memory Flashcards
memory
way in which we record past events and knowledge
three things needed to happen for memory
acquisition, storage, retrieval
acquisition
we have to learn it the first time, even if you acquire it doesn’t mean you have it in your head
storage
hold onto it/store it (tip on your tongue is failure to retrieve it from storage
retrieval
be able to recount on it/go back and find it
sensory register
large capacity and short duration
demonstrated by Sperling’s partial report procedure
sperling’s partial report procedure
show participants a matrix of letters for 500 milliseconds, asked to report as many letters as they could, couldn’t tell how much they held since it was displaced by new information, came up by training them in advance by memorizing three tones of a bell (one tone per row), 500 milliseconds again and then tone, could recite it better when “chunked” into different rows, demonstrated that entire array was there but only for a really short time and only report part of it
echoic sensory register
duration for 1-3 seconds, hearing register
short term memory
small capacity of seven (give or take two)
duration of 15-30 seconds
keep things there longer by focusing attention on it or leaks away/bumped out
long term memory
large capacity
can’t fill up and keep things in there for years
dual track memory
implicit and explicit
implicit
non-declarative/unconscious
space, time, frequency
procedural
classical conditioning associations
procedural
things you know how to/your how-to memories (ex. riding a bike)
classical conditioning associations
learned taste aversions
can’t directly tap into but is just there
(ex. fear, reactions to all types of things due to past experiences)
explicit
declarative, conscious
semantic and episodic
semantic
memory for meaning
episodic
memories for events/experiences
recognition
recognizing the object
free recall
placing the object
