Do you ever find yourself going about your daily business when suddenly an unpleasant thought pops into your head? These are known as intrusive thoughts. The majority of us experience them without any ill effects. However, for some people they can be highly distressing.

In this episode we catch up with Dr Scott Cairney, a senior lecturer in psychology at the University of York.
