Motor Learning Chapter 5 Flashcards
the Components of open loop control are:
- executive
- effector no comparator or use of feedback
What are some of the characteristics of open loop control?
- advanced instructions= movement pre-planned
- Advanced sequencing = arranged at the CNS
- Not direct conscious control
- can not be modified once motor program is sent
what is a disadvantage of open loop control?
it’s not as accurate
What is an advantage of open loop control
one can act more quickly
what term can be used instead of “muscle memory?’
Motor Program
____ is a set of motor commands that are pre-structured at executive level, that defines the essential details of a skilled action
motor program
with practice, motor programs are capable of:
controlling longer sequences of actions and more elaborate movements
What specifications does the MP process need?
- Particular muscles used to produce the action
- order in which these muscle would be activated
- relative forces of the various muscle contractions
- relative time. sequencing of contractions
- duration of respective contractions
What are the major roles of motor programming
•Define and issue commands to the muscles needed to produce the goal movement
• Coordinate the many degrees of freedom needed
to produce an effective and efficient action.
-specify and initiate any
preliminary adjustments to support upcoming action.
According to reaction time and movement complexity: adding additional elements to the movement increases ______
reaction time
According to reaction time and movement complexity: more limbs added to the elements increases ______
reaction time
According to reaction time and movement complexity: When we have an increase in movement duration; it also increases reaction time
reaction time
Demonstrates that _______ information from the moving limb is not essential for movement production
proprioceptive
deafferentation studies prove:
(we can act without stimulus)
evidence for motor programs include
- reaction time and movement complexity
- deafferentation studies
- Inhibiting actions
- EMG electromyography studies
