Chapter 2- Skill Acquisition (Paper 1) Flashcards
Define skill
The learned ability to bring about predetermined results with the minimum outlay of time, energy or both.
Define open skill
A skill performed in an unpredictable environment.
Define closed skill
A skill performed in a predictable environment.
Define gross skill
A skill that uses large muscle groups.
Define fine skills
A skill that uses smaller muscle groups.
Define a self-paced skill
When the performer controls the start and the speed of the skill.
Define an externally-paced skill
When the performer has no control over the the start and the speed of the skill.
Define a discrete skill
A skill that has a clear beginning and end.
Define a serial skill
A skill that contains several discrete skills in order to make a more integrated movement.
What is a low organised skill?
A skill that is easily broken into parts (discrete subroutines).
What is a high organised skill?
A skill that is not easily broken into parts (closely integrated subroutines).
What is a simple skill?
A skill that requires few decisions when being performed.
What is a complex skill?
A skill that requires decision making using lots of information when performed.
What is the difference between a skill and an ability?
A skill is something you learn where as an ability is something you are born with.
What are the characteristics of a skill?
A- Aesthetically pleasing C- Consistent E- Efficient F- Fluent A- Accurate C- Controlled E- Economical
Why is the classification of skills used?
It is used to group together different types of skills with similar characteristics. In sport we use a continuum to classify skills. This allows for skills to be analysed and placed between two given extremities, according to how they match the analysis criteria being applied.
What are open and closed skills categorised into?
Environmental influence.
What are the characteristics of open skills?
- Affected by the environment
- Externally-paced
- Require adaptations and decisions.
What are the characteristics of closed skills?
- Self paced
- Unaffected by environment
What are gross and fine skills categorised into?
Muscle involvement
What is the order of the skills in continuity?
Discrete -> Serial -> Continuous
What is a continuous skill?
A skill that has no obvious beginning or end
What is a low organised skill also known as?
Incoherent
What is a highly organised skill also known as?
Coherent
What is transfer?
The effect of learning and performance of one skill on the learning and performance of another.
What is positive transfer?
When the learning of one skill helps the learning of another.
What is negative transfer?
When the learning of one skill hinders the learning of another.
What is zero transfer?
When the learning of one skill has no impact on the learning of another.
What is bilateral transfer?
When the learning of one skill is passed across the body from limb to limb.
When does positive transfer tend to occur?
Transfer tend to occur when two skills have a similar shape and form. This is because the actions of the two skills are similar so the movements of one help the other.
When does negative transfer tend to occur?
Tends to happen when there might be some familiarity with the environment in which the two skills are performed and this familiarity might cause confusion when the actions of the two skills are not the same.
Give an example of negative transfer
The wrist flexibility required for squash or badminton is likely to lead to interference when learning a tennis drive where a firm wrist is needed.
When does zero transfer tend to occur?
When two skills have no similarities and no aspect of confusion and does therefore not affect one another.
What is an example of zero transfer?
Often when skills are completely different such as rock climbing and a forehand drive.
What are the different types of presentation of practices (methods of presentation) ?
- Whole
- Progressive part
- Whole-part-whole
What is whole practice?
Practicing the skill in its entirety.
What is whole-part-whole practice?
Assessing the skill, identifying a weakness a to practice, then putting the skill back together.
What is progressive part practice?
Practicing the first part of a skill then adding parts gradually. Sometimes called chaining.
What is chaining?
Linking the sub-routines, or parts of a task, together in order when practicing. The first two parts are learned, then the third part is added; that is learned and then added to the first two, and so on.
What is massed practice?
No rest intervals
What is distributed practice?
Rest intervals.
What is mental practice?
Going over the skill in the mind without movement.
What is varied practice?
Changing the practice type and the practicing drills.
When is whole practice used?
- Fast
- Closed
- Discrete
- Self-paced
- Simple
- High organised
What are the advantages of using whole practice?
- Fluency
- Develops kinaesthesis or understanding (motor programme)
- Keeps link between sub-routines
- More realistic
What are the disadvantages of using whole practice?
- Too much information
- Beyond the capabilities of the performer
- Not for beginners
- Possibility of fatigue
What is an example of a skill taught by whole practice?
-Tennis serve
When is progressive part practice used to learn a skill?
- Complex - a complex skill can be isolated which takes pressure off a performer
- Serial - chaining can occur
- Externally paced
- Low organised - can be broken down
What are the advantages of using progressive part practice to learn a skill?
- Keeps links between parts
- Gives motivation (success in stages)
- Reduces danger
- Reduces fatigue
- Reduces demands
- Focuses on weaknesses
What are the disadvantages of using progressive part practice to learn a skill?
- Time consuming
- If the first part is incorrect, all is lost
- Negative transfer between each sequence of the skill
- Ignores links between sub routines
What is an example of a skill learnt by progressive part practice?
A dance routine
When is whole-part-whole practice used to learn a skill?
When the skill is:
- Complex
- Fast/ballistic
- Difficult to isolate parts of skill
- Performer has a specific weakness
- Beginner doing a complex task
What are the advantages of using whole-part-whole practice to learn a skill?
- Shows weakness and corrects it
- Provides motivation when success is achieved after a long standing weakness has been corrected
- fluency and integration of the sub routines can be maintained
What are the disadvantages of using whole-part-whole practice to learn a skill?
- Time consuming
- Some skills cannot be broke down
- May produce negative transfer if the skill is not integrated back within the same training session.
What is an example of a skill learnt by whole-part-whole practice?
Golf swing when the performer has a poor grip.
When is massed practice used to teach a skill?
When the skill is:
- Discrete
- Simple
- Closed
- Self paced
What are the advantages of using massed practice to teach a skill?
- Forms motor programmes
- Increases fitness
- Enhances over training
- Good for habitual responses
- Efficient
What are the disadvantages of using massed practice to teach a skill?
- No time for feedback
- Fatigue
- Too demanding
When is distributed practice used to teach a skill?
When the skill is:
- Continuous
- Complex
- Open
- Serial
- Externally paced
What are the advantages of using distributed practice to teach a skill?
- Allows recovery
- Less mental pressure
- Allows mental rehearsal/ feedback
- Reduces danger
- Motivation from praise
What are the disadvantages of using distributed practice to teach a skill?
- Time consuming
- Negative transfer
Give an example of when massed practice is used (2)
- Basketball players throwing free throws (at different baskets)
- Bowlers bowling at wickets (different wickets)
Give an example of when distributed practice is used
A swimmer practicing stroke technique in training.
When is varied practice used to teach a skill?
When the skill is:
- Complex, easy part first then add
- Open
- Externally paced
What are the advantages of using varied practice to teach a skill?
- Builds a scheme
- Gives motivation
- Allows adaptation of skills to changing environments
What are the disadvantages of using varied practice to teach a skill?
- Time consuming
- Possibility of negative transfer unless the changing drills are integrated into the aims of practice sessions.
- Fatigue
- Too demanding
Give an example of when varied practice can be used.
Players practicing a football pass.
When can people practice using mental practice?
It can be done between practices as part of training programme or before a major event.
What skills use mental practice?
When skills are:
