Lecture 5 Flashcards
What does feedback allow you to do?
Helps you interpret the motor action or understand sensory information. Want people to eventually use it to detect their own errors.
Why is intrinsic feedback beneficial?
- Its inherent in all movement.
- sensory -perceptual feedback helps us determine if we did a movement correctly based on the efferent copy.
What is your efference copy?
Before we move, we have a sensory prediction of what the action should look like and if you’re successful.
What does an optimal KR schedule achieve?
Minimise mismatch between what you expect and what action you actually did.
What are the 2 types of KR? Which one is better?
Essential KR - good because you reduced some uncertainty.
Redundant KR - bad because its feedback about things we already know. Does not help skill acquisition or uncertainity.
What is the difference between KR and KP?
KR - providing info based on an outcome or environmental goal.
KP- providing info based on technique regarding a movement pattern.
What does the Law of Effect state?
KR is needed to reinforce behaviour and there is a performance decrement without KR.
What does the Instrumental Learning Paradigm?
There is an association between a stimulus and behaviour you want to enforce.
What is concurrent augmented feedback? What type of effect does it have on learning?
Concurrent AF is when you give feedback while someone is performing a motor task. It has a negative effect on learning but can be positive if the task is complex.
Why is it important that there is a KP/KR delay?
Want to give learner’s time to interpret the feedback and estimate how well you did.
What is the length of KR/KP delay? Is there criteria.
5-20s but could be up to 1 min. Nothing else can be done during this period.
What is the benefit of having individuals estimate how well they did before getting feedback.
Strengthens their detection of errors and interpretation of intrinsic feedback.
Why is it important to have an augmented feedback schedule?
Easiest to use in a practical setting and place demand on cognitive effort.
What does the guidance hypothesis tell us?
- frequent KR promotes dependency.
- corrections are maladaptive
- error detection and correction is blocked.
You want every trial to be a problem solving event because there’s always going to be variability.
How many trials can you up to for summary KR for a simple task?
20 tasks.
