Motor Control Theory 1

Question 1

Dynamical systems best addresses

Answer 1

why walking changes to running - abrupt change
Developmental changes in motor skills
Cyclical mvmnts, especially biologically based ones

Question 2

Central representation best addresses

Answer 2

how a pianist executes precise movement sequences

Learned coordination patterns (gymnastics, tennis serve, free throw)

Question 3

Clinical implication - specificity of practice - Define it

Answer 3

The best learning experiences are those that approximate most closely to the movement components and environmental conditions of the target skill and target context

Question 4

Clinical implication - specificity of practice - varied practice

Answer 4

Same task, different variations

Changing a variable, but keeping same task

Question 5

Generalized Motor Program/Schema Theory - central representation or emergent?

Answer 5

Central representation (motor program)

Question 6

The generalized motor program is described by

Answer 6

a fundamental pattern
Defined by invariant features (sequence, relative timing, relative force) - these features don’t change from performance to performance
Mvmnt specific patterns are added then to meet specific demand of task (speed, force)

Question 7

DOF - GMP

Answer 7

Executive control via motor programs

Question 8

What builds motor programs with GMP

Answer 8

Varied practice

Question 9

Dynamical systems AKA pattern theory or Systems theory - Central represenation or emergent?

Answer 9

Emergent - no central representation

Question 10

Describe Dynamical Systems - Bx changes

Answer 10

Bx changes overtime do not follow a linear progression - they make sudden abrupt changes
Moving from stable state - phase transition and then back to a stable state
Stable state - attractor state
Walking to running - ex

Question 11

Dynamical systems - emphasis on

Answer 11

the interaction of the performer and the environment

Mover - Task - Environment
