Adolescents do not simply become steadily more and more like adults with time. Rather, adolescents alternate between acting like adults and acting like children. As adolescents develop, they gradually spend more time behaving as adults and less time behaving as children.
During adolescence, people develop a sense of who they are and learn to form intimate relationships with people who are not members of the family.

Intellectual and Behavioral Development in Adolescents
In early adolescence, a child begins to develop the capacity for abstract, logical thought. This increased sophistication leads to an enhanced awareness of self and the ability to reflect on one’s own being. Because of the many noticeable physical changes of adolescence, this self-awareness often turns into self-consciousness, with an accompanying feeling of awkwardness. The adolescent also has a preoccupation with physical appearance and attractiveness and a heightened sensitivity to differences from peers.
In mid adolescence, the weight of making decisions about a future career gets increasingly heavy, and most adolescents do not have a clearly defined goal, although they gradually realize their areas of interest and talent. Parents must be aware of the adolescent’s capabilities and help the adolescent set realistic goals. Parents also must be prepared to identify roadblocks to learning, such as learning disabilities Definition of Developmental Disorders Developmental disorders are better called neurodevelopmental disorders.

Adolescents also apply their new reflective capabilities to moral issues. Preadolescents understand right and wrong as fixed and absolute. Older adolescents often question standards of behavior and may reject traditions—to the consternation of parents. Ideally, this reflection culminates in the development and internalization of the adolescent’s own moral code.
Many adolescents begin to engage in risky behaviors, such as fast driving. Many adolescents begin to experiment sexually, and some may engage in risky sexual practices. Some adolescents may engage in illegal activities, such as theft and alcohol and illicit drug use. Experts speculate that these behaviors occur in part because adolescents tend to overestimate their own abilities in preparation for leaving home. Studies of the nervous system also have shown that the parts of the brain that suppress impulses are not fully mature until early adulthood.
Emotional Development in Adolescents
During adolescence, the regions of the brain that control emotions develop and mature. This phase is characterized by seemingly spontaneous outbursts that can be challenging for parents and teachers who often receive the brunt. Adolescents gradually learn to suppress inappropriate thoughts and actions and replace them with goal-oriented behaviors.
A typical area of conflict is the adolescent’s normal desire to seek more freedom, which clashes with the parents’ instincts to protect their children from harm. Frustration caused by trying to grow in many directions is common. Communication can be challenging as parents and adolescents renegotiate their relationship. All of these challenges are accentuated when families face other stresses or parents have emotional difficulties of their own because adolescents continue to need parenting. Doctors can help open lines of communication by offering adolescents and parents sensible, practical, supportive advice.
Social and Psychologic Development in Adolescents
The family is the center of social life for children. During adolescence, the peer group begins to replace the family as the child’s primary social focus. Peer groups are often established because of distinctions in dress, appearance, attitudes, hobbies, interests, and other characteristics that may seem profound or trivial to outsiders. Initially, peer groups are usually same-sex but typically become mixed later in adolescence. These groups assume an importance to adolescents because they provide validation for the adolescent’s tentative choices and support in stressful situations.
Adolescents who find themselves without a peer group may develop intense feelings of being different and alienated. Although these feelings usually do not have permanent effects, they may worsen the potential for dysfunctional or antisocial behavior. At the other extreme, the peer group can assume too much importance, also resulting in antisocial behavior.

Parents can have a strong positive influence on their children by setting a good example (such as using alcohol in moderation and avoiding use of illicit drugs), sharing their values, and setting high expectations regarding staying away from illicit drugs.

Development of Sexuality and Gender in Adolescents

The timing and speed with which these... read more (puberty) typically is accompanied by an interest in sexual anatomy, which may be a source of anxiety. As adolescents mature emotionally and sexually, they may begin to engage in sexual behaviors. Masturbation is common among girls and nearly universal among boys. Sexual experimentation with a partner often begins as touching or petting and may progress to oral, vaginal, or anal sex. By late adolescence, sexuality shifts from experimentation to being an expression of intimacy and sharing.
Doctors should provide appropriate advice on safer sex practices as part of routine health care and should screen all sexually active adolescents for sexually transmitted infections.
As adolescents navigate their sexuality, they may also begin to question their sexual identity and gender identity.
Sex refers to a person's anatomy: male, female, or not clearly male or female (ambiguous genitals Symptoms

There are many different sexual identities, such as heterosexual (attraction to the opposite gender), homosexual (attraction to the same gender), bisexual (attraction to both genders), and asexual (attraction to neither gender).

Transgender is any gender identity in which people feel that the sex they were assigned at birth does not match their gender identity.
Gender expression is how people present themselves in public in terms of gender. It includes the way people dress, speak, wear their hair—in fact everything that people say and do that indicates masculinity or femininity.
Gender identity starts to develop early on, but may evolve over time. In some children and adolescents, the sex they were assigned at birth does not match their gender identity. This mismatch can cause considerable mental distress known as gender dysphoria Gender Incongruence and Gender Dysphoria Gender incongruence is a marked and persistent experience of incompatibility between a person's gender identity and the gender expected based on sex at birth.

Some adolescents are uncertain about sexual orientation. They may be unsure of what they are feeling, but it is common for adolescents to be attracted to or have sexual thoughts about people of the same sex and people of the opposite sex. However, many adolescents who explore homosexual or bisexual relationships ultimately do not continue to be interested in same-sex relationships, whereas others never develop interest in opposite-sex relationships.

Adolescents who have a strong sense of their homosexual or bisexual identity may “come out” to their close friends or family members.
Some adolescents may face challenges as their sexual and gender identities develop. They may fear their sexual identity or gender identity will not be accepted by family or peers. Such pressure (especially during a time when social acceptance is critically important) can cause severe stress. Fear of abandonment by parents, sometimes real, may lead to dishonest or at least incomplete communication between adolescents and their parents. These adolescents can also be taunted and bullied Bullying Bullying is a form of youth violence in which repeated verbal, emotional, physical, or psychologic attacks are done to dominate or humiliate.

The emotional development of these adolescents is best helped by supportive friends and family members.
Few elements of the human experience combine physical, intellectual, and emotional aspects as thoroughly as sexuality and all the feelings that go along with it. Helping adolescents put sexuality and gender identity into a healthy context is extremely important. Parents should share their values and expectations openly with their adolescents but be receptive and supportive as their child’s sexual and gender identities develop.
