What is information processing?
- methods by which informstion from the environment is collected and utilised
- process of taking into account the sporting environemtn and making decisions prior to executing skill
What are the 3 stages to information processing?
1) Input
2) Decision making
3) Output
Define the ‘input stage’ of information processing
information is picked up from the dispaly by your senses (know as your receptor systems)
What are the 5 senses, and give sporting example with each
1) Sight = perfromer picks up display with vision
e.g position of opponent/flight of ball/angle of goal
2) Auditory senses = information collected by hearing
e.g call of teammate/sound of ball on a bat
3) Touch = touch used to aid performance
e.g grip of ball
4) Balance = aids in proper execution
e.g gymnast in a beam routine
5) Kinethesis = inner sense providing information about body position and msucular tension
e.g swimmer during a tumble turn
What are the internal and external senses?
Internal = touch, balance & kinethesis
- proprioreceptors provide intrinsic informtion about the body
External = sight and hearing
What is the ‘decision making’ stage of information processing?
= decision is based on all the information collected by the senses
in order to to make decisons, selective attention and th ememory system are vital
What are the 3 areas of decision making?
1) selective attention
2) perception
3) translatory mechanisms
Define selective attention
= filtering relevnat information from the irrelevant information
e.g must focus on position of ball/opponents/teammates, but disrgard the crowd
How can you develop selective attention?
- experience of both the performers and coaches
- learning to focus/concerntrate
- getting used to a stimulus. Louder/brighter/more intense stimuli will dvelop concerntrtaion.
- Improving motivation with rewards/praise. Performer becomes more alart to important information if praised for correct decisions.
- Application of mental practice allows performer to run through the task in mind before the movemnt actually starts.
What are the benefits of selective atention?
- improves reaction time
- improves chances of making the correct decisions
- able to concerntrate on the more detailed aspects of a task
- limits the amount of info noted at one time, which benefits the working memory as it has limited capacity. Too much info = affetcs memory function
- not disctarcted by irrelevant informstion in the envrionment
What is ‘perception’?
= the process of coding and interpreting sensory information
DCR
DCR?
Detection
= performer has picked up infromation and regocnised it as important
- uses the senses and information processing
Comparion
= trying to match the identified as improtant information to infroamtion already in the memory of the performer.
Recognition
= perofrmer has used the info from the memory to identify an appropiate response
- the repsonse is then put into action
-
What makes infromation hard to detect?
- unclear info
- too much info at once
- disguised by opposition
What are ‘translatory mechanisms’?
= adapting/convtering/comparing coded information so that decisions can be made
- uses past experiences
How do translatory mechaisms work?
1) Informtion from senses is filtered
2) Info is adapted anf sent to the memory for comparison
3) past experiences are linked to the informaton sent to the memeory system
4) similar actions stored in the memory can be recognised and then used
= uses coded inforamtion from the perceptual prcoessto pick out an approtpirate motor programme
Where are translatory mehcnaisms most effective
In ecperiecend performers
- already have infromation in the memory to aid this process.
Define the ‘output’ stage of informaion processing
= last phase of information processing before the response begins
What is the ‘effector mechanism’?
= the network of nerves that sends coded impulses to the muscles
Effector mechnaism and musuclar output?
- Muslces will recieve imformation, in the form of coded impulses (sent by the effector mechanism)
- When the impulse is recieved, muslces begin to contract and the reposne begins
‘Feedabck’ phase of output?
feedback = information used during/after the response to aid movemnt correction
What is the order of information processing & explain what happens in each step.
1) The environment – contains the display
2) Display – all the sensory inforamtion availible to the player
3) Receptor systems – the 5 senses collect information from the display
4) Perceptual mechanisms – selective attention (filter the information picked up by senses). DCR
5) Transaltory mechanisms – info is compared to information already stored in the memory
6) Effector mechanisms – coded nerve impulses sent to the muscles, via the CNS
7) Muscles – recieve impulse, and begin contraction
8) Output – response begins
9) Feedback – feedback given during/after the reponse. Intrinsic & extrinsic
What is the order of information processing?
1) Environment
2) Display
3) Receptor systems/sensory organs
4) Perceptual mechanisms
5) Translatory mechanisms
6) Effector mechanisms
7) Muscles
8) Output
9) Feedback

The memory system & information processing
all information picked up by the senses is stored in the memory
What is the ‘working memory’?
= performs a number of functions
- consists of a central control centre (central executive)
What is the ‘central executive’?
= control centre of the workign memory model
- uses 3 other ‘sub systems’ to control all infromation moving in and out of the memory system
What are the 3 sub systems of the central executive?
1) Phenological loop
2) Visuospatial sketchpad
3) Episodic buffer
Describe the ‘phenological loop’
(PL)
= deals with auditory information from the senses and helps produce the memory trace
What is a memory trace?
= initial mental idea of the skill, whcih can be sent to the long term memory where it can trigger a motor programme
WHat is a motor programme?
= permenant trace stored in the LTM, that contains all the components taht make up a skill
Describe the ‘visuospatial sketchpad’
(VS)
= used to temporarily store visual and spatial information
Divided into 2 areas
- visual cahce: info about form & colour
- inner scribe: spatial & movement info
Describe the ‘episodic buffer’
(EB)
= co-ordinates the sight, hearing and movement infromation from the wokring memory into sequences to be sent to the long-term memory
- coridnates the work of phenological loop and visuospatial sketpad to create a sequence which is sent to the long-term memory
- starting point for a motor programme, and can be used to create movment
Summerise the 3 subsystems of the working memory
Phenological loop = auditory information creates memory trace
Visuospatial sketpatch = temporarily stores visual & patial inforamtion
Episodic buffer = PL + VS = sequence which is sent to the long term memory
Is working memory long or short term?
Short term and temporary
- central executive/phenological loop/visuospatial sketchpad/episodic buffer
Define ‘long term memory’
(LTM)
= recieves information from the working memory, and has unlimited capacity for the storage of motor promgrammes
Describe the process of memory
1) Working memory picks up informtion from the display
2) Selective attention filters out irrelavent information
3) PL and VS produce a memory trace (hearing, sight and spatial info)
4) Memory trace is sent to the LTM
5) LTM compares this memory trace to info already stored within the LTM
6) LTM sends info back to the working memory for use in current sporting action
Summerise working memory and LTM
- working memory sends coded for information to the LTM
- LTM comapares this for future storage/use/decision making
- Work together in a 2 way process.
Features & functions of the working memory
- initiates actions by sending the memory trace
- limited capacity (5-9 items at one time. Too much = overload and important info could be lost)
- Limited time scale (30 seconds until info is used or lost)
Features & functions of the LTM
- info stored aas motor programmes (=permenant trace of skill consisting of all the components that make up thta skill)
- Large capacity
- Lasts forever
