sensory memory
very brief
raw sensory data
large capacity, short duration
short term / working memory
holds info you are currently using
limited capacity
duration: 20-30 seconds
long-term memory
stores info indefinitely
nearly unlimited capacity
includes knowledge, skills, experiences
working memory
a modern update of short term memory
episodic long term
personal experiences
semantic long term
facts and knowledge
implicit (non-declarative) memories
influence behavior automatically
1. procedural- skills
2. classical conditioning- learned associations
3. priming- previous exposure influences later behavior
how to test memory and how to know capacity
memory tests:
recall- remembering without cues
recognition- identifying the correct option (multiple choice)
relearning: measuring how much faster you re learn something
capacity:
sensory memory- very brief flashes
working memory- digit span tests
long term memory-
what parts of the brain encode and store explicit memories
hippocampus:
transfers new explicit memories into long-term storage
damage-> anterograde amnesia (can’t form new memories
Frontal Lobes:
store and retrieve explicit memories
left= verbal, right= visual/spatial
what parts of the brain encode and store implicit memories
cerebellum- classical conditioning
basal ganglia- procedural skills and habits
amygdala- emotional memories
what is long term potentiation and how is it related to memory
def: long lasting strengthening of synapses due to repeated stimulation, memory improves if it increases
