Working Memory Flashcards
working memory
mental workspace where we hold information to use in a short period of time
serial position curve
we tend to remember words at the beginning and the end of a list
primacy effect
tendency to remember things at the beginning of a list
affected by LTM, not affected by working memory
recency effect
tendency to remember things at the end of a list
not affected by LTM, affected by working memory
what are the three components of Baddeley’s working memory model?
visuospatial sketchpad
cental executive function
phonological loop
visuospatial sketchpad
stores visual and spatial input
central executive function
involved information processing
phonological loop
stores auditory input
acoustic similarity
confusable lists are worse to recall than non-confusable lists
errors in mixed lists lead to substitutions of similar-sounding words
confusions occur if words sound alike, but not for words with similar meaning or words that are similar-looking
articulatory suppression
if you’re doing two things that require the same brain machinery simultaneously, you can’t store information in the phonological loop
effects of articulatory suppression
lowered accuracy of recalling lists
acoustic confusion effect disappears
limits to the phonological loop
chunking effect because of storing capacity
time effects due to decay and speeed of rehearsal
how long does subvocal rehearsal process information last in the phonological loop?
approximately 2 seconds
how many chunks of information can one remember?
5-9 chunks
word length effect
subjects can remember about as many words as the can say in 2 seconds
