The time course of vertical, horizontal and oblique saccade trajectories: Evidence for greater distractor interference during vertical saccades.
The present study aimed to characterize the effect of a nearby distractor on vertical, horizontal, and oblique saccade curvature under normal saccade preparation times. Consistent with previous findings, longer-latency vertical saccades showed greater curvature away from a distractor than did oblique or horizontal saccades. At short latencies, vertical saccades also showed greater curvature towards the distractor. A neural explanation for why vertical saccades show greater interference from a distractor is theorized.
