While it is often assumed that behavioural development must be based upon both physical law and the biological principles of morphogenesis and selection, forging a link between these disciplines has remained an elusive goal. This book addresses the question of how familiar human functional acts - eating, walking, manipulating objects, smiling, etc. - emerge during infancy due to both intrinsic dynamics and selective processes. The central thesis of the book is that during perceptually guided spontaneous activity, a variety of biodynamic devices for doing different kinds of work are assembled and adapted to specific tasks. Following the introductory chapters, which explore principles from the fields of dynamics and ecological psychology, the author introduces a theory of the development of action systems based upon both self-organisation in complex systems and perceptually guided selective processes. The theory is then examined in the context of development of each of several action systems. The book addresses many long-standing issues in behavioural development, including the apparent disappearance of so-called primitive behaviours, the emergence of new skills, and the role of the caregiver on skill acquisition. The prospects for extending the theory to atypical development and to other domains such as cognition and language are also considered.

Robotic exoskeletons that allow stroke survivors to regain use of their limbs, 3D-printed replacement body parts, and dozens of other innovations still in schematic design are revolutionizing the treatment of debilitating injuries and nervous system disorders. What all these technologies have in common is that they are modeled after engineering strategies found in nature-strategies developed by a vast array of organisms over eons of evolutionary trial and error. Eugene Goldfield lays out many principles of engineering found in the natural world, with a focus on how evolutionary and developmental adaptations, such as sensory organs and spinal cords, function within complex organisms. He shows how the component parts of highly coordinated structures organize themselves into autonomous functional systems. For example, when people walk, spinal cord neurons generate coordinated signals that continuously reorganize patterns of muscle activations during the gait cycle. This self-organizing capacity is just one of many qualities that allow biological systems to be robust, adaptive, anticipatory, and self-repairing. To exploit the full potential of technologies designed to interact seamlessly with human bodies, properties like these must be better understood and harnessed at every level, from molecules to cells to organ systems. Bioinspired Devices brings together insights from a wide range of fields. A member of the Wyss Institute for Biologically Inspired Engineering, Goldfield offers an insider's view of cutting-edge research, and envisions a future in which synthetic and biological devices share energy sources and control, blurring the boundary between nature and medicine.
