THE NEW YORK TIMES: When Mismatched Voices and Lips Make Your Brain Play Tricks
The good news is, the human brain is flexible and efficient. This helps us make sense of the world. But the bad news is, the human brain is flexible and efficient. This means the brain can sometimes make mistakes.
You can watch this tension play out when the brain tries to connect auditory and visual speech. It’s why we may find a poorly dubbed kung fu movie hard to believe, and why we love believing the gibberish in those Bad Lip Reading Videos on YouTube.
“By dubbing speech that is reasonably consistent with the available mouth movements, we can utterly change the meaning of what the original talker was saying,” said John Magnotti, a neuroscientist at Baylor College of Medicine in Texas. “Sometimes we can detect that something is a little off, but the illusion is usually quite compelling.”
