This book provides a diverse collection of studies reporting the effects of social influence processes in multiple cultures at both the universal and culture-specific levels. The book is characterized by three distinct features. First, the social influence process is considered as a ubiquitous and pervasive feature of human interaction. Second, the book represents a multicultural approach which includes both cross-cultural and culture-focused examinations. Third, the book emphasizes practical implications of the research presented. This volume incorporates theory and research stemming from three different approaches to social influence: social influence principles across cultures, social influence and social change across cultures, and culture and moral perspective in the social influence process. Because each of these three parts encompasses a considerable variety of research methodologies, social contexts, and cultures, each is proceeded by an integrative commentary authored by one of the book editors. These essays provide syntheses of the topics and themes within the corresponding sections and within the book as a whole. They also offer critical commentaries on both theoretical and methodological issues, raise suggestions for future research, and focus on practical applications. This book is intended for both scholars interested in cross- and multicultural research into the mechanisms of the social influence process and for the professional whose mission is to make planned changes in a society. Knowledge about the influence process, especially regarding how it works in different cultures and within several cultural groups, facilitates this goal. The practical implications ending each chapter serve as encouraging instructions for such applications.
