What is memory?
Chapter 1
What is memory?
Three definitions (Spear & Riccio, 1994)
location where information is kept
thing that holds the contents of experience
e.g., a storehouse, or memory store
e.g., a memory trace or engram
mental process used to acquire (learn),
store, or retrieve (remember) information
Early Memory Research in
Psychology and Neuroscience
• Ebbinghaus (late 1800s)
– nonsense syllables
– basic memory phenomena
• learning curve
– massed vs. spaced/distributed practice
• forgetting curve
• overlearning
• savings
Early Memory Research in
Psychology and Neuroscience
• Lashley (1950)
– engram: neural
of memory
– quantity, not
– memory
distributed all
over cortex
Early Memory Research in
Psychology and Neuroscience
• Hebb (1949)
– two stage process
• neural excitation would reverberate around
connections of neurons
• some of these connections would physically
change and become stronger
– long-term potentiation
