Information processing Flashcards
Sensory input (Definition:)
Refers to the information received from the surroundings.
Short-term sensory storage (Definition:)
The area of the brain which receives info and holds it for a short period of time prior to processing.
What happens to unimportant information in the short-term sensory store?
Information deemed unimportant is lost and replaced by new information.
Where is information initially ‘filtered’?
In the short-term memory store.
Selective attention (Definition:)
Process of sorting out relevant bits of information from the large amount received.
Short-term memory (Definition:)
The part of the brain which keeps information for a short period after it has been deemed worthy of attention.
How long is information held in the short term memory?
20-30 seconds.
What is the capacity of the short-term memory?
5-9 bits of information.
How can the capacity of the short-term memory be increased?
Chunking information together.
What happens to information in the short-term memory?
It is used for problem solving or transferred to the long-term memory for permanent storage.
T / F:
All information that is collected by the receptor system is transferred to the short-term memory where it is ‘filtered’.
False, the information is ‘filtered’ by the selective attention before it reaches the short-term memory.
What are the different stages in the information processing model?
Sensory input -> Short-term sensory store -> (Selective attention ->) Short-term memory -> Decsion making (or LTM) -> Motor output -> Feedback.
Long-term memory (Definition:)
The part of the brain which retains information for long periods of time.
How long is information held in the long-term memory?
Up to a lifetime.
What is the LTM and STM?
Long-term memory and Short-term memory.
