Ars Technica: Continuous flash suppression is a visual perception phenomenon in which a repeating flash of light presented to one eye completely suppresses the brain’s ability to perceive an image presented to the other eye. Gary Lupyan of the University of Wisconsin–Madison and his colleagues have now found that when a person first hears a word that describes the image, the brain is primed and the suppression effect is itself often overwhelmed. Lupyan says that because the flash suppression occurs at a low level, there is no subconscious processing of the image that the verbal prompting draws on. That suggests that hearing the word directly affects the visual processing system. Other research has shown a similar relationship between perception and cognition, but visual processing and language are usually studied independent of each other. What that means in the larger understanding of language and perception in humans is still open to debate and, hopefully, further research.
