HCF - Memory Flashcards
Difference between learning and memory
learning is the process of acquring new info about the world - memory is a product of learning
Name the 3 stages of memory
Encoding
Storage
Retrieval
Describe the modal model
sensory memory -(encoding)-> short term memory long term memory
How long can info stay in each type of memory
Sensory - 0.5-3 seconds
STM - 10-15
LTM - forever but lost over time
What is your sensory memory
contains about 12 items
echoic + iconic
How do items shift from sensory –> STM
attention
how do you keep info in your STM
active rehersal
What case studies cast doubt on Model modal and why
LTM can be intact in spite of impaired STM
What is the craik and lockheart model
depth of info processing that determines how well you remember it. depending on meaning
Baddely and Hitch say that….
there is a central processor , the brain activities show increased activity in frontal lobe when the central processor is working.
Describe the 4 memory systems
episodic - explicit events / the pasy
semantic - explicit facts/ knowledge
working - explicit phonologic phone number, spacial - mentally following route
procedural - explicit and declarative driving a car
what does explicit/declarative memory mean
conscious
Name the area of the brain responsible for each type of memory
episodic - temporal love (hippocampus) amygdala
semantic - inferolat temporal
working - prefrontal
procedural - cerebellum, supplementary motor area
two different types of amnesia?
retrograde b4 and anterograde after
What happened to HM
bilateral removal of mid temporal lobes. anterograde amnesia
also developed retrograde for 3 years before the op (suggest consolidating memory takes time)
working and procedural memories okay (could learn new tasks)
couldn’t recognise people he had met since the operation
