2.10 Feedback

Question 1

two types of feedback

Answer 1

• extrinsic

- intrinsic

Question 2

extrinsic feedback

Answer 2

• environment (outcome)

- terminality of activity (end)

Question 3

terminal feedback

Answer 3

knowledge of results » outcome

Question 4

timing of terminal feedback

Answer 4

• immediately
• every trial
• varied feedback
• summed
• faded

Question 5

KR: immediate

Answer 5

• cognitive and associative phase
• shouldn’t do it right after because they haven’t had any intrinsic analysis
• wait 3 seconds

Question 6

KR: problem with performing after every trial

Answer 6

• might become desensitized to feedback
• learn quicker, but could become dependent on feedback
• poor retention

Question 7

benefits to KR after every trial

Answer 7

performs better more quickly

Question 8

KR: varied feedback (pro and con)

Answer 8

• takes longer to learn than every trial

- better retention because more independent

Question 9

KR: summed

Answer 9

Wait till the end to give a summated amount of feedback after treatments all at once

Question 10

KR: faded

Answer 10

• May start out with a lot of feedback (summed), but gradually fade over time
• most patients will receive more at the beginning less at the end
• probably better than summed

Question 11

terminal feedback and patient understanding

Answer 11

• Need to keep it simple so they can understand
• find something that works for them
• Don’t bombard with feedback items- can’t fix all the holes at once

Question 12

problems with intrinsic feedback and confidence

Answer 12

• not enough
• too much
• depression
• brain injury
• etc

Question 13

What are the practice conditions?

Answer 13

• massed
• distributed
• constant
• variable
• blocked
• random
• whole
• part

Question 14

practice conditions: massed

Answer 14

practice time (w/in a session) ≥ rest

Question 15

problem with massed practice?

Answer 15

• puts at risk for fatigue which leads to higher risk of injury
• bad form: if in associative phase, will imprint bad habits on the final phase

Question 16

practice conditions: distributed

Answer 16

rest ≥ practice time

Question 17

practice conditions: constant

Answer 17

• same treatment conditions every time

- i.e. sit to stand: same chair, same height, same everything

Question 18

constant practice: pro/con

Answer 18

• learn quickly in that scenario

- doesn’t translate to other conditions

Question 19

practice conditions: variable

Answer 19

• different treatment conditions
• i.e. sit to stand: taking a task and changing aspects of it
• takes longer to learn, but improves under a variety of conditions

Question 20

practice conditions: blocked

Answer 20

• looking at trx time, doing individual treatments for a certain amount of time and moving on to the next one
• learn faster
• could get bored easier

Question 21

practice conditions: random

Answer 21

• use closer to d/c, patient is better
• one activity to another and another
• mimics real life more

Question 22

practice conditions: whole

Answer 22

• do the entire activity

- typically start with whole at least once to see what will happen and break it down as needed

Question 23

practice conditions: part

Answer 23

• do parts of the activity
• simple things have to be practiced a lot
• reverse order

Question 24

reverse order and standing

Answer 24

• start at standing and mini squat, come back up

- if eccentrics get strong, concentrics should get easier

Question 25

contextual interference

Answer 25

- spillover into another task - by learning one thing, I've already learned parts of something else - something that doesn't look like it will help something else actually does

Question 26

What is involved with mental practice?

Answer 26

guided imagery

Question 27

guided imagery

Answer 27

- self or therapist guided - thinking about each step in their mind before doing it - may need a lot of coaching at first, but intrinsic feedback will improve

Question 28

benefit to guided imagery

Answer 28

pt will be able to apply and critique on their own

Question 29

When is guided practice commonly used?

Answer 29

patients have to rest, can do this during rest time

Question 30

Why is it so important to remove guidance over time?

Answer 30

if we don't start removing it ourselves, they will come to depend on it
