Q

what is selective attention and how does it benefit the performer?

A
  • Selective attention involves filtering out irrelevant information from the display.
  • prevents information overload allowing quicker decision making
  • the correct information must be selected to make the correct/best decision

Q

methods of improving selective attention

A
  • making key/important stimuli more intense e.g. increasing size, brightness or volume of the stimuli
  • optimising arousal levels allowing more focus
  • practicing with distractions -> performer gets used to ignoring irrelevant stimuli
  • use of mental practice -> know which are the relevant stimuli quicker

Q

Describe the decision-making stage in a general information processing model

A
  • DCR is used (detection of relevant info, comparison with memories, recognition of most appropriate response)
  • appropriate response is chosen from memory (if necessary the STM will refer to LTM). This response is likely to be one used in a similar situation previously. Therefore a more experienced performer has quicker decision making
  • allows best course of action to be taken

Q

what is the phonological store (PS)?

A
  • holds information in speech form
  • inner ear
  • spoken words enter the store directly whereas written words must be converted into spoken form first

Q

what is the episodic buffer?

A
  • sequences events and provides context to the information from the phonological loop and visa-spatial sketchpad
  • sends the information to the LTM to decide the best course of action

Q

what are strategies for improving information retention (in the LTM)?

A
  • use of rewards to motivate the performer to want to remember correct actions
  • use of mental practice helps to store info in memory especially for remembering the correct sequence of a serial skill
  • repetition can be used to ensure the skills are coded as motor programmes
  • breaking the task down

Q

features of the working memory

A
  • has a limited capacity -> too much info can risk important things being lost or disregarded by performer
  • has a limited time scale -> can only hold information for around 30 seconds

21
Q

what is the long-term memory

Study These Flashcards
A

receives information from the working memory and has an unlimited capacity for the storage of motor programmes.
- can send information back to the working memory

22
Q

what are motor programmes?

Study These Flashcards
A

A set of movements stored in the memory that specify the components of a skill

23
Q

What is the schema theory?

Study These Flashcards
A

Suggests that rather than use a structured set of movements to develop skills, the core principles can be taken from an existing motor programme and then adapted, using some information from the environment and by using feedback from the senses.

24
Q

definition of reaction time

Study These Flashcards
A

the time taken between the onset of a stimulus and the start of movement in response

25
definition of movement time
the time taken from starting the movement to completing it
26
definition of response time
the time taken from the onset of the stimulus to the completion of the movement - reaction time + movement time
27
what are the two types of reaction time?
- simple reaction - choice reaction
28
what is a simple reaction?
When there is only one possible response e.g. a sprint start
29
what is a choice reaction?
when there are several alternative responses e.g. a cricket shot
30
what does Hick's Law suggest?
The more responses there are to a stimulus, the longer the response time (up to a certain point where it gets so slow that it cannot get any slower)
31
what is anticipation?
When a performer tries to pre-judge a stimulus
32
what is temporal anticipation?
Prediction of when a situation is going to happen
33
what is spatial anticipation?
Predicition of where and what is going to happen (pre-loading a skill)
34
why does Hick's law occur?
due to single-channel hypothesis which means that only one stimulus can be processed at a time and any second stimulus must wait for the first one to be processed. Therefore there is a delay in processing the second stimulus and response time increases
35
what is the psychological refractory period?
A delay when a second stimulus is presented before the first has been processed.
36
effect of correct anticipation on response time
it improves it as the information processing process is sped up because it can happen before the action has happened. Therefore the response can happen immediately
37
effect of incorrect anticipation on response time
will increase the response time due to the psychological refractory period and having to process the actual stimuli rather than the anticipated one.
38
How to improve response time?
- mental practice (especially in predictable environments) to improve anticipation - training to the specific stimulus expected in a game e.g. goalkeeper training to penalties taken to left if known that opposition usually goes left - improving fitness (through interval training etc) can improve movement time - performer could learn to focus and concentrate through making the stimulus more intense allows it to be picked up earlier
39
meaning of the parameters of a schema
four essential processes to ensure the schema used to adapt an existing motor programme is effective
40
when are recall schema used
before an action is initiated
41
what are the two recall schema?
1. initial conditions - 'Where am I, how am I?' -> where the person is, how their limbs are positioned, what is happening in their environment 2. response specifications - 'What do I need to do?' ->what needs to be done, how does the skill need to be adapted e.g. more power, what decision is recalled
42
when are the recognition schema used
during and after an action
43
what are the two recognition schema?
3. Sensory consequences -'how does it feel, do I need to adjust anything?' ->the feel of the decision, does it feel right e.g. the flight of the ball coming off the hands, can it be adjusted (yes for continuous skills) 4. Response outcome -'How did it go?' ->did the outcome match the intention?
44
how to promote adaption of schema and improve information processing?
- ensure the basic skill/programme is well learnt e.g. learning to throw before throwing a javelin - introduce variety of practice - give plenty of information and feedback - use strategies to motivate the player - point out transferable elements of learning the new task
45
how does ensuring the basic skill is well learnt promote adaption of schema and improve information processing?
it will increase the chance of an updated programme, through using the schema theory, being successful
46
how does variety of practice promote adaption of schema and improve information processing?
it will develop the player's ability to read their position and be able to adapt based on their environment (improving the link between initial conditions and response specification)
47
how does information and feedback promote adaption of schema and improve information processing?
allows the performer to link the response specification and sensory consequences, increasing their chance of being able to recall them in the future - ensures actions and motor programmes can be adjusted
48
how does motivation promote adaption of schema and improve information processing?
encourages the player to recognise that their actions are positive and should be repeated - will also encourage them to focus on creating the correct schema to suit the task
49
how does pointing out the transferable elements of learning the new task promote adaption of schema and improve information processing?
e.g. when adapting the overarm through to throwing a javelin, point out the weight transfer and release point - enables athlete to recognise some of the aspects of response specification and the sensory consequences, therefore increasing the chance of a successful action
50
when is the schema theory not possible?
a novice might not have developed a motor programme which can then be used to adapt and update information
