-a visual illusion wherein a flash and a moving object that appear in the same location are perceived to be displaced from one another (MacKay, 1958; Nijhawan, 1994). Several explanations for this simple illusion have been explored in the neuroscience literature.

-The illusion has been tested in many aspects, through the game of baseball, and how flashes may affect the batter's perception of the ball.

- "FlaSh-Lag" was also the name of a relatively well known Console and PC Gamer from the years 1999-2004.
Chris Rock: Wow man did you just see how displaced that object was.

Jim Thome: Nah man, the flash just made you think it was displaced, that's called the Flash-Lag Effect
