Applied Social Psychology combines the science of social psychology with the practical application of solving social problems that exist in the real world. This exciting textbook provides a thorough explanation of how social psychologists can contribute to the understanding and management of different social problems. A highly prestigious team of contributors from across Europe and the United States illustrate how social psychological theories, research methods and intervention techniques can be successfully applied to problems encountered in the fields of physical and mental health, immigration and integration, economic behaviour, political behaviour, environmental behaviour, organisations and the classroom. This expanded edition also features new chapters on the dynamic fields of consumer behaviour, traffic behaviour, criminal behaviour, sport and development aid. Each field studied features an overview of important problems, the role of human behaviour in these problems, the factors influencing relevant behaviour, and effective ways to change this behaviour. This is an essential volume for all undergraduate and graduate students studying applied social psychology.
