Margaret Harris was educated at Northampton School for Girls and Kettering High School. She gained her BSc in Psychology at Bedford College and her PhD at Birkbeck College, University of London. Margaret lectured at Birkbeck College and then became a Senior Lecturer and subsequently a Reader at Royal Holloway University of London. Her main research interests are in language development and reading, with an emphasis on the cognitive development of deaf children.Margaret is involved in several research projects investigating the early language development of children with severe/profound deafness. Her research has looked at the development of successful communication between deaf infants and their mothers and the implications of this for early sign and oral language development. She is particularly interested in the development of visual attention between deaf infants and their mothers and how this relates to early language development.George Butterworth (1946-2000) completed a D.Phil at Oxford University after which he took up a teaching post at Southampton University. This was followed by a Chair in Psychology at Stirling University. He became a Professor at Sussex University in 1991.George was an authority on infant development and the origins of thought and perception in infants. His research interests were broad, encompassing topics as varied as the origins of self-awareness in human development and evolution, and children's understanding of geographical features of the earth.George founded both the British Infancy Research Group and the journal Developmental Science. He was the first president of the European Society for Developmental Psychology and a former president of the British Psychological Society, Developmental Section. He was internationally respected for his scholarship and commitment to research.

"An up-to-date account of developmental psychology written by two major authorities in the field ... All in all, it is an authoritative and clear treatment of developmental psychology that will appeal to undergraduates who are just beginning to study developmental psychology, as well as those who already have some grounding in the subject." - Dr Gavin Bremner, Lancaster University, UK "Developmental Psychology is an exciting and fast-moving subject, but one that is hard to summarise because it involves such a variety of questions, and hypotheses, and research methods. Yet Margaret Harris and George Butterworth have been completely successful in producing a coherent and wonderfully stimulating account of the subject as a whole. Undergraduate students will learn a great deal from this book, and they will enjoy reading it as well. So will parents, teachers and any one else interested in childhood." - Professor Peter Bryant FRS, Oxford University, UK "A useful developmental textbook ideally pitched at undergraduate level developmental psychology. The writing style is clear and easy to read with the right level of detail when describing influential empirical work." - Dr Alyson Davis, University of Surrey, UK "This is an impressive book. It is a beautifully written, up-to-date, and well balanced account of the development of the child from conception to adolescence." - Dr Alan Slater, University of Exeter, UK
