Attempts to classify similarities and differences across cultures include even the long-discredited attempts in the nineteenth century to understand cultural evolution. which divided cultures into those at the stages or Savagery.

The earl iest scholarly paper Llsing statIstical techniljues to analyze culture traits in a sample of culture" also dates from the late nineteenth century (1~!lor. I XX9).

Anthropologists also benefited from the research theories and methods of psychology. Psychological anthropology depended heavily on personality theory developed by psychologists.

As these disciplines gained wider distribution throughout the world, non-Western .,. psychologists, in particular, studied the adolescents of their own cultures. This type of crosscultural research blends theories and methods, derived mainly from European and American sources, with a deep understanding of the local culture and condjtions. Research on Indian adolescent girls by Saraswathi and Dutta (1988) and Sharma (1996) provide good examples of the insights such an approach can reach. In spite of the success of Margaret Mead's CominR of Age in Samoa (1928), which was a study of Samoan adolescent girls, cultural anthropologists have until recently showed little interest in adolescence or adolescent development. They continued to refer to the rituals performed at around puberty in many societies as initiation into adulthood. This was so even after the work of Mead and, later, a few other anthropologists (e.g.. Elwin, 1947; Wilson. 1951) clearly showed that a socially marked stage of life between childhood and Cross-Cultural Studies of Adolescence 571 adulthood existed in the preindustrial and preliterate societies they examined. Exceptions to this genera] absence of anthropologica1 studies of adolescence are cross-cultural studies of initiation ceremonies by Cohen (]964) and Young (] 965). the latter a social psychologist. In both. the authors refer to a subsequent adolescent stage. but they do not discuss it. The lack of interest by anthropologists in adolescence may have been due in part to assumptions about adolescence. It was assumed by many that an adolescent stage is the social construct of modern societies. with schools that separate postpubertal individuals from adults for much of the time. According to this assumption, before widespread schooling appeared, teenage girls and boys were thought of as young adults, with adult-like responsibilities and interests. Anthropologists. who for the most part studied pre1iterate and preindustrial cultures, gave little attention to the developmental stage of indi viduals past puberty. Another reason for the neglect of adolescence may have come from psychology. Psychological anthropologists of the midtwentieth century, whose primary interest lay in the development of personality, were strongly influenced by Freudian and other branches of psychology that regard early influences as the determinants of adult personality and behavior. According to Freud. for example. significant socialization declines once young people have passed through the period of latency and reach the genital stage (Hall, 1954). Anthropologists, particularly psychological anthropologists, reported on the behavior of children, but they neglected adolescents. Thus, while there was plenty of evidence of adolescence in the ethnographic and historical literature-indeed, a later cross-cultural study of adolescence (Schlegel & Barry. ]991) would have been impossible without such evidence-it was usually buried in discussions of other topics or mentioned in passing. Coming (~f Age in Samoa (Mead, 1928) presented a challenge that most other anthropologists did not take up.

(Condon, 1987), an Australian community (Burbank, 1988), the ·"''',''-''I..IU. (Hollos & Leis, 1989), and in Morocco (Davis & Davis, 1989). A {je~:crilpti(m of the Harvard Adolescence cross-cultural studies examine a parvariable, a behavior or culture trait, in .several cultures or nations (the latter is cross-national), and usually offer tion for the similarities or differOne study of this type developed by Iogists js the controlled comparison. common form is a comparison of two cultures that are similar in most respects but differ in the behavior or trait of interest (i.e., the similarities are controlled fOr). An alternative is a comparison of (usually) two cLlltures that are different in most respects but are similar in the variable of interest controlling for the differences. In both instances, the point is to explain the difference or similarity. respectively. in the dependent variable. The study by HoJIos and Leis ( 1989) of adolescence in two Ibo villages. one more modern and one more traditional, is an example of the first form. Cross-cultural research has a more specific meaning than the general one, which applies to all research that compares cultures. In its specific sense, it refers to tests of hypotheses using ethnographic materials from a large representative sample of cultures. Data are coded from these materials according to a codebook. which consists of the variables to be coded (e.g.. present/absent or along a scale) and their operational definitions. The data are then analyzed using appropriate statistical techniques. and the findings are interpreted. For example. appendices I, II. and III of Schlegel and Barry (] 991) contain information on the sample. the codebook. and the statistical techniques used in their cross-cultural study of adolescent socialization. CENTRAL ISSUES IN THE CROSS-CULTURAL STUDY OF ADOLESCENCE Biological adolescence 1S universal. Recent research into the structure and processes of the developing brain make it clear that there are neurobiological changes as well (Steinberg et aI., 2006), and we can safeJy assume that these too are universal. The consensus is not so clear regarding adolescence as a stage of social development, however. Scholars conducting cross-cultural research on adolescence have asked several fundamental questions in this respect. Is social adolescence uni versal. or is it only found in a limited nUIllber of societies. modern ones with schooling and perhaps a few others'! When does social adolescence begin and when does it end'! What are the characteristics of social adolescence. 574 Cr()~~-Cultural JsSllt'~ in the Stud~ of Adolescent Development and hu\~ j" it "ill1ilar or Jifterent acrm" culture':.} \Vhich feature" of adolescc:nce differ bemeen girb and ho)". and which arc similar'!

The primary ...,OUITe or data for addrc:ssing these questions here is the research of the Adolescent Socialization Project. Unless othenl,'l"e noted the data ill thi" "cction are drawn frorn the re"ulting publication of the findings (Schlegd & Harry. 19Y I ). Thi~ book reponed 011 only <.! portion or the 34] variables in the project. coded separately for girls and boys.

(Details are found in the texl and appendices in Schlegel and Barry !199 J J.) These are all traditional cultures. and the ethnographic material Oil each refers to a specific community at a particular time. Is Adolescence as a Social Stage Universal? Here we have the "black swan" problem: One contrary case can negate the generalization, unless it can be accounted for by special circumstances. All of the cultures in the sample, with one possible exception with respect to girls, recognized a social stage between childhood and adulthood for both sexes, during which time the behavior and treatment ofyoung people differed from that oj both younger children and adults. In several cases there was an additional stage between adolescence and full adulthood. which we termed yowh, for one or hoth sexes. Such a stage. somewhat similar to what Arnell (2001) has called "elTlerging adulthood:' is a feature of most regions and social L'ias".c<; or Illodern societies. It also existed in some traditional ones slich a;-., ancient Athens and Sparta. Eurnpe since at lea"t the Middle Ages. and militaristic state" oj Africa like Zulu. Arnett (200 I) hu." conceptualized the youth stage of modern societies a" adulthood." with characteristic features that differentiate it quite markedly from the institutionalized youth stage" of preindustrial societies. Given the great variely of cultures in the sample by geographical placement. by subsistence techniques from hunting to advanced agriculture, and level of technological development. we can be fairly confident that social adolescellce is <.l constant aeross cultures for hoth sexes. [ts absence rather than its presence requires an explanation. cfhere may be at least two exceptions. one in the Standard Ethnographic Sample and one other, to the generalization that adolescence is a social universal. Girls of the Gros Ventre Indians of Montana and girls of some Australian aboriginal tribes (Burbank. 1(88) married and had sexual relations with their husbands before menarche. Aboriginal girls as young as 9 or lOin some cases. We do not have information on the lives of these girls, except that Gros Ventre co-wives. older than the new bride, treated her as a little sisler. It is impossible to say whether an adolescent stage was acknowledged for these very young wives or whether they were treated as adults and expected to behave like them. Nor do we know if the transition from childhood was marked by very early signs of puberty, which would mean that girls entered an adolescent stage before menarche. whether or not it ended at marriage. \Ve do know that in at least one Aboriginal tribe, the Aranda, social adolescence began with the appearance or thL' breast bud", an early sign of puberty. Many cultures have a special term for adole"cence as a period hctween childhood and adulthood. but most do not. We should not confuse the presence or absence of Jinguistic markers with social reality. however. The Navajo Indians of New Mexico and Ari/ona. whose language does ha\'e term". for udolescem girl and adolescent boy. did not have Central Issues in the Cross-Cultural Stud~ of Adolescence 575 distinctive markers in appearance or (Je-~I-'\.''-H· Ie behaviors to set off this stage. the other hand. their neighbors the Hopi. language does not have terms for adoheld public events where adolesgirls and boys could display themselves. . girls after menarche wore their hair in style that signaled that they were ready courtship. In another case, the Trobriand "Y;"n... nl"",." of Melanesia spoke of adolescents as flower of the village," without giving this a label. The Parameters of Adolescence The difficulty in determining age at the beginning and end of adolescence lies in the absence of good data on chronological age for most of the cultures in the Standard Ethnographic Sample. Age can only be estimated. A bet.ter measure, more in line with the way most peoples regard social age, is level of physical development. Although such features of physical development as tooth eruption (Bogin, 1999) and brain development (Steinberg et aI., 2006) seem to be universally consistent, reproductive maturation for both sexes is variable according to diet and possibly other conditions (Vizmanos & Marti-Hennenberg, 2001). For this reason, we defined social adolescence as beginning at around first menstruation and first ejaculation, unless otherwise indicated. We estimated menarche to be around age 14 in these relatively well-nourished popUlations, with spermarche 1 or 2 years later, unless there was information to the contrary, basing our estimates on Eveleth and Tanner (1976). There are several cases of girls' social adolescence beginning before menarche with earlier signs of pubel1al change. such as breast development. The Aranda, mentioned earlier, is one such case. Length ofAdolescence and Youth In most cultures social adulthood began at marriage. particularly for girls. In a few, full social adulthood was reached after one or more children were born to a couple. In other cases. a ceremony other than marriage marked the transition from boy to man. For the Hopi Indians of Arizona, a girl became a woman at marriage. but a boy became a man when he was initiated into one of the four male ceremonial societies. He did not marry until after this event. Length of social adolescence can vary between the sexes within a culture. In fact. boys' adolescence is frequently longer than girls' adolescence. Boys, whose growth spurt follows spermarche, do not reach their full physical development until some time after puberty, rarely before their late teens in the populations of the sample. Girls, whose growth spurt precedes menarche, develop adult-like bodies much earlier (although they go through a period of adolescent sub-fecundity before they are capable of maintaining a pregnancy) (Bogin, 1999). Thus, they are likely to be considered ready for adult life earlier than are their male peers, who have not yet attained an adult-like body. This, then, is a reason, grounded in biological development, for a longer adolescence for boys than for girls. A cultural reason for a longer male adolescence is that boys generally have to prove themselves capable of meeting the obligations of husband and father before the parents of a prospective bride will accept him as a son-inlaw. For both biological and social developmental reasons, the end result is that boys may still be considered adolescents or youth while the girls of their cohort are already married adu1ts and bearing children. A youth stage, when present typically begins and adolescence ends when the young person has attained full or almost fuII physical growth. This is rarely before the late teens. Indi viduals at that age are more developed, not only physically but also cognitively (Hooper, 2004), than boys and girls in their early teens. When full social adulthood is not reached until after the late teen-age years, usually sometime in the early to middle 205 or even later, cultures generally recognize a social stage that intervenes between adolescence and adulthood. 576 Cros,,-Cultural Is<,ucs in th(' Stud, of Adolescent De\ e10I.Hllent During this "wge. yuung pe()ple have more respull"ibilitie<.... and usually more freedom. than ad()le~cenh. withtlut the: <.:Inc! social recognitioll of adulthood.

CONSTANTS AND VARIANTS OF ADOLESCENCE ACROSS CULTURES This section examine" the constants and \ariants acro'>" cultures and hetv.. ecll the sc\es. Tile data are cultural rather than individual in 1 I Constants and Variants of Adolescence Across Cultures 577 : that is. each "subject" is a culture in sample. and the code for each variable of culture-present/absent or point on an ordinal scale-represents the best judgment the coders. For the purpose of rendering the data manageable. ordinal scales were converted into two categories, and these variables were analyzed statistically as above or below the mean. The following discussion highlights those findings from the Adolescent Socialization Project that, in this author's judgment, have the greatest relevance to issues in the study of contemporary adolescents. They are not necessarily presented in the form they were in the original cross-cultural report (Schlegel & Barry, 199]). Adolescents and Their Families The Household-the Primary Locus of Socialization In Western cultures, that is, European and European-derived cultures, a common family form for many centuries has been the nuclearfamily household, which consists of a married couple and their children, plus perhaps other unmarried or widowed adult kin, boarders, and household workers. Household authority rests with the central couple. The other common form has been the stem-family household. That contains an older couple and one of their children (more often a son, but a daughter if there is no male heir) plus that child's spouse and children. Household workers and unmarried kin may also belong to the household. This household form occurred in many world regions of peasant agriculture, including many parts of Asia, where the household required more than two working adults but limits on land or other household resources kept the household fairly small. In underpopulated African pastoral and farming regions, and in other places where vast tracts of arable land or grasslands constituted the landscape, the constraints were on shortage of labor rather than shortage of land. Extended-family household~ provided for household expansion by keeping some married children, most often sons. and their spouses and children in the parental home. These societies often promoted polygynous marriage. which expanded the domestic female labor force and provided more children for help in farming or herding. Wealthy families in traditional advanced societies like india and China also formed extended-family households to bring together the male kin. fathers. sons, and brothers that formed the family corporation and ran its enterprises. These are broad generalizations, for there are variations of these forms suited to local needs and the rules or customs of inheritance of property. Household structure and activities provided the social milieu within which children and adolescents were socialized and girls and boys learned their varying socia] roles. In the nuclear-family and extended-family households, before a demographic shift away from high fertility, the ratio of children to adults in the household was equal or high. For example. given four dependent children per woman, the nuclear-family household had a ratio of two children per one adult with whom they were likely to have reciprocal obligations and emotional ties. In the extended-family household. the ratio of children to adults might even be higher, particularly where there were polygynous marriages. The stem-family household. where polygyny was usually absent or uncommon, contained two parents and two grandparents, so the ratio was one-to-one. Since it often also contained unmarried adult children of the founding couple, uncles and aunts of the chi]dren, the ratio could be even lower. Thus, the social and emotional settings in which children were socialized were structured in different ways that depended on the household form. It is not surprising that where there were extended-family households, much rearing of young children was done by older siblings (Weisner. 1982) and cousins. and older children had authority over and responsibility for younger ones.

One universal or almost universal way is to provide entertainment for adults through displays of beauty and prowess in dancing and sports. These displays serve several purposes. Beyond providing entertainment, they allow adults to look the adolescents over and judge them as wOl1hy or unworthy of attention. In sl1l~1l communities where future social success and even marital prospects depend on hO\\1 they are viewed adult!'. young people are cageI' to he looked 011 favorably. And they all want to be admired by their fellow adolescents. particularly those of the opposite sex. In some cultures ill the sample and elsewhere. adolescent groups assumed responsibility for Constants and Variant!!. of Adolescence Across Cultures 58] certain rituals. community festivals. or other community projects. Groups of adolescent boys in some Japanese villages, and groups of adolescents ofboth sexes in some tribal regions of India, were responsible for keeping village paths clean. Ritual involvement by teenage girls and boys was common throughout Latin America. where the adolescent groups took on such duties as helping to clean the church or organize religious processions. Some tasks of community life. like taking charge of certain aspects of public festivals, were done by. groups of adolescent girls and boys, separately or together. This practice continues in Siena, Italy. today in the public dinners held as fundraisers by the city's district associations (contrade), where adolescents take part by helping set up, clean up, and serve food. Adolescent groups may also be given some responsibility for enforcing community rules of behavior. Reports of adolescent boys being allowed to engage in what otherwise would be considered antisocial acts-destroying property of rule violators, beating those who have aggressed against the community in some way, or publicly mocking those persons whose behavior threatens community moral standardscome from such disparate places as Pygmy villages in the Congo, American Chinatowns, and European peasant villages, respectively. In all these cases. groups of boys were permitted to aggress against disruptive adults with community approval. Participation as Individuals In traditional communities, adolescents were everywhere, working with adults or sharing responsibility. Adolescent girls and boys sold in the marketplace, participated with their family members in public rituals, and made themselves available to adults for tasks beyond the capabilities of younger children. Adolescents also participated as individuals in religious sodalities and civil organizations. Hopi girls and boys began to take part in sodality activities as children, taking on increasing responsibility as adolescents. In contemporary Germany. many adolescents from about age 15 or 16 join one or more of the clubs (Vereine). from hunting or singing to chess or stamp collecting. that are a prominent feature of German town and village life. The ethnographies used in the Adolescent Socialization Project. as well as others of cultures not in the sample. reveal that adolescents interacted freely and often with adults in the community. These adults were not just family members or adults who had authority over them in specific domains, like employers, religious leaders. or instructors. but also adults engaged in the same activities as the adolescents. Adolescents may have in many respects behaved differently, and were treated differently, than either children or adults, but they were not segregated. Sexual Attitudes and Practices Managing Adolescents' Sexual Behavior Families and communities everywhere must deal with adolescent children who are not considered ready for marriage, but who are highly motivated to engage in sexual relations. Adolescent girls are also capable of producing offspring. once they lose the protection of adolescent subfecundity. A matter of concern to a girl's family was the possibility of her pregnancy outside of marriage. Bastardy by itself was not a social problem where children of unwed mothers either stayed with the maternal grandparents when the mother married, or accompanied the mother into her new household. However, even where such children were not stigmatized in any way. they were still at a disadvantage. This is because there was usually no obligation for the biological father or his kin to provide whatever material or social benefits they normally provided to a man's children; if they did provide any, what they gave often depended on how they valued any particular child. This was true for matrilineal societies. where children belong to their mothers' kin group. as well as those with other forms of kinship. 5X2 Cros.s-Cultural Issues in th(, Study of Adolescent Development lVlanaging the "twng "exua] urge" of und 'youtll. lIllsllpeniscd hy ,HJUits during much (lltheir leisure time. concerned the COI1HIlU[1it).

The contrast of adolescents in the sample cultures with American adolescents is particularly striking. In the United States, extreme age segregation limits contacts across generations in civic or leisure-time activities. In many sectors of American society, adolescents are remarkably uninvolved with adults other than immed~ate family members and authority figures like teachers, coaches, youth leaders, and the like. Yet, it would be wrong to assume that adults other than parents play no meaningful roles in the lives of American adolescents. It would be easy to stereotype American teenagers as A Tribe Apart the title of a recent book (Hersch, 1998). As the work of Greenberger, Chen, and Beam, (1998) on VIPs (very important persons) shows, adolescents often have one or two adults other than parents to whom they turn for counsel. Hamilton and Darling (1998), among others, have also written about the importance of adult mentors in the lives of adolescents. Nevertheless, for many adolescents, the workplace and civil society provide few opportunities for adolescents to develop long-term close relationships with unrelated adults; and while young people may love grandparents and other kin, these are often not readily available. In the European nations where the author has done research, Italy and Germany, adolescents are much more involved with adults than American teenagers are, even though European adolescents attend school and spend considerable leisure time with peers. Kin and neighborhood networks in these countries provide more scope for adolescent-adult interaction. and institutions exist that promote such interaction. This is pronounced in Germany and other German-speaking countries and regions, which have extensive apprenticeship programs for adolescents. German ado1escents are also involved with adults in social clubs and civic organizations, the Vereine. Socialization for adulthood begins early when adolescents interact often and freely with adults. It eases the transition to adUlthood, as adolescents have many opportunities to observe aduJt behavior and select realistic role models from those they admire. Such interaction also sets the stage for possible friendships between the generations. These may be especially valuable as escape valves when pressures within the family and with peers mount. and adolescents can turn to adults, rather than other adolescents, for solace and advice. Institutions that involve adolescents with adults also provide settings for socialization that could be particularly important for the children of dysfunctional families. Work Most adolescents in traditional societies, where production generally took place in the home or the small job shop. were at work for much of their time. Schooling, where it existed, took up only part of the day. Among traditional elites, whose children did not do productive labor. the boys learned the skills they would need to be successful managers of family enterprises. soldiers, diplomats, or whatever elite men did, and girls learned the practical and social skills they would need as wives of these men. Such practical learning is found in apprenticeship programs in modern societies. While informal apprenticeships are widespread throughout the world, Germany, Austria, and Switzerland have established apprenticeship systems that employ the majority of their adolescent boys and girls aged 16 and older. These adolescents, who are either in blue-collar or white-collar apprenticeships, typically attend vocational school (with some academic subjects) for part of the time and work the rest of the time at their place of employment where they receive apprentice wages. These systems bring together employers, unions. and state educational bureaucracies in a relationship that is not always harmonious, but it does produce an institution that succeeds in preparing young people for future vocations. Apprenticeship programs modeled after the German system have been adapted to American high-school settings in a few places (SchlegeL 5X(, Cross-Cultural bsucs in thl' Study of Adulescent Dcvclopnwnt 1l)l)61.

Sexual Behavior Sexual activity among adolescents to the point ur "cxmd intercourse nov,' is more common. and III many quarters more tolerated. than it wa:-. fifty year:-. ago. The decline in the value on virginity corresponds in tillle with increa"ed opportunitie" of young people to be independent of family resources. and the correspondillg decline of adult authority over them. There ha:-. been a trickle-down effect from the sexual freedom of youth to the sexual freedom or adolescents. particularly as means of escapillg adult supervision have increased through access to cars and now the Internet. and adults thcmseh e:-. are more permissive toward sexual behavior olltside of marriage. Sexual permissiveness is not without consequences. The most obvious are the risks of pregnancy and contracting a sexually transmitted disease: another is the danger of sexual coercion by other adolescents. There are emol ional risk-.. as well. As we saw in the case of the Muria. sexual intimacy can intensify emotional attachment for (lne or both participants. and the almust inevitable break-up can be \cry di"turbing to adolescents unprepared to cope with "uch an emotional jolt Judging from the limited amount of available information. homoerotic behavior among adolescents is not uncommon in traditional cultures. nor i:-. it lIsually stigmatized. There is 110 c\idcncc that :-.uch ach in adolescence lead to a preference for homosexuality or even to an interest in it unle:-.s the individual already ha" that preference.

This wuuld only be true of the kind of homoerotic activities reponed for cultures or the sample: that j:-.. they occur among adolescent friends. v,:i1ere lhe dangers of sexual predatiun and the risk of sexually transmitted disease are minimal. not between adolescents and adults. Alltisocial Behal'ior The two most common form.'" oj misbehavior in the sample cultures are theft and fighting. Theft is associated with the difficulty or impossibility of obtaining desired objects. Juvenile theft in modern "ocieties is generally dealt with through attempts at prevention. and punishnlcnt. It i:-. probably impossible to curtail desire. as television and advertising keep desirable material objects constantly in view. and one mark of high status in the group is ownership or these objects. But a better way to prevent theft, by reducing the motive, would be to increase the means by which adolescents who otherwbe would not have acces~ to these objects could attain them in a legitimate manner. through earnings of some kind. Unlike adolescents in some nations. American teenagers who are not bound for college have little access to programs that vocationally train and gainfully employ them and prepare them for adult vocation", Violence was found where peer competition was high and cooperation 'iii as luw. Some competition for status. and for attractivenes:-. to the opposite sex. is prohably inherent in adolescent social relationships. However. young people are less likely to become angry and fight when they are working together on a project and depending on one another for success in completing it. Activities that place less emphasis on competition and more on cooperation. particularly cooperation with tangible results that bring recognition and reward to the whole cooperating group. would be a place to start. It would be very difficult to reduce adolescent misbehavior when adults frequently commit antisocial acts, for these variables are significantly correlated. Attempts to reduce youth delinquency alone are less likely to be effective than attempts that also address adult delinquency. Adolescent delinquency may be more than simply an epiphenomenon of adult delinquency; it may have causes of its own, but it exists within an environment of adult delinquency, as the cross-cultural study finds. DISCUSSION The cross-cultural method is correlational, not experimental, and it has the strengths and weaknesses of all correlational methods. Cross-cultural studies are most valuable when they are one of a set of studies that use different methods to address a topic (i.e., triangulation), but this can be said of any kind of study in the social sciences. The findings of crosscultural studies of adolescence, instructive by themselves, also point to directions that other studies can take using more restricted samples, such as a sample from a single culture. Some of the findings presented here have been il1ustrated with single-case studies, based on the field research of the author and others. Those that are relevant to research on modern adolescents received particular attention. Overall, cross-cultural data indicate that social adolescence is a panhuman phenomenon. The few ambiguous cases seem to be anomalies that could be explained by specific local conditions. Projecting into the past, it seems likely that our late-Pleistocene ancestors, and even earlier ones, recognized a social adolescence. This possibility is reinforced by studies of a developmental stage in the behavior of higher primates that is analogous to human social adolescence (Walters, 1987), We have also seen that social adolescence is generally coterminus with biological adolescence, but its beginning and ending can vary according to social conditions. Since biological Discussion 587 adolescence is broadly defined as the period during which the human reproductive system becomes active and matures. it is not surplising that social adolescence in most cases begins with some physical signs of puberty and ends with mamage, when the reproductive careers of most people become established. In cultures or social sectors where marriage is delayed for one or both sexes, a second pre-adult period intervenes between adolescence and full social adulthood. This we have termed youth. The presence of adolescence as a social stage has often been explained as a needed time for young people to learn adult skills and roles. This explanation is called into question when we learn that in many traditional societies, by pubel1y both sexes had acquired the survival skills they needed. Furthermore, it was common worldwide for adult married couples to live with the groom's or the bride's parents, permanently (until these parents died) or up to the time they were able to set up their own household. Presumably, a very young couple just past puberty would be as capable of survival as an older couple, for both would be embedded in the social networks that promote survival. So there is more to adolescence than just a time for extended learning of survival skills. As we have seen, this social stage has a biological basis. For girls, menarche. or other physical signs of puberty, signal the readiness to move out of childhood: for boys, secondary sex characteristics also indicate that the boy has reached sexual maturity and is no longer a child. For humans as for higher primates, eggs and sperm do not by themselves lead to full adult reproductive behavior (which in humans is generally preceded by the formation of some kind of pair bond). At the very minimum, female bodies have to develop sufficiently to caITY a pregnancy, and male bodies must be sufficiently large and developed to indicate that they can fulfill the requirements of manhood. Biological adolescence is the time when both sexes make this transi'ion. Social adolescence generally tracks biological adolescence. 5KK Cross-Cultural Issues in tht' Study of Adolescent De\ dopmellt with some \ ariations across culture" as to tht heginning and ending of this social stage.
