Transient signals per se do not disrupt the flash-lag effect.
Nijhawan's theory rests on the assumption that transient signals compete with predictive signals to generate the visual percept. We describe experiments that show that this assumption is incorrect. Our results are consistent with an alternative theory that proposes that vision is instead postdictive, in that the perception of an event is influenced by occurrences after the event.
