Reading with two eyes - about binocular coordination and advantages

Dr. phil. Stefanie Jainta, FHNW Olten, Switzerland


Abstract. Reading is a sophisticated, uniquely human skill which requires the simultaneous operation of visual, oculomotor, attentional and linguistic processes. During normal reading, vergence eye movements establish a stable vertical alignment as a pre-requisite for efficient horizontal motor fusional responses (i.e. vergence movements), which in turn serve to maximise correspondence in retinal activation between the two eyes. This facilitates the sensory fusion of the two inputs and provides a stable and single percept of the text. Sensory fusion can take place over a small range of fixation disparities (i.e. slight alignment errors of the eyes), which are (as other vergence adjustments) sensitive to quality aspects of the text. The present talk will characterize typical binocular coordination during reading and show that binocular fusion is a valuable pre-requisite over which further visual and lexical processes can work most efficiently: binocular vision provides clear advantages for reading which extent to lexical processing of the just read text. Thus, the complex interplay between the human visual system and the language processing system seams crucial for effective reading and the impacts of such evidence will be discussed.
