Independent Vergence and Saccade Adaptation: (a) Inter-ocular divergence around the time of a saccade following the dichoptic target step, averaged across observers and across the first 10 (green) and last 10 (red) trials. Grey shaded region represents the approximate period of the saccade. Red and green shaded regions are 68% bootstrapped confidence intervals of the median inter-ocular divergence as a function of time from saccade onset. Filled lines are the median logistic functions fitted to the data. Asterisks represent the point at which the vergence response is initiated. (b) Latency and (c) amplitude of the vergence response from saccade onset as a function of adaptation trial number. Data are the median for six observers. Solid blue lines are the best fitting exponential decay (latency) and linear (amplitude) functions passing through the data.
