Noting that the last 30 years have seen enormous increases in the understanding of infancy, this book examines the current state of knowledge regarding infant development. The book's contents stem from meetings of the British Infancy Research Group. Although the book was intended for advanced undergraduates, it would also be useful for advanced researchers. The chapters are: (1) "Development of Taste Perception and Appetite Regulation" (Gillian Harris); (2) "Visual Perception and Its Organisation in Early Infancy" (Alan Slater); (3) "From Perception to Cognition" (J. Gavin Bremner); (4) "Dynamical Systems Approaches to the Development of Action" (Brian Hopkins and George Butterworth); (5) "Beyond the 'Couch Potato' Infant: How Infants Use Their Knowledge To Regulate Action, Solve Problems, and Achieve Goals" (Peter Willatts); (6) "Reassessing Piaget's Theory of Sensorimotor Intelligence: A View from Cognitive Science" (Julie C. Rutkowska); (7) "Development of Categorisation: Perceptual and Conceptual Categories" (Jean M. Mandler); (8) "Stability of Mental Development from Infancy to Later Childhood: Three 'Waves' of Research" (Marc H. Bornstein, Alan Slater, Elizabeth Brown, Elizabeth Roberts, and Jacqueline Barrett); (9) "Perception of Social Stimuli: Face Perception and Imitation" (Alan Slater and George Butterworth); (10) "Communication in Infancy: Mutual Regulation of Affect and Attention" (Vasudevi Reddy, Dale Hay, Lynne Murray, and Colwyn Trevarthen); (11) "Psychoanalysis and Infancy" (R. Peter Hobson); (12) "Referential Communication: Making Sense of the Social and Physical Worlds" (David Messer); and (13) "Language and Its Pathology" (Margaret Harris). Section introductions point out similarities and contrasts between arguments developed by different authors. Each chapter contains references. (KB)
