Memory and information processing Flashcards
(19 cards)
what is information processing ?
method by which data from the environment is collected and utilised.
name the 4 stages of information processing
1) Input stage
2) Decision making stage
3) Output
4) Feedback
What happens during the input stage
performer uses senses to pick up information about the display.
Name two external senses
1) sight
2) auditory
Name three internal senses
1) touch
2) balance
3) kinesthesis
What happens in the decision making stage ?
Performer uses selective attention to make a decision
What is selective attention ?
The filtering of relevent information from irrelevent information.
How can selective attention be improved ?
- Mental practice
- Motivation + rewards
- Learn to focus on rellevant stimuli
- Improve fittness
Benefits of improving selective attention
- improves reaction time
- improves decision making
What does the perceptual mechanism do ?
It starts a process of coding and interpreting sensory information.
What are the three stages of perception ?
- detection - eveluate display
- comparision - compare to the long term memory
- recognition - choose the appropriate response
What happens at the translatory mechanism ?
addapting and comparing coded information to the memory so decisions can be made.
What does the translatory mechanism do ?
compares current information, to similar information stored in the memory to understand what decision to make.
past actions are stored in the memory as……
Motor programmes
translatory mechanism uses …….
coded information from the perceptual process to pick out an appropriate motor program
What happens at the output stage ?
skill is executed
What is the effector mechanism
network of nerves that sends coded impulses to the muscles.
What happens at the feedback stage ?
Information recived / interpreted durning or after the skill, to aid movement correction for next time the skill is performed.
Information processing step by step.
1) input data from display
2) Receptor systems
3) perceptual mechanism
4) translatory mechanism
5) effector mechanism
6) muscular system
7) output data
8) feedback data
