Module 8: Short-Term & Working Memory Flashcards
what is the process involved in retaining and using info about stimuli after the original info is no lo nger present
memory
___ experience has an impact on how you think or behave now or in the future
past
developed by atkinson and shiffrin 1968
modal model of memory
types of memory (structural features)
sensory, short term, long term memory
initial stage. holds all incoming infor FOR SECONDS or FRACTIONS of seconds
sensory memory
holds 5-7 items for ant 15-20 seconds
short term memory
can hold large amount of info for years or even decade
long term
active processes that can be controlled by the person
control processes
it is the retention for brief periods of time, of the effects of the sensory stimulation
sensory memory
retention of the perception of light
persistence of vision
measuring the capacity and duration of sensory memory (sperling, 1960)
sperling’s experiment
array of letters are flashed quickly on screen and participants are asked to report as many as possible
sperling experiment of measuring the capacity and duration of sensory memory
ave 4.5 out of 12 letters (37.5%)
whole report method
participants heard tone that tells them which row of letters to report (ave. = 3.3 out of 4 letters 82%)
partial report method
presentation of tone delayed for a fraction of second after letters were extinguished (performance decreased rapidly)
delayed partial report method
the ⬇️ in performance is due to the rapid decay of ___
iconic memory
brief sensory memory of what we see (visual - for seconds)
iconic memory
brief sensory memory of what we hear (auditory- for 1 second)
echoic memory
does NOT REQUIRE attention for the attention to be maintained
sensory memory
relatively. automatic
sensory memory
to retain info (sensory memory) for LONGER periods, it must be transferred to ___
STM
stores SMALL amount of info for BRIEF DURATION
STM
includes both new info received from sensory stores and info recalled from ltm
stm
3 types of code in STM
visual
phonetic
semantic -meaning
