Final answer:
John Watson's demonstration of classical conditioning with Baby Albert involved pairing a loud noise (UCS) with a white rat (CS) to elicit a fear response (CR) in Albert, which later generalized to similar furry objects.
Step-by-step explanation:
John Watson and Classical Conditioning
John Watson's experiments with Baby Albert are classic demonstrations of classical conditioning. Watson and his graduate student, Rosalie Rayner, used this method to show how a neutral stimulus, when paired with an unconditioned stimulus, can evoke a conditioned response. In the case of Little Albert, the unconditioned stimulus (UCS) was the loud noise, and the unconditioned response (UCR) was fear from the noise. The conditioned stimulus (CS) became the white rat after it was repeatedly paired with the loud noise. Soon, the mere presence of the white rat evoked the conditioned response (CR), which was fear. Later, stimulus generalization occurred when Little Albert started to fear similar furry objects.
