Feedback Flashcards
Two types of performance related feedback
Task-intrinsic feedback
Augmented feedback (extrinsic)
Task intrinsic feedback
Naturally occurring feedback-sensory-perceptual info that is natural part of performing skill
ex) see target, feel ball, hear swoosh, proprioception
Augmented feedback
Performance related info adding to or enhancing task intrinsic feedback
Ex) verbal, watching videos of oneself
Two forms of augmented feedback
Knowledge of results
Knowledge of performance
Knowledge of results
Additional or enhanced info about the movement outcome or achievement of movement goal
Example of movement outcome
Shot was 5cm too long, knee was flexed 10 degrees too much
Example of achievement of movement goal
Shot missed, shot made
Knowledge of performance
Additional or enhanced info about the movement characteristics leading to the performance outcome
Ex) didn’t bring club back far enough
Examples of task intrinsic senses
Visual, auditory, proprioceptive, tactile
How does augmented feedback enhance motor learning
- Facilitates achievement of action goal
- Motivates learner to continue with learning
Augmented feedback is essential if:
- Skill performance does not produce critical sensory feedback
- Injury/disease has removed sensory info
- Performer cannot use critical task-intrinsic feedback appropriately (young people)
When is augmented feedback not essential
Performance provides sufficient task-intrinsic feedback (enough sensory info)
- sometimes augmented is redundant and does not enhance learning
Augmented feedback can impair motor learning when:
- Task intrinsic feedback is minimal or difficult to interpret
- Augmented feedback is erroneous/incorrect
- Concurrent augmented feedback
- Augmented feedback is provided too frequently
What happens when task intrinsic feedback is minimal or difficult to interpret and augmented is used
Learner ends up substituting augmented for task-intrinsic
What happens when augmented feedback is incorrrect
Learners (especially early) will use augmented whether correct or not
Two types of timing of augmented feedback
Terminal vs concurrent
