The neutral stimulus is the knock on the door, the CS is also the knock on the door, and the US is the cocaine that Alexis uses. The knocking of the door becomes associated with the cocaine use, leading to a conditioned response of shaking hands and a pounding heart even when there's just a knock on the door.
