A procedure in which a skill is broken down into parts that are practiced separately.
What task would likely benefit most from part practice?
A serial task with low component interaction
Reference of Correctness
An awareness of how a movement should feel when it is performed correctly
What is Feedback during the learning experience classified as?
Augmented (extrinsic) or Intrinsic (inherent)
What is Knowledge of Performance (KP)?
Augmented feedback about the movement pattern the learner has just made -High jump "your approach run was too fast"
What is Knowledge of Results (KR)?
Augmented feedback about the success of an action with respect to the goal -Time in a race, score in gymnastics
How are Attention-Focusing Properties effective?
Augmented feedback can be used to direct the learner's attention to purpose of practice. -Interval vs external focus of attention -External: something outside of body
How is augmented feedback in the conceptual model processed?
Augmented feedback is always processed consciously.
T/F: To maximize motor learning, an instructor of a motor skill should always attempt to maximize a learner's performance during practice.

What is Summary Feedback and Bandwidth Feedback effective for?
Considered to be an effective strategy for reducing the relative frequency of augmented feedback.
What is Descriptive Feedback?
Describes action
Guidance
Directing a learner through task performance -Can be physical, verbal, or visual
Examples of Direction of Error and Magnitude of Error
Direction: "You are off the target to the right..." Magnitude: "...by 20 cm." -Only give learner one (direction) so they can change -Avoid overly precise feedback to novices
Describe Autonomous Stage
Expert performance
What is Feedback for Learning?
Feedback is a critical motor learning and performance variable.
What is Summary Feedback?
Feedback that is given after a series of practice trials that provides the learner with information about their trials -Average of the trials
What is Simulation Fidelity?
Fidelity refers to the extent to which the simulator mimics the criteria task
When should variable practice be used?
Fixation stage of learning -Variable practice has a stronger positive effect on children than adults
Does guidance have a stronger influence on performance or learning?
Guidance is a strong positive performance variable, but a weak positive learning variable.
What is the appropriate practice/instructional strategy to use early in the cognitive stage of learning:
Guidance is most effective early in learning
Motor Learning
Motor learning is a set of processes associated with practice or experience leading to a relatively permanent change in the capability for skilled performance
What should be the timing of Extrinsic Feedback?
How much time passes after a trial before feedback is given doesn't make much difference -The one exception is to avoid instantaneous feedback

How to do it
Which frequency of feedback enhances learning?
Increasing the absolute frequency of feedback enhances learning.
What is Informational Properties of Augmented Feedback?

What is bad about Dependency- Producing Properties?
Learners can become dependent on augmented feedback.
Physical Practice Techniques: What is simulation practice?

How does Summary Feedback work?
Maximizes the amount of information provided to the learner, without the dependency-producing effects of providing feedback after every trial -Encourages learner to use intrinsic feedback

Negative Transfer of Learning
Positive or Negative Learning
Negative learning= bad habit
Negative/Positive Transfer of Learning
Negative transfer is possible, but in terms of motor skill acquisition, when transfer occurs, it is usually positive.

Component (part-to-part) Interaction in Serial Skills
The extent to which one part of the skill influences other parts of the skill -The lower the component interaction, the more effective part practice will be
What is Transfer of Learning?
The gain or loss in a person's proficiency on one task as a result of practice on another task
The effectiveness of part practice depends on:
The nature of the target skill: -Serial skills -Continuous skills -Discrete skills
What is Specificity of Learning?
The notion that what you learn depends largely on what you practice.
What is Relative Frequency of Feedback?
The percentage of practice trial attempts for which feedback is given -20 trials, 10 of which are followed by feedback, the relative frequency=50%
