The Benchmark Series brings together the key publications of leading psychologists from right across the discipline. Each volume is edited by the author or a close colleague and includes a full bibliography of the work of the author and a brief biography. An introduction reviews the contribution of the work and sets it in its historical and intellectual context. The books will be invaluable adjuncts to many undergraduate courses in psychology, bringing the discipline alive through a deeper understanding of the people who are shaping it. Psychologists specialising in the areas covered by a particular author will find them to be of especial value.
