Book excerpt: A Student’s Dictionary of Psychology is an essential reference for all undergraduate psychology students and those studying psychology for the first time, including those in related disciplines such as health care and social science. It provides the reader with clear definitions of key concepts from all areas of psychology. This new edition of A Student’s Dictionary of Psychology adopts a slightly different format and extended content to previous editions, but it continues to be an ‘explaining’ dictionary rather than simply a set of one-line definitions. Following up all the references and cross-references relating to a topic should give the reader a reasonable overview of the subject; in that sense, the authors have often referred to it as a kind of random-access textbook, as well as a dictionary of the main terms in psychology. Key features include: Over 2,400 entries in total; Extensive cross referencing for easy navigation; Mini biographies of key psychologists; Common abbreviations and a list of key reference works; Study notes section. This new edition includes increased coverage of psychoneurology, social, clinical, and cognitive psychology, and research methodology, as well as several other terms which have come into common usage in recent years. It also includes a list of common abbreviations, and expanded coverage of significant figures in the history of psychology. This comprehensive dictionary will support the reader all the way through their psychology studies.
