psych part 3 Flashcards
what is the modal model of memory storage
input comes in trhough the ears and goes into sensory memory then it goes into short term memory from there some memories are tossed completley, some stay with repetiton and some make it to long term
what is the sperling task
12 letters flashed then repeat what u saw
partial report is what
you have 12 letters but u have to say what row u saw what letter on this method is 75% more accurate but when sound delayed only 30%
what is masking in memory
masking erases that original piece of info if its presented to quickly
short term memory is…
is any info thats made it past the attenuator
digit span task
numerous trials with different sets of numbers
george miller and magic number 7
he believe that humans could only remember up to 7 digits before they started forgetting
whats the scanning task
scanning through numbers or letters to find the probe
parallel scanning
is seeing all the letters at once then seeing if the probe was there this strategy is too fast
serial strategy
go thru each one and stop when u find it
exhaustive strategy
go thru each one even after u found it
working memory capacity
memory for visual stimuli
articulatory suppression
restricting somone from repeating back words
central executive functions
controlled processing in working memory and decision making
phonological loop
speech and sound related componet of working memory
episodic buffer
the link between working memory and ltm
what is categorization
a mental representation of an object or event
categories vs concepts
categories are broad concepts are specific
what is typicality

global/super basic and specific/sub
an animal is an example of what category
global
a gold fish is an example of what category

how does spreading activation work?
When the word chocolate was processed, it may have activated the node for cookie via spreading activation, leading to participants thinking they remembered the word cookie being on the list.
whats the lexical decision task
how long it takes to see if a word is real or not
what is the connectionist model
knowledge is distributed rather then being localized and that it is retrieved through spreading activation
