Developmental psychology is the scientific study of how and why humans grow, change, and adapt across the course of their lives. Originally concerned with infants and children, the field has expanded to include adolescence, adult development, aging, and the entire lifespan. Developmental psychologists aim to explain how thinking, feeling, and behaviors change throughout life. This field examines change across three major dimensions, which are physical development, cognitive development, and social emotional development. Within these three dimensions are a broad range of topics including motor skills, executive functions, moral understanding, language acquisition, social change, personality, emotional development, self-concept, and identity formation.
Adolescence is a transitional stage of physical and psychological development that generally occurs during the period from puberty to adulthood. Adolescence is usually associated with the teenage years, but its physical, psychological or cultural expressions may begin earlier or end later. Puberty now typically begins during preadolescence, particularly in females. Physical growth and cognitive development can extend past the teens. Age provides only a rough marker of adolescence, and scholars have not agreed upon a precise definition. Some definitions start as early as 10 and end as late as 25 or 26. The World Health Organization definition officially designates an adolescent as someone between the ages of 10 and 19.

Conduct disorder (CD) is a mental disorder diagnosed in childhood or adolescence that presents itself through a repetitive and persistent pattern of behavior that includes theft, lies, physical violence that may lead to destruction, and reckless breaking of rules, in which the basic rights of others or major age-appropriate norms are violated. These behaviors are often referred to as "antisocial behaviors." It is often seen as the precursor to antisocial personality disorder, which by definition cannot be diagnosed until the individual is 18 years old. Conduct disorder may result from parental rejection and neglect and can be treated with family therapy, as well as behavioral modifications and pharmacotherapy. Conduct disorder is estimated to affect 51.1 million people globally as of 2013.
In sociology, a peer group is both a social group and a primary group of people who have similar interests (homophily), age, background, or social status. The members of this group are likely to influence the person's beliefs and behaviour.
In the psychology of self, one's self-concept is a collection of beliefs about oneself. Generally, self-concept embodies the answer to the question "Who am I?".
Erikson's stages of psychosocial development, as articulated in the second half of the 20th century by Erik Erikson in collaboration with Joan Erikson, is a comprehensive psychoanalytic theory that identifies a series of eight stages that a healthy developing individual should pass through from infancy to late adulthood. According to Erikson's theory the results from each stage, whether positive or negative, influences the results of succeeding stages. Erikson published a book called Childhood and Society in 1950 that made his research well known on the eight stages of psychosocial development. Erikson was originally influenced by Sigmund Freud's psychosexual stages of development. He began by working with Freud's theories specifically, but as he began to dive deeper into biopsychosocial development and how other environmental factors affect human development, he soon progressed past Freud's theories and developed his own ideas. Erikson developed different substantial ways to create a theory about lifespan that he theorized about the nature of personality development as it unfolds from birth through old age or death. He argued that the social experience was valuable throughout our life to each stage that can be recognizable by a conflict specifically as we encounter between the psychological needs and the surroundings of the social environment.
Egocentrism is the inability to differentiate between self and other. More specifically, it is the inability to accurately assume or understand any perspective other than one's own. Egocentrism is found across the life span: in infancy, early childhood, adolescence, and adulthood. Although egocentric behaviors are less prominent in adulthood, the existence of some forms of egocentrism in adulthood indicates that overcoming egocentrism may be a lifelong development that never achieves completion. Adults appear to be less egocentric than children because they are faster to correct from an initially egocentric perspective than children, not because they are less likely to initially adopt an egocentric perspective.
Relational aggression, alternative aggression, or relational bullying is a type of aggression in which harm is caused by damaging someone's relationships or social status.
Developmental psychopathology is the study of the development of psychological disorders with a life course perspective. Researchers who work from this perspective emphasize how psychopathology can be understood as normal development gone awry. Developmental psychopathology focuses on both typical and atypical child development in an effort to identify genetic, environmental, and parenting factors that may influence the longitudinal trajectory of psychological well being.
Emerging adulthood, early adulthood or post-adolescence refers to a phase of the life span between late adolescence and early adulthood, as initially proposed by Jeffrey Arnett in a 2000 article from the American Psychologist. It primarily describes people living in developed countries, but it is also experienced by young adults in urban wealthy families in the Global South. The term describes young adults who do not have children, do not live in their own homes, and/or do not have sufficient income to become fully independent. Arnett suggests emerging adulthood is the distinct period between 18 and 29 years of age where young adults become more independent and explore various life possibilities.
The imaginary audience refers to a psychological state where an individual imagines and believes that multitudes of people are enthusiastically listening to or watching them. Though this state is often exhibited in young adolescence, people of any age may harbor a fantasy of an imaginary audience.
Siblings play a unique role in one another's lives that simulates the companionship of parents as well as the influence and assistance of friends. Because siblings often grow up in the same household, they have a large amount of exposure to one another, like other members of the immediate family. However, though a sibling relationship can have both hierarchical and reciprocal elements, this relationship tends to be more egalitarian and symmetrical than with family members of other generations. Furthermore, sibling relationships often reflect the overall condition of cohesiveness within a family.

Ethnic identity development includes the identity formation in an individual's self-categorization in, and psychological attachment to, (an) ethnic group(s). Ethnic identity is characterized as part of one's overarching self-concept and identification. It is distinct from the development of ethnic group identities.
Child Development is a bimonthly peer-reviewed academic journal covering developmental psychology from the fetal period to adolescence. It was established in 1930 and the editor-in-chief is Glenn Roisman. It is published by Wiley-Blackwell on behalf of the Society for Research in Child Development. The journal publishes original contributions on topics in child development from the fetal period through adolescence.
Laurence Steinberg is an American university professor of psychology, specializing in adolescent psychological development.
The dual systems model, also known as the maturational imbalance model, is a theory arising from developmental cognitive neuroscience which posits that increased risk-taking during adolescence is a result of a combination of heightened reward sensitivity and immature impulse control. In other words, the appreciation for the benefits arising from the success of an endeavor is heightened, but the appreciation of the risks of failure lags behind.
Adele Eskeles Gottfried is a professor emerita and psychologist known for her work in the field of intrinsic motivation, giftedness, and academic achievement. Gottfried taught in the department of Educational Psychology at California State University, Northridge, where she was director of Research Enhancement of the Michael D. Eisner College of Education.
Social emotional development represents a specific domain of child development. It is a gradual, integrative process through which children acquire the capacity to understand, experience, express, and manage emotions and to develop meaningful relationships with others. As such, social emotional development encompasses a large range of skills and constructs, including, but not limited to: self-awareness, joint attention, play, theory of mind, self-esteem, emotion regulation, friendships, and identity development.
