What drives looking?

What factors drives infant looking? Discuss both low-level (e.g., contrast, color) and high-level (e.g., interest, recognition) factors. How could you test how surprise impacts infants attention? How could you test whether recognition impacts infants attention? How can you resolve the apparent conflict if both appear to yield increases in looking time?

Design and describe an experiment to explore these questions. You can design and experiment that focuses on just one, or more than one. Aim for approximately SINGLE SPACE  one page. Sketches welcome, as always.
