Term
| Reflex theory of motor control |
|
Definition
Stimulus ---> response
ex: see fire ---> run away |
|
|
Term
| Limitations of reflex theory |
|
Definition
-single stimulus results in varying responses
-reflex cannot be considered basic unit of behavior
-Does not explain
-movement w/out stimulous
-fast movement
-novel movement |
|
|
Term
| Hierarchical motor theory |
|
Definition
-Higher levels of nervous system can act on lower levels
-Reflexes are important
- |
|
|
Term
| Limitations of hierarchical motor theory |
|
Definition
-Stepping on a tack - bottom up control
-cannot explain reflex behavior in certain situations in normal adults |
|
|
Term
|
Definition
-Central motor program
Sensory input (not essential)
but important in modulating action
-Central Pattern Generators
spinally mediated motor program
-Movement w/out brain interpretation of sensory input |
|
|
Term
| Limitations of Motor Program Theory |
|
Definition
-Central Pattern Generators cannot replace the importance of sensory input in control of movement
-CPG cannot be sole determinate of action |
|
|
Term
| Systems theory of motor control |
|
Definition
- body is subject to external and internal forces
-Body is a mechanical system with many degrees of freedom |
|
|
Term
|
Definition
-Control parameter
-self organization
-attractor states
-De-emphysis on CNS control |
|
|
Term
|
Definition
-Movement results form interaction of physical and neural components
-Takes into account: CNS, mechanical aspects of body, and environment |
|
|
Term
| Ecological theory of motor control |
|
Definition
-motor control evolved so animals could cope with environment
-Sensation and perception important |
