Week 3 - AEP Measurement of learning and performance

Question 1

Measurement of motor performance in clinical rehab is necessary to provide a quantitative basis for?

Answer 1

1. Assessing motor capabilities and limitations
2. determine the source of performance limitations
3. provide evidence that skills are improving from my chosen interventions

Question 2

What are performance characteristics?

Answer 2

1. outcome of executing a motor task
2. directly observable or measurable
3. temporary
4. Fluctuates from variables that do not affect learning

Question 3

What are learning characteristics?

Answer 3

1. not directly observable
2. inferred from performance
3. results from practice
4. relatively permanent change

Question 4

If performance is variable, how can we infer that learning has occurred?

Answer 4

1. persistent improvement
2. increased consistency
3. stability of performance
4. adaptability
5. reduction of attentional demand

Question 5

Your task as a clinician is to?

Answer 5

1. identify the key features of a skill
2. prioritize performance characteristics that will ensure success
3. Measure key performance characteristics that can show mastery

Question 6

What do outcome measures do?

Answer 6

Indicate the result of performing a motor skill.
Ex. Distance walked
Time to complete a task

Question 7

Do outcome measures give info about movements of head, limbs, or body?

Answer 7

No

Question 8

What do production measures do?

Answer 8

measure characteristics of movement that produced the outcome

Question 9

What do production measures provide info for?

Answer 9

muscular activity
Limb interaction before a skill
nervous system function

Question 10

What are biomechanical measures?

Answer 10

displacement
velocity
acceleration
joint angle

Question 11

what are kinetic measures?

Answer 11

Joint torque

Ground reaction forces

Question 12

What are some ways to measure performance production?

Answer 12

EMG
For brain activity:
EEG, PET

Question 13

What do all skilled task performances require?

Answer 13

Task accuracy

Question 14

What can error measurement reveal?

Answer 14

Patterns of change in performance that can be used to customize interventions

Question 15

What is absolute error?

Answer 15

Criterion score - Actual score

Question 16

What is constant error?

Answer 16

• magnitude and direction

Average error over a given # of trials including signs (+/-)

Question 17

What is variable error?

Answer 17

1. consistency of responses, not amount of error.

2. Standard deviation of error around patients average performance.

Question 18

All to left and spread out

Answer 18

Hi absolute error
Low constant error
Hi variable error

Question 19

Dart board

All spread out

Answer 19

Hi absolute error
Hi constant error
Hi variable error

Question 20

Dart board

All together and on the left side.

Answer 20

Hi absolute error
Low constant error
Low variable error

Question 21

Bullseye

Answer 21

Low everything

Question 22

Learning review.

What are we looking for in learning?

Answer 22

1. Persistent improvement
2. increased consistency
3. stability of performance
4. adaptability
5. reduction of attentional demand

Question 23

What does retention measure?

Answer 23

Measures PERSISTENCE of performance improvement

EX. assessment of performance of same skill under same conditions over time.

Question 24

What does retention reflect?

Answer 24

Strength of MOTOR MEMORY representation created during learning process

Question 25

What does retention test graph tell us? (2)

Answer 25

1. target hits INCREASE with each practice in a blocked trial of 10 sessions in ONE DAY
2. Ove a WEEK. Retention will go DOWN on the second day, but go up at the end of the week.

Question 26

What does transfer of learning measure?

Answer 26

The ADAPTABILITY of a skill under different conditions.

Question 27

What info does transfer give us?

Answer 27

extent to which a learner may perform in different situations.
