title: Interaction between saccade and tracking vergence.
abstract: Additivity of saccade and tracking vergence was examined. Binocular eye movements were measured photoelectrically while subjects tracked a target moving smoothly on a radial line with an interpolated step change to a new radial line. Examining the abrupt portions of the two eyes' movements, we found the durations were almost the same for the two eyes, but that there were reliable differences in the magnitudes which were too large to be understood by an additivity hypothesis.
