Book excerpt: Positive Social Behavior and Morality: Social and Personal Influences, Volume I presents the broad range of influences that encourage or inhibit people to behave positively towards others and how varied forms of positive behavior are determined. The book examines the various aspects of positive social behavior. It starts by providing the definition, significance, and relationship of positive or prosocial behavior to morality. Topics on why people behave prosocially; the determinants of people helping other people in physical distress; effects of harm doing on prosocial behavior; the limitations of current methods; the goals for future study in the field of prosocial behavior; and a theoretical model for predicting prosocial behavior are presented as well. Psychologists, sociologists, researchers, and students in the field of sociology and psychology will find this book interesting.
