Binocular coordination of eye movements during reading
Binocular coordination of the eyes during reading was examined. Fixation disparity greater than one character occurred on 47% of fixations, with the disparity being predominantly uncrossed (39%), though a small proportion of fixations were crossed. The average magnitude of disparity, measured at the end of fixation, was 1.1 characters for all fixations. For the 47% of non-aligned fixations the ...
متن کاملBinocular Coordination of the Eyes during Reading
Saccadic eye movements and fixations are the behavioral means by which we visually sample text during reading. Human oculomotor control is governed by a complex neurophysiological system involving the brain stem, superior colliculus, and several cortical areas. A very widely held belief among researchers investigating primate vision is that the oculomotor system serves to orient the visual axes...
متن کاملBinocular coordination during reading of blurred and nonblurred text.
PURPOSE Reading a text requires vergence angle adjustments, so that the images in the two eyes fall on corresponding retinal areas. Vergence adjustments bring the two retinal images into Panum's fusional area and therefore, small remaining errors or regulations do not lead to double vision. The present study evaluated dynamic and static aspects of the binocular coordination when upcoming text w...
متن کاملBinocular coordination of saccades during reading in strabismic children.
PURPOSE To our knowledge, studies comparing binocular eye movements during reading task in strabismic children are scarce. The goal of our study was to examine binocular coordination of saccades during reading in strabismic children. METHODS Binocular eye movements were recorded by an infrared system (mobile EBT) in 18 strabismic children 6.8 to 16 years old (mean age 10.2 ± 3) who were asked...
متن کاملBinocular Coordination: Reading Stereoscopic Sentences in Depth
The present study employs a stereoscopic manipulation to present sentences in three dimensions to subjects as they read for comprehension. Subjects read sentences with (a) no depth cues, (b) a monocular depth cue that implied the sentence loomed out of the screen (i.e., increasing retinal size), (c) congruent monocular and binocular (retinal disparity) depth cues (i.e., both implied the sentenc...
