Memory Flashcards
Memory
Nervous system’s ability to retain representations
Stages Of Memory
Encoding - Storage - Retrieval
Consolidation
The neurobiological process of turning a temporary representation into a lasting one.
Reconsolidation
The neurobiological process of restabilizing a reactivated, and thus flexible, memory
Dissociations
When one manipulation affects
one process but not another
Types of Memory
Long Term & Short Term
Short term memory
Allows you to experience continuity in the world
Working Memory
Sensory Short-Term Memory:
Echoic memory
Ionic memory
Sensory Echoic memory
Brief persistence of sound after the stimulus is gone
Sensory Iconic memory
Brief persistence of vision after the stimulus has gone
Working Memory
Short Term
An active processing system that keeps different types of information available for current use.
EG: remembering a phone number you just received.
Long Term Memory
Storage of memories receding further back in time.
Declarative memory
Episodic memory
Semantic memory
Nondeclarative memory
Procedural memory
Declarative Memory
Memory of facts and events
Episodic Memory
Semantic Memory
Episodic Memory
Autobiographical life experiences
EG: A vivid memory or an event.
Semantic memory
Factual information
EG: Names & dates
Implicit/nondeclarative memory
Requires repetition and practice, less likely to be forgotten
Works without conscious recollection (like reflexes)
Procedural memory
Procedural memory
Skills, habits, behaviors
EG: Riding a bike
Spatial memory
2 ways to learn
Place
You’ll find the reward because you remember where it is no matter what your starting point is
“remembering”
Uses hippocampus
Response
You won’t find the reward because you only remember how to get to that reward which won’t help you if you’re at a different starting point
“habit”
Uses striatum
Types of Amnesia
Retrograde Amnesia
Anterograde Amnesia
Global Amnesia
Retrograde Amnesia
Loss of old memories
Anterograde Amnesia
Can’t make new memories
Global Amnesia
Both
Things that people with amnesia are bad at
Remembering what happened yesterday (lowest recollection)
Recognizing things they’ve seen
Recalling things from memory
Things amnesia patients are good at
Remembering new physical skills
Perception
Priming
Remembering new conditioning
Ability to remember facts (semantic memory)
Priming
Seeing something once prepares the visual system to see it again
Long-term Potentiation
When repeated stimulation from the pre-synaptic neuron makes it easier for the post-synaptic neuron to fire
Neurons that fire together,
wire together
EPSP
Cell Assembly
A group of neurons that are repeatedly active at the same time and develop as a single functional unit, which may become active when any of its constituent neurons is stimulated.
Long Term Depression
Opposite of Long Term Potentiation
IPSP
