Information processing Flashcards
Define effector
Impulses sent from brain to working muscles
Define memory
The storage, recognition and transfer of information between memory stores
Define feedback
Information after the response, to aid movement correction
Define display
The sporting environment contains information to be collected by the senses
Define muscles
Muscular contractions during movement
Define response
Action to the display
Define senses
Five senses used to pick up information from the display - hearing, vision, touch, equilibrium and kinesthesis
Define DCR
Detection, Comparison, Recognition
Define selective attention. Why is it important?
The filtering of relevant stimulus from irrelevant noise.
Important as it avoids information overload and allows the performer to focus on the important cues
What do translatory mechanisms do?
Compare and adapt
Define environment
Surroundings from which information is collected
Define receptor systems
Sense organs receive information from display
Define central executive
Perceives surroundings
What does the episodic buffer do?
Coordinate information into sequences to link to the LTM
What sequence does information processing follow?
- Environment
- Display
- Senses
- Selective attention
- DCR
- Translatory mechanisms
- Memory
- Effector
- Muscles
- Response
- Feedback
Define reaction time
Onset of stimulus to onset of movement
Define movement time
Start of completion of task
Define response time
Onset of stimulus to completion of task
Response time = Reaction time + Movement time
What is Hick’s law?
More choices means a slower reaction time
What is the single channel hypothesis?
States that only one stimulus can be processed at once
What is the psychological refractory period?
A second stimulus presented before the first has been processed causes a delay
What methods can be used to improve reaction time?
Practice to stimulus
Anticipate
Make stimulus intense
Concentrate
Get fitter
Train with relevant distractions
Define anticipation. What are the two types?
Pre-judging a stimulus
Spatial (where)
Temporal (when)
What is simple reaction choice?
When there is one response to one stimulus (should produce fast reaction)
What is choice reaction time?
When there are multiple reactions due to a number of stimulus (produce a slow response)
