework for the general system theory of families first suggested by Ludwig Von Bertalanffy in the 1960s.The book also presents a complete introduction to the mathematics involved in theory building and testing, and details the development of experiments and models. In one "marriage experiment," for example, the authors explored the effects of lowering or raising a couple's heart rates. Armed with their mathematical model, they were able to do real experiments to determine which processes were affected by their interventions. Applying ideas such as phase space, null clines, influence functions, inertia, and uninfluenced and influenced stable steady states (attractors), the authors show how other researchers can use the methods to weigh their own data with positive and negative weights. While the focus is on modeling marriage, the techniques can be applied to other types of psychological phenomena as well.

A guide to the mathematical modeling of marriage.

"A mathematician pulls back the curtain and reveals the hidden patterns--from dating sites to divorce, sex to marriage--behind the rituals of love ... applying mathematical formulas to the most common yet complex questions pertaining to love: What's the chance of finding love? What's the probability that it will last? How do online dating algorithms work, exactly? Can game theory help us decide who to approach in a bar? At what point in your dating life should you settle down?"--Amazon.com.

Marital Interaction: Experimental Investigations deals with experimental studies on marital interaction. Emphasis is on the importance of the role of description in the study of social interaction. Methods for the analysis of pattern and sequence, including cross-spectral time-series analysis, are also presented. Comprised of 15 chapters, this book begins with a historical review of several research traditions that have concerned themselves with families and marriages: the sociological tradition; the family therapy or systems tradition; the social learning tradition; and the developmental tradition. Research that points to the potential importance of the observation of consensual decision-making processes is also reviewed. A model of marital interaction called the Structural Model, which can be used to predict changes in marital satisfaction, is described. Subsequent chapters focus on the Couples Interaction Scoring System, an observational system for categorizing marital interaction; modern concepts of the assessment of reliability, particularly the stringent assessment that is necessary for sequential analysis; differences between well-functioning and poorly functioning marriages; couples' interactional styles in terms of communication skill deficits; and the concept of an individual's social competence. This monograph will be of interest to psychologists engaged in research on marriage, as well as sociologists and clinical researchers.

The definitive anthology of wisdom and wit about one of life’s most complex, intriguing, and personal subjects. When and whom do you marry? How do you keep a spouse content?
