| summary | Saccades are very fast movements of the eyes, that bring poorly resolved peripheral input onto the center of the retinas for detailed visual analysis. Crucial for reading and seeing, they have long been thought to be an open window on the mind and the neo-cortex. The underlying assumption, that saccades are aimed at foveating words/objects of (possible) interest, still stands, having survived the no-less-popular visual-saliency account of scene viewing, while remaining central in reading models. During my talk, I will first review behavioral and neural evidence against this long-standing hypothesis. I will then present novel neuro-computational data revealing that mindless visuo-motor principles in the superior colliculus, a midbrain structure involved in saccade programming, can predict where humans move their eyes in a range of tasks, and in particular during sentence reading and the free viewing of natural scenes. I will finally discuss how top-down cognitive processes may intervene on top of default, low-level, visuo-motor mechanisms to influence oculomotor behavior. |
