Binocular coordination during scanning of simple dot stimuli

Abstract

We examined the influence of a variety of visual factors on binocular coordination<br/>during saccadic orienting. Some experimental conditions placed similar demands on the<br/>oculomotor system as those that occur during reading, but in the absence of linguistic<br/>processing. We examined whether saccade target extent, preceding saccade magnitude,<br/>preceding saccade direction, and parafoveal availability of saccade target influenced fixation<br/>disparity. Disparities similar in magnitude and frequency to those obtained in previous<br/>binocular reading experiments occurred. Saccade magnitude had a robust influence upon<br/>fixation disparities. The results are very similar to those obtained in investigations of<br/>binocular coordination during reading, and indicate that similar patterns occur during<br/>reading-like eye scanning behaviour, in the absence of linguistic processing
