strategy for improving recognition
priming
priming
exposuing to stimulus to make it more recognizable
zeigarnik effect
if stuck, brain keeps working on it
redintegration
something rapidly unlocks a chain of memories
flashbulb memories
usually traumatic, great detail
prospective memory
what you were going to do
eyewitness
not reliable, STM better than LTM
hippocampus
in temporal lobe, consolidation of LTM
HM anterograde amnesia
frontal lobe
susceptible to Gsm problems and interference
brain parts for memory
hippocampus
mamillary bodies
thalamus
temporal cortex
frontal lobe
basal forebrain
+ACh
STM becomes LTM by
Long term potentiation
repeated stimulation of synapse change dendrite, increased sensitivity to stimulation
Involves kinases
Ebbinghaus
forgetting
serial position effect
on immediate recall, remember beginning/end better
On delayed recall, remember beginning better, middle/end the same
paramnesia
distorted memory, involves confabulation
retroactive interference
recently learned info interfere with recall
proactive interference
previously learned info interfere with learning new stuff
mood-congruent memory
recall better when mood matches mood at learning
state-dependent memory
recall better in state similar to when learning
motivated forgetting
aka repression
Freud
method of loci
visual image in place while walkaround
pegword system
memorize images, hang them onto words
word associations
form words/sentences with first letters of words being memorized
substitute words technique
