2.10 Feedback Flashcards
two types of feedback
- extrinsic
- intrinsic
extrinsic feedback
- environment (outcome)
- terminality of activity (end)
terminal feedback
knowledge of results » outcome
timing of terminal feedback
- immediately
- every trial
- varied feedback
- summed
- faded
KR: immediate
- cognitive and associative phase
- shouldn’t do it right after because they haven’t had any intrinsic analysis
- wait 3 seconds
KR: problem with performing after every trial
- might become desensitized to feedback
- learn quicker, but could become dependent on feedback
- poor retention
benefits to KR after every trial
performs better more quickly
KR: varied feedback (pro and con)
- takes longer to learn than every trial
- better retention because more independent
KR: summed
Wait till the end to give a summated amount of feedback after treatments all at once
KR: faded
- 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
terminal feedback and patient understanding
- 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
problems with intrinsic feedback and confidence
- not enough
- too much
- depression
- brain injury
- etc
What are the practice conditions?
- massed
- distributed
- constant
- variable
- blocked
- random
- whole
- part
practice conditions: massed
practice time (w/in a session) ≥ rest
problem with massed practice?
- 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
practice conditions: distributed
rest ≥ practice time
practice conditions: constant
- same treatment conditions every time
- i.e. sit to stand: same chair, same height, same everything
constant practice: pro/con
- learn quickly in that scenario
- doesn’t translate to other conditions
practice conditions: variable
- 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
practice conditions: blocked
- 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
practice conditions: random
- use closer to d/c, patient is better
- one activity to another and another
- mimics real life more
practice conditions: whole
- do the entire activity
- typically start with whole at least once to see what will happen and break it down as needed
practice conditions: part
- do parts of the activity
- simple things have to be practiced a lot
- reverse order
reverse order and standing
- start at standing and mini squat, come back up
- if eccentrics get strong, concentrics should get easier
contextual interference
- 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
What is involved with mental practice?
guided imagery
guided imagery
- 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
benefit to guided imagery
pt will be able to apply and critique on their own
When is guided practice commonly used?
patients have to rest, can do this during rest time
Why is it so important to remove guidance over time?
if we don’t start removing it ourselves, they will come to depend on it
