Categories of feedback
task-intrinsic feedback
Vision, touch, etc.,
Augmented feedback
Results information feedbackKR knowledge of results
The main feedback is performance results, and sometimes it only tells whether the goal has been achieved.
Performance information feedback KP knowledge of performance
Mainly feedback the movement process and action characteristics
Examples of KR and KP
Add feedback function
- Promote achievement of motor skill goals
- Motivate learners to keep moving towards their goals
Four possible answers...
It is necessary for skill learning
- Task ontology feedback is not available
- Blocked sensory pathways in the body
- Not able to use it due to lack of experience
May not be necessary
- Sensory systems can provide adequate proprioceptive feedback
- The environment has observable external information references, etc.
- Able to see at a glance, good demonstration (observation learning)
Can enhance skill learning
- For simple skills (the goal is easy to achieve), you can learn it faster and reach a higher level faster.
- Complex skills require mastery of multi-body coordination and require coaching to enhance
Can inhibit or slow down learning
- Dependence arises from practicing learning
- learner is given erroneous feedback erroneous feedback
- learner is given concurrent feedback Synchronous feedback creates dependence and cannot proceed without feedback
- Lerner is given too frequent augmented feedback too frequent feedback
5 topics for additional feedback
- Provide it when you're wrong or when you're right?
- Is it better to give it to KP or KR?
- Quantitative or qualitative information?
- Performance bandwidth: the size of the error and the extent of the error for feedback
- Wrong additional feedback
Provide it when you're wrong or when you're right?
- Error messages serve as feedback. Feedback when errors are made is more effective for improving skills.
- Correct information is used to motivate better
Is it better to give it to KP or KR?
- Industry insiders prefer KP
- There is no absolute answer to which one is better
KR is good in these situations:
Confirm self-assessment and understand your own situation
Required when there is no task body feedback
excitation
Encourage active learning
Ensure external attention and focus on athletic performance
KP is good in these situations:
Skills require specific actions
Complex multi-limb coordination
Goals include movement, motivation, and muscle activity needs
When KR is redundant
Quantitative or qualitative information?
- Initially, more reliance was placed on qualitative information (concepts)
- Later, more reliance will be placed on quantitative information to adjust actions (specific)
Performance bandwidth: the size of the error and the extent of the error for feedback
- No feedback is provided within the performance bandwidth
Wrong additional feedback
Is redundant feedback ignored?
Ignore residual feedback and performance is not affected
Error feedback can impact performance if not ignored
Beginners can use it in the early stages, whether it is right or wrong.
Type of KP
Verbel KP :
Selecting the skill component for KP
Decriptive and Prescriptive KP
Descriptive KP: describe the action results or goals
Guiding KP: Provide guidance on the process and details to achieve the goal
Manual Guidance as AF action guidance
Assist movement to the correct position through hand guidance
For example, a fitness instructor guides students to exert force correctly by touching muscle parts.
Video Recording as AF video recording
Obtain feedback on exercise processes by reviewing videos
Beginners need an instructor to explain, advanced levels can understand on their own
Movement Kinetics and Kinematics as AFKinetics and Kinematics
By explaining relevant theoretical knowledge
Allow students to acquire coordination patterns faster
BIoffeedback as AFbiofeedback
Muscle strength, ECG, respiration, electromechanical, motion capture...etc. testing methods (EMG)
and can be used to change actions
such as micro electrical stimulation
The issue of timing of additional feedback (when to give it)
Synchronization and terminal, KR delay and post-KR interval, frequency issues
Sync and terminal AF
Give feedback during the process and give feedback after the end
KR delay and post-KR interval
