| summary | The visual world appears stable and continuous, even though the actual input to our visual brain is constantly changing : interrupted by blinks, smeared by eye and head movements, and shifted by saccades. One of the classic questions about visual perception is how a stable visual percept arises in the face of this highly variable and discontinuous input. I will focus on the case of saccades and the shifts of the retinal location of objects that they cause. I will ask what mechanisms match the various retinal locations of an object across a saccade, to give rise to a unified and stable percept. There have been several theoretical proposals as to how this matching process occurs : remapping, object-based accounts, post-saccadic visual search, priori belief in a stable world, etc. I will review these proposals and give some examples of experimental work addressing the question of trans-saccadic correspondence. |
