Explainer: What is anxiety?

Schweitzer tested this in a study published in 2015. Her team recruited 44 kids between the ages of 10 and 17. Twenty-six of the volunteers had ADHD. The others had no diagnosed disorders. They served as a control group. All of the kids completed an attention task. Each sat at a computer and viewed rows of arrows. In each row, they had to quickly identify which way the central arrow was pointing. Meanwhile, the kids all wore a device on their ankles. It tracked their motion.

All the best
