Many authors include this experiment conducted by Watson in introductory textbooks because it is one of the most fundamental experiments done that helps us understand classical conditioning. It is also the easiest to understand as the subject was none other than a human being. The Little Albert experiment explains how we can grow fearful of less frightening objects when paired with an uncomfortable response caused by something else more fearful. In Albert's case he was fine with the rat before Watson had produced the loud sound. Then after that every time he would come near the rat he would start crying therefore eliciting a phobia of rats and even other furry objects.
