Memory and Learning Cont. Flashcards
fast glimpse of something that isn’t stored
sensory buffers
usually last about 30 seconds or throughout rehearsal
short-term memories (STMs)
last days, weeks, months or years
Long-term memories (LTMs)
its not meant for us to recount our complete lift histories, but to record important events that we can use to:
shape our future behavior in adaptive ways
sensory information is brought into STM
encoding
transferring information from short to long term memory/storage
consolidation
taking info out of long-term storage for use in working memory
retrieval
LTM has a vast capacity, but is subject to … - pruning of unimportant memories to preserve cognitive resources
forgetting
the … does not deteriorate over time but is interfered with by other events that occur before or after their formation
memory trace
the process of retrieving info from LTM can cause memories to become unstable and susceptible to …
disruption or alteration
is the return of a memory trace to stable, long term storage after recall
reconsolidation
the ability of neurons and neural circuits to be remodeled in response to experience or the environment
neuroplasticity
synaptic changes that may store info can be presynaptic, postsynaptic, or both
- this can include changes in the … or changes in
number or sensitivity of postsynaptic receptors
- new synapses may also be formed!
amount of neurotransmitter released
lab animals living in a complex environment demonstrate biochemical and anatomical brain changes, 3 housing conditions…
- standard condition (SC)
- impoverished condition (IC)
- enriched condition (EC)
- heavier, thicker cortex
- enhanced cholinergic activity
- more dendritic branches and spines on cortical neurons
- larger cortical synapses
- more neurons in the hippocampus
- enhanced recovery from brain damage
animals housed in EC developed:
