Like our social media feeds, our brains are constantly uploading rich, visual stimuli. But instead of seeing the latest image in real time, we actually see earlier versions because our brain’s refresh time is about 15 seconds, according to new UC Berkeley research.
The findings, appearing today, Jan. 12, in the journal Science Advances, add to a growing body of research about the mechanism behind the “continuity field,” a function of perception in which our brain merges what we see on a constant basis to give us a sense of visual stability.
“If our brains were always updating in real time, the world would be a jittery place with constant fluctuations in shadow, light and movement, and we’d feel like we were hallucinating all the time,” said study senior author David Whitney, a UC Berkeley professor of psychology, neuroscience and vision science.
