Monocular asymmetries in visual latency as a function of sighting dominance

The speed of visual processing in the sighting-dominant and nondominant eyes was assessed using a simultaneity procedure in which an auditory target was set to apparently coincide with the onset of a visual stimulus. Under two types of monocular testing, the information from the sighting dominant eye was processed approximately 14 msec faster than the information from the nonsighting eye. These results suggest that the monocular channels are not completely interchangeable, and that response characteristics may vary as a function of sighting dominance.
