Adolescence (lat "adolescere" = (to) grow) is a transitional stage of physical and mental human development that occurs between
childhoodand adulthood. This transition involves biological (i.e. pubertal), social, and psychological changes, though the biological or physiological ones are the easiest to measure objectively. Historically, pubertyhas been heavily associated with teenagers and the onset of adolescent development.www.youthspecialties.com] cite web| title=Questions about Sex, Puberty, and Periods, for adolescents and their parents: 12.

The end of adolescence and the beginning of adulthood varies by country as well as by function, as even within a single country there will be different ages at which an individual is considered mature enough to be entrusted with particular tasks, such as driving a vehicle, having sexual relations, serving in the armed forces, voting, or marrying.
Puberty is the stage of the
lifespanin which a childdevelops secondary sex characteristics (for example a deeper voice or larger adam's applein boys, and development of breastsand more curved and prominent hips in girls) as his or her hormonal balance shifts strongly towards an adult state. This is triggered by the pituitary gland, which secretes a surge of hormones, such as testosterone(boys) or estrogenand progesterone(girls) into the bloodstream and begins the rapid maturation of the gonads: the girl's ovariesand the boy's testicles. Some boys may develop Gynecomastiadue to an imbalance of sex hormones, tissue responsiveness or obesity. Put simply, puberty is the time when a child's body starts changing into an adult's body.
The onset of puberty in girls appears to be related to body fat percentage. In most Western countries, the average age of a girl's first menstrual period, or
menarche, fell in a decreasing secular trend.Fact|date=September 2007 Girls start going through puberty earlier than boys, although there have been cases of boys having signs of puberty as early as the age of 9. The average age for girls to start puberty is 10-12 while the average age for boys to start puberty is 12-14.
Adolescent psychology is associated with notable changes in mood sometimes known as
mood swings. Cognitive, emotionaland attitudinal changes which are characteristic of adolescence, often take place during this period, and this can be a cause of conflicton one hand and positive development on the other.
Because the adolescents are experiencing various strong cognitive and physical changes, for the first time in their lives they may start to view their friends, their
peer group, as more important and influential than their parents/guardians. Because of peer pressure, they may sometimes indulge in activities not deemed socially acceptable, although this may be more of a social phenomenon than a psychological one. [cite web|url=http://www.oberlin.edu/faculty/ndarling/adpeer1.htm|title=www.oberlin.edu/faculty/ndarling/adpeer1.htm |accessdate=2007-07-27] This overlap is addressed within the study of psychosociology.
The home is an important aspect of adolescent psychology: home environment and family have a substantial impact on the developing minds of teenagers, and these developments may reach a climax during adolescence. For example, abusive parents may lead a child to "poke fun" at other classmates when he/she is seven years old or so, but during adolescence, it may become progressively worse, for example, the child may now be using drugs or becoming intolerably violent among other classmates. If the concepts and theory behind of right or wrong were not established early on in a child's life, the lack of this knowledge may impair a teenager's ability to make beneficial decisions as well as allowing his/her impulses to control his/her decisions.
In the search for a unique social identity for themselves, adolescents are frequently confused about what is 'right' and what is 'wrong.'
G. Stanley Halldenoted this period as one of "Storm and Stress" and, according to him, conflictat this developmental stage is normal and not unusual. Margaret Mead, on the other hand, attributed the behavior of adolescents to their culture and upbringing. [cite web|url=http://www.mnsu.edu/emuseum/cultural/anthropology/Mead.html|title=www.mnsu.edu/emuseum/cultural/anthropology/Mead.html |accessdate=2007-07-27] However, Piaget, attributed this stage in development with greatly increased cognitive abilities; at this stage of life the individual's thoughts start taking more of an abstract form and the egocentric thoughts decrease, hence the individual is able to think and reason in a wider perspective. [cite web|url=http://www.etr.org/recapp/theories/AdolescentDevelopment/developmentalTheories.htm|title=www.etr.org/recapp/theories/AdolescentDevelopment/developmentalTheories.htm |accessdate=2007-07-27] Positive psychologyis sometimes brought up when addressing adolescent psychology as well. This approach towards adolescents refers to providing them with motivation to become socially acceptable and notable individuals, since many adolescents find themselves bored, indecisive and/or unmotivated. [Thomas Kelly, [http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&list_uids=15563037&dopt=Abstract Positive psychology and adolescent mental health: false promise or true breakthrough?] , 2004]
Adolescents may be subject to peer pressure within their adolescent time span, consisting of the need to have sex, consume alcoholic beverages, use drugs, defy their parental figures, or commit any activity in which the person who is subjected to may not deem appropriate, among other things. Peer pressure is a common experience between adolescents and may result briefly or on a larger scale.
It should also be noted that adolescence is the stage of a psychological breakthrough in a person's life when the
cognitive developmentis rapid [cite web|url=http://www.newcastle.edu.au/group/ajedp/Archive/Volume_7/v7-wan.pdf|title=www.newcastle.edu.au/group/ajedp/Archive/Volume_7/v7-wan.pdf |format=PDF|accessdate=2007-07-27] and the thoughts, ideas and concepts developed at this period of life greatly influence the individual's future life, playing a major role in character and personality formation. [cite web|url=http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&list_uids=14484851&dopt=Abstract|title=www.ncbi.ncmd=Retrieve&db=PubMed&list_uids=14484851&dopt=Abstract |accessdate=2007-07-27]
Struggles with adolescent identity and depression usually set in when an adolescent experiences a loss. The most important loss in their lives is the changing relationship between the adolescent and their parents. Adolescents may also experience strife in their relationships with friends. This may be because of things their friends do, such as smoking, that they feel if they don't do, they'll lose their friendship. Teen depression can be extremely intense at times because of physical and hormonal changes but emotional instability is part of being a teenager. Their changing mind, body and relationships often present themselves as stressful and that change, they assume, is something to be feared. [ [http://www.cure-your-depression.com/adolescent-identity-and-depression.html Adolescent Identity and Depression: Why and What To Do ] ]
Views of family relationships during adolescence are changing. The old view of family relationships during adolescence put an emphasis on conflict and disengagement and thought storm and stress was normal and even inevitable. However, the new view puts emphasis on transformation or relationships and maintenance of connectedness.
Adolescent sexuality refers to sexual feelings, behavior and development in
adolescentsand is a stage of human sexuality. Sexuality and sexual desire usually begins to appear along with the onset of puberty. The expression of sexual desire among adolescents (or anyone, for that matter), might be influenced by family values and the culture and religion they have grown up in (or as a backlash to such), social engineering, social control, taboos, and other kinds of social mores.The risks of adolescent sexual activity is sometimes associated with: emotional distress (fear of abuse or exploitation), sexually transmitted diseases (including HIV/ AIDS) and pregnancy through failure or non-use of contraceptives. In terms of sexual identity, all sexual orientations found in adults are also represented among adolescents.
According to anthropologist
Margaret Meadand psychologist Albert Bandura, the turmoil found in adolescence in Western society has a cultural rather than a physical cause; they reported that societies where young women engaged in free sexual activity had no such adolescent turmoil.
In a 2008 study conducted by
YouGovfor Channel 420% of 14−17-year-olds surveyed revealed that they had their first sexual experience at 13 or under.Cite web|url=http://sexperienceuk.channel4.com/teen-sex-survey|title=Teen Sex Survey|accessdate=2008-09-11|publisher=Channel 4|year=2008]
age of consentto sexual activity varies widely between international jurisdictions, ranging from 12 to 21 years, although some governments, such as Canada's, are planning to raise the age to at least 16 in an effort to reduce the incidence of the most serious STD's, pregnancy among teenage girls, and the sexual abuse and exploitation of younger teens.
In commerce, this generation is seen as an important target.
Mobile phones, contemporary popular music, movies, televisionprograms, web sites, sports, video gamesand clothes are heavily marketed and often popular amongst adolescents.
In the past (and still in some cultures) there were ceremonies that celebrated adulthood, typically occurring during adolescence. "
Seijin shiki" (literally "adult ceremony") is a Japanese example of this. Upanayanamis a coming of age ceremony for males in the Hindu world. In Judaism, 12-year-old girls and 13-year-old boys become Bat or Bar Mitzvah, respectively, and often have a celebration to mark this coming of age. Among some denominations of Christianity, the riteor sacramentof Confirmation is received by adolescents and may be considered the time at which adolescents become members of the church in their own right. (There is also a Confirmation ceremony in some Reform Jewish temples, although the bar or bat mitzvah ceremony appears to have precedence.) African boys also have a coming of age ceremony in which, upon reaching adolescence, the males state a promise to never do anything to shame their families or their village. This was also continued among African-Americanslaves in the early days of slavery before the practice was outlawed. In United States, girls will often have a "sweet sixteen" party to celebrate turning the aforementioned age, a tradition similar to the quinceañerain Latinculture. In modern America, events such as getting your first driver's license, high school and later on college graduation and first career related job are thought of as being more significant markers in transition to adulthood.
Adolescents have also been an important factor in many movements for positive social change around the world. The popular history of adolescents participating in these movements may perhaps start with Joan of Arc, and extend to present times with popular
youth activism, student activism, and other efforts to make the youth voiceheard.
Legal issues, rights and privileges
Internationally, those over a certain age (often 18, though this varies) are legally considered to have reached the
age of majorityand are regarded as adultsand are held to be responsible for their actions. People below this age are considered minors and are children. A person below the age of majority may gain adult rights through legal emancipation.
Those who are under the age of consent, or legal responsibility, may be considered too young to be held accountable for criminal action. This is called "doli incapax" or the
defense of infancy. The age of criminal responsibility varies from 7 in Indiato 18 in Belgium. After reaching the initial age, there may be levels of responsibility dictated by age and type of offense, and crimes committed by minors may be tried in a juvenile court.
legal working agein Western countries is usually 14 to 16, depending on the number of hours and type of employment. In the United Kingdomand Canada, for example, young people between 14 and 16 can work at certain types of light work with some restrictions to allow for schooling; while kids over 16 can work full-time (excluding night work). Many countries also specify a minimum school leaving age, ranging from 10 to 18, at which a person is legally allowed to leave compulsory education.
age of consentto sexual activity varies widely between jurisdictions, ranging from 12 to 21 years, although 14 to 16 years is more usual. In a 2008 study of 14−17-year-olds conducted by YouGovfor Channel 4it was revealed that one in three 15-year-olds were sexually active.Cite web|url=http://sexperienceuk.channel4.com/teen-sex-survey|title=Teen Sex Survey|accessdate=2008-09-11|publisher=Channel 4|year=2008]
Sexual intercourse with a person below the local age of consent is treated as the crime of
statutory rape. Some jurisdictions allow an exemption where both partners are close in age; for example, a 16-year-old and an 18-year-old. The age at which people are allowed to marry also varies, from 9 in Yemento 22 for males and 20 for females in China. In Western countries, people are typically allowed to marry at 18, although they are sometimes allowed to marry at a younger age with parental or court consent. In developing countries, the legal marriageable age does not always correspond with the age at which people actually marry; for example, the legal age for marriage in Ethiopiais 18 for both males and females, but in rural areas most girls are married by age 16.
In most democratic countries, a citizen is eligible to vote at 18. For example, in the
United States, the Twenty-sixth amendment decreased the voting age from 21 to 18. In a minority of countries, the voting age is 17 (for example, Indonesia) or 16 (for example, Brazil). By contrast, some countries have a minimum voting age of 21 (for example, Singapore) whereas the minimum age in Uzbekistanis 25. Age of candidacyis the minimum age at which a person can legally qualify to hold certain elected government offices. In most countries, a person must be 18 or over to stand for elected office, but some countries such as the United States and Italyhave further restrictions depending on the type of office.
The sale of selected items such as
cigarettes, alcohol, and videos with violent or pornographic content is also restricted by age in most countries. In the U.S, the minimum age to buy an R-rated movie, M-rated game or an album with a parental advisory label is 17 (in some states 18). In practice, it is common that young people engage in underage smoking or drinking, and in some cultures this is tolerated to a certain degree. In the United States, teenagers are allowed to drive between 14-18 (each state sets its own minimum driving age of which a curfewmay be imposed), in the US, adolescents 17 years of age can serve in the military. In Europeit is more common for the driving age to be higher (usually 18) while the drinking age is lower than that of the US (usually 16 or 18). In Canada, the drinking age is 18 in some areas and 19 in other areas. In Australia, universally the minimum drinking age is 18, unless a person is in a private residence or is under parental supervision in a licensed premises. The driving age varies from state to state but the more common system is a graduated system of "L plates" (a learning license that requires supervision from a licensed driver) from age 16, red "P plates" (probationary license) at 17, green "P plates" at 18 and finally a full license, i.e. for most people around the age of 20.
The legal gambling age also depends on the jurisdiction, although it is typically 18.
The minimum age for donating blood in the U.S is 17 although it may be 16 with parental permission in some states such as New York and Pennsylvania.
A number of social scientists, including anthropologist
Margaret Meadand sociologist Mike Males, have noted the contradictory treatment of laws affecting adolescents in the United States. As Males has noted, the US Supreme Court has, "explicitly ruled that policy-makers may impose adult responsibilities and punishments on individual youths as if they were adults at the same time laws and policies abrogate adolescents’ rights en masse as if they were children."
The issue of
youth activismaffecting political, social, educational, and moral circumstances is of growing significance around the world. Youth-led organizations around the world have fought for social justice, the youth voteseeking to gain teenagers the right to vote, to secure more youth rights, and demanding better schools through student activism.
Since the advent of the
Convention on the Rights of the Childin 1989 (children defined as under 18), almost every country (except the U.S. & Somalia) in the world has become voluntarily legally committed to advancing an anti-discriminatory stance towards young people of all ages. This is a legally binding document which secures youth participationthroughout society while acting against unchecked child labor, child soldiers, child prostitution, and pornography.
