Dr. Larry J. Young, author of The Chemistry Between Us and researcher at Emory, joins Andy to discuss the hormones that drive humans (and animals!) to form deep bonds with each other. Plus, how increasing your teen’s oxytocin could be the key to creating a sociable adult.

Full show notes

It can sometimes be worrying when our teenagers struggle to form bonds with other teens. As our kids get older, we want to make sure they’re able to form positive relationships with others so that they can move successfully through college, thrive in the workplace, become president of the United States… or whatever great things they plan to do!

So what can you do when your teenager is struggling to connect or even choosing to isolate themselves, playing video games all day instead? You might feel like something’s gone wrong, or that you’ve made a mistake as a parent. Don’t fear, however. With a little scientific exploration, we can get to the bottom of how teens connect with one another, so that you can guide your teen towards better social habits.

Our guest today, Dr. Larry Young, is an expert on the hormones that help teens forge and maintain relationships. He’s a professor, leading researcher on social behaviors, and the author of The Chemistry Between Us: Love, Sex, and the Science of Attraction. He’s here today to delve into the science behind teenagers’ interactions, and how parents can help their kids find social success.

In order to examine how teenage brain chemistry affects their ability to socialize, Larry began by studying a subject he knew well: wild animals

Survival Strategies

Dr. Young grew up on a farm, and was always interested in what we could learn about friendships, relationships, and sexual behavior from the behaviors of different animals. In his research, he found that there was a lot of variation amongst different species--and that the same was true for humans.

To aid his research on relationship and bonding hormones in humans, Larry spent nearly 25 years studying the mating patterns of voles: small, stocky rodents similar to field mice. He found that unlike many species of animals (and similarly to humans), prairie voles are socially monogamous creatures, who form lasting pairs and raise their young together.

For these prairie voles, monogamy provides extra protection and resources for their litter by having both parents around. This ensures that offspring will have a safer upbringing, allowing them to get a head start when it comes to surviving in the world.

However, Richard was surprised to find in his research that another, almost identical species of voles adopts the exact opposite strategy. Instead of forming monogamous pairings, males of this species tend to be loners and bachelors, while females often abandon their offspring as early as two months old. For these voles, leaving youngsters to fend for themselves is the chosen strategy to raise a successful litter. Despite being very similar to prairie voles, these voles have their own way of raising kids that doesn’t follow the same rules.

This goes to show that not all of us adopt the same survival strategies--and that’s ok. There’s variability in what brings about a successful, happy individual. Some teens are more likely to fend for themselves, while others are more inclined to find a partner or a pack. Similarly, no parenting strategy is perfect, and each of us approaches situations with different perspectives. In the episode, Larry speaks further about how variability presents itself in the wild and amongst humans .

Although we’re all different, we all have similar hormones in our brains, informing us on how to attract mates, take care of others and ensure our safety. Learning about these hormones can help us understand our teen’s behavior, and nudge them towards being a little more social. Larry focuses on two of these hormones: Oxytocin and Vasopressin.

How Oxytocin Helps Teens Socialize Successfully

When it comes to forming bonds, one of our brain’s most active hormones is oxytocin. This powerful chemical is what is released in a mother’s brain when she gives birth, the hormone that causes her to care deeply for her child. Throughout the child’s youth, when she engages in nurturing behavior, she releases oxytocin into both her own brain and the brain of her child.

Larry explains how kids who may have received lots of skin to skin contact, or heard their parents’ voice consistently throughout childhood have higher levels of oxytocin in their brains, even into adulthood. According to Larry’s research, teens who have these increased oxytocin levels may be more socially capable and confident. For example, politicians are known to have brains with high levels of oxytocin, allowing them to be charming and likeable.

For those with lower oxytocin levels, communicating and creating strong relationships can be a little more difficult. Richard discusses how those with low oxytocin have a harder time reading others’ emotions and may not always have an easy time socializing. When a teen appears to have lower oxytocin levels, this is not necessarily the parents’ fault, Dr. Young emphasizes--often times this is out of anyone’s control. It could be caused by small cumulative, cultural factors, or just occur naturally in a person’s brain.

If you feel that maybe your teen isn’t experiencing the highest levels of oxytocin, then Dr. Young shares some tips in the episode to help your teenager boost their social abilities to ensure that they’re socially capable and comfortable as they approach adulthood.

Now that we’ve discussed oxytocin, let’s look at another significant hormone developing in your adolescent: vasopressin.

Vasopressin and Effects

If oxytocin allows individuals to become more nurturing, Vasopressin is the hormone that causes them to become protective. It’s particularly high in males, as it’s linked to testosterone. It’s the behavioral motivation for males to guard property, children or even their partners.

Has your teenage son seem to have developed tendencies that border on violence or aggressiveness? Does he seem a little more possessive than he used to be, getting ticked off when you go in his room or move his things? That’s likely due to increased levels of vasopressin.

Richard expresses how important this hormone is to the process of mating; it’s key to bonding females and males together. Although it’s stronger in men, it’s active in females as well, and it's part of what makes people fall in love. That means that if your teenager has begun dating and seems inseparable from their new “friend”.... it’s the hormones at work.

Richard talks more specifically about the effects of vasopressin in the episode. Although it may cause a sudden shift in teenage behavior, it’s a perfectly normal part of puberty. By understanding the hormones at work in your teen’s brain, you’ll be more equipped to handle them at their worst, so you can raise them to be their best.

In the Episode…

Beyond hormones, there’s a lot we can learn from Larry about how teens form relationships and understand one another. His research spans many different topics, and he’s been in the field of behavioral science research for quite a while! We talk about:

Whether girls are truly attracted to “bad boys”
How fetishes can develop over time
Why monogamy is an evolutionary adaptation…
