Information Processing Model And DCR Process Flashcards
What order does the info processing go (whitings)
Display- receptor system- perceptual mechanism - translatory mechanism- effector mechanism -muscular system- output data- feedback data
What is the display
All of the sensory info surrounding a performer, the environment
What is the receptor system
The 3 senses, auditory, visiual and touch. Touch split into kinasthesis, equilibrium and proprioreception
Selective attention- ability to attend to the relevant information and disregard the irrelevant information
What is the perceptual information
The interpretation of information
Selective attention filters the in and out
DCR process starts
Wrong selective attention- lead to confusion, lack of fluency, could lead to a congnative overload
Right selective attention- depiction making consistent, relevant info, accurate
What’s the translatory mechanism
Decisions are converted into commands for the effector mechanism
Makes sense of whats happening
The LTM and STM are used
What’s the effector mechanism
Output
Neural stimulation via CNS
What’s muscular system
The muscle contractions, and use of timings
What does DCR stand for
Detection, comparison, recognition
What is detection in the DCR process
Utilises memory systems, starts in the STM.
You interpret the relevant information, information we do not attend to will leave our system
You have picked up the information that is important or relevant to you in that moment and disregarded irrelevant info.
You do this through selective attention
What is comparison in the DCR process]
Uses the translatory mechanism
Looking for the correct MP to use
Compares the STM with similar experiences stored in LTM. Stored as motor programmes and schemas
Memory trace gets sent to the LTM to look for the comparison.
What is recognition in the DCR process
Decscison sent to effector Mechanism, the MP can be put into affect
The performer as used info from memory systems to identify an appropriate response
Occurs when the incoming memory trace matches a stored movement or experience in LTM.
When does the response time start and finish in the processing model (give definition)
It is from the onset of the stimulus (display) to the completion of the skill (feedback)
When does reaction time happen in the processing model (definition)
From the onset of the stimulus to the start of the movement (effector mechanism)
This phase is all psychological
When does movemnt time happen in the info processing model
Starts from the onset of the movement (effector m) to the completion of the skill (feedback)
What is the equation for response, reaction and movement time
Response T= rea T+ MT
(Reaction T could be the start of a horn, gun of 100M sprint)
What is the copacity and duration for the short term memory
Copacity: the usual amount of info is 7+ or - 2 items (5-9 items)
Duration: 30s
What is the duration and copacity for LTM
Duration: forever as long as it is practiced and repeated on a regular basis, if it is not used it will be forgotten and have to be relearnt
Copacity: unlimited
