Final answer:
John Watson's famous baby Albert experiment demonstrated the classical conditioning principle of stimulus generalization.
Step-by-step explanation:
John Watson's famous baby Albert experiment demonstrated the classical conditioning principle of stimulus generalization.
During the experiment, Little Albert was conditioned to fear a white rat by pairing its presentation with a loud sound that frightened him. As a result, Little Albert developed a fear response not only to the white rat but also to other furry objects, such as a rabbit, a furry coat, and a Santa Claus mask.
This experiment showed that a conditioned response can generalize to similar stimuli even if they were not initially paired with the unconditioned stimulus, in this case, the loud sound.
