The Sunday Edition's Michael Enright talks to the world's best-known person with autism — Temple Grandin.

Grandin overcame speech problems early in life and went on to become an author and activist for causes tied to autism and animal welfare. She has a PhD in animal sciences and is an expert and consultant on animal behaviour, and she invented the Hug Machine that helps people with autism-related disorders deal with anxiety. Grandin headlined a 2010 TED Talk in California on understanding autism, entitled The world needs all kinds of minds, and Time magazine has listed her among the world's most influential people.

In her new book, The Autistic Brain - Thinking Across The Spectrum, Grandin draws on her own experience and the latest research to broaden the public's understanding of the challenges faced by people on the autism spectrum, and how to make the most of their unique strengths and abilities.
