Introduction to Memory Processes
From learning to memory:
You need memory to learn
•
Classical conditioning: unconditioned stimulus (UCS)
Automatically elicits an unconditioned response (UCR- reflexive eye blink)
Pair the stimulus CS (conditioned stimulus- tone) that will teach the
behavior that will elicit a CR (learned conditioned response, a
memory-blink)
§
Removed a tissue in the cerebellum which is associated with
learning and small motor movements such as eye blinks
§
○
•
Engram: long term memory
•
More on the Engram:
Engram is the historical term for the elusive "physical trace" of memory
(LTM=long term memory)
○
Conditioned response was located in the cerebellum
○
Explicit memory process: learning verbally
Hippocampus: important for verbal learning
If it's highly stressed, it stops generating new neurons cause
of the cortisol
□
§
○
•
When you develop new memories, you develop more synapses, the gaps
between the nerves in the brain
•
The brain does not develop past a certain age
•
William Greenough's Lab:
IV: independent variable - manipulated the enriched environment
•
ENVIRONMENT
DV: the four things that were measured (
•
What was manipulated?
The quality of environment
One enriched environment (toys and other rats)

One enriched environment (toys and other rats)
§
One poverish environment (cage)
4 different results:
Enriched environment: more input of neurons
◊
More dendrites
®
More synapses
More connections and growth
◊
Adding more synapses per neuron for rats in
enriched environments compared to controls
◊
Residue of experience, left over from experience
◊
"Wiring diagram was actually embellished"
Growth
}
◊
®
Blood supply (vascular supply)
More capillaries
◊
®
Glial cells
Take sugar and oxygen from blood and gives to
neurons
◊

§
○
EXERCISE
What was manipulated?
The quality of the learning experience
One was exercising like mad
Lots of new blood supply as result
□
§
One was getting a little bit of exercise but they were learning other
stuff
More dendrites, more synapses, and glial cells
□

○
•
We only remember stimulation that enters our sensory memory processes if it
Receives attention is conscious experiencing of one or more sensory
modalities
1.
Is held and maintained in stm (working memory
2.
•
The Prevailing Model
Sensory input --> 1. sensory memory unattended information is lost--> 2. short term
memory unrehearsed information is lost --> 3. long term memory Some information
may be lost over time
Maintenance rehearsal (2)
Short term memory = working memory
