Figure Legend: From: Crowding and eccentricity determine reading rate Journal of Vision. 2007;7(2):20. doi:10.1167/7.2.20 Figure Legend: Displace the word. Reading rate as a function of the horizontal position (number of letters to the right of fixation) on which a four-letter word is centered. We measure threshold reading rates for unordered four-letter words. The line is the fit by Equation 6. The horizontal gray bars represent the uncrowded span u estimated by the model fit. u is 8.1 at vertical eccentricity 0°, 7.4 at −5°, and 5.3 at −20°. Observer KAT.
