Adolescent Psychology: What Makes Teens Different, And How Can Psychology Help?

Updated October 7, 2022 by BetterHelp Editorial Team

Teenagers live in an exhilarating time of transition from childhood to adulthood. This time can be full of exciting discoveries as teens develop their unique personality traits and skills. On the other hand, there are also challenges that accompany the process of becoming an adult. Because teenagers differ fundamentally from children and adults, it’s important to understand them psychologically so you can support them better as they grow.

Adolescence is a time of great change for teens, not to mention everyone involved in their lives. It’s important for teenagers to develop an identity and independence. At the same time, they face growing pressure to be responsible and trustworthy while they grapple with new-to-them issues like sexuality, drug use, and peer relationships. Adolescent psychology seeks to understand teens and help them make the transition from child to adult.

The American Academy of Pediatrics explains that adolescence is a period of fast-paced development in five key areas: moral, social, physical, cognitive, and emotional. To support this development, adolescent psychology focuses on mental health issues for people between the ages of 13 and 19. Adolescent psychologists recognize and help teenagers during this time of growth and transition.

How A Teen’s Mind Works Differently

Adolescent Psychology Can Be Tough To Navigate On Your Own

It’s completely normal to experience difficulties in your relationship with your teenager, especially if they undergo adolescent egocentrism. There are many ways to better understand and connect with your teen so that you can help them cope with the changes they’re experiencing. The American Academy of Child & Adolescent Psychiatry explains that adolescents are more likely to:

  • Be impulsive
  • Misunderstand emotions and social cues
  • Have accidents or physical fights
  • Take risks or make dangerous choices

Development from childhood to adulthood is a complex process. It’s about much more than learning. Teenagers going through this transition think, feel, and behave differently than they do either as children or as adults, as various parts of their brain and hormone production are developing and shifting. These differences can be seen in all areas of development.

Physical/Sexual Development

The physical signs of adolescence are usually obvious. People start growing pubic hair during this time. They also get taller, with girls generally reaching full height by age 16 and boys generally reaching full height by age 18. Secondary sexual characteristics will begin to develop; for some, that may mean having periods and developing breasts. For others, that may mean developing facial hair and deepening voices.

From the perspective of adolescent psychology, brain development during this period is particularly important. The areas of the brain that allow teens to control behaviors and emotions experience significant development during this phase, as do the areas where risk and reward are calculated. Teenagers also gain the ability to think more efficiently due to changes in the myelin and synapses of the brain.

All of these physical changes affect the way adolescents think and behave. Many develop sexual awareness and may become sexually active. As long as they are healthy, their bodies are likely to be stronger and more coordinated than ever before, allowing them to excel in sports. Teens can have many opportunities as well as challenges related to their physical development. Understanding adolescent psychology can help them make sense of the physical changes they’re going through so that they can deal with them positively.

Cognitive Development

In addition to physical development, adolescence brings new ways of thinking. As teenagers develop cognitively, they gain the ability to think abstractly. Imagination and complex reasoning develop exponentially during this phase. Because of this, teenagers gain the ability to understand abstract concepts found in advanced math and begin to think more about ideas like spirituality and love.

Abstract thinking also makes teens greater risk-takers because they may feel invincible to harm. As they mature, they should eventually develop stronger reasoning skills and can think things through logically. They develop the ability to judge things for themselves, so they can think through the possible consequences of an action in advance.

This cognitive development doesn’t happen in a flash. In early adolescence, children mainly use their newfound abstract reasoning for schoolwork and at home. They start expressing their views about what activities they want to engage in and choose their own goals. They see short-term consequences but they can’t always envision the long term.

In middle adolescence, their thinking becomes more complex. They can imagine what their future will be like, but they have a hard time applying those thoughts to their decision-making process. They also question things more. In late adolescence, teens begin to think outside themselves in a new way. They may think more about what’s happening in the world and the major challenges facing society. They may also become concerned with career choices and what to do after they leave home.

Emotional Development

During this often-tumultuous time, teens look to their peers for emotional support. They may begin to have more conflicts with their parents until late adolescence, when they may become closer to them again.

It’s normal at this time for adolescents to want and need privacy. They’re concerned about the way they look and may develop body image issues. As they reach late adolescence, they’ll likely become more confident in themselves and their beliefs. They may seek out sensory experiences and become easily sexually aroused. During late adolescence, they often begin to have better control over their emotions. Much of adolescent psychology deals with teaching teens how to understand and manage their emotions.

Moral Development

Teens develop their sense of morality during adolescence as well. They are transitioning from the authority and social order stage of development, in which they were focused on fixed rules. As they mature, they begin to analyze social contracts and relationships. They may become concerned with doing what is mutually beneficial and doing what is morally right, even if it isn’t legally right. As they grow into adulthood, their moral focus may shift again as they begin to think of “right” and “wrong” as universal concepts that apply across legal systems and cultures.

Adolescent Identity

Along with other facets of cognitive, emotional, and social development, teens develop their own unique identities during this stage. From early to late adolescence, their thinking is affected by adolescent egocentrism, though less and less as they mature. Three features of adolescent egocentrism involve:

  • Self-absorption: their focus is almost entirely on themselves.
  • Personal fable: they see themselves as unique and special.
  • Imaginary audience: they think others are focused on them, noting everything about them including what they say and what they do.

Helping Adolescents

It’s normal for teenagers to encounter struggles amid all of this change. Adolescent psychology deals with important issues that can have a lasting impact on the life of a teen. Some of these include independence, sexuality, drug use, and peer relationships. As they go through this exciting and challenging phase of development, teens may need help from adolescent psychologists so they can work through and resolve these issues in positive ways. As they go through these experiences, they typically learn how to handle difficult situations and therefore become more independent.


Teens need to become independent to become fully functioning adults. As they develop, they can gain the skills to become autonomous. To do this, they must:

  • Explore their identity and develop a stable sense of who they are.
  • Become more aware of themselves and their thoughts and behaviors.
  • Set and reach goals.

Parents can play a role in helping adolescents gain independence by allowing them to make their own choices and live with the consequences. At the same time, teens need the love and respect of their parents or guardians. They need support from parents or guardians who are confident in their abilities, but they also need guidance without strict control. This can be challenging for parents, especially in areas like sexuality, drug use, and friend groups.


Teen sexual development involves many different tasks. Teenagers benefit greatly from learning to understand and feel okay with the changes that are going on in their bodies, and from learning how to make decisions about what they do with their bodies, including sex. Along the way, they need to discover their sexual identity and learn how to have healthy sexual relationships. While about 50 percent of teens have sex before the age of 18, even teens who are not engaging in sexual activities benefit from developing sexual awareness and relationship skills as they transition to adulthood.

Drug Use

Most teens will be faced with the possibility of using drugs and alcohol. It’s important for them to be aware of the consequences, but drug education is most effective when focused on the actual risks of using drugs rather than outrageous scare stories. Otherwise, it can be wholly ineffective because teens have the cognitive ability to recognize the difference between concern and attempts to control them. For many parents, the key to discouraging drug use is to communicate the potential dangers and consequences well.

Peer Relationships

Peer relationships are extremely important to teenagers. They learn how to build relationships as well as how to end them. Plus, they deal with competition from peers, both socially and academically. Child and adolescent psychology can provide them with tools for social interactions with peers and teach them to nurture relationships that are important to them.

Abnormal Child And Adolescent Psychology

Abnormal child and adolescent psychology deal with teens who have mental health problems. Some common mental health issues that teens deal with include:

  • Depression
  • Body dysmorphic disorder
  • Eating disorders
  • Anxiety disorders
  • Mood disorders
  • Schizophrenia
  • ADHD
  • Autism

If a child is suspected to have any of these conditions, the support of a mental health professional is recommended. Dealing with these problems skillfully during adolescence not only helps them get through the turbulent teen years, but also gives them a chance for a better future as they learn self-understanding and healthy coping mechanisms that they can carry into adulthood.

Sometimes a parent or primary caregiver is not the right person to help an adolescent through this season of life. Some of the things that teenagers often value, such as privacy and anonymity, can be found through an online counselor. BetterHelp offers therapists and mental health professionals who specialize in adolescent psychology. These caring individuals can provide a safe place for your teenager to learn new skills to help them cope with life changes. They can also help you as a parent if you’re struggling during this time. Our team has helped multiple teens and parents of teens navigate communication along with the issues detailed in this article; in fact, BetterHelp has devoted the platform TeenCounseling to serve people aged 13 to 19 years old.

“I have been working with Carolyn for 6 months now, and have tremendously benefited from her counseling as I support my daughter for Anorexia. This allows me to use correct words with her, and watch by own behavior with her so I am supporting her in a healthy manner, and not enabling her illness further. Additionally, my own stress has been very difficult as I watch my sweet daughter suffer, so I had been in need of finding coping skills for myself. Carolyn’s expertise, her very compassionate but clear guidelines and feedback to me have made be more confident and capable in dealing with this difficult illness.
