Lecture 11: Augmented Feedback Flashcards
What does Feedback mean?
- A persons performance of a task
What does augmented mean
- Having been made in greater size or value
What are the two types of Performance-Related Information (Feedback)
- Task-intrinsic feedback
- Augmented feedback
Task-intrinsic feedback
- Sensory information that is naturally available when performing a skill.
Augmented Feedback
- Describe information about a performance that supplements sensory feedback.
- Performance related info that is added to task-intrinsic feedback
- Typically comes form an external source.
What are the two types of Augmented Feedback?
- Knowledge of Results (KR)
- Knowledge of Performance (KP)
Knowledge of Results (KR)
- Externally presented info about outcome of an attempt to perform a skill
- Yes or no feedback
Knowledge of Performance (KP)
Externally presented info about movement characteristics that led to the performance outcome.
Example of KP and KR (Golf Instructor)
- KR: Your shot went into the right rough
- KP: You began to downswing before you finished your backswing.
What are the two roles of Augmented Feedback in skill acquisition?
- Provides info that facilitates achievement of the goal of the skill.
- Success determines if skill is being done properly
- Learner learns skill faster when there is no external feedback - Motivates the learner to continue striving toward a goal
- Helps make decision to continue.
- Motivation
Five Issues Related to Augmented Feedback Content?
- Information about errors vs. correct aspects of performance.
- KR vs. KP
- Qualitative vs. Quantitative Information
- Augmented feedback based on error size
- Erroneous augmented feedback
Information about errors vs correct aspects of performance
- Information on errors useful for learning.
KR vs. KP
- Both are effective, but KP better than KR based on the skill performed.
Qualitative vs Quantitative info
- Research suggests qualitative is preferred early, and quantitative is preferred later.
Augmented feedback based on error size
- Performance bandwidths
Erroneous augmented feedback
- Hinders learning; no feedback is better than wrong feedback
Concurrent Augmented feedback
- Augmented feedback provided while a person is performing a skill.
What can concurrent augmented feedback do?
- Have a negative effect on learning- improvement in practice but not during retention.
- Enhance learning- When task intrinsic feedback is low.
Note: Subtle variations in the way concurrent feedback is provided can influence whether learners become dependent on feedback.
Bio-feedback
In addition to the task intrinsic feedback or when there is a deficiency in task intrinsic feedback
1. EMG systems
2. Heartbeat monitor
note: Helpful in rehab and sport performance and enhancement.
