Parents often think their teenagers tune them out when offered constructive criticism Guess what? They might be right.

Researchers from Harvard University, the University of Pittsburgh and the University of California-Berkeley asked a handful of teens listen to recordings of the teens’ own mothers nagging them. As the teens listened, the researchers also monitored the kids’ brainwaves to see if there were any changes taking place in their little noggins.

The experts found that during and shortly after the recorded scolding, teens showed less activity in regions of the brain associated with self-control and empathy (understanding how other folks might be feeling), along with the expected upswing in negative emotions.

In other words, researchers say, “youth shut down social processing [and] possibly do not think about their parents’ mental states” in the face of nagging. (Wired)
