Flashcards in Theories Models Frameworks Deck (22):
1

Define Information Processing

How a person receives, stores, integrates, retrieves and uses information

2

Define Postural Control

The ability to control the body's position in space for the duel purpose of stability and orientation

3

What is the outward manifestation of postural control?

Balance- emerges from the interaction of individual with the task and the environment

4

Define Motor Learning

Acquisition and modification of movement
Relatively permeant change to motor performance

5

Factors that influence movement

Environment
Task
Individual

6

Personal factors constraining movement

Cognition:
Perception:integration of sensory impressions into psychologically meaningful information
Action:motor output from CNS to effector systems

7

Task factors constraining movement

Mobility:discrete mov task (beginning and an end) continuous mov tasks (walking) open vs closed
Stability: performed with a nonmoving BOS
Manipulation:inc demand for stability

8

Environmental factors constraining movement

Regulatory: specific aspects of environment that shape mov
Non regulatory: may effect performance but movement does not conform (background noise)

9

Open mov tasks

Requires performers to adapt to constantly changing

10

Closed mov task

Stereotyped task in relatively fixed or predictable environment

11

Theory of motor control

Group of abstract ideas about the control of movement

12

Reflexive Model

Reflexes are building blocks of complex behavior
Peripheral mode of operation

13

Limits to Reflexive model

Does not account for voluntary mov
Does not explain mov in response to sensory stimulus
Single stimulus can result in varying responses depending on context & descending commands

14

Hierarchical theory

Center mode of operation
Higher levels inhibit lower levels (Top Down)
Cortex-voluntary control tone & protective equilibrium reactions
subcortical- excitatory & inhibitory control tone & righting reactions
brain stem- tonic reflexes tone
spinal cord-stretch reflexes for tone & primitive equilibrium reflexes

15

Motor Programming theories

Central And peripheral mode of operation
Storage of complex motor programs
CPG provide neural connections that are stereotyped and hardwired
Reflexes do not drive actions

16

Define Synergy

Kinematic linkage of muscles moving together

17

Limits to Motor Programming theory

CPGs cannot be considered the sole determinant of action
Doesn't account for nervous system dealing with both MS & environmental variables to achieve mov control

18

Systems theory

Function results from multisystem interaction. Int and ext forces
Coordinator structures
Synergies:ensures flexible and stable performance of motor demands
DOF: cont body in multiple DOF

19

Define Motor Control

The ability to regulate and direct mechanisms essential to movement

20

Dynamic systems theory

Control patterns
System of individual parts whose elements collectively behave in an ordered way
Mov emerges as a result of interacting elements w/out commands from nervous system

21

Degree of flexibility

Attractor wells
Deep well: hard to charge the preferred pattern (stable rigid)
Shallow well: unstable pattern and less rigid

22

Ecological Theory

Environment drives and molds activities
Limit: less emphasis on organization & function of nervous system
