The first edition of this book outlined what amounted to a breakthrough in the analysis of social behaviour. Since then it has become widely used as an introductory textbook of social psychology. It is invaluable to anyone interested in the subject or whose work involves dealing with people, as well as anyone who wants to know how to make friends and influence people. For this new, fifth edition, Michael Argyle includes the latest research on non-verbal communication, social skills and happiness.
