Abstract

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