open and closed motor control, SCHEMA and WHITING and WELFORDS models Flashcards
what are the 3 theories of how motor programmes are run and conrtolled?
- closed loop control theory
- open loop control theory
- Schema theory
what is the closed loop control theory?
focuses on intrinsic feedback, errors are detected and **corrections are made during performance. **
E.g. balance beam and swimming.
what is the open loop control theory?
all the information sent as a single message for the movement. Not reliant on feedback.
E.g. penalty kick, basket ball set shot
whats schema’s theory?
A GENERALISED MOTOR PROGRAMME WHICH CAN BE ADAPTED.
challenges open and closed loop motor control theories.
**Suggests the motor programmes are clustered together and are interchangable in responce to the situation making them adaptable. **
* so it is essential that practice is varied as much as possible to strengthen schemas
* a general set of rules
EXAMPLES:
- punching schema
- kicking schema
- throwing schema
what are the 2 other information processing models besides the basic information processing model?
Whitings model and Welfords model
whats Whitings model split up into?
whitings split information processing into 3 stages:
* PERCEPTUAL MECHANISM (input)
* TRANSLATORY MECHANISM (decision making)
* EFFECTOR MECHANISM (output)
- and feedback
whats Welfords model split up into?
split into the stages :
* perception (input)
* translation (decision making)
* effector (output)
* feedback
explanation on input / perception mechanism (whiting) / perception
- sense organs (vision, audition and propriocepters) in Whitings this is also called **receptor systems **
- DCR process
- STSS
- SA
explanation on translator mechanism (whiting) / translation / decision making
- STM
- LTM
- STM - LTM relationship
explanation on output / effector / effector mechanism (whiting)
- muscles and nerves
- motor programmes
explain feedback
types of feedback, positive, negative, terminal, concurrent, Knowledge of performance, knowledge of results, intrinsic, extrinsic.
-MRI , motivate reinforce and inform.
how can the coach improve the information processing model?
IMPROVEsensory input and decision making when learning a skill the coach could:
-use a bigger ball **
- reduce cues so the learner is not overloaded
-ensure skills are well learned to free up spare attention capacity **
-reduce anxiety
**IMPROVE MEMORY BY:
-providing lots of practice **
-use **phrases and saying that will help performers to remember key points E.g. BEEF for basket ball free throw (balance, eyes , elbow, follow through)
-make sessions more exciting
IMPROVE DECISION MAKING BY:
-varying practice so performers experience a range of difficult situations** WHICH builds up LTM improving decision making
IMPROVE REACTION TIME and ANTICIPATION BY :
-giving performers important cues to watch for
- practice
IMPROVE FEEDBACK BY:
-use informational/technical feedback wisely so the performer does not become dependant on it
