exam 3 Flashcards
how does learning impact us?
changes to our nervous system and changes to our behavior
what is memory
long term changes in the nervous system
what are the four stages of memory?
encoding, consolidation, storage, and retrieval
what is stimulus response learning?
performing a specific behavior on the presence of a specific stimulus
what are the two types of stimulus response learning?
classical conditioning and operant conditioning
what is classical conditioning?
when a meaning is given to a previously neutral stimulus
what are the four main terms associated with classical conditioning?
unconditioned stimulus, unconditioned response, conditioned stimulus, and conditioned response
what is it when a dog salivates to meat?
unconditioned response, reflex
what is it when a dog salivates to the ring of the bell associated with meat?
conditioned response
What was Hebb known for?
neurons that fire together wire together
what is operant conditioning ?
an association between stimulus and response
what are the four main terms associated with operant conditioning?
reinforcement, punishment, positive and negative
when we do things that have reinforcements we get what chemical?
dopamine
what are some examples that give humans dopamine?
sex, cocaine, water, and food
what is perceptual learning?
recognition of stimuli we have seen before like logos
what is an example of relational learning?
when we hear meow we associate it with cat
going from short term memory to long term memory is called what
encoding
going from long term memory to short term memory is called what
retrieval
what are the two types of memory in long term memory
declarative memory and non-declarative memory
what is non declarative memory
auto pilot memories, automatic behavior
what is declarative memory
specific memories
episodic and semantic memory are part of what memory
declarative memory
what is semantic memory
stuff learned at school, facts, history
what is needed for memories to go from sensory memory to short term memory
attention
what is amnesia
loss of memories such as facts, information and experiences
anterograde refers to
new memories
retrograde refers to
old memories
what is the most common type of dementia
Alzheimer’s disease
what is korsakoffs syndrome
memory loss disorder associated with alcoholism
what is a stroke
blockage in the brain artery
what are seizures
sudden uncontrollable disturbances
what is encephalitis
inflammation in the brain
who was Henry Molaison?
individual who had epilepsy and had a surgery where they removed a portion of his brain, had memory loss of, however was still had procedural memory
what is an example of procedural memory?
tracing a star by the reflection of a mirror
what is an example of perceptual learning?
umbrella drawing
what is LTP
a synaptic strength between hippocampal neurons associated with memory and learning
what is sensitization
increased response to a frequently repeated stimuli
what is habituation
decreased response to a frequently repeated stimuli
in LTP what is released when action potential is present?
glutamate
in LTP what chemical signals for a higher number of AMPA receptors
calcium
in LTP what does the increase number of AMPA receptors lead to?
increase in AMPA causes for more sensitivity to glutamate, when more sensitive more likely to be activated
what is neuroplasticity
the reorganization or alteration of connections following experiences or following injury
