Transcript Storage and Retrieval

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?
 Eidetic

 Very
complex system
 MEMORIES
DO NOT RESIDE IN SINGLE
SPOTS- Equipotentiality
 Biological
Basis
 Neuron
(Nerve Cell)
 Synaptic
Junction

 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
 Library
 Every
Book Analogy
time a memory is retrieved and
reconsolidated, it changes slightly
Memory
Short-Term
Memory
(Working)
Long-Term
Memory
Implicit
(Innate)
Explicit
Semantic
(General
Knowledge)
Episodic
(Events)
Procedural
(Brushing
Teeth)
Conditioning
(Hot Stove)
 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?
