Lecture 29 - Providing feedback during motor learning Flashcards
What is feedback?
information about movement patterns or outcomes the nervous system can use to guide future movements
What is augmented feedback?
information about a movement outcome. this additional feedback comes from an external sorce and augments intrinsic feedback
Where is augmented feedback from?
an external source
Augmented feedback can be…
What are the properties of augmented feedback?
- provides information to correct erros
- can be motivational
- can focus attention
- can produce dependance
What are 4 things to keep in midn when providing feedback?
- what type of deedback should i provide
- how much feedback should i give
- when should i give feedback
- how precise should feedback be
What is knowledge of results (KR)?
augemented information about success (yes or no) or degree of success of an action relative to the goal of the task
What is knowledge of performance?
augmented information about movement patterns while performing a motor task
What are similarities between KR and KP?
- verbal
- augmented
- usually provided after movement
What are differences between KP and KR?
KP
- information about movement pattern
- usally distinct from inherent feedback
- usually kinematic information
- often provided in everyday activites
KR:
- info about goal outcome
- often redundant with inherent feedback
- usually provided as a scor
- often used in lab research
What is the best practice in terms of amount of feedback?
Tapered feedback
What is tapered feedback?
frequent feedback during early learning and progressively withdraw feedback as learner becomes skilled at task
What is instantaneous feedback?
Feedback provided immediately after movement that informs learners about the trial that was just completed
What is delayed feedback?
Feedback provided a short period of time after movement that informs learners about the trial that was just completed
What can happen with instantaneous feedback?
Learner can become dependent on feedback
Does instantaneous of delayed KR show better retention of learning?
Delayed
Is is best to let the learner choose when they want feedback?
Yes, learning and retention are highest when the learner determines when they receive feedback
Is retention high when KP is given after the trial is completed?
yes
When should you give feedback?
after the trial or skill is completed
What is summary feedback?
feedback provided after a series of trials that informs learners about each of the attempts in the series
What can summary feedback help prevent?
the learner from becoming dependant on feedback
What can summary feedback prevent or minimize?
feedback-dependency
What might summary feedback force learner to focus on?
proprioception and visison to detetc their own errors
What might summary feedback produce?
more stable movement patterns and strengthen motor programs
What does summary feedback give the learner?
More reliable information about what to change and how to change it
What is average feedback?
feedback provided after a sereies of trials that informs learners about their average performance
What might average feedback help prevent or minimize?
feedback dependency
What may average feedback help the instructor develop?
Better understanding of what kind of errors the learner typically makes
What is average feedback likely to provide?
more reliable information about what needs to change and how to change it
