Continuous flash suppression : ウィキペディア英語版 | Continuous flash suppression Continuous flash suppression (CFS) is an adapted version of the original flash suppression method. In CFS, the first eye is presented with a static stimulus, such as a schematic face, while the second eye is presented with a series of rapidly changing stimuli. The result is the static stimulus becomes consciously repressed by the stimuli presented in the second eye. A variant of CFS to suppress a dynamic stimulus is also reported CFS not only successfully suppresses images, but it strengthens the depth and duration of suppression compared to previous methods, such as flash suppression and binocular rivalry. CFS has the highest magnitude of suppression and allows researchers to increase the suppression time of an image tenfold. Using this method, subjects may report an image presented in their visual field as being invisible for over three minutes. CFS has the longest suppression time compared to other methods. CFS opens the door to studying preconscious processing mechanisms involved in visual perception. == Applications == CFS can be used to measure the salience of an image. Using this application, CFS can assist in determining if emotionally salient faces have a shorter suppression time compared to neutral faces. Significant differences have been shown in suppression duration depending on the images being suppressed. This illustrates how CFS can be used to more accurately measure the varying strength and perceptual influence of individual visual stimuli. Continuous flash suppression is a useful method for psychologists and neuroscientists interested in studying the mechanisms of conscious and nonconscious visual processing. Whereas other visual illusions that render otherwise salient images invisible have their own shortcomings and advantages, continuous flash suppression has a number of advantages for wiping images from conscious vision. It can erase an image presented at the fovea (which usually is much more resistant to perceptual suppression, unlike, for example, crowding), in every trial (unlike binocular rivalry), for a longer duration (>1 sec, unlike backward masking), with an excellent control of timing (unlike binocular rivalry). It has been widely exploited to tackle the scope and limits of unconscious processing.
