Providing Feedback During motor learning Flashcards
Augmented Feedback
-Augmented feedback is an important part of motor learning
Augmented Feedback: Information about a movement outcome. This additional feedback comes from an external source (i.e.,
instructor, video) and augments intrinsic feedback
-Supplements information about performance
Feedback
Feedback: Information about movement patterns or outcomes the nervous system can use to guide future movements
Augmented Feedback Properties and intrustuction
-Feedback provides information to
correct errors
-Feedback can be motivational
-Feedback can focus attention
Feedback can produce dependence
What type of feedback should I provide: Knowledge of results
- Augmented information about
the success (yes or no) or degree of success of an action relative to the goal of the task
-Redundant when is settings of if you scored or not
-No redundant about a subjective/graded outcome
What type of feedback should I provide: Knowledge of performance
Augmented information about movement patterns while performing a motor task
-Specific feedback/information for improvement
How much feedback should I give?
With trials of 50 vs 100% feedback,
Tapered Feedback: Provide frequent
feedback during early learning and
progressively withdraw feedback
as learner becomes skilled at task
- This is best
in terms of 50 vs 100% feedback, both showed similar performance in learning but 50% retained better because didn’t become reliant on feedback
When should I give feedback?: Instantaneous vs delayed feedback
Instantaneous Feedback:
Feedback provided immediately after movement that informs learners about
the trial that was just completed
Delayed Feedback: Feedback provided a short period of time after movement that informs learners about the trial that was just completed
-Instantaneous can make learner dependant of feedback
-Delayed shows better retention of learning
When should I give feedback?: Letting the learner decide when they want feedback
Learner-Determined Group:
Best learning and retention
Learning and retention were highest in the learner-determined feedback group. They also self-selected to use
tapered feedback
When should I give feedback?: The timing of when feedback is provided can impact learning and retention
Terminal KP: Feedback displayed
on computer monitor only after the trial is completed
-best learning
-worst in practise
Concurrent KP: Real-time feedback of
movement pattern displayed on
computer monitor
-mid asf
Guidance KP: Real-time feedback +
physical/haptic guidance
-worst learning
-best in practise

In terms of practise

- Concurrent
- Guidance
In terms of learning
How precise should I be?: Summary feedback
-Feedback provided after a series of trials that informs learners about each of the attempts in the series
Summary feedback can help prevent the learning becoming dependent on feedback
May force learner to focus on proprioception and vision to detect their own errors
May produce more stable movement patterns and strengthen motor programs
-reliable information about what needs to change and how to change it
How precise should I be?: Summary feedback: Average Feedback
-Feedback provided after a series of trials that informs learners about their average performance
Average feedback may help prevent or minimize feedback-dependency
May help instructor to develop better
understanding of what kinds of errors the learner typically makes
- reliable information about what needs to change and how to change it.
