12. Feedback Flashcards
List the classifications of feedback.
- Intrinsic Feedback
- Extrinsic/Augmented feedback
- Knowledge of Results
- Knowledge of Performance
What is extrinsic/augmented feedback/? Examples?
Info from measured performance outcome that is fed back to the learner by artificial means
-ex) video, coaching
What is intrinsic feedback? Example?
Info performer receives as a natural consequence of their actions
-ex) proprioception
Explain Knowledge of Results. Example?
More about the goal/outcome of the movement
-ex) seeing ball go in goal or wide left
Explain Knowledge of Performance.
More about nature of the movement
-ex) “You let go too soon.”
Is KR or KP more important for skilled learning? Why?
KP b/c this feedback tells about the movement, not just the outcome
What are the functions of feedback? Explain.
- To get efficient & optimal performance
- Motivational, energizing = give plenty, but not too much
- Reinforcing = Law of Effect (positive things happen to increase likelihood of behavior happening again)
- Informational = could be worthless if athlete knows this already (“You suck”)
- Dependency-producing = too much feedback
What is intermittent reinforcement?
- Has to do w/ schedule of feedback
- Not giving reinforcement after every trial
- Give it on an unknown pattern
What is a better alternative to dependency-producing feedback? Goal of this?
- Coach should start w/ a question –> “How did that go for you?”
- Goal = produce self-coached, knowledgable, self-aware athletes
What are the contents of feedback?
- What learner can control
- Motor program variables
What are the aspects of parameter feedback?
- W/in the same program
- Given once pattern is essentially correct & well-learned
- Parameters = duration, direction, amplitude
What are the different kinds of feedback info?
- Direction = early/late, high/low, left/right
- Magnitude = how much
- Precision = more useful @ higher skill level
What are the aspects of prescriptive feedback?
- Assess = watch, observe
- Identify = problem, correction, positive feedback
- Decide = how to address prob & help athlete
- Prescribe = actually doing it
What are some feedback aids?
- Strip-chart paper (EKG, richter scale)
- Film
- Video
- Computer readouts
- Simulators, virtual reality
What is Thorndike’s Law of Effect?
- Too much feedback to learners can cause overload, desensitization, not knowing what to process & when
- Punishment might decrease likelihood of a behavior occuring
