Apr 26 - Memory Flashcards
learning
acquisition of new information
memory
retention of learned information
declarative memory
(explicit)
facts and events
nondeclarative memory
(implicit)
procedural memory - motor skills, habits
> non-associative learning
> associative learning
non-associative learning
altered response to stimulus
habituation
diminished response following repeated exposure to a stimulus
sensitization
exaggerated response following exposure to repeated stimulus
associative learning
behavior altered by…
behavior altered by formation of associations between events
classical conditioning
(associative learning)
PAVLOV:
pairing of unconditional stimulus with conditional stimulus (teaching a dog lunch time is when bell rings)
instrumental conditioning
(associative learning)
associate a response with a meaningful stimulus
(rat and feeding lever)
working memory
(declarative memory)
temporary storage, lasts seconds
small capacity - limited storage
short-term memories
(declarative memory)
(vulnerable to disruption)
- facts and events stored in short-term
- subset are converted to long-term
long-term memories
(declarative memory)
recalled months or years later
memory consolidation
(declarative memory)
process of converting short > long-term memory
regions of the brain assoc. w/working memory
frontal lobe > prefrontal cortex
- self-awareness, capacity for planning and prob solving
- frontal lobe has sustained activity during delay period
> prefrontal cortex lesion = deficit in working memory
