Binocular Coordination of the Eyes during Readin

other visual situations [10], but occasionally converged Primates have frontally placed eyes that facilitate pre-cise binocular coordination and orienting. A very preva-lent assumption in the field of eye-movement research is (crossed) (7 % of fixations). Our data clearly show that on a substantial proportion of fixations during reading, the eyes do not provide retinal inputs that correspond perfectly about the point of fixation. Having demonstrated that fixation disparity occurs frequently during reading, this raises a further important theoretical question about how saccade metrics are programmed. We were able to address this questio
