We use eye-tracking as a method to examine how different mathematical representations of the same mathematical object are attended to by students. The results show that there is a meaningful difference in the eye movements between formulas and graphs. This difference can be understood in terms of the cultural and social shaping of human perception, as well as in terms of differences between the symbolic and the graphical registers, as they have been examined in literature.

Abstract
We use eye-tracking as a method to examine how different mathematical representations of the same mathematical object are attended to by students. The results show that there is a meaningful difference in the eye movements between formulas and graphs. This difference can be understood in terms of the cultural and social shaping of human perception, as well as in terms of differences between the symbolic and the graphical registers, as they have been examined in literature.
