| summary | A basic question in visual cognition is how information is combined across separate glances into a stable, continuous percept. Previous explanations have included theories such as integration in a trans-saccadic buffer or storage in short-term visual memory, or, on the contrary, the idea that perception begins anew with each fixation. Converging evidence from primate neurophysiology, human psychophysics and neuroimaging suggest a new explanation for smooth and stable perception. We argue that the intention to make a saccadic eye movement initiates a series of preparations in the brain that lead to a fundamental alteration in visual processing before and after the saccadic eye movement. This theory of "trans-saccadic perception", in contrast to previous hypotheses based on buffers or memory storage, may help to explain how it is possible—despite discrete sensory input and limited memory—that conscious perception across saccades appears stable, predictable and continuous. |
