      abstract     = {The flash-lag effect (FLE) occurs when a flash's position
                      seems to be delayed relative to a continuously moving
                      object, even though both are physically aligned. Although
                      several studies have demonstrated that reduced attention
                      increases FLE magnitude, the precise mechanism underlying
                      these attention-dependent effects remains elusive. In this
                      study, we investigated the influence of visual attention on
                      the FLE by manipulating the level of attention allocated to
                      multiple stimuli moving simultaneously in different
                      locations. Participants were cued to either focus on one
                      moving stimulus or split their attention among two, three,
                      or four moving stimuli presented in different quadrants. We
                      measured trial-wise FLE to explore potential changes in the
                      magnitude of perceived displacement and its trial-to-trial
                      variability under different attention conditions. Our
                      results reveal that FLE magnitudes were significantly
                      greater when attention was divided among multiple stimuli
                      compared with when attention was focused on a single
                      stimulus, suggesting that divided attention considerably
                      augments the perceptual illusion. However, FLE variability,
                      measured as the coefficient of variation, did not differ
                      between conditions, indicating that the consistency of the
                      illusion is unaffected by divided attention. We discuss the
                      interpretations and implications of our findings in the
                      context of widely accepted explanations of the FLE within a
                      dynamic environment.},
