MEMORY
Topic Name(s) Research
Coding STM + LTM Baddeley Acoustically similar + dissimilar and Semantically similar
and dissimilar
Immediately, distracted by acoustically similar words so
stores info acoustically (evidence for STM)
After mins, distracted on meaning of words so LTM
stores semantically (LTM)
Capacity STM Jacobs Digit test to recall with digits then increased if they got
it correct = can remember . digits and . letters
Capacity STM Miller Can roughly absorb new pieces of info in STM ( +- ) -
also the case for chunking
Capacity LTM Wagenaar Created diary over events in it, recall % of one
detail after a year, after years % remembered
Capacity is large and maybe unlimited
Duration STM Peterson & Peterson Random trigrams (KHG,JIU) after retention interval
( , , … sec)and count backwards from a number to
avoid rehearsal = recall got worse after longer delay
Duration LTM Bahrick et al Photo recognition of yearbook = % if graduated within
years remembered and % within years
Free recall to say who they studied with = % within
years and % within years (LTM potentially
UNLIMITED)
Muti store model Glanzer and Cunitz Recall word list in any order, recall stronger for
STM and LTM beginning of list and weakest middle and some at end
First word rehearsed a lot (primacy e ect)
Most recent word at end (recency e ect)
Middle words in STM displaced for later words
Muti store model Sperling x letter grids and had to recall one row when seen for
Capacity / th of a sec
Recall for a row = % stored in iconic store so sensory
register is large
Muti store model Sperling When asked to recall all letters, only recalled - letters,
Duration faded from sensory memory before paid attention to so
Duration < second
Types of LTM Tulving
FMRI’s to identify which types of memory are associated
with which brain areas - gained idiographic case studies
