1. Classical Conditioning
Pavlov

2. Classical Conditioning
Terms
Neutral Stimulus: a stimulus that does not initially elicit a response
Unconditioned Stimulus (UCS): an event that elects a cretin predictable response without previous training.
Unconditioned Response (UCR): natural reaction to stimulus
Conditioned Stimulus (CS): a once neutral event that elects a given response after a period of training in which it has been paired with an unconditioned stimulus.
Conditioned Response (CR): The learned reaction to a conditioned stimulus.

3. Classical Conditioning helps animals and humans adapt to the environment.
Acquisition of Classical Conditioning
With each paring of CS and UCS the CR is strengthened over time.
This happens gradually over time.
Timing with the CS and the UCS also influences learning.

4. Extinction: The loss of CR to the UCS is not present during the CS.
Generalization
Pavlov found that similar CS gave the same CR.
Example: Used a circle as the CS, when he would show an oval he would get the same response.
Discrimination: The ability to respond differently to different stimuli
Extinction: The loss of CR to the UCS is not present during the CS.
Spontaneous Recovery reoccurring of CR to the CS, but the CR is not as strong as the first times.

Albert not scared of lab rats
Loud bang is used when he sees them
conditioned over time, now associates rats with loud sound (scared)
