memory Flashcards
what are the 3 processes involved in memory?
encode, store, retrieve
what are the 3 types of encoding?
acoustic, visual and semantic (words and their meanings)
which type of encoding makes for the best memories?
semantic, because it involves a deeper level of processing than visual or acoustic
describe the Atkison-Shiffrin model of storage
claims we process memories in the same way that a computer processes information. for a memory to go into storage, it has to pass through 3 distinct stages- sensory memory, short-term memory(15-30 sec), and long-term memory
episodic memories vs semantic memories
episodic memories are autobiographical–it happened to you; semantic memories are factual information (not necessarily what you think of in terms of the typical “memory”)
what is the amygdala’s role in memory?
because the amygdala regulates emotions, the amygdala helps to decide which information is important enough, or emotional enough, to be stored. the amygdala is involved in transferring new learning into long term memory (aka memory consolidation)
what is the hippocampus’s role in memory?
the hippocampus is where new memories are encoded; the hippocampus helps to connect new memories with old memories in other parts of the brain; helps to transfer information into long-term memory (memory consolidation)
what is the cerebellum’s role in memory?
allows one to create implicit memories (like procedural memory, motor learning, and classical conditioning) (implicit memories are automatic and unconscious)
what neurotransmitters influence memory? (5)
dopamine, epinephrine, serotonin, acetylcholine, and glutamate (___DeSAG___)
what is anterograde amnesia?
when you cannot remember any new information
what is retrograde amnesia?
when you cannot remember any old information
what are the 3 ways in which memory can fail?
forgetting, distortion, and intrusion (interference?)
