I 53
Seeing/Focus/Frith: we see only a surprisingly small section of a scene. (E.g. I 52).
---
I 54
Change blindness/Rensink/Frith: a changed detail attracts only by chance our attention.
---
I 56
Brain: our brain knows that the scene as a whole is not blurred (even if the eye is only fixed on a small section)
Experience/Frith: thesis: therefore, our experience of a detailed visual world is rather an experience of different possibilities than what is already represented in our brain.

I 132
Seeing/Experience/Brain/Helmholtz/Frith: E.g. Someone moves his eye with his finger: the world seems to move jerkily from one side to the other.
Solution: The brain has no experience with this kind of action. But with normal eye movements.
Solution: it is our brain that sends the signals to the eye muscles. This allows to predict exactly how the visual will change.
Learning: once again the brain learns important things about the world through prediction (?).
Prediction/Prognosis/Brain: the brain can use the prediction to make the world appear stable even though the image jumps wildly back and forth on our retina.
