Skills acquisition P2 Flashcards
Skilled Movements
-Made up of 2 elements, Cognitive - the mind and Motor, the body.
Skills which are; Learnt, Consistent, Goal-directed, Aesthetic, controlled and efficient
Classification continuum
- used to classify skills in sports, by six continuum:
- Complexity
- Environmental
- Pacing
- Muscular involvement
- Continuity
- Organisation
Complexity continuum
Simple or Complex?
Simple = little/no decision making
Complex = Decision making
e.g. Simple is a 100m breastroke, Complex is rugby tackle
Environmental continuum
Open or Closed?
Open = effected by sporting environment, use perception
Closed = not effected by sporting environment, no use of perception
e.g. Open is deciding when to take a football penalty kick, Closed is a 100m sprint
Pacing continuum
Self-paced or Externally paced?
Self Paced = at control of performer, rate of execution is decided before execution
Externally Paced = controlled by factors out of control
e.g. Self is high jump & Externally paced is returning a serve in tennis
Muscular Involvement Continuum
Fine or Gross?
Fine = uses small delicate muscle movement
Gross = uses large muscle groups
e.g. Fine is darts and gross is sprinting
Continuity continuum
Discrete, Serial or Continous?
Discrete = short, clear begging and end
Serial = several discrete elements
Continous = ‘kinaesthetic’, no clear beginning or end
e.g. discrete is 80m hurdles, serial is netball shoot and Continous is swimming a 100m race
Organisation continuum
Low organised or highly organised?
Low organised = can be broken down into subroutines
Highly organised = can’t be broken down into subroutines due to speed of execution
e.g. LO is netball shot and HO is pole vault
Whole practise
- Full skill is practiced at once
- GOOD for Highly organised, simple, discrete and closed skills
e. g. Pole vault
Part practise
- Skill broken into subroutines and then practised
- GOOD for low organised, complex and dangerous skills, it promotes safety
- keeps links between subroutines
e. g. Rugby tackle, hug and then pull ring of steel down to knees
Whole-Part-Whole Practise
- Skill is performed fully, then an element/subroutine is practised and then skill is practiced fully.
e. g. A Handstand
Progressive-Part practise
- involves learning several subroutines to form a whole movement.
- each part is practised with the next link added each time, then pieced together - ‘Chaining’
- good 4 low organised
Massed practice
- no rest intervals between component of training
- Promotes high levels of fitness and motivation
- good for motivated, fit players, simple and discrete skills.
Distributed practice
- rest intervals given to allow for recuperation.
- good for unfit, beginners and unmotivated players.
Varied Practise
- use of different methods to achieve learning goals in different situations.
- gives ability to adapt a skill with variations
- good for open skills, allows player to make decisions, Complex skills as it develops perception
Fixed Practise
- Involves stable and predictable environment, conditons remain fixed.
- Good for closed skills due to no environmental changes
Transfer of learning
-Learning and performance of one skill can be affected by the learning and performance of another
Positive transfer
-learning one task is enhanced by learning another task
- e.g. learning a golf stroke may be enhanced by the fact the player plays cricket.
- involves similar action & skill set
Negative transfer
- Initial stage of learning
- learning of one skill is hindered by learning another skill.
Proactive transfer
- a previously learnt skill is used to help one being developed
e. g. basketball passes can help learn netball passes
Retroactive transfer
- a previously learnt skill interferes with a skill already learned.
e. g. a netball player returns to netball after playing basketball, there may be a negative affect on their netball skills.
Bilateral Transfer
- when skills are transferred from one limb to another limb across the body.
- coaches encourage BT as it improves skills
e. g. a coach will encourage players to practice shooting on both sides.
Stages of learning
- Fitts & Posner
- We pass through 3 stages of learning
- if we understand the learners requirements we can provide suitable guidance and feedback
1st stage of learning
- Cognitive phase
- a beginner tries to work out what is required to perform a new movement e.g. A Netball shot
- Takes time to check and think about the movements
- Coach use manual and mechanical guidance, focus on extrinsic & positive feedback -> encourages
- Shortest phase - a trial and error
2nd stage of learning
-Associative phase ‘‘practise phase of learning’’
The learner compares their performance level to a elite athletes performance level
-the longest phase, most don’t progress out of it
-long practice periods & good feedback ->correct errors & perfect skill.
-Conscious control
E.g. a netball player can change her passing by stepping into the pass and keeping her elbows tucked in
Mental framework
-Builds up a mental framework
Motor programmes are coded into the memory
Use of intrinsic feedback to alter level of skill
Use verbal and visual guidance
3rd phase of learning
-Autonomous phase
Movements almost automatic -> due to practice & feedback
-Concentrate on finer details of task
Performance completed with maximum efficiency
-phase for experts -> continue to practise to remain
Strategies
used by coaches to help layers progress from early cognitive phase to final autonomous phase of learning.
Learning -> permanent change in behaviour & movement patterns
Operant conditioning (Skinner)
-Behaviourism approach, associationism
Gain feedback from a performance -> strengthens/ weakens our response to a given stimulus
Stimulus -> good response = more likely to repeat
Stimulus -> bad response = less likely to repeat
learn through trial and error -> shapes environment by manipulating behaviour & receiving rewards/reinforcement
used in teaching motor skills ->practise using feedback = stronger correct response + change incorrect responses
Learn through associating the correct response with a stimulus
Strategies to strengthen S-> R response
- Use positive reinforcement e.g. praise
- Allow early success -> develops confidence in performer
- Use mental rehearsal - continuously develops a automatic response to the stimulus
- Use whole practice -> promote fluency
Reinforcement
Complete reinforcement = a performer is rewarded everytime a correct action is produced, quickly strengthens S -> R bond
Partial reinforcement = rewarding every now and then, takes longer to strengthen S -> R bond but more valued
Negative reinforcement = performer begins to make mistakes, a coach will withdraw praise
Negative punishment - use carefully to avoid lowering confidence but trying to prevent repetition of an unwanted response.
Thorndikes laws
Link to operant conditioning, suggest that strengthening the S -> R bond will depend on:
- Law of exercise - repeating the S ->R connections is more likely to achieve the desired response
- Law of effect - if the response is followed by a pleasant consequence it is likely to be repeated, but if followed by unpleasant consequences likely to be stopped
- Law of Readiness - the performer must be physically & mentally ready to complete a task
