Skill Acquisition Flashcards
What are skills ?
Skills are learned, and not inherited genetically
What are the characteristics of skilled movement ?
Aesthetically pleasing
Consistently correct
Efficient
Fluent
Accurate
Controlled
Economic
+ Goal directed
+ Pre-determined
+ Adaptable
What is the Open - Closed continuum about ?
How environmental conditions affect the skill
What is an Open skill ?
The environment changes frequently and lots of decisions need to be made
What is a Closed skill ?
The environment is predictable and few decisions need to be made
What is the Gross - Fine continuum about ?
How precise a movement is and the amount of muscular movement needed
What is a Gross skill ?
Using lots of different muscle groups or large muscle groups
What is a Fine skill ?
Using very small muscles or few muscles
What is the Discrete - Serial - Continuous continuum about ?
The relationship between the subroutines and is the identification if the beginning and end of the movement
What is a Discrete skill ?
Clear start and end to the movement
What is a Serial skill ?
A series of linked discrete skills
What is a Continuous skill ?
No clear start and end - series of repeated subroutines
What is the Self paced - Externally paced continuum about ?
The level of control the performer has over the timing and speed of the skill
What is a Self paced skill ?
Performer has control over the start and speed of the performance
What is an Externally paced skill ?
Performer has no control over the start and speed of the performance
What is the High - Low continuum about ?
How easily a skill can be broken down into subroutines
What is a Low organised skill ?
Easy to break down into sub-routines
What is a High organised skill ?
Hard to break down into sub-routines
What is the Simple - Complex continuum about ?
The amount of information you need to complete the skill
What is a Simple skill ?
A skill that requires few decisions and little information to process
What is a Complex skill ?
A skill that requires many decisions and lots of information to process
What is Positive transfer ?
Previously learned skills help the development of new skills
What is Negative transfer ?
Previously learned skills hinder the development of new skills
What is Bilateral transfer ?
Transfer of learning from one limb to another - kinaesthetic awareness can improve this
What is Zero transfer ?
Previously learned skills have no impact on the learning of new skills
What is whole practice ?
The complete skill is practiced in its entirety, without attempt to break it down into subroutines
When may a coach use whole practice ?
Simple, closed, discrete, high skills
When skills are safe
When the performer is motivated, fit enough and an expert
What are the advantages of whole practice ?
Get the feel of the whole movement
More realistic
Makes skills more consistently correct
Maintains links between the subroutines
What are the disadvantages of whole practice ?
Fatigue
Safety
Beginners may struggle
Too much info to process
What is whole part - whole practice ?
Performer tries the whole skill, it is then broken down into parts, each part is practiced in isolation, the parts are reintegrated and the skill is practiced as a whole again
When may a coach use whole part - whole practice ?
Serial, complex, low skills
Dangerous skills
What are the advantages of whole - part - whole practice ?
More fluent skill
Danger reduced
Fatigue less likely
Immediate feedback
What are the disadvantages of whole - part - whole practice ?
Time consuming
Loss of kinaesthetic feel
Can’t be done with all skill types
What is progressive part practice ?
Breaking down the skill into a series of parts and then ‘chaining’ them together one at a time
When may a coach use progressive part practice ?
Dangerous skill
Serial, low and complex skills
What are the advantages of progressive part practice ?
Rest between stages
Reduces danger
Success at each stage
Confidence as each part is perfected
What are the disadvantages of progressive part practice ?
Time consuming
Could disrupt flow of movement
Not a feel for whole movement
If first part was incorrect the rest of the skill is incorrect
What is massed practice ?
Learner practices a skill continuously without rest intervals
What are the advantages of massed practice ?
Improve fitness level and save time
Good for experienced performers
Stimulates performance conditions where fatigue is an element
Good for establishing habitual skill
What are the disadvantages of massed practice ?
No time for feedback
Not suitable for dangerous tasks
Can cause fatigue and demotivation
Beginners affected by lack of concentration and attention
Boredom
Negative transfer
What is distributed practice ?
Practice sessions that include rest intervals
What are the advantages of distributed practice ?
Help maintain motivation
Allows for mental rehearsal
Rest allows for recovery and feedback
Less dangerous
Research has shown this to be the most effective form of practice
What are the disadvantages of distributed practice ?
More time consuming
Skills may have to be reintroduced after each break
May lead to frustration/ de-motivation when rest intervals delay practice
What is variable practice ?
A skill practiced in a constantly changing environment
What are the advantages of variable practice ?
Develops schema, decision making and perceptual skills
Develops subroutines
Adapt techniques to the changing environment
Can improve the speed of learning
What are the disadvantages of variable practice ?
Time consuming
Negative transfer if skills are not correctly performed
Need to already have a well learned motor programme in a fixed environment
What is mental rehearsal ?
Performer goes over the movement in their mind/ cognitively without any movement occurring
What are the advantages of mental rehearsal ?
Can focus attention
Adaptations are stored in memory
Rehearse complex skills / strategies
Used in cognitive stage
Experts use it for emotional control and reaching optimum arousal levels
What are the disadvantages of mental rehearsal ?
Not effective with simple skills
Used by itself, its not effective as physical practice
What is learning ?
A permanent change in behaviour that occurs as a result of practice
Linked to practice or experience
Relatively permanent
Not a ‘fluke’ or one-off occurrence
What is performance ?
A more temporary occurrence, influenced by other factors such as anxiety and nerves that may be felt by a player just before a major game
Not necessarily repeated
What are the features of the cognitive stage ?
Lots of errors made
Create a mental picture of the skill
Performer observes a demonstration or is given verbal instructions
What are the features of feedback in the cognitive stage ?
Extrinsic feedback from the coach
Positive
Knowledge of results and performance (technique and outcome of skill)
What are the features of the associative stage ?
Longer than the cognitive stage
Develop movement patterns through practice and feedback
Movements start to become smoother
Length of time in this phase is affected by ability, complexity of skill, practice amount and quality of feedback
What are the features of feedback in the associative stage ?
Extrinsic moving towards intrinsic
Positive and negative
Knowledge of results and performance
What are the features of the autonomous stage ?
Performer is so efficient they can focus on other factors such as tactics
Skill is completed almost without conscious thought
Correct mistakes through kinaesthesis
What are the features of feedback in the autonomous stage ?
Intrinsic feedback
Detailed feedback
Positive and negative
Knowledge of results and performance (quality of technique and outcome of skill)
What is positive feedback ?
Tell the performer what went well
What is negative feedback ?
Tell the performer what went wrong/ didn’t work well
What is knowledge of results ?
Feedback the performer gets about the outcome of the action
What is knowledge of performance ?
Feedback the performer gets about the quality of performance or technique
What is extrinsic feedback ?
Feedback from outside of the performer
