Infomation processing Flashcards
What is information processing
Process of taking account of the sporting environment and making decisions prior to the execution of the skill
What is the input stage
Performer picks up all the info from the display
What’s the display
everything that can be processed by the performer
What are the 5 senses used to collect information
Sight, Auditory, touch, balance, kinesthetics
What happens in the decision making stage
- makes a decision based on all the available info collected by the senses
- uses memory and selective attention
- use of perception
Selective attention
Filtering process that separates relevant info from non relevant info
Where does selective attention receive its info from
Short term sensory store and passes it to short term memory
Why is selective attention important
- helps keep info in stm for longer
- prevent information overload
How to improve short term memory
- increase intensity of the stimulus
- increase time to react
- analysis of strength and weaknesses
- increase fitness levels
- practice with distractions
- mental rehearsal
- make stimuli unique
- optimal arousal levels
Whitings model
- input from display
- receptor systems
- perceptual mechanisms
- translatory mechanisms
- effector mechanism
- muscular system
- output data
- feedback data
perceptual mechanism
process of coding and interpreting sensory information
what happens in the perceptual mechanism
- detection of stimuli
- comparison to memory stores
- recognition of stimuli
detection
performer has picked up the relevant information and identified what is important
comparison
trying to match info identified as important to info already in performers memory
recognition
performer has used the info from the memory to identify an appropriate response
translatory mechanism
- converts information so decisions can be made
- uses past experiences to link information and sends it to memory system
- actions stored in memory become motor programmed
effector mechanism
network of nerves that are responsible for delivering decisions made during the perceptual process to the muscles
how does the effector mechanism receive information
in the form of coded impulses and once the impulse is received the muscles contract and response can begin
feedback
info used during or before the response to aid movement correction
Bradley and hitch working memory model
- display
- phonological loop
- central executive
- episodic buffer
- visuospatial sketchpad
- long term memory
central executive
overall control of the working memory
identifies which info needs to be sent to each one of its subgroups
phonological loop
works with auditory info from the senses and helps produce a memory trace
visuospatial sketchpad
- concerns visual and spatial info and temporarily stores this information
- helps process info about the feel of a movement
episodic buffer
- coordinates work of phonological loop and visuospatial sketchpad into sequences to be sent to the long term memory
- starting point for the initiation of motor programmes
working memory
