Information processing Flashcards
What are the 4 stages of the general information processing model?
- Input
- Decision making
- Output
- Feedback
Describe the input stage in a general information processing model
- receptors use senses to take in information from the display
- selective attention is used
what is selective attention and how does it benefit the performer?
- 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
methods of improving selective attention
- 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
Describe the decision-making stage in a general information processing model
- 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
Describe output stage of basic information processing model.
- sending of nervous impulses to muscles to carry out the chosen response
what do the perceptual mechanisms do in Whiting’s information processing model?
Person perceives what the most important sense is and SELECTIVELY ATTENDS to it
describe the translatory mechanisms in Whiting’s information processing model
- performer translates the information they have attended to into a decision (decision-making stage)
Describe the effector mechanisms in Whiting’s information processing model
- send the decision to the muscular system via the nervous system
describe the muscular system of Whiting’s information processing model
the appropriate muscles receive the signals to carry out the response
what is the output data on Whiting’s information processing model?
The action is carried out and feedback is received both extrinsically and intrinsically
What are the components of the Baddeley and Hitch working memory model
- sensory receptors
- central executive
- phonological loop
- visuospatial sketchpad
- episodic buffer
- long term memory
what does the central executive do?
- selective attention
- monitors and coordinates the operation of the visuo-spatial sketchpad and the phonological loop
what does the visuo-spatial sketchpad do?
- the inner eye
- processes visual/spatial/kinesthesis info
- used for navigation
- may be responsible for recalling, displaying and manipulating set plays and positions on the field
what does the phonological loop do?
deals with spoken and written information
what is the phonological store (PS)?
- holds information in speech form
- inner ear
- spoken words enter the store directly whereas written words must be converted into spoken form first
what is the articulatory control process (ACP)?
- inner voice
- circulates information round and round e.g. remembering a phone number
what is the episodic buffer?
- 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
what are strategies for improving information retention (in the LTM)?
- 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
features of the working memory
- 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
