CHAPTER 11 Physical and Cognitive Development in Young Adulthood
Garrett, a 19
-
year
-
old, is a 2nd
-
year college student. He enjoys many privileges that could be
construed as “adult.” He drives a car, votes in elections, and owns a credit card. He shares an
apartment near his college campus with two other undergraduates. He drinks alcohol with his friends
at parties (albeit illegally) and has regular sexual relations with his girlfriend of 10 months. The
couple split up once and subsequently reunited. During
the separation, Garrett dated another young
woman. At this point, Garrett and his girlfriend have no plans to marry. He wanted to get a job
immediately after high school, but job opportunities in the trade he aspired to went to more
experienced workers. He
decided to give higher education a try. Garrett has little idea of what his
ultimate career path will be. Garrett’s father, who is divorced from Garrett’s mother, pays for his
tuition and housing costs. He has taken out loans to help finance his son’s edu
cation. Garrett’s
mother provides him with an allowance for food. He works part
-
time for low wages at a clothing store
in a local mall, which helps him pay for clothes and entertainment. Garrett is very responsible at
work, but he is an unenthusiastic coll
ege student. His study habits lean toward procrastinating and
then trying to make up for lost time by staying up all night to finish assignments by their deadlines.
When Garrett broke his wrist playing sports, his mother had to take a few days off from her
job to
accompany him to doctor’s visits. Her health insurance covered most of the bills. Yet, despite their
financial support, Garrett’s parents have no legal right to see Garrett’s college grades. Is Garrett an
adult? Scholars are likely to disagree abou
t the answer to this question. Most would agree that the
onset of adolescence is marked by the changes of puberty. But there are no easily observed
physical changes that signal entry into adulthood. Instead, adulthood is a social construction. One or
more
culturally determined criteria usually must be met before one’s maturity is established (Hogan
& Astone, 1986), and the criteria vary depending on the observer and the culture. In the past,
sociologists have emphasized the achievement and timing of marker
events as criteria for adulthood.
These have included completing formal education, entering the adult workforce, leaving the family
home, getting married, and becoming a parent. Around the middle of the last century, a large
proportion of the American popu
lation achieved these marker events between the ages of 18 and 24
(Rindfuss, 1991). However, if we evaluate our hypothetical student, Garrett, according to these
traditional marker events, he would not be an adult despite being in the right age range. From
a
sociological perspective, it seems to take longer to grow up today than it did at earlier points in
history for many reasons. Some of these include the demand for a highly educated workforce and
the increased cost of this education (Jacobs & Stoner
-
Eby,
1998), the difficulties inherent in earning
enough to support children and in achieving stable employment (Halperin, 1998b), and the
frequency of early, nonmarital sexual activity and the availability of contraception (Warner et al.,
1998). All have had p
rofound effects on the timing of life events. On one hand then, some markers of
adulthood are considerably delayed. For example, the median age for marriage in 1976 was about
22 or 23. By 2006, the median age for marriage had risen to about 27, a differenc
e of more than 4
years in only 30 years (Arnett, 2010). On the other hand, other indicators of adulthood, such as the
onset of sexual activity, occur much earlier than they did in the past. Such shifts in the timing of
marker events appear to have delayed
the onset of adulthood, especially in Western societies,
where these shifts have most often occurred. However, even in more traditional, nonindustrialized
cultures, the transition to adulthood can be a slow process. For example, after completing the
pubert
y rites that induct boys into the adult ranks of some societies, young males in about 25% of
cultures pass through a period of youth (Schlegel & Barry, 1991). In these societies, males are seen
as needing a period of time to prepare for marriage. Serving a
s warriors during the transition period,
for example, allows boys an opportunity to develop skills and to accumulate the material goods
needed to afford a family. Girls enjoy a similar period of youth in 20% of cultures. Thus, even in
many non
-
Western, tra
ditional societies, the movement to full adult status takes time. In cultures
such as that of the United States, the pathways to adulthood are remarkable in their variability, so
