Continuous flash suppression (CFS), a technique which was developed by Tsuchiya and Koch in 2005, combined the effectiveness of binocular rivalry and flash suppression to minimise the randomness in rivalry during visual perception and suppression. In a typical CFS trial, the participants are shown two contrasting images, one to each eye and the image of greater signal strength will flash at a constant rate (7-10 Hertz). The target image will be shown to the other eye. Unlike Binocular Switch Suppression (BSS), the target image will remain stationary at the same spot on the screen and will not switch nor flash during the presentation period.
