5 - Theories of Memory Flashcards
anterograde amnesia
the loss of the ability to craete new memories after the event that caused amnesia
who was HM?
- pt who suffered from severe seizures
- had bilateral medial temporal lobectomy - removed hippocampus and amygdala
- stopped seizures, but unable to form new memories
- could still develop procedural memory however
what is memory?
- mental capacity to store and later recall or recognise events that were previously experienced
what is the basic memory processes?
encoding - storage - retrieval
what are the 3 ways memory can be encoded?
acoustic
visual
semantic
what are the 2 ways memory can be stored?
LTM
STM
what are the 2 ways memory can be retrieved?
recall
recognition
recall
accessing information without cues
recognition
identifying information
draw the multi-store model of memory
how long does sensory information last?
0.1-0.5 sec
what does sensory memory hold?
accurate and complete representation
encoding of sensory memory is what?
sense-specific - there are different sensory memory stores for the different sensory modalities
what is the duration of STM?
seconds - minutes
what lobes are involved in STM?
sensory and parietal
what is the capacity of STM?
7+/-2
what is the duration of LTM?
potentially unlimited
what is the capacity of LTM?
possibly unlimited
what is essential for consolidation of LTM?
- hippocampus
- sleep
what is the encoding of LTM?
mainly semantic
