MEMORY
Forgetting
permanent memory loss
anterograde amnesia - can recall past, but not form new memories
HM - removal of hippocampus, so can't form new episodic memories
-
Clive Wearing
-
-
but still have motor skills (piano), and implicit memory (guess at year/time of the day)
-
-
-
storage decay - curve fast, then slowly
-
interference
proactive interference - forward acting disruptive effect on old learning on recalling of new memories
retroactive interference - backward acting disruptive effect of new learning on recall of old memories
but not always compete, can enhance each other
motivated forgetting - dont accurately recall information eg repression: banishes unacceptable memory
suppression: when stop thinking about sth, repression: didn't consciously stop thinking about sth, automatic

memory models
-
-
-
memory forming process
record as fleeting sensory memory: immediate, brief recording of sensory infojm
process to short term memo: activated memory that can hold a few info briefly, before either rmbed or forgotten
working memory: newer understanding, focus on conscious, active processing of sensory info

Memory Storage
-
-
-
Amygdala, Emotions and memory
stress provokes amygdala to initiate memory trace in frontal lobe and basal ganglia - boosts memo formation , and induces adrenaline
-
-
flashback memory: clear memory of an emotionally significant moments or events/ more dramatic = more accurate memory
Synaptic change
-
-
increase long term potential: increase in cell's firing potential after brief, rapid stimulation
confirmed by drug blocking LTP interfere with learning,
-
Retrieval cues
-
-
state-dependent memory - drunk/sober, mood
serial position effect
-
-
bc 1st word repeated so much it is transferred to long term memory, last word lingers and disappears
-
-
Level of processing
-
-
deep processing eg encodes semantically, based on meaning of words
dual track memory
implicit memory: learned skills or classically conditioned associations indpt of conscious recollection
-
-
-
-
how studied
works in 17 years as well, even though those candidates don't rmb being in the same study
-
implicit recognition = the polygon, reacting to it
(controversial) Arrange words like florida and bingo (that's associated to slow) and can cause a person to walk slower
