Behaviorism
School of psychology that defines psychology as the scientific study as observable and measurable behavior.
John B. Watson
Founding father of behaviorism.
Learning
A relatively permanent change in behavior due to experience or practice.

Ivan Pavlov
Russian psychologist, studying salvation in dogs and digestion.
Pavlov's classical conditioning experiment
Process: Tubes surgically inserted in the cheeks of a dog, and collects amount with food presented. Accident: Noticed that dogs would salivate when food was simply brought into the room.
Pavlov's second version of the classical conditioning experiment.
Used a bell or metronome, and meat products to show dog would salivate at the sound of the bell.

Classical(Pavlovian) Conditioning
Simple form of learning where one stimulus calls forth the response usually called forth by another stimulus; ASSOCIATION.
Stimulus
Anything that produces a reaction from a person or animal.
Response
The reaction to a stimulus. Ex: Scream, cry.

Unconditioned Stimulus (UCS)
Causes an automatic response; NOT LEARNED (meat in Pavlov's study).
Unconditioned Response (UCR)
Automatic response; occurs naturally (salvation)
Neutral Stimulus
Nothing to do with the UCS or UCR; causes a sensory response but does not produce the response being tested (bell).
Conditioned stimulus (CS)
Formerly the neutral stimulus; has acquired the ability to elicit a response that was previously elicited by the UCS. (bell)
Conditioned Response (CR)
LEARNED; ELICITED BY THE CS but not the same as the UCR (strength is different, what produces it is different).
