Ivan Pavlov’s Experiment • Originally interested in physiology • Studying effect saliva had on digestion • Noticed dogs began to salivate upon seeing experimenter (even without food)
Example:Ice cube offered (S) Dog comes running (R) Stimulus Response Any action that comes from a stimulus. Anything that causes some kind of reaction.
Unconditioned Response to stimulus is natural and automatic. Initial Stage: Unconditioned Stimulus, Unconditioned Response Example:Ice cube offered (US) Dog comes running (UR)
Neutral Stimulus • Stimulus that has no effect to illicit a response • Specific conditions are necessary • An association must be formed Sound of Ice Machine (NS) Ice Cube offered (US) Dog comes running (UR)
Conditioned Stimulus • An association is made between the neutral stimulus and the unconditioned response • Not a firm tie yet; acts as a hint Sound of Ice Machine (CS) Ice Cube offered (US) Dog comes running (UR)
Conditioned Response • Conditioned stimulus now causes a response on its own • Same response, but now in reaction to conditioned stimulus Sound of Ice Machine (CS) Dog comes running (CR)
Emotional Conditioning • John Watson • In charge of lab rats • Got them to do amazing things • Realized it was only through conditioning • Suggested that deep emotions in humans are just learned experiences
Little Albert • 11 month old Albert • Watson gave him a white rat to play with • Made a loud sound to startle Albert and make him cry • Albert soon was scared of the white rat
Identifying the Pieces • Unconditioned Stimulus: • Loud noise • Unconditioned Response: • Fear of loud noise • Neutral Stimulus: • Rat • Conditioned Stimulus: • Rat • Conditioned Stimulus: • Fear of rat
Extension • Stimulus Generalization: response spreads from one specific stimulus to other similar ones • Albert became afraid of white bunnies and other things that resembled the rat. • Extinction: association created through conditioning disappears • When my dogs don’t go on walks for a while, they forget to sit before crossing the street • Spontaneous Recovery: sudden reappearance of an extinguished response
