1. A little bit of History & Fun Facts 2. How it might work & Diff erent types of Memory3. What We Still Don’t Know4. The College Life of Marcus Wallace
TABLE OF CONTENTS
Study of Memory dates back 2000 years – Aristole’s time
First hypothesis: Natural and Artificial 1880’s: fi rst scientific approach to Memory by
German philosopher Herman Ebbinghaus by conducting experiments
1949: Accepted theory of “neurons that fi re together, wire together” – Discovered by Donald Hebb
1968: Atkinson–Shiff rin model
A LITTLE BIT OF HISTORY & FUN FACTS
Over 100 billion neurons Max capacity of our Short-term memory – 7 digits TV kills your memory – Additional 1 hour per day
increases development of Alzheimer’s by 1.3% in later years
The brain produces enough electricity to power a light bulb
SOME FUN FACTS
Alexander the Great remembered all the names of his soldiers – just 30,000
Mozart was able to play and write down all the notes from a song he heard – only once
SOME MEMORY GURUS
Various Models – currently accepted is “The Working Memory Model”
Three diff erent stages: Encoding, Storage, RetrievalMain Players: Frontal Cortex, Hippocampus, NeuronsVarious factors aff ect Memory
HOW IT MIGHT WORK
Short-term or “working memory”: Present conscienceness – lasts only 20-30 seconds
Long-term Explicit
Episodic Semantic
Implicit Procedural
DIFFERENT TYPES OF MEMORY
Used to believe memory was stored in the cortexes – but may not be fully true
Unsure of how exactly regions of the brain know when to store a memory
New discoveries: Hyperthymesia - condition of extremely detailed autobiographical memory Marilu Henner Jill Price Brad Williams
WHAT WE STILL DON’T KNOW
Scenario 1: Studying for Calculus 233 Current hypothesis of memory: Working memory
model Frontal Cortex, Sensory Cortex, Thalamus, Hippocampus,
Amygdala Factors for simulation: Emotion, Attention, Number of
Study Sessions How Short-term becomes Long-term Based on Hebb’s Law
