Skill Acquisition 2.2 2 Flashcards
(22 cards)
What are the advantages and disadvantages of visual guidance?
Advantages:
- Visual guidance can be used to highlight a specific weakness (e.g. a coach can stop the performer and show learner exact position they need to be in
- VG tries to show what skill should look like as a result of practice
- It creates a mental image
Disadvantages:
- Demonstration must be completely accurate, otherwise may be copied incorrectly & performer may not have ability to perform demonstration if coach does not ensure success
- Also if too much information is given, the performer may become confused
What is verbal guidance?
- An explanation of the task
- Nearly always used in conjunction w visual guidance
- Helps to build correct mental image in memory
- VG can also be used for experience player, when technical & detailed advice is given to complement actions in practice or advice given during performance
What are the problems and considerations when using verbal guidance?
- If too much info is given to perfromer it may cause confusion & place too much demand on memory
- Performer may loose concentration unless coach makes verbal info brief, relevant & meaningful
- Language used by coach should be understandable
What is manual guidance?
- Involves physical support
What are the advantages & disadvanatges of manual guidance?
Advantages:
- Very important of helping to eliminate danger e.g. supporting a gymnast will prevent a fall
- Helps build confidence for performer who may not be able to gain feel of the whole task without help & support from MG
- Fear & Anxiety of difficult/dangerous tasks may be reduced if support is on hand to help performer.
Disadvantages:
- Can have a detrimental effect on performance if over used
- Permissions
- Too much reliance on physical support could begin to interfere with feel of task
What is mechanical guidance?
- An artificial aid used to help performance e.g. a trampoline harness
What are the advantages of mechanical guidance?
- Builds confidence- the successful completion of the task even though assistance was given, gives performer sense they can do it
- Eliminates danger & can prevent injury
- Can be used with disabled atheletes or those recovering from injury
What are the problems with mechanical guidance?
- If used for too much time, mechancial guidance can interfere with feel of task
- Performer might depend on it too much, so a sense that task cant be completed without artifical help couls promote loss of conifdence
- Motivation could be lost if performer thinks skill is not being performed independantly
What is operant conditioning?
- The use of reinforcement to ensure that correct responses are repeated
Part of the behaviourist theory
Based on work of Skinner who obserevd rats in a cage called skinners box - Cage was fitted with a mechanism that delivered food to the rats everytime it was touched
- At first rats hit the mechanism by accident but quickly learnt to hit the mechanism to gain a reward
What are the 3 characteristics that operant conditioning is characterised by?
- Based on trial and error learning
- Coach might manipulate environment when using operant conditioning
- Shapes behaviour by using reinforcement
What prinicple does operant conditioning work on?
- Reinforced actions are strengthend and that incorrect actions can be weakened
How does operant conditioning & the stimulus response bond work?
- OC works by strengthening the link between the stimulus and the response ( known as the S-R bond)
e.g. in a game of badminton if a shuttle cock is reuturned high in air the best response would be to do a smash shot.
What is postive reinforcement?
When a pleasant stimulus is given to increase the likelihood of a correct response occuring again in the future.
e.g. praise/reward
What is negative reinforcement?
- Promotes correct actions occuring to a stimulus by taking away an unpleasant stimulus when performer does it right
e.g. negative critisism is removed when performer does well
What is punishment?
When a coach gives an unpleasant stimulus to prevent incorrect actions from happening again.
e.g. a performer recieveing a red card in football - so dont do those actions again
What was Banduras theory?
- Suggests that both acceptable & unacceptable behaviour can be learned by watching then copying other people
What 4 processes did Bandura suggest where a performer is more likely to copy a model?
- Attention- Make sure performer takes note of relevant cues, more attractive the demo is to player more likely it is to be copied
- Retention- Ability to remember information & recall it from memory system. Make sure the learner is able to recall demonstration from memory by breaking any info given into chunks & repeating it.
- Motor Production- Making sure player is capable of physically copying the demonstration i.e giving a task thats set at same level of ability. Player should be given time to practice & learn well before moving onto next part of task
- Motivation- The drive needed to copy the demonstration. Motivate learner by giving praise,rewards etc
What was Vygotskys social development theory?
- Interaction with others plays a vital role in learning
- Interaction with others can produce learning by social development
- In sport – skills can be learned from others such as teacher/coaches/peers
- These are known as more knowledgeable other (MKO)
The MKO gives direct examples & advice & demonstrates values and actions - During development the skills are learned from the coach by a process called inter-psychological learning
Once external advice has been observed they will use it to learn
- The learning from within, after the inter-psychological stage is called the intra-psychological stage
- Vygotsky also suggested that learning can be constructed in stages
- The learner will use 3 stages to construct learning
What is constructivisim that Vygotsky suggested?
- Build on what you know
- Working with others helps to develop skills
- Learning from actions of those, more experienced
- During intra-psychological learning the learner will evaluate own level and assess what is required to move onto next level
- MKO/coach may intervene to give advice as skills advance
- 3 levels of performance to assess possible improvements.
- Learner uses zone of proximal development to assess next stages of learning the skill.
What are the 3 stages of proximal development?
- What can I do alone?
- What can I do with help?
- What can I not yet do?
What is insight learning (Gestaltist theories)?
- Performer uses existing knowledge to form an idea of how to deal with a problematic sporting situation
- General knowledge- put into practice
Example: In 3000m race, runner knows other athletes have a strong finish, so starts quickly to try to catch them out, if this works the same tactic will be used again.
- If tactic works it will be used again in the future
What are the features of insight learning?
Features:
- Concentrates on the whole task – useful in realistic situations
- May provide self-satisfaction & intrinsic motivation as performer has worked out the tactic by themselves
- Not trial & error – poses questions to the performer, encourages performer to think for themselves & develop the cognitive process
- By working out problems, athlete learns to use the cognitive process, thinking is encourgaged & performer may begin to think about use of their skills in competitive situations in the future
- Insight approach may not be suitable for all learners- a novice may not have enough experience to generate their own solutions to sporting problems.
