Motor Learning; intro and core theories

Question 1

Measuring performance

Answer 1

Intuitive approach may have it that performance improvement represents learning

Performance measure (y-axis)
Practice variable (x-axis)
performance x practice

Question 2

Learning Trends

Answer 2

Linear- Improvement level directly coincides with stages of practice

Ogive (s-shaped)- slow start, rapid improvement, eventually reaches a plateau

Positively accelerated- exponentially improves with stages of practice

Negatively accelerated- rapid improvement that exponentially slows to a plateau

Question 3

Error Measures

Answer 3

Performance is usually quantified by error - the difference between performance. and select criteria (eg perfect performance)

Question 4

Error measures cont

Answer 4

total error=√mean error² + variable error²

source of error;
-systematic (mean)
-random (variability)

Question 5

Learning characteristics

Answer 5

Importance to also recognise that evidence of “learning” uniquely involoves:

-relatively permanent changes
-no influence of extraneous variables

Persistence
Adaptability
Retention
Transfer
