CrowdScience

CrowdScience listener Jeroen finds it hard to remember people's faces - and he wants to know why. He wonders if it's to do with getting older or if there are other reasons behind it.

Presenter Caroline Steel has the same problem and is keen to find an answer too.

She meets Professor Zaira Cattaneo, a neuroscientist who has researched the condition of face blindness, known as prosopagnosia. Zaira has discovered which parts of the brain are engaged in facial recognition and explains the factors that contribute to the condition.

Caroline travels to Bournemouth in the UK to meet researcher Professor Sarah Bate, who assesses Caroline's ability to recognise faces.

And she compares notes with fellow CrowdScience presenter Marnie Chesterton, who also has difficulty remembering faces. Around three per cent of the population have the condition. Could there be a reason why more than a third of CrowdScience presenters experience face blindness?
