Nice article to remind us that no matter how mature the teen seems to be in your care or even your own children they still have a developing brain.
From the article-
‘"Thinking strategies change with age," said Sarah-Jayne Blakemore of the University College London Institute of Cognitive Neuroscience. "As you get older you use more or less the same brain network to make decisions about your actions as you did when you were a teenager, but the crucial difference is that the distribution of that brain activity shifts from the back of the brain (when you are a teenager) to the front (when you are an adult)."
Adults were also much faster at figuring out how their actions would affect themselves and other people.
"We think that a teenager's judgment of what they would do in a given situation is driven by the simple question: 'What would I do?'" Blakemore said. "Adults, on the other hand, ask: 'What would I do, given how I would feel and given how the people around me would feel as a result of my actions?'"
