WebWhen looking at a visual stimulus, the eyes make continuous and rapid movements known as saccades. With durations of roughly 150–200 milliseconds for planning and execution (Muir & Richardson, 2005), a saccade directs attention to the visual target and during which information processing is restrained (Pan et al., 2004; Rayner, 1998). WebJust as saccades have proven a good model for studying visual-to-motor processes, they have been equally important for understanding motor-to-visual processes. Saccades permit rapid relocation of the fovea, but an attendant visual artifact is the sudden displacement of the entire scene across the retina.

WebMar 15, 2024 · During the active visual exploration of the world rapid eye movements, so-called saccades, shift the visual image across the human retina. Although these high-speed shifts introduce considerable amounts of intra-saccadic motion smear, our perceptual experience is oblivious to it – a phenomenon termed saccadic omission. Webedges and reconstructing the visual world from that information. Physiological nystagmus is the only type of movement which does not have a selective function. However, it is a necessary part of the visual system because without it, our eyes will not be able to detect anything. 2.1.2. Saccadic Movements Saccadic movements are very rapid, ballistic
