Localization of shapes: eye movements and perception compared

The localization of spatially extended objects is thought to be based on the computation of a default reference position, such as the center of gravity. This position can serve as the goal point for a saccade, a locus for fixation, or the reference for perceptual localization. We compared perceptual and saccadic localization for non-convex shapes where the center of gravity (COG) was located ou...

Fixational eye movements and perception

http://dx.doi.org/10.1016/j.visres.2015.12.001 0042-6989/Published by Elsevier Ltd. Visual perception is a fundamentally active process. In humans and other foveated species, many functions, including acuity, are not uniform across the visual field, but deteriorate with increasing distance from the foveola, the tiny rod-free region of the retina where cones are most densely packed. This strateg...

Eye movements reset visual perception.

Human vision uses saccadic eye movements to rapidly shift the sensitive foveal portion of our retina to objects of interest. For vision to function properly amidst these ballistic eye movements, a mechanism is needed to extract discrete percepts on each fixation from the continuous stream of neural activity that spans fixations. The speed of visual parsing is crucial because human behaviors ran...
