Measuring Social Cognition with a Pixar Film

Are screens rewiring kids' brains and creating a generation of depressed teens? After Jonathan Haidt published his mega-bestseller The Anxious Generation, a lot of parents became convinced that they were. But the science tells a more complicated story.

Ava interviews several scientists studying technology's impact on our brains, then takes matters into her own hands. She meets up with Dr. Emma Duerden, Canada Research Chair in Neuroscience and Learning Disorders, to conduct her own experiment: monitoring a teenager's brain activity in real-time while she scrolls through her phone.

What they discover might surprise you.
