REGNRSG 105 Lecture Notes - Information Processing, Embodied Cognition, Mental Rotation
Document Summary
Includes the components of the central and peripheral nervous systems along with the muscles, joints and bones that enable movement. Woodworth (1899): two-component process of motor control. Initiates movement and plans in advance the stat of the the movement. Vision is key to controlling the accuracy of the final endpoint. Bernstein (1967): to plan a movement we must overcome the degrees of position freedom problem. The number of ways in which a joint can move. There are multiple possibilities on how to exercise a movement. Difficult task for motor planning system to plan what body parts will move with what motion. Emphasizes how the problem of control can be simplified by taking into account muscle properties. Muscles act like springs and exert different forces depending on how much they are stretched. Any stable posture requires the setting of various control parameters for muscle activation.
