Very well done NPR story about 9 year old girl named Isabelle with Williams Syndrome. I had never heard about this rare genetic disorder that causes a range of problems including causing children to love people and have no fear of strangers. At first you may think this is no big deal but as you listen to the personal story you realize how big a life problem this could be.
Minor critique, I would have liked a bit of context on how rare it is (how does it compare to Autism or ADHD for example) and some sense of whether Isabella is typical of kids with this or if she is higher or lower functioning. This bit of info would help teachers, doctors and others who may encounter kids like this.
While they probably did not have it, I have met a few kids lately who do seem strangely friendly to me, a strange man in the pool or playground. One girl at the water park recently was talking my ear off and hanging out with me and my baby for a long time and I had no clue where her parents were.
This story makes me think about this specific aspect of human development and whether or not the variation you see in shyness, fear of strangers, or outgoing behavior is somehow related to the same system that causes this problem. There are some kids who are super anxious of talking to new people and fearful of strangers, maybe this is due to some problem with their limbic system and their oxytocin levels. It is amazing to think about how so much of human behavior is not only related to how you are raised but about the chemical soup your brain is stewing in.
This compainion story gets into this issue
in more depth. This is scary: "Zak (professor) began spraying oxytocin up the noses of college students to see if the hormone would change the way they interacted with strangers. It did. Squirt oxytocin up the nose of a college kid, and he's 80 percent more likely to distribute his own money to perfect strangers. "
