abstract：:To explore visual space, we make saccades, vergence, and, most frequently, combined saccade-vergence eye movements. The initiation of saccades is well studied, while that of vergence is less explored. Saccade latency is influenced by the fixation task: when the target appears simultaneously with the offset of the fixa...
