Augmented Feedback_PL Flashcards
Term: Information available about one’s movement that is available through one’s one sensory channels
Inherent (Intrinsic) Feedback
Term: This is information provided about the movement in addition to inherent feedback. Can be verbalized/lends itself to being verbalized
Augmented (extrinsic) feedback
Term: Information about movement outcome related to the environmental goal. Not feedback about the quality of the movement itself
Knowledge of Results (KR) [Outcome]
Term: provides information about the movement pattern after a movement was performed. Tends to be more descriptive
Knowledge of performance (KP) [Quality]
Term: the time b/t the time the movement ends and KR is provided
KR Delay
Term: The time b/t whe KR is provided until the beginning of the next movement
Post-KR Delay
Term: Augmented feedback provided the instant the performance is complete. (As soon as your client completes a task, you provide feedback
Instantaneous feedback
Describe the types of KR Delay that are not good for learning
Extremely short KR Delay
Extremely long KR Delay
Term: Augmented feedback provided during the movement. Typically visual
Concurrent feedback
Describe why concurrent feedback is not good for learning
- The performer attends more to the feedback than the task
- The learner may become dependent on the feedback
Term: encouraging the learner to estimate or evaluate their own error during the KR Dleay
Error estimation
**Can improve learning (only helpful if accompanied by KR)
Describe the effect of short Post-KR delay
Can interfere with learning. The learner needs time to plan and generate a new movement based on the KR
Describe the importance of the Precision of KR
Precise KR is better than qualitative KR for learning
However, too precise KR is not helpful
Term: the number of trials of practice that are followed by KR
absolute frequency
Term: the percentage of trials that are followed by KR
relative frequency
Describe the issue with KR after every trial
KR after every trial causes increased variability of performance b/c the learner has to adjust his/her performance to each trial and they again may become dependent on the feedback
Thus reduced frequency KR is better for learning
Described faded schedule KR feedback
There type of feedback indicated more feedback more frequently early on in the practice and less feedback less often towards the end
This type of feedback appears to be better than feedback after every other trial
Describe KR Bandwidth
The bandwidth is the range of correctness that is considered acceptable or pasing performance. To promote learning the bandwidth should being wide and narrow over time.
However, if the bandwidth becomes too narrow the task can become too difficult forcing the pt. to try to achieve unattainable perfection
Describe average KR
Feedback is not provided on every trial. Performance is averaged over a pre-determined number of trials and feedback is provided on that average
Describe learner-determined KR
The learned is provided KR only when they ask for it. These method is useful for learning b/c the feedback appears to be more meaningful when it is requested
