Dallas Campbell delves into the Horizon archive to discover how our understanding of intelligence has transformed over the last century. From early caveman thinkers to computers doing the thinking for us, he discovers the best ways of testing how clever we are - and enhancing it.
It is a feeling we all know - the moment when a light goes on in your head. In a sudden flash of inspiration, a new idea is born. Today, scientists are using some unusual techniques to try to work out how these moments of creativity - whether big, small or life-changing - come about. They have devised a series of puzzles and brainteasers to draw out our creative behaviour, while the very latest neuroimaging technology means researchers can actually peer inside our brains and witness the creative spark as it happens. What they are discovering could have the power to make every one of us more creative.
Normal people can become monsters, given the right situation. That’s the standard narrative of the Stanford Prison Experiment, one of the most famous psychological experiments of all time. But what if the cause of its participants’ cruel behavior wasn’t what we’ve always been told?
A child's brain is a magnificent engine for learning. A child learns to crawl, then walk, run and explore.

Comedian and impressionist Rory Bremner is on a personal mission to uncover the science of ADHD (attention deficit hyperactivity disorder), a condition which he has suspected he has. In this film, Rory learns about the science of ADHD, goes for a diagnosis and tries the drug methylphenidate (also known as Ritalin) for the first time - just before walking on stage. Around three per cent of the adult population suffer from ADHD (and five per cent of children), yet many people remain sceptical of its existence, blaming it on naughty children or bad parenting.
