Adolescents are increasingly capable of making meaningful contributions to others. Contributing in substantive ways promotes the autonomy, identity, and relationship skills adolescents are developing. This article from Perspectives on Psychological Science looks at the neural and biological foundations of the need to contribute, and how social environments can provide opportunities for young people to help others.

This fact sheet gives an overview of adolescent brain development and explains how access to resources, opportunities, and meaningful relationships during adolescence can build connections within our brains and with the world around us that support us into adulthood.
Brain development during adolescence is fundamentally a story of connections.
Around age 9 or 10, hormonal changes kick off a period of intense learning and development, when brain cells form, strengthen, and streamline connections in response to our experiences more rapidly than in any period of life after early childhood.
Activity increases especially in the brain networks that propel us to explore the world, learn from our mistakes, and connect with others in new ways. In turn, these new experiences prompt our brain cells to connect with other neurons in ways that help us adapt to new events and new information. These neural connections become stronger the more we use them, while unused connections are pruned away, helping the brain become more efficient at acquiring and mastering new skills and new ways of thinking.
This brain-building learning happens through direct experiences in our environments and interactive, responsive relationships—with our families and peers, in our classrooms and neighborhoods, in community activities, and even online. The resources, opportunities, and experiences we as adults provide in and out of school can help young people’s brains build the extensive networks of connections that will manage the complex knowledge and behaviors needed to navigate adulthood.
Learning by Exploring the World Around Us
One of the networks that changes significantly with the increase in hormones and dopamine at the beginning of puberty is the “reward system” in our brain. Heightened activity in this system increases the feeling of reward we get from exploring the world, taking risks, and learning from the results.
Meanwhile, the network of brain regions that make up the “social brain” also changes during adolescence. These changes help us tune into social and emotional cues, like facial expressions or social rejection and approval, and increase our desire to earn respect and contribute to others. It also enables us to learn the nuances of changing social contexts in ways that help prepare us for adult relationships.
The prefrontal cortex (the region of the brain that orchestrates critical thinking and behavioral control) undergoes its most rapid period of development during adolescence. It builds on many other systems within the brain to manage our responses to the flood of new information and intensifying emotions. Engaging with other people and our environment and learning from our successes and our mistakes, known as “action-based learning,” helps shape the prefrontal cortex by strengthening the connections within it and between it and other brain networks. We learn through repeated practice—which includes trying and sometimes failing—what is adaptive and appropriate in different situations and how to guide our behavior accordingly, in ways that equip us to pursue new forward-looking goals.
When adults provide youth with opportunities to try new things, to practice navigating emotions, and to learn from failures along the way, it helps build the brain connections that we all need to grow into healthy, thriving adults.
Policies, Experiences, and Mindsets Shape the Connecting Brain
Although we can continue to learn new skills and behaviors as adults, the adaptability of the brain during adolescence means that these connections are much more likely to form quickly in response to experiences. The extent of these changes make the adolescent years a critical window when investments in the right policies and programs for youth can shape long-term positive development.
Likewise, this makes the adolescent years a time when negative experiences including racism, other forms of discrimination, poverty, or abuse can create steeper hills for young people to climb toward a healthy adulthood. When adults ensure that all young people, especially those who have experienced earlier adversity, have what they need along their journey, they can build the skills and capacities they need to thrive as adults. This includes opportunities to explore and take healthy risks, to connect with and contribute to those around us, to make decisions and learn from the outcomes, to develop a healthy sense of identity, and to rely on support from parents or other caring adults.
Understanding how and why the brain develops during adolescence lets us provide the support young people need to build healthy connections—in their world and within their brains—that will help our youth and our communities thrive.

Lifestyle factors counteract the neurodevelopmental impact of genetic risk for accelerated brain aging in adolescence
A recent study led by Raluca Petrican and colleagues investigated the interplay between positive lifestyle factors (friendships, parental warmth, school engagement, physical exercise, and healthy nutrition) and genetic risk for major depressive disorder, Alzheimer’s disease, anxiety disorders, bipolar disorder, and schizophrenia.
Analyzing data from the Adolescent Brain Cognitive Development (ABCD) Study (a long-term study of brain development and youth health), the researchers found that genetic risk for disorders such as anxiety and depression increased the risk for mental health problems, while positive lifestyle factors decreased the risk for mental health problems later in adolescence. Both genetic vulnerability and positive lifestyle factors were associated with altered development of brain regions involved in cognitive control, emotion regulation, and attention later in adolescence. Importantly, the changes in brain development linked to positive lifestyle factors reduced the risk for psychiatric disorders—especially among adolescents who had experienced high levels of adversity (Biological Psychiatry, March 2024).
Why this is important: This study highlights the protective role of positive experiences on brain and emotional development in adolescence. It suggests that programs that enhance positive lifestyle factors (such as by improving school connectedness) could help protect against stressors and promote mental health, even among young people who have a genetic risk for psychiatric disorders.
The contribution of community service during the transition to adulthood to health in adulthood
In this study, Laura Wray-Lake and colleagues examined changes in community service engagement from adolescence into adulthood (ages 18 to 30) and the impact on adult health outcomes. The researchers analyzed data from over 10,000 participants from a range of high school graduation years (from 1976 to 2000). They tracked changes in participants’ levels of community service from ages 18 to 30, then looked at behavioral, physical, and psychological health outcomes at ages 35 and 40. The results revealed significant associations between community service involvement and adult health outcomes such that adolescents who continued engaging in community service in the transition from adolescence to adulthood reported lower substance use, healthier behaviors, and higher psychological well-being later in life (Journal of Research on Adolescence, February 2024).
Why this is important: This study shows the importance to health and well-being of promoting and supporting civic engagement opportunities as young people transition into adulthood.
Parental involvement affects parent-adolescents brain-to-brain synchrony when experiencing different emotions together: An EEG-based hyperscanning study
In this study, Xinmei Deng and colleagues used a technique called electroencephalograph (EEG) hyperscanning to examine the brain functions underlying shared parent-adolescent experiences by simultaneously recording brain activity in 26 parent-adolescent pairs as they rated their feelings about several 10-second film clips.
They found that in pairs of parents and youth with high parental involvement (where parents show interest, caring, and warmth) there was greater synchronization in brain activity–that is, their brains were responding in similar ways at the same time–when they shared positive emotions. This kind of synchronization between parents and youth is believed to support adolescent social-emotional development, and is based on the strong emotional bonding and connection between the family members. In this context, it suggests that strong bonds with parents can enhance the way parents and adolescents connect emotionally—even on a brain level (Behavioral Brain Research, February 2024).
Why this is important: This study shows one way that parental involvement impacts the dynamics between parents and young people, highlighting the importance of fostering supportive, caring parent-adolescent relationships over the teenage years.
Teachers’ implementation of the Identity Project is associated with increases in U.S. high school students’ ethnic-racial identity exploration
The Identity Project is an eight-session, school-based intervention that provides high school students with strategies and tools to learn about, explore, and reflect on ethnic-racial identity (ERI). The program has been shown to increase in ethnic-racial identity exploration and resolution in ways that support higher self-esteem, lower depressive symptoms, and better grades, among other positive outcomes, when delivered by researchers. In this study, Adriana Umaña-Taylor and her team sought to evaluate the effectiveness of the Identity Project when delivered by teachers themselves. In a group of 180 high school students from diverse backgrounds, the teacher-led Identity Project intervention increased ERI exploration over the course of the program. Further, the positive effects remained when accounting for factors such as ethnic-racial socialization within the family, student and teacher ethnic-racial identity, gender, immigrant status, and ethno-racial background, suggesting that this intervention is effective across diverse adolescent populations (Journal of Youth and Adolescence, February 2024)
Why this is important: These findings demonstrate that teachers, who are uniquely positioned to impact students, can be trained to effectively implement the Identity Project to help youth develop a positive ethnic-racial identity, which is essential to healthy social and emotional development during the adolescent years.
Responsive parental support buffers the link between chronic stress and cardiometabolic risk among adolescents
Exposure to chronic stress from experiences including poverty, bullying, and family turmoil during adolescence can impact mental and physical health–particularly in cardiometabolic issues such type 2 diabetes, heart disease, and stroke in adulthood. In a new study, Phoebe Lam and colleagues investigated a potential protective factor in the association between stress and health in adolescence: the nature and timing of parental support. Using data from 242 adolescents, the researchers found that youth who experienced higher levels of psychological stress over the past 6 months also showed higher levels of cardiometabolic risk (inflammation). Timely parental support—that is, an increase in support such as advice, comfort, and listening received on stressful days—acted as a buffer against the detrimental effects of stress on heart-related health. When adolescents received support from their parents on days when they experienced stress, the link between chronic stress and cardiovascular risk was weakened. Chronic stress was only linked with cardiovascular risk when youth did not receive support in response to days when they experienced stress. (Brain, Behavior, and Immunity, February 2024)
Why this is important: These findings highlight the importance of parental support provided at the time of stressful experiences to prevent the negative physical effects of stress during adolescence. This makes it clear that youth need support from their parents that is attuned to their experiences.
Providing Positive Pathways for Adolescents to Gain Respect
Fact sheet | Education | Community Engagement | Out-of-School Time | Foster Care | Juvenile Justice
This fact sheet provides insights from developmental science about our need to feel respected in adolescence, and how programs and interventions that meet this need can help support positive development.
Adolescence is a time of remarkable opportunity and growth. From about age 10 to age 25, our maturing brains and changing hormones increase our attention to social status and make positive attention feel more rewarding. These changes motivate us to tune into the social world in ways that help us learn skills to navigate adulthood.
Physical, cognitive, and social changes in adolescence combine to make us more sensitive to feelings of status and respect and to where we belong in our social worlds. This sensitivity is developmentally important. It motivates us to pay attention to our social environments in ways that help us learn to adapt to the more complex social demands of adulthood.
It also amplifies the impact of feeling disrespected, excluded, or given messages that we don’t belong—including through experiences of racism, bias, and other forms of discrimination or harassment.
As adolescents, we’re motivated to find a respected place and role among our peers. To ensure youth can channel this motivation in healthy directions, adults need to give young people ample positive pathways to gain respect and approval from the adults and peers around them.
At the beginning of puberty, around 10 to 13 years old, levels of testosterone increase in both boys and girls and heighten our attention to social status. Around the same time, maturational processes in the brain help us understand the perspectives of others in ways that build empathy, but also increase self-consciousness when we think we’re being socially evaluated. Feeling rewarded from positive attention appears to peak in adolescence, motivating us to find ways to earn approval from those around us.
Youth-serving programs that incorporate opportunities to earn respect and status appear to be more effective than others during our adolescent years. Relationships and environments that provide empathy, support, and positive pathways to earn status can improve academic motivation and increase the effectiveness of health interventions aimed at young people.
The flip side of our increased sensitivity to social reward is the pain of being disrespected or socially rejected. Research indicates that when we feel as though we are being excluded by peers, we report greater distress and show greater activity in a brain region associated with higher levels of depression in general.
Experiences that make us feel disrespected or treated as though we don’t belong thus become powerful social threats. The negative effects of racism, discrimination, and other forms of exclusion are amplified when we’re adolescents,—making efforts to eliminate or at least mitigate exposure to racism and bias for youth especially important.
➢ Preliminary evidence suggests that programs that support adolescents’ desire for autonomy and respect are more effective in delivering their messages. For example, one program found that when middle school students felt program facilitators listened to what they had to say and treated them like competent, independent individuals, they showed greater benefits from the program, including reduced number of suspensions and lower pregnancy rates.
➢ Incorporating respect for adolescents’ values and desire for social status into program messaging can be a way to boost program effectiveness. As one example, a healthy eating intervention for eighth graders that respected young people’s agency by replacing lectures with articles exposing deceptive marketing practices of food organizations and conveyed that higher-status (that is, older) students were choosing to eat healthier was effective in reducing unhealthy snacking—and the results persisted for boys even three months after the intervention.
➢ Youth-led participatory action research (YPAR) programs can directly promote adolescents’ sense of agency and their feeling of being respected within their communities. In these programs, youth identify an issue within their school or community, collaborate with researchers to collect data, and use their findings to suggest potential solutions and advocate for change.
➢ Engaging youth as partners, rather than subjects, in policy and program development and evaluation must be undertaken thoughtfully to maximize the benefits that accrue to youth and to the resultant policy or program. Engaging youth as partners helps young people feel like they are being taken seriously and gives them a sense of ownership over developing, evaluating, or improving a policy or program. However, adolescents are keenly aware when their input is not being taken seriously. Therefore, it is essential that offices and organizations that wish to partner with youth prepare in advance to maximize the potential for effective youth engagement while minimizing the potential for tokenism and the reinforcement of youth-adult power imbalances.
