Most people exhibit some level of ocular prevalence (Ehrenstein, Arnold-Schulz-Gahmen, & Jaschinski, 2005;Erkelens, Muijs, & van Ee, 1996;Haase, 1995;Heinrich, Kromeier, Bach, & Kommerell, 2005;Jaschinski & Schroth, 2008;Kommerell et al, 2003;Sachsenweger, 1958). What we wish to capture by the term ocular prevalence is the "graded quantification of the balance between the eyes" (Kommerell et al, 2003(Kommerell et al, , p. 1397) that is achieved in conditions of fusion with no diplopia; such a quantitative, graded difference in cortical activation has been reported for dominance (Rombouts, Barkhof, Sprenger, Valk, & Scheltens, 1996), at least partly grounded in anatomy and physiology.…”

We present a theory of foveation in normal binocular reading. We consider the pervasive, nontrivial binocular fixation disparities (FDs) observed in reading and relate them to the computational problem of resolving retinal disparities in depth perception. We infer that the right eye's fixation being to the right of the left eye's in reading promotes binocular fusion in challenging conditions. We then show a different (nonfusional) processing advantage for the right eye's fixation being to the left of the left eye's in reading conditions in which binocular fusion is assured, by modeling the combined influence of foveal splitting, contralateral preference, ocular prevalence, and fixation disparity. This synthesis of anatomically grounded research in different aspects of visual processing produces a theory of foveation in reading that matches current data and makes testable predictions.

“…Dies geschieht auch dann, wenn kein Schielen vorliegt und beide Augen einzeln gleichwertig sind. Je nach Gröûe der Stereodisparität, unter der die Objekte dargeboten werden, bezeichnet man das Übergewicht eines Auges als Dominanz oder, nach dem Vorschlag von Sachsenweger [9], als Prävalenz.…”

“…Eine Prüfung auf Prävalenz erlaubt es dagegen, auch eine geringe Bevorzugung eines Auges zu bestimmen [9]. Dabei werden zwei hintereinander stehende Objekte dargeboten, deren Stereodisparität nur wenige Winkelminuten betragen darf, so dass gerade noch keine Doppelbilder auftreten.…”

“…Any perceived misalignment between stereo object and reference object indicates that the perception of the right or left eye has a higher weight, that is, is prevalent when the visual directions of stereo objects have to be estimated (Sachsenweger, 1958). Haase (1995) found that in some subjects ocular prevalence can be different depending on whether the stereo object has a crossed or uncrossed disparity, that is, appears in front of or behind the fixation plane.…”
