Nicholai Aleksandrovich Bernstein is considered by many to be the founder of many contemporary fields of science such as biomechanics, motor control, and physiology of activity. Divided into two parts, this volume's first section is a translation of the Russian book On Dexterity and Its Development. It presents, in a very reader-friendly style, Bernstein's major ideas related to the development and control of voluntary movements in general, and to the notion of dexterity, in particular. The second section provides both an historical and a contemporary perspective on Bernstein's ideas.
