Is curiosity good for us, or should we learn a lesson from what curiosity did to the cat? And why does curiosity drive some people to explore the ends of the earth and beyond, while others just really aren’t very curious at all? We invite a panel of people for whom curiosity is also at the centre of what they do to discuss the psychology of curiosity in front of an audience at the Cheltenham Science Festival in the UK. They are... Tim Peake – astronaut, test pilot and author. His lifelong curiosity took him to live for six months on the International Space station. While he was there he famously ran the London Marathon on a treadmill and he was the first British astronaut to walk in space. Gosia Goclowska - a lecturer in the department of psychology at the University of Bath. She researches some of the more unusual emotions we experience such as curiosity, awe and surprise. And Matthias Gruber - an associate professor of psychology at the University of Cardiff. His research focuses on the neuroscience of curiosity and learning. Presenter: Claudia Hammond
