Grand averaged plots of eye trajectories and SPEM velocities.

The left graph shows the grand averaged eye displacement for the two experimental conditions, Smooth (red) and Noisy (blue) target motion; the target path is shown as a dotted black line. The presence of the occluder is indicated by the vertical grey lines. When the target emerges from its second pass through the occluder, the ERF is recorded (black bar). The amplitudes of the traces have been normalized to ± 1. The right graph shows the grand averaged SPEM velocities, with saccades (defined as movements faster than ± 35°/sec) removed from the velocity data prior to averaging.
