U3AoS1 - Skill Acquisition Flashcards
Motor (movement) skill
Special form of skills that require movement of the body or limbs
Skill acquisition
The science that underpins movement learning and execution
- more commonly termed motor learning and control
Internal sensory information
Visual, auditory, touch and proprioception
What is proprioception?
Body awareness in time and space
Perception action coupling
Working together of the central nervous system and muscles
- body perceives stimulus via the CNS
- message delivered via muscles to perform
Cues
Relevant and irrelevant
Intrinsic Cue success for learners
Cognitive - not very successful at using intrinsic feedback
Autonomous and associative learners - much better at attending to external cues and using intrinsic information and feedback
Fundamental movement skills
Are the basic movements traditionally associated with activity
Fundamental skill list
- catch
- kick
- run
- vertical leap
- dodge
- leap
- ball bounce
- vertical throw
- punt
- forehead strike
- two - handed strike
Sport specific skills
More complex then FMS and are often a sequence of FMS
What are the stages of learning?
- cognitive
- associative
- autonomous
Characteristics of the cognitive stage
- beginner stage
- learning the mechanics of the skill
- substantial attention required to understand and perform skill
- many errors made
- learners have difficulty attending to external cues
- can’t make use of intrinsic feedback
- mentally trying to comprehend the movement requirements of the motor skill
- attention on movement production
- not yet developed error detection and correction
Performance of cognitive learners
- inconsistent performance
- stiff and unrelaxed movements
Associative Learning Characteristics
- movement patterns become refined
- intrinsic feedback for error correction
- increased awareness of environmental and external cues
- aware of tactical information
Associative learners practice type
Blocked and random practice
Feedback type of associative learners
- Augmented
- Internal feedback beginning to develop
Movements of associative learners
- refine technique and movement pattern
- more consistent, make fewer errors
- can detect cause of some errors
- develop strategies to eliminate them
- more attention to external stimuli
Autonomous stage characteristics
- automatic stage
- little attention required
- can make use of intrinsic senses
- focus on developing strategies and tactics
- automatic skills
- detect and correct errors
- performance variables are small
- focus on tactics
Practice type for autonomous learners
- Random
Feedback type for autonomous learners
Internal - knowledge of performance
What is movement precision referring to?
- fine motor skills
- gross motor skills
What is type of movement referring to?
- discrete
- serial
- continuous
What is predictability of environment referring to?
- open
- closed
What are fine motor skills? (with examples)
The use of small muscle groups to perform skills that require precision.
darts
- hookey
- spin bowler
- golf
- netball
Gross motor skills (with examples)
The use of large muscle groups to perform skills that require strength, power and force
- long jump
- footy kick
- batter in cricket
Define discrete skill (with examples)
- movements of short duration
- clear beginning or end
- kicking a soccer ball
- golf swing
Define serial skill (with examples)
Series of discrete skills linked to create a more complex skill
- triple jump
- tennis serve
Define continuous skill (with examples)
- no clear beginning or end
- movement continues for as long as performer wishes
- repetitive action of same movement
- run
- swim
- cycle
- row
What are closed skills?
- predictable environment
- self-paced
- determined by athlete
What are open skills
- changing/unpredictable environment
- externally paced
Note: some sports more open then others
What is practise distribution?
Ratio of time spent actively practicing compared to time resting and listening to instructions
- frequency/duration
Define massed practice
- Long duration
- Less Frequent sessions
Define distributed practice
- more frequent
- shorter periods
What is blocked practise?
Repetitive practice of the same skills
- isolation of skills
- little practice variability
- direct instruction
- closed skills
Effectiveness of blocked practice
- good for quickly learning mechanics of skills
- skills may not be transferred successfully into game settings
Suitability of blocked practise
- cognitive
- associative
Define random practice
Practicing skills out of sequence (in a random order)
- competition prepared
- develop tactics and strategies
- skills effectively transfer into games/ between sports
- decreased skill errors during games
Effectiveness of Random practise
Skills less likely to break down under pressure
Suitability of random practise
- associative
- autonomous
Define “Feedback”
Information the performer receives about skills or performances
Types of feedback
- Knowledge of results
- Knowledge of performance
- Intrinsic feedback
- Augmented feedback
Define Knowledge of results
Outcome of the skill
