Absolute (black) and relative (red) compression indices averaged across subjects (for calculation, see Results). Shaded areas indicating the SD across subjects. In the last 50 ms before saccade onset, relative compression is stronger than absolute compression in the darkness and white line conditions. In contrast, there is no such difference between absolute and relative compression in the ruler condition.
