Monotropism. That’s a big word isn’t it? Well for one of our hosts it’s been a massive one.

Jamie says it’s changed his life, so we are joined by one of the first people to theorise it, Dr Wenn Lawson, to explain just what it is and why it could help autistic people and those around them to live happier lives.

It could help explain how our minds focus so well on one thing, why we have such intense interests, and why switching between tasks can be painful.

Speaking of special interests, we also hear from some of our listeners about theirs and how their interests have helped them.

Presented by Robyn Steward and Jamie Knight. Produced by Drew Hyndman and Edited by Clare Fordham.
