The Secret Life of Screens: AI, Emotion, and the Teen Brain [With Dr Jacqueline Nesi]

Teens are forming emotional bonds — not just online, but with AI companions. In this episode, Dr Justin Coulson talks with Brown University psychologist Dr Jacqueline Nesi, author of Techno Sapiens, about the fast-growing world of AI “friendships” and what they mean for kids’ mental health. They also unpack Jackie’s latest research revealing how often teens check their phones — and how it’s shaping their moods. It’s a must-listen for parents navigating the blurred lines between connection, distraction, and dependence in the digital age. KEY POINTS 72% of teens have used an AI companion; over half use one regularly. AI chatbots are designed to keep kids engaged — often prioritising screen time over wellbeing. For some vulnerable kids, AI chats can feel like friendship or therapy — but they aren’t replacements for real connection. Australia’s new social-media age-limit laws may help, but implementation and design flaws remain. Teens check their phones an average of 112 times a day — once every 10 minutes! Frequent phone checking is linked with greater emotional ups and downs. Teens who are less mindful tend to reach for their phones more after bad days — using screens as emotional regulation tools. What matters most: how kids use technology and who they are, not just how much. QUOTE OF THE EPISODE “The effects of smartphones on mood and wellbeing are complicated — it’s not that phones are simply bad, it’s about who’s using them and how.” RESOURCES MENTIONED Techno Sapiens – Dr Jacqueline Nesi’s Substack Tech Without Stress – Resources for parents Happy Families – More parenting resources ACTION STEPS FOR PARENTS Ask your kids how they use AI or chatbots — listen before you lecture.
