quiz #4 Flashcards
what is feedback?
information provided about performance of a task
used as a basis for improvement
task intrinsic feedback
Sensory feedback which is
naturally available during
performance of a skill
augmented feedback
Information pertaining to
performance which is added
by an external source
knowledge or results
externally presented information
about the outcome (ex. outcome/criterion)
knowledge of performance
information about movement
characteristics and performance
examples: movement pattern, speed, distance
t or f: can augmented feedback (kr and kp) be descriptive (assessment) and prescriptive (correction)
true - through verbal, video, tactile, FB
KP - Error Detection
Actively engages the learner
in the cognitive processes of
error detection/correction
KR - positive reinforement
motivates the learner
what are the considerations with augmented feedback?
produces motivation, energies the learner to increase effort
provides information about errors as a basis for corrections
directs the learner’s attention toward the movement or the movement goal
creates a dependency, leading to problems at feedback withdrawal
when is KP more effective than KR?
- When skills require specificity
- When coordination must be improved/adjusted
- When KR is redundant with task-intrinsic feedback
when is KR more effective than KP?
- To confirm learner’s assessment of task-intrinsic feedback
- To determine the outcome when task-intrinsic feedback not available
- To motivate continuing practice
- To promote discovery learning by trial and error
terminal
at the end
concurrent
during performance
T OR F: is terminal almost always effective?
TRUE
When is concurrent most effective?
1) task-intrinsic feedback is low
2) learner has poor reference of correctness
3) learner is unsure what to do
T OR F: instantaneous feedback resulted in poorer performance than
delayed feedback in both acquisition and retention.
TRUE
T OR F: Is knowledge of results supported by research
FALSE
what is the negative effect?
if learner focuses on another’s performance or engages in a secondary task
unfilled KR-delay
rest period
filled KR delay
other positions produces negative interference
T OR F: post KR period of 5- 60 seconds appears to be beneficial
TRUE
The Guidance Hypothesis
predicts guiding properities of augmented feedback are helpful for motor learning to reduce error, but it’s detrimental when relied upon.
T OR F: Is KR OR KRP 100% optimal?
FALSE NOT OPTIMAL
bandwidth feedback
feedback given within a pre-defined range of error - a summary of feedback about previous trials
what are methods to reduce freqeuncy of FB
- performance based bandwidths
- Self- selected FREQUENCY (asking for help when needed)
- summary feedback (feedback after a certain # of trials)
