I believe the correct answer is fear can be learned via classical conditioning, and that fear can be generalized.
During this experiment, Watson presented Albert with a white mouse and a scary sound, so every time Albert saw a mouse, he was scared by the sound. Over time, he learned to be afraid of the mouse because he was expecting to be scared by the sound, even though the sound may not come. Thus, he learned to be afraid, and the fear was generalized not only to the mouse, but to anything white.
