Document Summary
Learning = any relatively permanent change in behavior that occurs because of. Classical conditioning: learning associations between 2 stimulus events. Operant (instrumental) conditioning: learning association between behavior and consequences. Unconditioned stimulus (not learned): stimulus elicits reflexive response. Ex: salivation to smell or sight of food. Conditioned stimulus (learned): an initially neutral stimulus that is often paired with the unconditioned stimulus. Ex: salivation to bell (very similar to unconditioned response but not the same. Stimulus generalization: conditioned response appears with similar stimuli. Discrimination: conditioned response only appears with specific stimuli. Ex: rings a bell that is slightly higher in frequency and don"t give the dog food, dog will only respond to the exact bell they heard that is paired with food. Watson was interested in the development of phobias. Watson"s little albert (11 months old) - he liked furry things. Cs: furry thing paired with loud noise.
