L17A: Augmented Feedback Flashcards
performance, learning
c) To increase variability
What is Inherent FB?
(intrinsic / response-produced sensory)
Feedback (FB)
- Touch (via cutaneous receptors)
-
Proprioception (via Muscle Spindles, GTO’s, some
cutaneous afferents, vestibular apparatus) - Vision
- Audition
What are the types of Augmented FB?
(extrinsic/ not naturally occurring)
Feedback (FB)
- Knowledge of results (KR)
- Knowledge of performance (KP)
What is classified as Augmented feedback?
movement related info provided by extrinsic source
Adds to a performer’s naturally occurring intrinsic feedback to
provide information about the movement or movement outcome
Given by Instructor / external person / video or other device
What are the Four ways that Augmented Feedback functions?
-
MOTIVATIONAL ROLE
… provides a reward function “good job” -
ATTENTION-DIRECTING ROLE
… directs attention (internal/external – or to specific features) -
INFORMATIONAL ROLE
… provides error/accuracy information “too much rotation” -
DEPENDENCY ROLE
…creates dependency/reliance on the information
Guidance hypothesis (acts as crutch, problem when removed)
What is the goal of augmented fb?
What is KR?
Knowledge of Results (KR) is information about an
action’s outcome (in relation to a goal)
- How successful was the action based on intended environmental goal?
- This information helps improve the next response (detect error), then repeat or change (correct)
- Important when learners cannot assess their own success
Example of KR:
What is KP?
Knowledge of Performance (KP) is information about
movement quality/form (kinematics)
- KP does not typically indicate anything about environmental-goal success (different to KR)
- Concerned with the quality of the movement pattern
(how an action was achieved) - Helps diagnose why environmental success worked or not
KP Examples:
Study
Video/motion feedback (KP) often needs attention
directing/correcting cues to be more effective than KR
What is Bio or neuro-feedback?
Electronic measurement & FB of internal biological process
Provides information that cannot be directly perceived
Examples: EMG, blood pressure, EEG, heart rate, EDA, respiration (wearable technologies –smart watch, fitbit©…)
Are KR and KP mutually exclusive?
Sometimes KR and KP can overlap
- If the goal of the task is a particular movement pattern then the judges’ score is both KR and KP
- If the environmental goal is a target heart rate (HR) during an exercise, then feedback about HR is both KR and KP
Just because we can give detailed feedback (KP) – should we? What problems can arise? (2)
- Can be too much information (overload), especially for new learners
- Often directs attention internally
(rather than on external effects) - Can discourage ‘active’ learning (problem solving)
by being too guiding/prescriptive
Why are external and internal attention both important?
