types of LTM + WMM Flashcards
what are the 3 types of LTM?
episodic
semantic
procedural
episodic memory?
memory of personal events & experiences
time stamped
remeber emotions, context + people
examples of episodic memories?
dentist visit, bday parties
semantic memory?
memory of facts/knowledge of the world
same for everyone
not personal
examples of semantic memories?
taste of an orange, meanings of words
procedural memories?
knowledge on how to do things
most easy to recall
acquired through repetition + practice
examples of procedural memories?
tying shoelaces, swimming, how to read
who studied the different types of LTM
tulving et al
strengths to tulving’s study of LTM
supporting research
clive wearing suffered from amnesia
some areas of his LTM was intact (P + S)
E memory was damaged
explanations are valid
another strength to tulving’s study of LTM?
patient scans
ppts performing diff memory tasks while doing a PET scan
S memories - left prefrontal cortex
E memories - right prefrontal cortex
physical evidence
weakness of tulving’s study of LTM?
case studies
one case cannot apply to everyone
lacks generalisability
another weakness of tulving’s study of LTM
psychologists disagree
argue that E + S memories are stored together bec they require conscious recall
unlike P memories
further research needed
baddeley + hitch: name components of WMM
central executive
phonological loop
episodic buffer
visuo-spatial sketchpad
what does the central executive do
controls everything
has limited capacity
designated info to the other stores
what does the phonological loop do
stores info relating to sound
limited capacity
acoustically coded
phonological store: stores words you hear
articulatory process: maintenance rehersal
what does the episodic buffer do
integrates info
recent addition to the model
bridge for LTM
what does the visuo-spatial sketchpad do
holds visual + spatial info
retains shapes + colours
holds info on locations
what are the two sections of the visuo-spatial sketchpad
visual cashe: visual data
inner scribe: record arrangement
what are the two sections of the phonological loop
phonological store: stores words you hear
articulatory process: maintenance rehearsal
strengths of the WMM
supporting clinical evidence
KF case study = STM worked independently from LTM
STM forgetting of audio was greater than visual info
proves there are 2 short term memory stores
