We’ve all been there. Stuck in our own heads, fixated on a two-minute conversation from three days ago. We replay it over and over. I shouldn’t have snapped at Dad. He was always so patient when I was growing up. We get stuck. The voice in our heads goes from an ally to a vicious nag, just looping uselessly over the same things, again and again and again.
Ethan Kross, an experimental psychologist and neuroscientist at the University of Michigan, wants to teach us how to control the voices in our heads. Not the voices of mental illness, mind you, just the little voice we all have, cheerily (or naggingly) narrating our lives as we go about our days.
