The Illusory Flash (VIDEO)

Caption

This audio and visual illusion illustrates the phenomenon of postdiction: when a stimulus presented later in time affects the perception of a stimulus presented earlier. In this case, a rapid series of beeps and flashes leads the brain to believe it perceived a flash when in fact there was not one.
