Memory Models Flashcards
What is the general information processing model?
Input–>Decision making
–>Output–>Feedback
What is the input stage?
During this stage the performer uses the senses to pick up information from the sporting environment.
What is the display?
The sporting environment, which can include the crown, movement from the opposition or the conditions.
What 5 senses is the receptor system made up of?
Give an example of how they could be used for each.
-Sight (or vision)- For example a footballer seeing the flight of the ball allowing them to prepare to make the correct touch.
-Auditory sense (hearing)- A player may hear the call of a teammate meaning they can make a pass without having to look up.
-Touch- A cricket batter may be able to feel the grip of the bad allowing them to know if they are holding it right.
-Kinesthesis- a swimmer may use it to help them be aware of body position during a tumble turn.
-Balance- a basketball player needs to be balanced to ensure the accuracy of a shot.
What do proprioceptors do in relation to input?
They give information about internal senses such as touch, kinesthesis and balance.
Define selective attention and give a sporting example.
Filtering relevant information from irrelevant information. For example a badminton player only paying attention to the positioning of the opponent and the flight of the shuttlecock, rather than the crowd noise or the advertisement.
How can a performer develop their selective attention?
-Experience
-By making the stimulus brighter or louder in training
-Training with distractions in a realistic environment to ensure they are used to ignoring them.
-Improved motivation by using rewards and praise
What are the benefits of selective attention?
-Improves reaction time
-Improves chances of making a correct decision
-Prevents cognitive overload.
Explain Atkinson’s and Shiffrin’s multi store memory model
-Sensory memory is brief, lasting less than a second, and enables the individual to process initial information from the environment.
-Short-term memory, also known as working memory, lasts for about 20-30 seconds and can hold 5-9 chunks of information.
-Long-term memory is theoretically infinite in capacity and duration, storing information for extended periods of time.
-Information can only move from sensory to short-term and then to long-term memory when attention and rehearsal are applied.
What is DCR?
The perceptual stage of information processing involves three aspects of activity:
-Detection- the performer picks up the relevant information and identified it as important, using senses and selective attention.
-Comparison- Involves trying to match the information identified to the information already in the memory of the performer.
-Recognition- the performer causes the information from the memory to identify an appropriate response
Define perception
The process of coding and interpreting sensory information.
What are Translatory Mechanisms?
Adapting and comparing coded information to memory so that decisions can be made. Uses coded information from the perceptual process to pick out an appropriate motor program.
What is the Effector mechanism?
The network of nerves that sends coded impulses to the muscles. The muscles receive the coded impulses then the muscles will contract and the response can begin.
Explain Whiting’s information processing model.
Input data–>Receptor systems–>Perceptual mechanisms–>Translatory Mechanisms–>Effector Mechanisms–>Muscular system–> Feedback data
What is the working memory?
And name the three sub systems.
The working memory consists of a central control centre, known as the central executive which uses three other systems to control all the information moving in and out of the memory system.
-Phonological loop
-Visuospatial sketchpad
-Eposodic buffer
What is the phonological loop?
Deals with auditory information from the senses and helps to produce the memory trace. The memory trace is an initial mental idea of the skill, it can be sent to the long term memory where it can trigger a motor program.
What is the Visuospatial sketchpad?
Used to temporarily store spatial and visual information and help to process information about the feel of a movement. It is further divided into two sections; the visual cache which holds information about form and color and the inner scribe which deals with spatial and movement information.
What is the Eposodic buffer?
Coordinates the sight, auditory and movement information from the working memory into sequences to be sent to the long term memory.
What is the long term memory in relation to the working memory system?
Receives information from the working memory and has an unlimited capacity for storage of motor programmes.
Give three characteristics of the memory system.
-Initiates the action by by sending the memory trace
-Has a limited capacity as it can only deal with around seven items of information at any one time. Too much information could mean that important information is lost.
-Has a limited time scale- lasts for around 30 seconds.
-Important information can be stored in the Long Term memory in the form of a motor programme.
-Long term memory has a large capacity and can store information for a lifetime if needed.
