Maybe there are subsets or ranges within the skill type? There is so much we don't know about the brain and learning.
Off topic, but the toast story reminded me that my older sis and I used to bite round cookies into the shapes of little people, then we'd gobble them in one bit and go "ahhh!!" like they were screaming. My mother says now, some of the things we used to do, that she was glad a child psychologist never observed us (we gave our dolls diseases and used to put them in the hospital.) We turned out really well though, not a violent bone in anyone's body.
