MC Final: Augmented Feedback

Question 1

What is intrinsic feedback?

Answer 1

information about motor performance naturally present in the environment

ex: proprioceptive, sensory receptors

Question 2

What is augmented or extrinsic feedback?

Answer 2

information provided to the learner that is typically not available in the natural environment

ex: judge scores, test results

Question 3

With augmented feedback what are the two basic types?

Answer 3

1. knowledge of performance

2. knowledge of results

Question 4

What is KP?

Answer 4

information about patterns of action

ex: how did your leg move while kicking the ball

Question 5

What is KR?

Answer 5

information about movement outcome

Question 6

Can be intrinsic and extrinsic be either KP or KR?

Answer 6

Yes, main difference is whether it is naturally present in environment or not

Question 7

What are different dimensions of augmented feedback?

Answer 7

1. concurrent vs terminal (during and after performance)
2. immediate vs delayed ( right after trial or wait a few trials)
3. verbal vs non- verbal
4. summary (accumulated) vs per-trial (distinct)
5. KR vs KP

Question 8

Does immediate KR lead to learning?

Answer 8

studies show better performance but not learning

Question 9

How can a therapist enhance KP?

Answer 9

visual observation in mirror and palpation or with equipment like videos or EMG/ force plates

Question 10

What is one downfall of videos?

Answer 10

sometimes there is too much information on a video and it can hinder pts learning

Question 11

What should PT do to utilize videos best for learning?

Answer 11

key pts on what parts on important

ex: “ look at just your knees”

Question 12

What are kinematics?

Answer 12

measuring motion without regard to the forces that produced the motion

Question 13

What is selective attention?

Answer 13

example is the gorilla video

Question 14

So which is better KR or KP?

Answer 14

KR because it directs attention to the impact of the movements on the environment

Question 15

What is biofeedback?

Answer 15

feedback given about the movement features not perceived directly

ex: blood pressure and muscle activity

Question 16

What are adverse effects of biofeedback?

Answer 16

can be beneficial for skill acquisition but not for learning

Question 17

What is important to remember about knowledge of performance?

Answer 17

selecting the key information to give to the patient is critical, this information also changes from task to task

Question 18

What is kinetics?

Answer 18

forces and torques involved in movement

Question 19

What is the most effective type of KR?

Answer 19

precise and quantitative more than qualitative

Question 20

What are two different kinds of feedback?

Answer 20

1. absolute frequency- number of trials

2. relative frequency- percentage of trials

Question 21

Which is better for learning?

Answer 21

absolute frequency, however it must be reduced number of frequency because this will engage subject in learning during acquisition

Question 22

What is better for learning summary or immediate feedback?

Answer 22

summary

Question 23

What is self regulated KR?

Answer 23

when pt can determine intrinsically when they need feedback can be very effective for learning

Question 24

What is rationale behind why self regulated KR is good?

Answer 24

decision to receive feedback engages learner in process, subject requesting feedback after good trials could serve as positive motivation

Question 25

How can augmented feedback enhance learning?

Answer 25

1. informational- what to do next?, objective and reliable source of knowledge rather than noisy sensory info
2. motivational- has energizing effect
3. Associational- mapping connections between internal commands and movement outcomes

Question 26

How can augmented feedback degrade learning?

Answer 26

blocks other processing activities, could induce maladaptive corrections “too much corrections” or unnecessary
