This book appraises the main theoretical ideas currently characteristic of the motor behavior field, bringing together contributions from many internationally known scientists who are doing this important research. Much of the work presented utilizes new recording techniques aimed at obtaining a complete kinematic account of how movement is executed. The motor behavior field as described in this volume is dominated by approaches which emphasize the dynamics and kinematics of movement. There is also an emphasis on new electrophysiological measures. The volume is organized into several sections based on specific themes. Chapters contained in each section discuss many currently debated questions in the field concerning motor mechanisms and their implementation for motor control.
