what are 4 advantages of the closed-loop system?

1) new skills
2) activities requiring precision and accuracy
3) allows adjustment according to the situation
4) adds versatility to movements

32

what are 2 disadvantages of the closed-loop system?

1) rapid, discrete actions do not properly fall under closed-loop control
2) demands attention and time
-feedback must pass through the processing stage

33

open-loop control

describes control of automatic actions

34

when are movements structured in open-loop system?

movements may be structured in advance, enabling them to run off automatically when initiated

35

what are the 2 main components of the open-loop system?

1) the executive
2) the effector

36

executive

-chooses motor program
-relays instruction

37

effector

-carries out specific instructions automatically

38

what are 3 advantages of the open-loop system?

1) fast and forceful movements can be produced without extensive conscious control
2) attention can be diverted to other responses
3) does not demand as much time because there is no feedback

39

what are 2 disadvantages of the open-loop system?

1) not as effective in unstable and less predictable situations
- movements may not be determined effectively in advance
2) not effective in precise and complex actions

40

what are the 6 factors affecting information processing?

1) arousal and psychological readiness
2) capacity to concentrate
3) ability to anticipate
4) reaction time
5) sensory receptors relay
6) sensory input quality
