Neuroscience finds blinking slows when someone is really listening.

Ever wondered if there's a genuine, physical sign that someone is hanging on your every word? New research from Concordia University in Montreal suggests there is, and it's surprisingly simple: they blink less. Most of us think of blinking as a purely visual function, a quick refresh for the eyes, but this study flips that notion on its head, proposing that our blink rate is a window into cognitive effort.The researchers, led by honors student Pénélope Coupal, equipped 49 adults with special glasses to track their blinks while playing them sentences obscured by background noise. As the volume dropped and listening required more concentration, a clear pattern emerged: a systematic slowing of the blink rate.'We don’t just blink randomly,' Coupal noted, explaining that we blink less when processing salient information, a finding that held true even when visual conditions like lighting were changed. This isn't about judging the frequent blinker in your meeting, however; baseline rates vary wildly from person to person, with some blinking 70 times a minute and others only 10.The key is the individual slowdown, the subtle shift that signals the brain is fully engaged. It’s a fascinating piece of the human puzzle, a quiet, biological confirmation of attention that adds a new layer to our understanding of communication. For anyone who leads, teaches, or simply wants to connect, it’s a reminder that the most telling conversations often happen in the silences between words, written in the language of the body itself.
