Lecture 24 - Visual Feedback to control Motor Learning

Question 1

Does learning cause relatively permanent gains in performance?

Answer 1

Yes

Question 2

What are 3 factors that can affect performance?

Answer 2

1. physcial fatigue
2. arousal (inattention/central fatigue)
3. Motivation

Question 3

What task do we use to measure motor learning?

Answer 3

Pursuit Rotor tracking task

Question 4

What is a performance curve?

Answer 4

A graph of performance across trials (often report avergae performance across a number of trials and people)

Question 5

What is the law of practice?

Answer 5

Performance improves rapidly at first, but more gradually later on (ie., diminshing returns). Performance curves are relatively well described by power or exponetional processes

Question 6

Pursuit rotor tarcking task

What are two observations made about the learning process?

Answer 6

1. intial erros are smaller when participants perform the same task on Day 2.
2. rate of re-learning the task is faster when participants perform the task on day 2

Question 7

Do group avergaes of performance curves tell us about individual learning?

Answer 7

No, performance curves often mask individual differences in motor performance and learning

Question 8

Motor learning

T/F: more the data is averaged the less informative it is about individual data points.

Answer 8

True

Question 9

What needs to be relatively permenant to be considered motor learning?

Answer 9

Imporvements in performance

Question 10

Does something like an alignment aid help you learn better?

Answer 10

No, performance may be better, but you won’t see permenant changes and so you can’t consider it motor learning. These change sare also specific to specific practice conditions so it is not motor learning.

Question 11

What does motor learning refer too?

Answer 11

skill aquisition

Question 12

What is motor adaptation?

Answer 12

process of modifying an existing skill for different conditions, equipment etc.
