Martin L. Hoffman is an American psychologist, a professor emeritus of clinical and developmental psychology at New York University.

Contemporary theories have generally focused on either the behavioral, cognitive or emotional dimensions of prosocial moral development. In this volume, these three dimensions are brought together while providing the first comprehensive account of prosocial moral development in children. The main concept is empathy - one feels what is appropriate for another person's situation, not one's own. Hoffman discusses empathy's role in five moral situations. The book's focus is empathy's contribution to altruism and compassion for others in physical, psychological, or economic distress. Also highlighted are the psychological processes involved in empathy's interaction with certain parental behaviors that foster moral internalization in children and the psychological processes involved in empathy's relation to abstract moral principles such as caring and distributive justice. This important book is the culmination of three decades of study and research by a leading figure in the area of child and developmental psychology.
