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
