This is the 33rd volume in the Minnesota Symposium on Child Psychology held in October 2002. The symposium was held to honor the scientific and mentoring contributions of Anne Danielson Pick and Herbert L. Pick, Jr.--two longtime and beloved professors of the Institute of Child Development. It focused on "Action as an Organizer of Learning and Development" and integrated the best and most innovative research on the role of action in perceiving and understanding. Taken together, the book captures the intellectual excitement that characterized the 33rd symposium and appeals to developmental psychologists, particularly those interested in perceptual development.

Research into the development of sensory structures in the brains of blind or visually-impaired individuals has opened a window into important ways in which the mind works. In these individuals, the part of the brain that is usually devoted to processing visual information is given over to increased processing of the touch and hearing sense. This demonstration of brain plasticity is of great importance to cognitive neuroscientists and cognitive psychologists, and has real implications for rehabilitation and education specialists who work with the visually impaired. This is an interdisciplinary book, featuring chapters from cognitive and developmental psychologists, neurologists and neuroscientists, and rehabilitation specialists and educators. All of these groups do research in this area but generally do not collaborate with one another. This book is an attempt to bring together the disparate threads of research into a single volume, appropriate for all three markets.
