Vision and Eye Movements

Eye movements are a measurable characteristic that can be used to learn more about cognitive and visual processing. Saccades, smooth pursuit movements, vergence movements, and vestibulo-ocular movements are the four primary types of eye movements. Although eye movements have been studied for a long time, it is only in the last few decades that their quantification has led to significant insights into psychological processes such as reading, visual search, and scene perception. Our eyes move every 200-350 milliseconds while reading, examining a visual array for a target, or simply staring at a new scene. These eye movements are used to direct the fovea (the high-resolution region of the retina that covers 2 degrees at the center of the visual field) to a point of interest so that it can process it more thoroughly.
