For whatever reason, at some point or another, you may have decided to say the same word over and over again. It might have been the word strange. That’s strange. Strange. Sssttt-Rrraaa-Nnn-Ggg-Eee.

While this may have felt like a sort of cognitive processing glitch, some scientists, such as cognitive neuroscientist David Huber from the University of Massachusetts, believe this experience gives us an important insight into how our minds perceive the external world.
