INSIGHT

Brain Rewiring & Pruning in Adolescence

Adolescence is a period of rapid brain rewiring, influenced by hormones and experiences.
Pruning, the elimination of irrelevant neural connections, is crucial for efficient brain function.

INSIGHT

Social Media's Impact on Identity

Social media exposes adolescents to many idealized and fantasized versions of self.
This complicates identity development as their brains, lacking critical thinking, readily accept these portrayals as real.

ANECDOTE

Transgender Identification and Identity Seeking

Dr. Gill has observed a significant increase in young people identifying as transgender in his practice.
He suggests this might be related to their search for identity and belonging in the digital age.

In the third podcast of this series, “Brain Rot: What Our Screen Are Doing to Our Minds,” host Dr. Karyne Messina, psychologist, psychoanalyst and author talked about the problems that can emerge in Erik Erikson’s Identity versus Identity Diffusion stage of development along with Dr. Harry Gill, a psychiatrist who has a PhD in neuroscience. The two mental health professionals discussed major difficulties they see in their young patients when they are exposed to too much screen time.

For one thing, excessive screen time during this stage of development can have significant effects on pruning which leads to structural changes in the brain. This is a crucial process in adolescent brain development that involves the elimination of unnecessary neural connections to enhance efficiency while optimizing brain functioning.

They also focused on the impact of social media on the formation of identity, a critical part of healthy personality development. Drs. Messina and Gill shared the challenges young people have navigating in the digital age, which can include exposure to people who are inauthentic on social media, role confusion, and addiction to video games. They emphasized the importance of limiting screen time, encouraging adolescents to have real-life experiences versus having mainly on-line relationships while fostering healthy habits to support brain development and overall well-being during this crucial stage of development.

Dr. Messina highlighted the importance of solidifying one’s identity during adolescence or early adulthood, adding that this task can be difficult to achieve later in life if it isn’t developed when searching for a sense of self is a central task of development.

Dr. Gill talked about ways parents can mitigate too much screen time. He suggested that they limit the time their children have access to their screens. He also believes that adolescents should have chores every day which can give them a sense of accomplishment. Watching movies and shows on television as a family was another suggestion he made. He believes that time spent discussing what everyone has seen can provide a sense of understanding that adolescents may not have while fostering a sense of community within the family.
