Publisher's Synopsis
Psychological research relies on a wide range of methods. This is partly because it is such a diverse discipline, ranging from biological aspects of behaviour to social psychology and from basic research questions that arise in such applied fields as clinical and educational psychology.;The Longman Essential Psychology series provides comprehensive and concise coverage of all the major topics studied in undergraduate psychology courses throughout the UK, Europe and the USA. Each volume deals with a core module and is written by an international list of contributors who are all actively involved in research.
