lesson 3 & 4: multi store model of memory and type of LTM encodes Flashcards
The Multi-Store Model of Memory, 1968
DESCRIPTION
Atkinson and Shiffren suggest memory made of series of stores, describes memory as information flowing through a linear system
described as an information processing model, like a computer with an input, process, output
The Multi-Store Model of Memory, 1968
definition of maintence rehearsal
repetition to help hold something in STM, will eventually transfers to LTM
definition of elaborative rehersal
includes more meaningful analysis eg images, thinking, association, leads to better recall, like giving words meaning or linking to previous knowledge
Sperling, sensory memory for vision, 1960
AIM AND FINDINGS
aim: study the sensory memory for visoin using the iconic store
uses tachistoscope, device flashes picture stimulus
asks Pp remember as many letters as possible from 12 symbol grid, displayed for 50ms
could only recall around 4 symbols before grid faded from sensory memory
reported seeing a lot more they had time to report
Sperling, sensory memory for vision, 1960
CAPACTIY
changed his technique used the Partical report technique
trained Pp to distinguish between 3 tones, high, medium, low
exposed grid for 50ms
when disappearded 1 of the tones followed, disapearing from a high to low tone
with partial report condition recall was 3/4 symbols from each row
iconic store retain 76% of all data
Sperling, sensory memory for vision, 1960
DURATION
if there was a delay between presenting grid and surrounding tone more information was lost
only 50% after 0.3 second delay
only 33% after 1 second delay
Glanzer & Cunitz, 1966
research to support,
Pp presented with word list and immediately recall them
words at the beginning are recalled= primary effect
words at the end are recalled= recency effect
words in the middle are forgotten= asymptote
The multi-store model of memory
EVALUATION
+ shows differences between STM and LTM. STM different in capacity, duration, encoding
Miller, suggests STM capacity 7+-2 chunks vs LTM is unlimited
empirical support for MSM= wider academic credibility
- too simple, other models suggest STM and LTM can be divided into more stores
working memory model, STM represented by series of seperate stores that handle different modalities
Tulving= divided into episodic, semanitc, procedural
MSM isn’t complete explanation of the structure of memory
