Teens’ brains begin to understand their mother’s voice at age 13, study finds

Ever feel like you’re talking to a brick wall when trying to communicate with your kids?

Well a new study suggests there may be some science to it, after finding that teen brains start tuning in to their mother’s voice around the age of 13.

That’s because they no longer find it ‘uniquely rewarding’, the researchers said, and instead tune more into unfamiliar voices.

The study, conducted by the Stanford School of Medicine, used functional MRI brain scans to track how teens begin to separate from their parents.

It suggests that when It sounds like your teen isn’t listening to you, it’s not that they don’t want to clean their room or finish their homework – their brain isn’t recording your voice the way they did. did in the pre-teen years.

“Just as an infant knows how to tune into its mother’s voice, an adolescent knows how to tune into novel voices,” said lead study author Daniel Abrams, a clinical associate professor of psychiatry and behavioral sciences.

‘As a teen, you don’t know you’re doing this. You are just you: you have friends and new partners and you want to spend time with them.

‘Your brain is becoming more sensitive and attracted to these unfamiliar sounds.’

In some ways, the brains of teens are more receptive to all voices — including those of their mothers — than the brains of children under 12, the researchers found, a finding that may reflect a wide variety of social cues in teens. increases interest in

But in adolescent brains, reward circuits and brain centers that prioritize important stimuli are more activated by unfamiliar sounds than by their mothers.

Researchers said the brain’s shift to new sounds is one aspect of healthy maturation.

“A child becomes independent at some point, and this is precipitated by an underlying biological signal,” said study senior author Vinod Menon, professor of psychiatry and behavioral sciences.

‘That’s what we uncovered: it’s a signal that helps teens engage with the world and make connections that allow them to be able to socialize outside of their families.’

The Stanford team previously found that in the brains of children under the age of 12, hearing a mother’s voice triggers an explosion of unique responses.

A study published in 2016 showed that babies can recognize their mother’s voice with extremely high accuracy, and that particular sounds trigger not only the auditory-processing regions of the brain, but many areas from unfamiliar voices. does not trigger.

It contains the reward center, emotion-processing area, visual processing center and brain networks that decide which incoming information is the main one.

“The mother’s voice is the sound source that teaches young children about the social-emotional world and language development,” said Percy Mistry, co-lead author and research scholar in Psychiatry and Behavioral Sciences.

‘Fetus in the womb can recognize their mother’s voice before they are born, yet with adolescents – even if they have spent more time with this sound source than babies – their brains are turning away from it in favor of voices. Have never even heard of.’

The new study, built on a previous study, combines data from adolescents aged 13 to 16.5 years.

The researchers recorded the teen’s mothers saying three nonsense words that lasted less than a second.

The use of nonsensical words ensures that participants will not respond to the meaning or emotional content of the words.

Two women unfamiliar with the study subjects were recorded saying the same nonsense word.

Each adolescent participant listened to several repetitions of nonsense-word recordings by their mother and unfamiliar women, presented in random order, and recognized when they heard their mother.

Like young children, teens correctly recognized their mother’s voice more than 97 percent of the time.

The teens were then placed in a magnetic resonance imaging scanner, where they listened to the voice recordings again.

They also listened to brief recordings of household sounds, such as the dishwasher running, allowing the researchers to see how the brain reacts to the sounds in comparison to other non-social sounds.

The researchers found that, among adolescents, all voices elicited greater activation in several brain regions than did younger children: the ‘voice-selective superior temporal sulcus’, an auditory processing area; ‘Critical processing areas’ that filter what information is important; and the ‘posterior cingulate cortex’, which is involved in aspects of autobiographical and social memory.

Brain responses to sounds increased with age of teens—in fact, the relationship was so strong that researchers could use voice-response information in brain scans of teens to predict how old they were.

The fact is that the brain is so used to sounds – just ask anyone who has felt an emotional shock after hearing a friend or family member’s voice over a long period of time, the researchers said.

“The voices in our environment are these incredibly rewarding sound sources that allow us to feel connected, included, part of a community and family,” Abrams said.

‘Voice is what really connects us.’

A major change occurs in the social interactions of children during adolescence.

“Our findings suggest that this process is implicated in neurobiological changes,” Menon said.

‘When teens seem to revolt by not listening to their parents, it is because they are wired to pay more attention to sounds outside their home.’

This research is published in the Journal of Neuroscience.

Teens really ignore you! Study shows teens spend 12% less time looking at the face of the person they’re talking to than adults

A study published last year showed that teens actually ignore you, spending less time looking at your face when you’re talking to them.

A team led by the University of Kent recorded three groups of volunteers aged 10-19, 20-40 and 60-80 in real-world social interaction situations.

The situations involved them interacting face-to-face and navigating the environment, with eye-tracking glasses used to monitor their interactions.

The findings showed that adolescents pay less attention to social cues in real-world interactions than adults.

They found that teens and older adults spend 12 percent less time looking at the face of someone they’re talking to, and two percent less time looking at people in a navigation task than young adults aged 20 to 40. spend less time.

The researchers explained that facial expression, tone of voice and gestures of others are an important element of social interaction.

The findings suggest that social attention undergoes age-related changes that, according to the researchers, have potential implications for how successfully we can interpret social interactions in daily life and throughout our lives.

The authors wrote, ‘Interpreting facial expressions, tone of voice, and expressions of others is an important element of social interaction.

‘These skills allow us to make rapid inferences about the mental states of others, such as their intentions, feelings, desires and beliefs.’

Successful social interaction fosters perspective-taking and empathy, along with other essential social skills, and plays an important role in enhancing our well-being.

The research, led by PhD student Martina De Lillo with Professor Heather Ferguson, was the first to examine how social attention is allocated during adolescence and whether it differs from adulthood.
