Cognition 2017 Flashcards
What are 3 systems of memory?
- sensory memory
- short term memory
- Long term memory
Who suggested the Information Processing Model ?
Atkinson and Shiffrin (1968)
What do Atkinson and Shiffrin suggest about IPM?
- that memory is made up of a series of stores
- Explains how processes such as sensation, perception, attention and memory are controlled
4 stores of memory
- mental representation
- encoding
- storage
- retrieval
Function of sensory memory
stores all incoming sensory information
Duration of sensory memory
Memory retained for a short period of time (5 seconds)
iconic
echoic
what is iconic
temporarily stores information of visual nature (eyes)
what is echoic
temporarily stores information for auditory nature
function of STM
working memory (thoughts, words and images are available for decision making and problem solving)
Duration of STM
stores for around 30 seconds
Capacity of STM
(George Miller) (7+ - 2) (5 - 9)
What does STM allow us to do?
Rehearsing information allows us to transfer material to LTM
3 types of STM
maintenance
elaborative rehearsal
chunking
What is maintenance rehearsal
Meaningless rote repetition of material to be remembered (least effective)
what is elaborative rehearsal
applying meaning to new words in order to retain in memory (most effective)
what is chunking
Material is combined into large, meaningful groups
Who came up with working memory model?
Baddley & Hitch 1914
3 sections to working memory model
- central executive
- visual spatial sketchpad
- phonological loop
What is central executive
- boss of working memory
- controls & coordinates other components
- controls attention, sending incoming information to the relevant comment and briefly stores all sensory information.
What is visual spatial sketchpad
Stores and manipulates information of a visual and spatial nature; a slave system to the central executive
what is phonological loop
The other slave system; also known was the rehearsal loop; stores and manipulates information of an auditory nature
what was the fourth section Baddley added?
episodic buffer
What is an episodic buffer
- Episodic buffer links information across all domains to form integrated units of visual, spatial and verbal information with time
- Provides link to LTM
What is LTM
- A relatively permanent storage facility for an intimate amount to information
Procedural
Declarative
