theory of reconstructive memory (bartlett)
memories are not exact copies of events but interpretations (schemas)
barlett: war of the ghosts (1932)
aim: testing the nature of reconstructive memory using an unfamiliar story
procedure: 20 participants asked to read a story twice and then recall later on
results: participants tended to add meaning to story, left unpleasant parts out
conclusion: evidence for reconstructive memory. participants didn’t recall accurately or fully
evaluation of bartlett (1932)
strength: real life application, eye-witness may misremember information, validity
weakness: used his own interpretation, interpretated each participants recall, lack reliablity
peterson & peterson (1959)
aim: to test the true duration of STM
procedure: participants were asked to recall 3 digit numbers, then 3 letters, then count backwards on 3/4s
results: longer each student had to count backwards, less likely to accurately recall 3 letters
conclusion: STM fades rapidly. only 10% could be recalled after 18 seconds
evaluation of peterson & peterson (1959)
strength: highly controlled, lab experiment of a university, controlled extraneous variables, valid
weakness: only used 24 psychology students, memory of psychology students may be different, may know ways to improve memory, ungeneralisable to others.
reductionism v holistic
reductionism: describing something into its basic parts, used in lab experiments to isolate factors and for high control. e.g. MSM of memory
holistic: looking at different variables in relation to something happening e.g. barlett
strengths & weakness: MSM of memory
s: real life application, rehearsal can be needed for eye witnesses , tells us how to improve memory
w: lack ecological validity, e.g peterson, unrealistic
anterograde amnesia
only remember things before brain damage
retrograde amnesia
only remember things after the event
short term memory
18 seconds without rehearsal, 7+-2 items, acoustic, forgetting: displacement and decay
long term memory
a few seconds to a lifetime, semantic coding, forgetting: decay, interference and retrieval failure
accommodation
schema changed due to a new experience
assimilation
incorporating new ideas into existing schemas
adaptation
use of both assimilation and accommodation
evaluation of reductionism
s:
evaluation of holism
s:reflects real experiences, as it takes multiple different measures, ecological validity
w:lacks scientific nature, relies on subjective accounts, low in reliability
