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.
In sociology, socialization is the process of internalizing the norms and ideologies of society. Socialization encompasses both learning and teaching and is thus "the means by which social and cultural continuity are attained".
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 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 30. 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", and is often seen as the precursor to antisocial personality disorder; however, the latter, 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.
Granville Stanley Hall was an American psychologist and educator who earned the first doctorate in psychology awarded in the United States of America at Harvard College in the nineteenth century. His interests focused on human life span development and evolutionary theory. Hall was the first president of the American Psychological Association and the first president of Clark University. A 2002 survey by Review of General Psychology ranked Hall as the 72nd most cited psychologist of the 20th century, in a tie with Lewis Terman.
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.
Egocentrism refers to difficulty differentiating between self and other. More specifically, it is difficulty in accurately perceiving and understanding perspectives 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.
Claus Offe is a German political sociologist of Marxist orientation.
Paul B. Baltes was a German psychologist whose broad scientific agenda was devoted to establishing and promoting the life-span orientation of human development. He was also a theorist in the field of the psychology of aging. He has been described by American Psychologist as one of the most influential developmental psychologists.
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 wealthy urban 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 20 and 29 years of age where young adults become more independent and explore various life possibilities.

Religious identity is a specific type of identity formation. Particularly, it is the sense of group membership to a religion and the importance of this group membership as it pertains to one's self-concept. Religious identity is not necessarily the same as religiousness or religiosity. Although these three terms share a commonality, religiousness and religiosity refer to both the value of religious group membership as well as participation in religious events. Religious identity, on the other hand, refers specifically to religious group membership regardless of religious activity or participation.
Crowds are large groups of adolescents defined by their shared image and reputation. Crowd membership is externally imposed and not a direct consequence of interaction with other members of the crowd.
Laurence Steinberg is an American university professor of psychology, specializing in adolescent psychological development.
Child development in Africa addresses the variables and social changes that occur in African children from infancy through adolescence. Three complementary lines of scholarship have sought to generate knowledge about child development in Africa, specifically rooted in endogenous, African ways of knowing: analysis of traditional proverbs, theory-building, and documentation of parental ethno-theories. The first approach has examined the indigenous formulations of child development and socialisation values embedded in African languages and oral traditions. Several collections of proverbs have been published in different African languages, and their content has been analysed to show the recurrence of the themes of shared communal responsibility for children's moral guidance and the importance of providing it early in life.
