− | A '''child''' (plural: '''children''') is a young [[human]]. Depending on context it may mean someone who is not yet an [[adult]], or someone who has not yet reached [[puberty]] (someone who is '''prepubescent''').
| |
| | | |
− | '''Child''' is also the opposite of [[parent]]: adults are the children of their parents despite their maturation beyond infancy; for example ''"Benjamin, aged 26, is the child of Tobias, aged 63"''. Similarly in a generalized sense, see [[child node]].

| |
− | ==Gender==
| |
− |
| |
− | A female child is called a ''[[girl]]'' and a male child is a ''[[boy]]'' (though a small percentage of humans are [[intersexual]], this is a distinction of biological sex, not necessarily social or psychological [[gender identity|gender]]). Apart from the [[reproductive system]], young children do not differ much by sex. Whether cultural and parental practices emphasize or weaken [[gender identity]] is subject to debate. In general, the extent to which gender identity is formed during childhood or congenital is a matter of much debate within [[psychology]] and [[genetics]]. See also [[nature versus nurture|nature vs. nurture]].

− | ==Law==
| |
− |
| |
− | In [[law]], a person who is not yet a legal adult is known as a [[minor (law)|minor]] (known in some places as a ''juvenile'', or, in others, as an ''infant''). For example, in many countries a person under the age of 18 is a minor. Most countries give additional legal protection to minors despite--and oftentimes due to--their underage status, and all [[United Nations]] member states except the [[United States]] and [[Somalia]] have ratified the UN [[Convention on the Rights of the Child]], although not all of them have followed it.

− | ==Development==
| |
− |
| |
− | ''Child development'' is the study or examination of processes and mechanisms that operate during the physical and mental development of an infant into an adult.
| |
− |
| |
− | ''Pediatrics'' is the branch of [[medicine]] relating to the care of children. It encompasses ages from prenatal to teenagers and even young adults (ages 0-21 years).
| |
− |
| |
− | Terms for stages of age-related physical development include, with their approximate age ranges:
| |
− |
| |
− | *[[zygote]], the point of [[conception]], fertilization
| |
− | *[[embryo]]; in the later stages also called [[fetus]]
| |
− | *[[childbirth]]
| |
− | *''Child''
| |
− | **[[infant]] (baby, newborn) (0-1.5)
| |
− | **[[toddler]] (1.5-4)
| |
− | **[[primary school]] age (also called '''prepubescence''') (4-12)
| |
− | ***[[elementary school]] age (also called '''middle childhood''') (4-8)
| |
− | ***[[preadolescence]] (preteen, or '''late childhood'''. The child in this and the previous phase are called ''schoolchild'' (''schoolboy'' or ''schoolgirl''), when still of primary school age.) (9-12)
| |
− | *[[adolescence|adolescence and puberty]] (teenage) (13-19)
| |
− | *[[young adult]] (16-25)
| |
− | *[[adult]] (16-21 or older; exact minimum age may vary)
| |
− | **[[early adulthood]] (20-39)
| |
− | **[[middle age]] (40-59)
| |
− | **[[advanced adult]]/[[Senior citizen]] (60+)
| |
− | *[[death]] (occurs at various ages depending on person)
| |
− |
| |
− | Also sometimes used are terms that specify one's age in decades, such as:
| |
− |
| |
− | *[[twenty something]] (20-29)
| |
− | *[[thirty something]] (30-39)
| |
− | *[[quadragenarian]] (40-49) (rarely used since 1980)
| |
− | *[[quinquagenarian]] (50-59)
| |
− | *[[sexagenarian]] (60-69)
| |
− | *[[septuagenarian]] (70-79)
| |
− | *[[octogenarian]] (80-89)
| |
− | *[[nonagenarian]] (90-99)
| |
− | *[[centenarian]] (100-109)
| |
− | *[[supercentenarian]] (110+)

| |
− | Note: the [[Tanner stages]] can be used to approximately judge a child's age based on physical development.

| |
− | * [[music lessons]]

− | ==Human development ==
| |
− |
| |
− | '''Human development''' refers to all forms of development above, often in the context of [[clinical psychology|clinical]] or [[developmental psychology]], or as [[human development theory]] (in [[economics]], an outgrowth of [[welfare economics]]).
| |
− |
| |
− | Both the psychological and economic fields share a special concern with [[education]] and [[language]] fluency including [[literacy]] and [[numeracy]], and with identification and development of more unique talents into the [[capital (economics)|economic variable]] known as [[individual capital]].
| |
− |
| |
− | Earlier branches of economics see humans in terms of labour for [[production]], [[means of persuasion]] or [[means of protection|protection]], which tend to be skills acquired only in adolescence and adulthood. The human development view is more evident in [[sports]], [[music]] and other [[performing arts]], such as [[child actor|acting]] where the '''child''' begins [[training]] often as early as three years of age. Think of [[Tiger Woods]] and his early practice [[golf]]ing.
| |
− |
| |
− | While there are problems with such early "streaming", [[child murder]], [[child abandonment]], [[military use of children]] and other major social ills are thought to be reduced by a human development approach – as there is a [[value of life|high value assigned to children]] by the state.
| |
− |
| |
− | The [[UN Human Development Index]] is a means of [[measuring well-being]] used to rank states by these criteria. Although [[child abuse]] is thought to be lower in countries with a high ranking on this Index, that is not easily proven.
