Topic 6 Flashcards
Declarative memory
Facts, events, knowledge about the world etc
recalled consciously
easily formed and easily forgotten
Non-declarative memory
Recalled unconsciously
things like how to form a specific skill
longer lasting
formed through repetition
Types of non-declarative memory
associative and non-associative learinng
Associative learning
When a stimulus triggers and outcome
the is an association between the two things
two types
classical conditioning and operative training
Pavlov’s experiment
unconditional stimuli - unconditional response
neutral stimuli + unconditional stimuli - unconditional response
conditional stimuli - conditional response
Conditional responses
Are not permanent
Operant conditioning
the second type of associated learning
when a person or animal learns that certain behaviours are rewards and certain behaviours are punished
the positive behaviours are more likely to be repeated and the negative ones are less likely to be repeated
Non-associated learning
The second type of Non-declarative memory
2 types
habituation and sentization
Habituation
When a person or animal becomes desensitised to a stimulus because the brain views it as non-threatening
i.e living next to train tracks
Sensitization
When a person develops an exaggerated response to a stimuli
usually happens when you have a traumatic experience
Memory consolidation
Turning short-term memories into long-term memories
sensory information - short-term memory - consolidation - long-term memory
engram
what memories are stored as
Hebbian Theorey
Neurons that fire together, wire together
synaptic connections between neurons are stronger when they are fired together
therefore when one cell fires it is easier to for the others to fire
cell assembly is all the connected neurons
Hebbain modification
repeated exposure to a stimuli strengthens the connects
Rhino Cortex
the circuit for remembering declarative memory
1- sensory informatin is processed in parietal, occiptial and prefrontal coretx
2- information travels through parahippocampus gyrus and rhino cortex
3 - sent to hippocampus
4- sent to thalamus and hypothalamus
