Semantic Models
Category Clustering
Forgetting
Ebbinghaus Memorized long lists of nonsense syllables (cew, qoz)
Forgetting
Theories of Forgetting Decay Theory
Interference
Proactive
Retroactive
Forgetting
Variables affecting interference: Meaningfulness of material
Similarity of material
Time between learning and recall
Memory Disorders
Amnesia May be caused by damage to the limbic system
(specifically Hippocampus). Case of HM –
Suffered from: Moderate retrograde amnesia Severe anterograde amnesia
Memory Disorders
Korsakoff’s Syndrome
May suffer both retrograde and anterograde amnesia Case of 59 yr old man
Memory Disorders
Alzheimer’s Disease
Applications: Foraging
Organisms may be less likely to forget information when it is important for survival
Applications: Eyewitness Testimony
Loftus & Palmer
Believed memories were reconstructed each time they are accessed

One is a bun – egg resting on a bun Two is a shoe – shoe kicking an apple Three is a tree – a butter tree Four is a door – coke logo on a door Five is a hive – beehive made of pasta Six is sticks – can of tuna balanced on a stick Seven is heaven – steak with angel wings Eight is a gate – fence gate made of sugar cubes Nine is wine – potato chips floating down a river of wine Ten is a hen – hen sitting on top of lettuce head
