How Your Brain Finds Your Name in a Crowd

The Cocktail Party Effect: How Your Brain Finds Your Name in a Crowd You're in a loud room, locked into one conversation, certain you've tuned out everything else. Then someone across the room says your name, and you hear it instantly. For decades, this was treated as proof that your brain has a built in radar for your own name. But when researchers actually counted how many people this happens to, the number wasn't close to everyone. And the deeper explanation turns out to have nothing to do with a special ability at all. This video traces the science from Colin Cherry's original 1953 headphone experiments, through Neville Moray's 1959 discovery, to modern brain recordings that reveal what your auditory cortex is actually doing while you think you're tuning something out completely.
