Memory and forgetting L5 Flashcards
3 main elements of memory
sensory store
short term store
long term store
where are sensory stores kept
visual neurones
what are short term stores
need to keep thinking about it to remember
what is retrieval failure in LTM
information still held but can’t be retrieved
what can make retrieving a memory harder
interference from other similar memories
sematic encoding=
meaning of a word/ does it fit it sentence
physical encoding
e.g capitals
acoustic encoding
rhyme
what is context dependancy
the environmental conditions where you learn makes a difference to how well you remember it
what is state dependancy
you can recall information better when you feel the same as when you learnt it
two long term memory stores=
hippocampus
anterior temporal lobe
what is damaged in sematic dementia
anterior temporal lobe
where is episodic memory found
hippocampus
what is episodic memory
unique experiences of people/place/object
what is sematic memory
similarities between memories to create concepts
where is sematic memory stored
anterior temporal lobe
what is important for memory consolidation
slow wave sleep
how is episodic memory encoded in the hippocampus
neurones in the hippocampus bind together things in memory to re-instate the full picture of the memory
how is memory retrieved in the hippocampus
one element of a story is a clue
what is Korsakofts syndrome?
long term alcohol causing memory issues
what is the only part of memory affected in hippocampus or medial temporal lobe lesions
Episodic
what is preserved in amnesia
non-declarative memory
sematic information
after a head injury what is memory like
poor retrieval of events just prior to event
normal retrieval of events from childhood
over time what happens to memories
become more reliant on neocortex and less dependant on hippocampus
where is place stored
in parahippocampal area
where is object stored
in inferior temporal cortex
where is people stored
in anterior temporal lobes
what is sematic dementia a subtype of
frontotemporal dementia
what do you lose in sematic dementia
factual knowledge
what remains intact in sematic dementia
memory for recent events
language
visual-spatial skills
non-verbal reasoning
what is the reverse temporal gradient in sematic dementia
remember recent events but not childhood
