Lecture Note 5 Chapter 4: Classical Conditioning, Basic Phenomena and Various Complexities


Definition Breakdown

US, Unconditioned
Food, anything that naturally brings out a response
Stimulus
UR, Unconditioned
Salivation, automatic, natural response to the US
Response
NS, Neutral Stimulus Light/Bell, unrelated stimulus that doesn’t lead to a UR (or CR)
CS, Conditioned
Previously NS, after conditioning and several pairings, now elicits CR
Stimulus
CR, Conditioned Salivation because of Light/Bell, not Food.
Response Previously UR, now only coming because of the CS




Acquisition, Extinction and Associated Response Patterns

Acquisition
Process of strengthening a CR (Salivation) through repeated pairings of NS (Bell) to the US (Food).
• A more intense US (Chocolate) produces a stronger and faster conditioning than a less intense
US (Fruits).
• A more intense NS (Loud bell) produces a stronger and faster conditioning than a less intense
one.
• The maximum amount of conditioning that can take place in a particular situation is known as
the asymptote of conditioning
