Modules 25-26
Part 1
Raw, unprocessed
information
Sight, touch, smell, sound, taste
Stimuli
Changes
Selection
for further processing
Integrates
sensory fragments into
perception
Sensory
Memory
STM
Long
Term
Memory
Listen
carefully and write each series of
digits on a scrap piece of paper after I
finish reciting them.
Should
have been about 7 digits.
May
have been slightly higher because
recall for random digits is better than
random letters.
Why
might that be?
Space
is limitless.
Genetic?

Long-Term
Potentiation: Strengthened
neural firing, creating more permanent
pathways for memory.
When
neurons “fire together”, they “wire
together”.
Billions
of Connections
Neural
connections that support memory
become stronger- Medial Temporal Lobes

time a memory is retrieved and
reconsolidated, it changes slightly

Remembering
future time…
to do something at some
1. Walking
(for an adult)
2. The value of pi to six decimal places
3. Writing a computer program
4. The fact that working memory is brief
5. The fact that you need to drive your
sister home from school
6.The fact that the smell of eggs makes
you sick and you don’t know why
Hippocampus
- Processes Explicit Memories
- Transfers to other areas for storage
-Works with frontal lobe- thinking area
Cerebellum
- Stores implicit memories
-Right above spinal cord
- Evolutionarily/Developmentally older
Amygdala
- Processes emotional memories
- Plays a role in stress/fear conditioning
- Strengthens these memories
Infantile
Amnesia:
- Learn most reactions/skills during first
three years, but we have no explicit
memory of these events.
This
dual system might explain why
therapists spent many years investigation
the influence of childhood experiences…
Permanent
effects may be a result of
implicit memory, not explicit.
Part 2
Seven
Dwarfs: List vs. No List
Recall:
1. Must List Information/Options
2. Eliminate Wrong Choices
Recognition: Only
Choices
Eliminate Wrong
How mnemonics work
The word element might trigger the following:
Situational
Scuba
Déjà
similarity helps memory
experiment
vu
I’m Really
Angry
Wow…they
were really
mean
When I was
five, my
parents yelled
at me about
organizing my
money
Remember
that time my
wallet was
stolen
I’m angrier
How might the mood-congruent theory explain
the human experience of good vs. bad days?
Karma?
