Topic: orientation change detection

Saccades enable primates to sample their visual environments at high resolution. Yet, even before the saccade occurs, visual discrimination sensitivity increases at the saccade target location. Does this benefit occur in all scenarios? To address this question, we designed a dual-task paradigm involving visual change detection. On each trial, participants (n=10) prepared and executed a saccade to one (cued) of four grating locations while concurrently localizing a change in grating orientation that immediately preceded the saccade. Surprisingly, we found no improvement in orientation change de
