Generalization: tendency for stimuli similar to CS to elicit similar responses Helped separate psychology from early 19 th century association with philosophy – making psychology a science by basing findings on observation.

UCS UCR NS No UCR NS + UCS UCR CS CR *UCS = unconditioned stimulus UCR = unconditioned response NS = neutral stimulus CS = conditioned stimulus CR = conditioned response More examples of classical conditioning: Cancer patients and nausea Drug = nausea Waiting Room + Drug = nausea Waiting Room = nausea Getting rid of a conditioned response: Extinction: Diminishing of a CR In classical conditioning, when a UCS does not follow a CS Ex: dogs, the bell goes off, but the food does not follow, dogs response will become weaker and weaker and may eventually stop. The more extreme the CR, the longer it will take to be extinct....
