Now produces a conditioned response o Extinction  The conditioned stimulus is presented over and over again without the unconditioned stimulus. Eventually the conditioned response will disappear  EX: Ring bell without giving dog food, dog will eventually stop salivating at sound of bell o Spontaneous response  Reappearance of a previously extinguished response o Generalization  Things similar to the conditioned stimulus will elicit the conditioned response associated with it  Phone ring that sounds like bell will make dog salivate o Discrimination  Conditioned response occurs to one stimulus but not to other stimuli  Opposite of generalization  Are organisms able to learn certain info? o Different species have evolved in different environments o Some responses may be easier to learn for a particular species  Can emotion be conditioned? o John B.
