block 6 lecture 4 Flashcards
what are the three kinds of memory stores?
- sensory
- short term
- long term
what is memory important for?
adaptive behaviour and self identity
what system do you use to understand what you are seeing?
perceptual
how does sensory memory work?
the perceptual system has a buffer so you maintain perceptual info for half a second
how is information stored from the sensory memory?
you apply attention to it and repeat it
what is short term memory?
allocating certain
what is loss from short term memory from?
not allocating attention to that information
why may it be difficult to retrieve long term memory?
memories can be similar so it is difficult to pick out certain information
what is interferance?
not being able to pic out information because memories are too similar
what does levels of processing refer to?
weather you use meaningful links to remember things
how can you orientate memories?
physical appearance
acoustic sound
semantically
what is context dependency?
return to the environment you formed and you have better recal
what do you need to recall long term memories?
cue
what is mood dependancy?
mood can act as a cue to recall memory
why do you forget in short term memory?
information gets lost when you are distracted
what is involuntary memories?
recovering memories you hadn’t intended to
what are some common causes of amnesia?
viral infection alcoholism anoxia head injury alzheimers
what does the hippocampus do?
forms connections and supports memories
what structures are important for normal memory circutry?
parahippocampal cortex, fanix and mamillary bodies
what is an implication of Alzheimers?
cant form new long term memories
what is the evidence you don’t store long term memories in the hippocampus?
lesion in the hippocampus e.g. amnesia you still remember childhood memories
what is intact in patients with amnesia?
motor learning
unconscious memory
what type of memory is damaged with amnesia?
episodic
what are the two types of long term memory?
declarative and non declarative
what is the role of the hippocampus?
combining information to produce episodic memories
what happens to memory in amnesia?
binding process is disrupted
where does the hippocampus pass on memory to?
neocampus
what is semantic dementia due to?
damage to the neocorticol store of memory (progressive)
what is semantic dementia a sub type of?
frontotemporal dementia
when is semantic dementia diagnosed?
50
what are the consequences of semantic dementia?
difficulty understanding conversation
anomia
what is anomia?
when someone cant think of the right word
what area is affected in semantic dementia?
anterior termporal lobe
what is spared in semantic dementia?
memory for recent events
phonology and syntax
visual-spacial skills
non-verbal reasoning
what are the two long term memory?
hippocampus and anterior temporal lobes
