module 24 - storing and retrieving memories Flashcards
1
Q
where are memories stored
A
distributed across various regions of the brain
2
Q
how do we build memories
A
abstract patterns of neural firing
3
Q
reactivation of brain parts
A
much of the same brain activation that was present when experiencing something is reactivated when remembering that experience
ex: visualizing something you remember seeing has similar neural firing to when you were actually seeing it
4
Q
explicit memory
A
- Semantic - facts and knowlege
- SF is in california
- episodic - experiences we can relay in our mind
- remembering your first date
- formed but not stored in the hippocampus
5
Q
implicit memory
A
- associations created by conditioning stored in the cerebellum
- memories for procedures stored in the basal ganglia
6
Q
effect of emotion on memory
A
- emotion enhances encoding of memory (suggests meaning or importance)
7
Q
flashbulb memories
A
- vivid memories of intense, unexpected events
- illusory confidence (not necessarily accurate)
8
Q
recency effect
A
- type of serial position effect
- items near the end of a list are easier to recall than items in the middle
- still in short term memory
- fades if there is a delay before testing
9
Q
primacy effect
A
- type of serial position effect
- items near the beginning of a list are easier to recall than items in the middle
- proactive interference
10
Q
consolidation
A
- encoding information into a stable, long term memory
- mostly occurs during sleep
11
Q
Long-term potentiation (LTP)
A
- repeated communication between neurons strengthens their synaptic connection
- Hebb’s law: “cells that fire together wire together”
12
Q
retrieval cues
A
- elements associated with the memory that help retrieval
- Ex: being in the same mood, state, or environment you learned it in
