Squill Aquisition Flashcards
Define kinesthesis
The inner sense that gives information about body position and muscle tension
How long is the working memory’s time capacity?
30 secs
What is rough estimate for the maximum number of items the working memory can store at once ?
7
What is a motor programme?
Important information that is stored in the LTM that contains all components of skill
Define long term memory
Received information from the working term memory and has an unlimited store for motor programmes
List methods of how to store information
MALES AND FEMALES CAN RUN CHARITY RACES
• Mental practice
• Association of actions (remember something from around the time learnt)
• Focus (selective attention when learning)
• Chunking (cutting skill up into smaller sections to prevent info overload)
• Rewards
• Chaining (putting movements that link together)
• Repetition
Who made the Schema Theory and when was it made?
Schmidt 1982
What is the Schema Theory ?
Suggests that learning a skill is done by taking existing motor programmes in LTM for core principles and adapting them to suit the environment by using the feedback from the senses.
What are the parameters of schema ?
• Initial conditions - info from environment that needs to be recognised before schema is used. ‘Where am I?’
• Response specifications - info used to assess available options for performer ‘What do I need to do?’
• Sensory consequences - use of senses to to help guide the movement ‘How can I adjust?’
• Response outcome - schema may have to be adapted in the future based on the results of the skill
Define reaction time
The time taken from the onset of a stimulus to the onset of a response. It involves no movement.
Define movement time
The time taken to complete a task after the info processing has taken place (start to completion of movement)
Define response time
The time taken from the onset of a stimulus to the completion of the task
What is the equation for response time?
Response time = reaction time + movement time
Define simple reaction time
Where there is one specific response to one stimulus
Define choice reaction time
Choosing a response from numerous stimuli
What is Hick’s Law?
As the number of of stimuli to choose increases, the longer the reaction time is. Not always a linear relationship though because becoming familiar with the environment will make the response time a little quicker.
What is the single channel hypothesis?
A theory that suggests stimuli can only be processed one at a time
What is the psychological refractory period?
A delay when a second stimulus has been presented before the first has been processed. The performer may ‘freeze’ to sort conflicting info.
Define anticipation
The pre-judgement before a stimulus via ‘cues’ or signals from opponent for example.
Define temporal anticipation
The pre-judgement of WHEN it is going to happen
Define spatial anticipation
The pre-judgement of WHERE and WHAT is going to happen
How does anticipation relate to response time
The correct anticipation reduces response time as the information processing is sped up - movement can occur immediately
List ways to improve response time
• Mental practice
• Train specific stimulus expected in the game (e.g. opponent specific)
• Learn to focus during game to pick up stimulus early (coach make stimulus intense at training)
• Improve fitness for better reaction time - use plyometrics + interval for improved movement time
• Use anticipation - research opponent
What are the characteristics of a skill?
LACEFACE
Learned
Aesthetically pleasing
Controlled
Efficient
Fluent
Accurate
Consistent
Economical
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
e.g. opponents
Define closed skill
A skill performed in a predictable environment
e.g. individual sport , no opponent
Define gross skill
A skill that requires large muscle groups
e.g. rugby scrum
Define fine skill
A skill that requires smaller muscle groups
e.g. throwing a dart
Define self-paced skill
A skill where the performer controls the start and pace of the skill
e.g. taking a penalty
Define externally-paced skill
A skill where an external factor(s) controls the start and pace
e.g. returning a shot in tennis
Define discrete skill
A skill that has a clear beginning and end
e.g. tennis serve
Define serial skill
A skill containing several discrete skills in order to form a more integrated movement
e.g. dance routine
Define continuous skill
A skill with no clear beginning or end and is often the end of or part of the skill that is the start of the new one. e.g. cycling / running
Define low-organised skill
A skill that is easily broken up into parts
e.g. swimming stroke
Define high-organised skill
A skill that is not easily broken down into parts
e.g. volley in football
Define simple skill
A skill that does not require lots of decision making
e.g. forward roll in gymnastics
Define complex skill
A skill that requires a lot of decision making using lots of information when performed
e.g. dribbling in hockey
Define transfer
The effect of learning and performance of one skill on the learning and performance of another
Define positive transfer
When the learning and performance of one skill aids the learning and performance of another skill
e.g. passing in netball and in basketball
Define negative transfer
Where the learning and performance of one skill hinders the learning and performance of another skill
e.g. serving in tennis to serving in badminton
Define zero transfer
When the learning and performance of one skill has no impact on the learning and performance of another skill
e.g. swim stroke and rock climbing
Define bilateral transfer
Where the learning and performance of one skill is passed across the body from limb to limb
e.g. shooting in football with your left foot and then onto your right foot
How can positive transfer be ensured?
• make training realistic to game situations e.g. rugby tackle bags
• ensure a skill is well learned before moving on
• use positive reinforcement when positive transfer is used
Define whole practice
Performing the skill at training, in its entirety
When do you use whole practice?
• when skill is fast, ballistic and discrete
• when kinesthesis is required to perform the whole task
• the skill is simple + highly organised
• performer is in autonomous stage of learning and can cope with demands of whole task
• links between sub-routines need to be maintained
What are the advantages of whole practice?
• allows images of all parts of the skill to be stored in the long term memory as a motor programme so there is a plan in performers mind of how to perform with success
• more realistic than other methods and encourages positive transfer between training and on the pitch
• keeps the skill consistent and helps performer keep good habits and able to perform automatically
What are the disadvantages of whole practice ?
• learners in the cognitive stage may not be able to cope with the demands of performing the whole skill
• performer may get fatigued doing whole skill with no break
• could suffer from info overload
