Why do friendships formed during adolescence seem to be particularly significant?

Adolescent friendships are significant because this is a time when peer relationships become a focal point due to brain development. The social brain and reward center, such as the ventral striatum, become more active, increasing the value and enjoyment of social interactions.

How does the brain's reward center influence adolescent friendships?

The brain's reward center, specifically the ventral striatum, activates enjoyment when hanging out with friends. This activation motivates adolescents to spend more time with their peers, leading to stronger bonds and more intimate friendships.

What is the 'Theory of Mind' and how does it contribute to the depth of adolescent friendships?

Theory of Mind is the ability to understand others' emotions, thoughts, motivations, and perspectives, recognizing they may differ from one's own. As this ability matures during adolescence, it allows for deeper connections and more intimate friendships, as teens can better understand their friends' viewpoints.

How does the social brain develop during adolescence?

The social brain, which includes various regions responsible for social cognition and interaction, shows increased connectivity during adolescence. This enhanced connectivity allows teens to better understand their friends' perspectives, leading to deeper and more meaningful connections.

What is 'interpersonal synchrony' and how does it relate to friendships?

Interpersonal synchrony is the coordination of actions, emotions, physiology, and thoughts between individuals. It is evident in how friends may walk at the same pace or finish each other's sentences. This synchrony contributes to the feeling of being closely connected and is a sign of a strong bond between friends.

At what age do babies begin to develop Theory of Mind?

Babies begin to develop Theory of Mind around 18 months of age, starting to understand that others may have different perceptions and knowledge than their own.

How does the concept of 'being there for someone' exemplify the strength of a friendship?

The concept of 'being there for someone' during tough times, such as after a breakup, exemplifies the strength of a friendship by showing emotional support, empathy, and the reliability of the friend, which are key components of a strong bond.

Why might a person feel that their actual best friend surpasses an 'ideal' friend they could imagine?

A real best friend might surpass an imagined 'ideal' friend because real relationships are dynamic and multifaceted, involving shared history, genuine emotional connections, and the ability to grow together, which can't be replicated in a hypothetical construct.

How do teenage friendships differ from those in childhood?

Teenage friendships differ from childhood friendships in terms of intimacy and complexity. As adolescents, the social brain and Theory of Mind develop further, allowing for deeper emotional connections and a better understanding of friends' perspectives.

What role does the brain's development during adolescence play in the formation of close friendships?

The brain's development during adolescence plays a crucial role in the formation of close friendships by enhancing the social brain's connectivity and the activation of the reward center, which increases the value and enjoyment of peer interactions.

Can you explain the term 'social reorientation' as it pertains to adolescent friendships?

Social reorientation refers to the shift in focus from family to peer relationships during adolescence. This is when teenagers start spending more time with friends than with their parents, driven by changes in the brain's reward system and the desire for social interaction.

Transcripts

Friendships can hold an exceptional place in our life stories.

What is it about these connections that make them so unique?

Before we dive into the science, let’s first observe one in action.

If I could somehow design a best friend, you know,

put together all the ideal qualities of my perfect match,

that person would pale in comparison to Priya.

She can turn any situation into a good time—

chemistry lab, band practice.

What I’m trying to say is I never laugh harder than when I’m with Priya.

And she’s always there for me.

Like last year after I got dumped by Te— you know what?

I don’t even want to mention their name.

It felt like my whole world was crashing down.

But as soon as I told Priya, boom, she was at my door.

I was a wreck, but she sat there with me and listened.

We’re always on the same page;

it’s as if we can read each other’s minds!

And we can talk for hours— about anything.

I know my mom would say she has the phone bills to prove it.

If it seems like friendships formed in adolescence are particularly special,

that’s because they are.

Early childhood, adolescent, and adult friendships

all manifest a little differently

in part because the brain works in different ways at those stages of life.

Adolescence is a unique time when peer relationships take focus,

and thanks to the developing brain,

there are changes in the way you value, understand, and connect to friends.

Teenage friends can seem attached at the hip.

Scientists describe adolescence as a social reorientation

as teenagers begin to spend as much or more time

with their friends than with their parents.

This drive to hang with pals may be due to changes in the brain’s reward center,

known as the ventral striatum.

Its activation makes hanging out with others enjoyable

and motivates you to spend more time with them.

Neuroimaging studies show that this region is highly reactive

during your teenage years,

which may explain why adolescents seem to place a higher value

on social interactions than children or adults.

Teenage friendships can also feel more intimate

than the friendships of your childhood.

This deeper connection is possible thanks to improvements

in what scientists call Theory of Mind.

Theory of Mind is the ability to understand others’ emotions,

thoughts, motivations, and points of view,

and to realize that they may be different from your own.

While it may seem intuitive,

this ability hinges on the careful coordination of various brain regions,

sometimes referred to as the social brain.

Babies begin to develop Theory of Mind around 18 months or so.

Before that, it’s thought they believe that everyone perceives and knows

exactly what they know.

It was once considered to be fully developed by age five,

but scientists now know that Theory of Mind

continues to improve and mature well into your teenage years and beyond.

Likewise, regions within the social brain show increased connectivity

during adolescence compared with childhood.

As a result, teens can better understand their friend’s perspectives,

allowing for deeper connections to flourish.

In the closest friendships,

it can almost feel as if you’re metaphysically connected—

two bodies and minds, perfectly in sync.

And there is science to this!

Your ability to connect with others somewhat depends

on the coordination of actions, emotions, physiology, and thoughts.

This is what psychologists call interpersonal synchrony.

You first show signs of the ability to sync with others as infants—

synchronizing movements and babbling with your parents.

As you get older and spend more time outside the home,

you increasingly show this synchrony with your peers.

For example, imagine walking down the street with a friend.

Often without consciously thinking,

you stroll at the same pace and follow the same path.

You and your best friend may not be only on the same page,

but also scientifically, in step.
