I had people in my life who didn't give up on me: my mother, my aunt, my science teacher. I had one-on-one speech therapy. I had a nanny who spent all day playing turn-taking games with me.

Autism is a neurological disorder. It's not caused by bad parenting. It's caused by, you know, abnormal development in the brain. The emotional circuits in the brain are abnormal. And there also are differences in the white matter, which is the brain's computer cables that hook up the different brain departments.

I believe that the best way to create good living conditions for any animal, whether it's a captive animal living in a zoo, a farm animal or a pet, is to base animal welfare programs on the core emotion systems in the brain. My theory is that the environment animals live in should activate their positive emotions as much as possible, and not activate their negative emotions any more than necessary. If we get the animal's emotions rights, we will have fewer problem behaviors... All animals and people have the same core emotion systems in the brain.

I feel very strongly, we've got to give animals a good life. I've worked really hard improving slaughter plants and animal handling and transport. And people have said to me, why don't you work on improving conditions on pig farms? And basically, to be effective on making real change out there on the ground, you can only work on so many things. You know, you get too distributed, you're not effective.

If I did not have my work, I would not have any life.

We breed dogs to be more social than the wolf. There is very interesting research that has been done with a wolf and a domestic dog. If you have a tamed wolf and you have him sit in front of the experimenter or stand in front of his master and his two dishes, one to the right, one to the left – so that the dog or wolf see the food put in the left hand dish but the owner points to the right – the domesticated will go where owner points, whereas the the wolf goes right where he saw the meat thing put. In other words, in a dog social cue from a master can override where he saw the being placed.

Medication should never be considered the only tool for helping a person.
