The effect of the law on human behavior is contemporary society-nothing less is the concern of this important book. It is curious that scholars in psychology and law have largely neglected this topic because studies of the effects of law on behavior may have much to teach about the role of social regulation in human motivation more generally. Similarly, such studies may offer jurisprudential scholars new ways of thinking about the role of law in human experience. Here seven leading experts on law and the social sciences discuss the contributions their research c an make to the legal system. Concerned with the relationship between the law and both individual and group behavior, they examine the law as an instrument of social stasis and social change and as an element of personal motivation. The result is a major step toward the development of a psychology of jurisprudence. The scope of this book is in the best tradition of the Nebraska Symposium on Motivation and a fitting celebration of the tenth anniversary of the University of Nebraska-Lincoln's Law/Psychology Program, the first integrated graduate training program in psycho-legal studies. Drawing from law, anthropology, sociology, psychology, and philosophy, the contributors take a truly interdisciplinary approach to understanding the instrumentality of law.
