MC Final: Augmented Feedback Flashcards
What is intrinsic feedback?
information about motor performance naturally present in the environment
ex: proprioceptive, sensory receptors
What is augmented or extrinsic feedback?
information provided to the learner that is typically not available in the natural environment
ex: judge scores, test results
With augmented feedback what are the two basic types?
- knowledge of performance
2. knowledge of results
What is KP?
information about patterns of action
ex: how did your leg move while kicking the ball
What is KR?
information about movement outcome
Can be intrinsic and extrinsic be either KP or KR?
Yes, main difference is whether it is naturally present in environment or not
What are different dimensions of augmented feedback?
- concurrent vs terminal (during and after performance)
- immediate vs delayed ( right after trial or wait a few trials)
- verbal vs non- verbal
- summary (accumulated) vs per-trial (distinct)
- KR vs KP
Does immediate KR lead to learning?
studies show better performance but not learning
How can a therapist enhance KP?
visual observation in mirror and palpation or with equipment like videos or EMG/ force plates
What is one downfall of videos?
sometimes there is too much information on a video and it can hinder pts learning
What should PT do to utilize videos best for learning?
key pts on what parts on important
ex: “ look at just your knees”
What are kinematics?
measuring motion without regard to the forces that produced the motion
What is selective attention?
example is the gorilla video
So which is better KR or KP?
KR because it directs attention to the impact of the movements on the environment
What is biofeedback?
feedback given about the movement features not perceived directly
ex: blood pressure and muscle activity
What are adverse effects of biofeedback?
can be beneficial for skill acquisition but not for learning
What is important to remember about knowledge of performance?
selecting the key information to give to the patient is critical, this information also changes from task to task
What is kinetics?
forces and torques involved in movement
What is the most effective type of KR?
precise and quantitative more than qualitative
What are two different kinds of feedback?
- absolute frequency- number of trials
2. relative frequency- percentage of trials
Which is better for learning?
absolute frequency, however it must be reduced number of frequency because this will engage subject in learning during acquisition
What is better for learning summary or immediate feedback?
summary
What is self regulated KR?
when pt can determine intrinsically when they need feedback can be very effective for learning
What is rationale behind why self regulated KR is good?
decision to receive feedback engages learner in process, subject requesting feedback after good trials could serve as positive motivation
How can augmented feedback enhance learning?
- informational- what to do next?, objective and reliable source of knowledge rather than noisy sensory info
- motivational- has energizing effect
- Associational- mapping connections between internal commands and movement outcomes
How can augmented feedback degrade learning?
blocks other processing activities, could induce maladaptive corrections “too much corrections” or unnecessary
