The Time Perception in the Flash-Lag Effect

Flash-Lag Effect (FLE) is known as a phenomenon in which a moving stimuli position is perceived with a lag relative to a flashing stimuli when the flash appears physically aligned with the moving one. In previous accounts both the moving object and flashing stimuli are unconditionally believed as something to be recognized. In this study, we conducted several experiments for FLE involved the problem of segregation between figure and ground. We found that interaction between moving objects and flashing stimuli as compatibility and complementarity of figure/ground effectively influences FLE. The results show us one aspect of the temporal perception, so that the subjective segregation between internal (as figure) and external (as ground) recognition would drive the time.
