title: Saccade trajectory under simultaneous inhibition for two locations.
abstract: A saccade trajectory often curves away from the location of a non-target stimulus that appears before saccade execution. Spatial inhibition may prevent the saccade from moving toward the non-target stimulus. However, little is known about how simultaneous inhibition for multiple locations affects saccade trajectories. In this study, we examined the effects from two inhibited locations on saccade trajectories. The results show that the saccade trajectories depend on the inhibited locations, and the effect of inhibiting two locations on the trajectory was a summation of the effect of inhibiting each location. A simulation study using the initial interference model also suggests that the effect of each inhibition was summed up to modulate the initial saccade direction.
