Sunday, 7.30pm, National Geographic This new science series is quite groundbreaking in its interactive gaming design — you really can play along in real time — and it is excellent at pointing out how everyday lack of focus and inattention causes potentially catastrophic misperceptions. The great achievement is that host Jason Silva, pictured, makes finding out about the limits of perception enormously entertaining. In this debut episode, Focus Pocus, Silva and his team concentrate on the relationship between the eye and the brain. A psychological concept known as inattentional blindness causes us to miss things happening right in front of our eyes. Along with the cute games, including one in which female participants remove their tops (do I have your attention now?), there is a good amount of science. For example, the fovea, the part of the eye responsible for sharp central vision, accounts for just 5 per cent of the surface of the eye but 50 per cent of the brain’s visual cortex is devoted to what the fovea delivers, which is why we see what we focus on with laser-like high-definition resolution. The remaining 95 per cent of the eye — used for peripheral vision — is very low resolution, ‘‘ like a mobile phone camera from 1998’’. So, can you trust what you think you see?
