HKIN 215 Lecture Notes - Lecture 5: Motor Program, Dynamical Systems Theory, Reaction Coordinate
Document Summary
Emphasize central nervous system or interaction between environment and individual. Two theories of motor control: motor program based theory, early theories believed that each movement has separate motor program stored in memory. Definition of a motor program: keele (1968, schmidt (1975, general framework for class of action, having a common but unique set of features. Schema theory: accounts for discrete motor skills (short in duration, kicking, throwing, jumping, explains coordination and control of motor skills, two control components, gmp, motor response schema. Evidence for gmps: walking vs. running, studied relative time by increasing treadmill speed, different gmps components are different in terms of relative time. Nonlinear dynamics: changes in human motor control are not always a linear behaviour, ex: boiling water. In-phase: limbs at equivalent points in movement cycle w/ respect to each other: anti-phase: opposite point of movements. Transition: change from one state to another, if system is perturbed (environment changed)
