A bear cub who has a bad experience with a wolf may conclude from that experience that all big furry animals that growl (other than adult bears) should be avoided. On the other hand, the bear cub probably differentiates between the wolf and a mouse. The mouse might be furry, but it is not big and does not growl. Thus, it is not a danger. A child who has been frightened by a dog may generalize and stay away from all dogs. But the child continues to play with his or her stuffed animals, even if they are dogs.
