Example of results of Experiment 1 obtained from a single participant.

<p>Perception task: psychometric curves for the proportion of the responses that judged the reference bar appeared on the right side of the final target position as a function of the relative reference bar position to the final target position. Vertical lines indicate the PSE of each internal motion condition. Saccade task: saccade landing positions (relative to the final target positions) for two delay conditions (0 and 1.8s). Vertical lines indicate the mean horizontal landing positions of each internal motion condition.
