Information processing Flashcards
State the four main stages of information processing
Input, descion making, output, feedback
Describe the input stage
INPUT – information is gathered from the environment/display by the senses. The performer uses their perception to interpret the information and judge which cues are required. The cues are filtered into relevant and irrelevant information by the process know as selective attention.
What is reaction time
The time between the presentation of a stimulus and the start of a response
What is response time
The reaction time plus the movement time
What is movement time
The time take to complete a movement after it has been started
What is the single channel hypothesis
States that each stimulus can only be processed one at a time and therefore a second stimulus must wait until the first has been processed. This is known as the psychological refractory period
Describe the output stage
The skill is produced
Describe the descion making stage
The memory system is engaged and previous experiences are reflected upon. The relevant motor programme is sent to the muscles in reediness to produce a skill.
Describe the feedback stage
Information is gathered during and after the performer.
Stages of whiting’s model of information processing (in depth)
Sensory information from display, receptor system, body boundary, perceptual, filtering, translatory, effector , movement

Steps in Whiting’s model of processing
Stimulus identification, Response Identification, Response Programming
What happens during stimulus identification of Whiting’s model
Display is collected using perceptual mechanism, filtered through selective attention. It will gather:
- Speed/direction
- Location of team mates
- Location of opponents
- Personal location
- Strategies being adapted
- Shouts from spectators
What happens during response identification of Whiting’s model
Relevant information is assessed against previous experience and stored in the memory
What happens during response programming of Whiting’s model
Motor programme completed effector mechanism
What are the four main components of Baddeley and Hitch’s working memory model
- Central Executive
- Visuo-spatial sketchpad
- Phonological loop
- Episodic buffer
