Short/Long Term Memory
Does short term memory involve the hippocampus
NO
Whats recency effect?
Short term memory, words just said at end of the list, no interuption
what is episodic memory?
involves retracing the experience: think about what time it was, where you were, who you were with, think about the whole story and feelings
what kind of memory is the hippocampus critical for?
declarative memory- especially episodic
what kind of memory was window?
false memory- semantic
What brain structures are the main ones for each?
Short: prefrontal cortex
Long: hippocampus
whats primacy effect
Long term memory, trying to rehearse and rememeber words in beginning the longest and best
what is semantic memory?
What is perception of an event or episode?
a pattern of connected neural activity distributed throughout the brain
what was the graph called?
serial probabilty curve (serial position on x axis and number of people who recalled y axis)
can something in your long term memory be brought to short term memory?
YES
whats an example of something you can do that will disrupt primacy effect?
do something to prevent rehearsal by saying words really fast, or use a dual task
what is an example of each?
episodic: what did I eat for dinner last night
semantic: what is a typical thing to eat for dinner
What is an event or episode represented as?
a pattern of activity wthin th ehippocampus itself
what were the 3 observations?
primacy effect, recency effect, particular word (sill)
Do they depend on when you learned something?
NO! all information is present in LTM unless it is actually brought to mind
What is something that will disrupt the recency effect?
wait longer between writing down, give a distraction
is this declarative or nondeclarative memory?
declarative
whats long term potentiation?
used for synaptic consolidation and is a persistent strengthening of synapses between neurons based on recent, high-frequency activity patterns
what kind of memory would it be if you said word in funny way?
episodic memory
Which is limited and which is unlimited capacity?
short: limited
long: unlimited
Why do people have false memory?
because human memory is a constructive and reconstructive process, meaning the brain often fills in gaps or alters the order of events to create a coherent story
in the class demo which kind of memory is related to nick specifically saying door?
which kind of memory is related to the word window?
episodic
semantic
whats system consolidation in neocortex
the time-dependent process where memory traces gradually become independent of the hippocampus and reorganize within neocortical circuits for long-term storage
is the primacy effect a long term memory or short term advantage
long term
