Memory - Paper 1 Flashcards
What is coding?
The format in which information is stored in the various memory stores.
What is capacity?
The amount of info that can be held in a memory store at a given time
What is duration?
The lengths of time info can be held in a memory store.
What is the multi-store model of memory?
Developed by Atkinson and Shiffrin (1968)
Model representation of how memory works using 3 stores- sensory register, long-term memory and short-term memory
What is the sensory register? (SR)
Info from our senses stored here
Includes any stimulus from environment eg. sounds, sights and smells
2 main stores are echoic and iconic memory
Echoic is auditory so info coded acoustically
Iconic is visual info so oded visually
Has a high capacity
Not all info goes through to stm, if you pay attention to it then it will pass through
Duration less than 1/2 second
What is short term memory?
The limited capacity memory store 18
Coding mainly acoustic
Capacity between 5-9 items on average
Duration is between 18 and 30 seconds
Maintenance rehersal helps retain info in STM
Prolonged maintenance rehersal allows info to pass to LTM
What is long term memory?
Potentially permanent memory store for info that has been rehersed
Unlimited capacity and duration
Can store memories for up to a lifetime
Coding mainly semantic
Use retrieval to recall memory back from LTM to STM
Anything lasting longer than 30 seconds
Implicit- cannot be consciously recalled
Explicit-can be inspected and consciously recalled
Tulving criticised MSM for being too simplistic, proposed idea of 3 types of LTM
What does the multi-story memory model look like?
What is episodic memory?
Any events that can be reported from a person’s life, a “diary” of memories
Very complex and time-stamped (know when it happened/ when it was made)
It is explicit
Eg- cinema trips, favourite christmas
What is semantic memory?
Conscious recall of facts that have meaning as opposed to our own life events.
Stores knowledge of world
It is explicit
Eg- types of animals, capital cities, meanings of words.
What is procedural memory?
Implicit knowledge of tasks that usually don’t require conscious recall to perform them
For actions and skills and now we do them
Eg-walking, talking
What is the working memory model?
A representation of STM that suggests STM is a dynamic processor of different types of info using sub-units coordinated by a central decision-making system
Which model is the working memory model trying to improve ?
Developed by Baddeley and Hitch (1974)
Focuses specifically on workings of STM
Developed in response to criticism of multi store model of memory which was over-simplified
WMM composed of 4 main components, each have different coding and capacities.
What is the central executive?
Manages attention and controls info to and from 3 “slave stores”
Processes info in all sensory forms but only able to deal with one strand of info at a time
Very limited capacity
Also deals with cognitive tastes- arithmetic and problem solving
What is the phonological loop?
One of the slave systems
Deals with auditory info, coding is acoustic
Preserves info in order which it arrives
Capacity is 2 seconds worth of what you can say
