Open the camera app on your phone and start recording a video. Place the screen right in front of your eyes and try to use the live footage as a viewfinder. Tricky, right? The shapes, colors, and motion in the video are jarring. Scientists say this exercise is a close approximation of the messy visual data that our eyes constantly bombard our brain with. So how exactly do we see without feeling dizzy or nauseated?
In a new paper published last month in the journal Science Advances, researchers from the University of Aberdeen and the University of California, Berkeley describe a "previously unknown visual illusion" that helps us smooth out what we see over time.
"Instead of analysing every single visual snapshot, we perceive in a given moment an average of what we saw in the past 15 seconds," the authors note in a piece published in The Conversation, a website where scientists routinely detail their latest work. "So, by pulling together objects to appear more similar to each other, our brain tricks us into perceiving a stable environment. Living 'in the past' can explain why we do not notice subtle changes that occur over time."
