Adolescence is a formative period because it involves significant physical, emotional, and social changes. During this time, teenagers experience firsts in love, friendship, risk-taking, and social interactions, which shape their identity and how they navigate the world. The brain is also optimized for learning and memory during this phase, making experiences more impactful and memorable.
The 'reminiscence bump' refers to the phenomenon where adults recall a disproportionate number of memories from their late teens and early 20s. This period is significant because it is marked by first experiences, which are more distinctive and have a greater impact on identity formation. The brain's enhanced ability to lay down memories during this time also contributes to the vividness of these recollections.
Teenagers take risks not out of recklessness but often for calculated reasons. Risk-taking can be socially advantageous, as it helps them fit in or gain peer approval. Additionally, they are driven by sensation-seeking and a desire to experience new things, which is a natural part of their developmental phase. This behavior is not careless but rather a way to explore boundaries and understand their place in the world.
Social media has a dual impact on teenage body image. On one hand, it exposes teenagers to unrealistic beauty standards and comparisons, which can exacerbate body dissatisfaction and eating disorders. On the other hand, it also provides platforms for body positivity and diverse representation, offering some teenagers a sense of community and acceptance. The overall effect is complex and varies depending on individual experiences.
The paradox of popularity is that being perceived as popular does not necessarily mean being well-liked. Popularity often correlates with social status and visibility, but those who are highly visible may not be genuinely liked by their peers. Research shows that some popular individuals are actively disliked, while others who are genuinely liked may not have high social status.
Peer pressure is often misunderstood because it is rarely about coercion. Instead, teenagers willingly adopt behaviors or attitudes to fit in or gain social approval. The influence of peers is more about mutual reinforcement and shared interests rather than one-sided pressure. This dynamic is a natural part of social development and not necessarily negative.
Overprotective parenting can hinder a teenager's ability to develop independence and autonomy. Adolescence is a time for experimenting with new experiences and learning to navigate the world independently. When parents overly restrict their teenagers, it can lead to frustration, resentment, and a lack of preparedness for adulthood. Balancing safety with allowing freedom is a key challenge for parents.
Lucy Foulkes disagrees with Jonathan Haidt's argument because she believes it oversimplifies the impact of smartphones and social media on mental health. While there is evidence that social media can be harmful for some teenagers, the research is not conclusive, and the effects are not as universally negative as Haidt suggests. Foulkes emphasizes the need for a more nuanced understanding rather than blanket bans.
Teenage romance is often more emotionally intense than adult relationships because teenagers experience love and heartbreak for the first time. They lack the emotional regulation skills of adults and have more mental space to obsess over relationships. This intensity is heightened by the novelty of the experience and the absence of life experience to provide perspective.
Delaying school start times for teenagers faces logistical challenges such as conflicts with parents' work schedules, teachers' childcare arrangements, and concerns about academic performance. A study attempting to delay school start times by an hour failed to recruit schools due to these practical issues, highlighting the difficulty of implementing such changes despite evidence of their benefits for adolescent sleep and health.
Adolescence is the most dramatic and formative period of our lives. Once puberty kicks in and we move to secondary school, our peers take centre stage, and we begin to experience peer pressure and risk-taking. In these pivotal years, adolescents experience sex, love, bullying, friendship, social media and more. According to psychologist Lucy Foulkes, adolescence profoundly shapes who we become as adults, and yet as a period of life, it’s so often dismissed or misunderstood. And even though adults want to protect them, it’s important that as a society we don’t try to prevent teenagers from having the challenging, exhilarating experiences that helps them understand who they are and how to navigate the world.
In November 2024, Foulkes came to Intelligence Squared to share surprising insights from her recent book 'Coming of Age: How Adolescence Shapes Us', gathered from her research as an academic psychologist at the University of Oxford. She will explain why, in contrast to psychologist Jonathan Haidt, she disagrees with blanket bans for smartphones as a solution for improving teen mental health. She will discuss why self-consciousness, risk-taking and sensation-seeking are crucial features of the teenage developmental phase. And she will reveal why being popular can be just as hard as being lonely, and why friendships at this age shape us for life.
Foulkes was joined in conversation by journalist and broadcaster Pandora Sykes.
