Atkinson And Shiffrin (Multi-store Model Of Memory) Flashcards
3 distinctly different stores
Sensory register( a sensory memory)
Short-term memory
Long-term memory
Sensory register and the role of attention
- We register alot of information briefly but we don’t pay attention to all of it
- sensory register is store that receives all of sensory information and is transferred into our short-term memory where we process it further
- if not payed attention to it gets lost
- beloved we have separate sensory register for each of our principle senses
Ionic memory
Echoic memory
The gustatory (taste) sensory register
The olfactory (smell)sensory register
The tactile(touch) sensory register
Iconic memory
The sensory register for visual information that lasts for around 1 second before visual information decay’s
Echoic memory
The sensory register for auditory (sound) information that lasts a yew seconds before sound information decays
Short-term memory: capacity and duration
- STM stored 15 - 30Sec ( Atkinson andshiffren)
- they describe STM as modality free
- STM can hold between 5-7 types of information
The role of rehearsal
- Repeating information over and over again helps hold it in short term memory for longer
- if rehearsed long enough it gets transgress into the long-term memory
Long-term memory: capacity and duration
- Hold information indefinitely and it has potentially limitless capacity
- organised semantically
Strength of the theory
- A lot of evidence to support the theory of separate memory stores( cases of amnesia show how brain injury can damage long term memory while short term memory remains)
Weaknesses of theory
- Has been critizized for overstating role of rehearsal
- unlikely that we have only one type of long term memory
Primacy
Tendency to recall words at beginning of a list when asked to remember it
Recency
The tendency to recall words at the end of a list when asked to remember it
