Dynamical systems theory

dynamical systems theory propsed
peter kugler, scott kelso and michael turvey
proposed dynamical systems theory in 1980s
Dynamical systems theory
many systems work together to influence human movement task
ex of systems
nerves hormones, muscles, skeleton, levers
Dynamical systems theory (individual)
our body (the individual), the environment, and our tasks are constantly changing and interacting
"softly assembled"
Dynamical systems theory (number of systems)
Near infinite number of possible combinations and resulting movements
what combinations do we need to walk? skip?
the combinations that you need are the brain to tell my legs and my body to stand upright, muscles in my legs core and back, coordination to be able to skip correctly.
T or F: system is constantly
searching for stability
disturbance or change of motion, course, arrangement or state
attractor states
ruts on a graph. more attractive the state is the deeper the well.
attractor states can only be reaches as a function of all 3 constraints
control parameters
Influence the characteristics of the behavior
stability, control, altered
when the behavior loses _____________, the ______________ parameter is ___________ and a new behavior emerges
rate limiters
factor or system that has the most control over development at a given point in time.
individual constraints of system that restrains or delays the emergence of a skill
ex of a rate limiter 5 yr old trying to make a basket on a 10 ft goal
child lacks muscular strength to reach the net
"A team is only as good as its weakest player."
An infant with an advanced cognitive neurological capacity to walk but has very weak legs is limited b muscular weakness
DST theory addresses changes in aging
Declines in a system may be a rate controller
recognition of the movement
