Paper 1: Memory Flashcards
What’s the difference between the Working Memory Model and the Multi-store memory model?
The multi-store model is the whole explanation of the system of memory. The Working Memory Model is the detailed evolution of the STM section of the multi-store model.
Who devised the multi-store model?
Atkinson and Shiffrin (1968)
Who created the Working memory Model?
Baddeley and Hitch (1974)
What are the 3 stages of the multi-store model?
Sensory Register, Short Term memory and Long Term Memory.
How is memory transferred from one store to another?
Sensory Register is transferred to STM through attention. STM is reinforced through rehearsal and is brought from LTM through retrieval. STM is transferred to LTM through transfer.
What are the two stores in the Sensory Register?
The iconic and echoic store.
What is the capacity and duration of the Sensory Register?
Almost unlimited capacity because it requires the use of all the senses however the duration is very short eg 500 milliseconds to 2 seconds.
What is encoding in the terms of SR to STM?
Raw information is changed to something digestible, either visually (an image of ice-cream), acoustically (the word ice-cream) or semantically (the concept of an ice-cream).
Who tested the capacity of the STM?
Jacobs (1887), 7 chunks and 9 numbers.
What is the duration of the STM?
30 second.
What are the duration and capacity of the LTM?
Anything longer than 30 seconds and unlimited capacity.
What evidence supports the multi-store model?
Duration of Long Term Memory- Bahrick et al (1975) could remember 80% of friends 48 years later.
Existence of separate stores shown by Glazner and Cunitz (1966)
What are the weaknesses of the multi-store model?
Both STM and LTM are overly simplistic as compared to the working memory model.
What are the 4 separate components of the WWM?
The Central Executive connects the phonological loop, episodic buffer and visuo-spatial sketchpad.
Who found the capacity of the central executive?
Baddeley (1996) found the central executive struggled to perform two STM tasks simultaneously.
What are the two sub-stores below the Phonological loop?
The Phonological store and articulatory loop.
