'Social psychology' provides the only conceptually integrated undergraduate introduction to social psychology, offering a clear synthesis of the cognitive and social, and individual and group influences that shape social behavior. This textbook offers comprehensive coverage of classic, contemporary, and emerging topics in social psychology. The focus is on underlying, unifying principles that operate across topics, rather than treatment of each topic in isolation, a focus that reflects the increasingly cross-disciplinary developments within and beyond psychology. An emphasis on research carried out in different parts of the world and a sensitivity to cross-cultural perspectives highlights the internationalization of the field in recent years. In addition, the text offers real-world applications of scientific principles to areas such as marketing, law, education, and health. Throughout, the discussion conceptually integrates the pervasive impact of social groups on all aspects of social behavior.
