I have misplaced my iPhone. I search for it with my mind’s eye. In thoughts I trace my route through the house. Some people, such as Oliver Sacks, lack a mind’s eye. This is called aphantasia. At the other extreme are people with a super mind’s eye.
London taxi drivers know every street in London, as well as all the restaurants, post offices, shops and more. In our brain there is an ingenious GPS. And this GPS is integrated with our life history and emotions. Try doing that with a navigator!
You walk down a street and nearly bump into someone; you look at their face and in a fraction of a second you know who it is. It does not really matter if you see them in profile or full face. And one can do this with thousands of faces; a clever trick of our brains. How do we recognise faces?
