memory revision Flashcards
what are the three memory processes
encoding, storage and retrieval
what is encoding?
transforming information into a format where it can be stored in memory
what is storage?
retaining information in memory so it can be used later
what is retrieval?
recovering information in memory so we are consciously aware of it.
which memory model are Atkinson and Shiffrin (1971) responsible for?
the multi-store model
what is the sensory store in the multi-store model and what are the two types of information it takes in?
it is a store of sensory information. iconic memory is for visual information and the echoic is for auditory information.
what did Miller (1956) find the capacity for short term memory?
approximately 7
what is the duration for STM and LTM?
LTM is long and STM is short
what is the capacity for STM and LTM
LTM is unlimited and STM is limited
what are the two types of forgetting for STM
Trace decay and interference
what is trace decay?
each item leaves a trace that decays over time until it is no longer available to us.
what is interference?
as we store so much information it is likely we can end up with the wrong memory.
what are the two levels of processing by Craik and Lockhart (1972)
shallow/physical and deep/semantic
which level of processing produces elaborate, long lasting and strong memory’s
deep/semantic
what memory model was made by baddely and Hitch (1974)
the working memory model
what is the purpose of the central executive?
it drives the whole system and allocates data to the subsystems.
what are the two components of the phonological loop?
phonological store (concerned with speech perception) and the articulatory control processes (concerned with speech production)
what is the phonological similarity effect (Conrad, 1964)?
Recall is 25% worse with a phonologically similar list compared with dissimilar list. this suggests speech based rehearsal processes within the phonological loop.
what is the word length effect in the phonological loop?
memory span is less for words that take a long time to say.
what is sensation?
the physical stimulation of the sensory apparatus
what is perception?
the ability of the mind to refer sensory information to an external object and its cause
what is the primary auditory cortex for
Sound
what is the amygdala and the hypothalamus for
Taste
what is the primary sensory cortex for
Touch
