Phonological Loop - WMM Flashcards
What does the phonological loop deal with?
Voicing of auditory of information.
What are the 2 parts that the phonological loop splits into?
1 - primary acoustic store
2 - articulatory loop
What does the primary acoustic store do?
Holds auditory memory traces that decay within a few seconds.
What kind of forgetting is forgetting in the primary acoustic store?
Forgetting by trace-decay.
What does the articulatory loop do?
Revives memory traces by rehearsing them.
Sound information goes directly into?
The primary acoustic store.
What is the primary acoustic store called?
The ‘inner ear’, because it remembers sounds in their order.
What is the articulatory loop called?
The ‘inner voice’, because information is repeated to maintain the trace.
Duration of information in the phonological loop before decay?
About 2 seconds.
Where does evidence for the phonological loop come from?
Studies that use sets of numbers, letters or words to see how many can be rehearsed & recalled, and to see which characteristics affect recall.
What affects rehearsal in STM?
Sound
What doesn’t affect rehearsal in STM?
Meaning
What affects rehearsal in LTM more?
Meaning
What has to be different when testing LTM?
Learning and recall are to be left longer.
Phonological similarity makes recall…
… difficult.
What neurophysiological evidence is there for the phonological loop having an articulatory system?
The left temporoparietal area has lesions if someone has phonological STM defects.
Function of the phonological loop?
Learning language
What evidence is there that the function of the phonological loop is learning language?
An individual with a phonological loop deficit can’t learn new vocab, even though their long term memory is, verbally, normal.
