Information processing Flashcards
What is information processing?
The process of taking account of the sporting environment and then making decisions prior to the execution of the skill.
Input - decision making - output.
What is the input stage?
The performer uses the senses to pick up information from the sporting environment - the display.
What is sight?
The performer can pick up the flight of the ball or the position of an opponent using their sight.
Picking up such information early can be useful and may mean that the information on the flight of the ball is processed quickly, allowing the performer a fraction of a second more to make the decision.
What is auditory sense?
A player may hear the call of a teammate or the sound of the referee’s whistle.
A cricketer may hear the sound of the ball catching the edge of the bat before attempting to make a catch.
What are the proprioceptors?
The internal senses are called proprioceptors, which provide intrinsic information about touch, balance and kinesthesis.
Hearing and sight are external senses.
What is touch and balance?
It can be used to feel the grip on the ball or the feel of the springboard used by a diver through their feet.
The basketball player who needs to set their feet before taking a free throw needs to be balanced to ensure the accuracy of the shot.
What is kinesthesis?
A sense from within the performer, using sensors within the muscle receptors that relay information about muscle tension and therefore body position.
The swimmer will use kinesthesis to help them be aware of body position during a tumble turn.
What is decision making?
The performer must make decisions based on all the information collected from the senses.
Selective attention and the memory system are very important here.
What is selective attention?
The process of filtering the relevant information from the irrelevant information.
For example, the ball and position of opponents in a game might be information that is vital but the crowd might be something the performer wants to ignore.
How can selective attention be developed?
Learning to focus and concentrate on the important information, getting used to the stimulus.
If the stimulus is made more intense, loud or bright when the performer is training, it helps to develop concentration.
For example, a football player may use a brightly coloured ball during training.
How can selective attention be developed - ignoring?
The performer may also learn to ignore the irrelevant information by training with distractions in a realistic environment.
Sounds associated with a passionate crowd, as well as the national anthem, could be played over the loud speaker during training, in anticipation of the atmosphere expected at the game.
The players are told to concentrate on their calls and communication and to ignore the crowd noise.
How can selective attention be developed - motivation?
Improved motivation helps selective attention.
Coach and player could enhance motivation by using rewards such as positive comments, and once motivation is increased, the performer becomes more alert to the important information.
The application of mental practice can help the process when the performer runs through the upcoming task in the mind before the movement starts.
What is DCR?
The perceptual stage of information processing involves detection, comparison and recognition.
Detection means that the performer has picked up the relevant information and identified it as important, using the senses and selective attention.
Comparison involves trying to match the important information to information already in the memory of the performer.
Recognition means that the performer has used information from the memory to identify an appropriate response, to then be put into action.
What is the translatory mechanism?
Helps to adapt and compare (convert) coded information to memory so that decisions can be made.
The filtered information from the senses is adapted into an image that can be sent to the memory for comparison.
The translatory mechanism uses past experiences so that information received can be linked with these past experiences and sent to the memory system.
Similar actions which have been stored can be recognised and then used.
Actions are stored in the memory in the form of motor programmes.
The translatory mechanism uses coded information from the perceptual process to pick out an appropriate motor programme.
What is the translatory mechanism?
Using the information from the perceptual mechanisms, a decision is made on what action should be taken, with the help of previous experiences stored in the memory.
The correct response is selected in the form of a motor programme.
What is the effector mechanism?
It is the network of nerves that is responsible for delivering the decisions made during the perceptual process to the muscles so that those muscles can perform the action.
The muscles will receive the information in the form of coded impulses and once this impulse is received, then the muscles will contract and the response (output) can begin.
What is feedback?
Information used during or after the response to aid the correct movement.
Positive, negative, internal, external, knowledge of results, of performance.
What is the central executive?
It has overall control over all the information entering and leaving the working memory.
It quickly identifies which information should be sent to one of its sub-memory systems.
These sub-systems perform different functions: phonological loop, visuospatial sketchpad, episodic buffer.
What is the phonological loop?
In sport, auditory information can be processed here.
It is a temporary storage system, which creates a memory trace that is sent to the long term memory to trigger the motor programme.
The memory trace fades away if not rehearsed.
What is the visuospatial sketchpad?
It holds visual and spatial information.
It also helps to process information about the feel of the movement such as the flight of a gymnast during a vault.
The spatial component suggests information about sporting actions that can be recognised and acted upon.
What is the episodic buffer?
This co-ordinates the work of the phonological loop and visuospatial sketchpad into sequences.
It produces integrated sequences of sight, sound and movements which can be sent to the long term memory.
They are the starting point for the initiation of motor programmes, which are patterns of the whole skill, and can be used to produce movement.
What does the working memory do?
Selective attention is used to filter out irrelevant information.
The working memory has links with the long term memory, sending coded information for future storage and use.
