Unit 3: Neurobiology and immunology - Memory Flashcards
What does memory involve?
Memory involves encoding, storage and retrieval of information.
What must happen to sensory image first, to become part of the memory?
Encoded.
What does encoded mean?
Converted to a form that the brain can process and store.
What is storage?
The retention of information over a long period of time, can be 30seconds or a lifetime.
What is retrieval?
The recovery of stored material, involves the recall of information from the short or long- term memory.
What does all information entering the brain pass through first?
The sensory memory.
Where does information in the brain go after being passed through the sensory memory?
The short term memory/STM
Where does information in the brain go after entering the STM?
Information is then transferred to long- term memory/LTM or is discarded.
What part of the memory is very short lived only lasting around 0.5s?
The sensory memory.
What part of the memory can hold about 7 items of info for around 30seconds?
Short- term memory.
What part of the memory has an unlimited amount of information stored for up to a lifetime?
Long- term memory.
Does the STM have a limited or unlimited capacity?
Limited.
How many items can the STM store at one time?
Around 7 items.
How long is info stored in the STM?
30seconds.
After 30 seconds what happens to info in the STM?
The information is either transferred to the LTM or is lost by displacement or decay.
