areas of life, by means of friendships,
sports, and learning.
Defined as being the ages between 11
and 19 years old. There are drastic
changes that take place in this stage of
development. Not only is the
physiological part of the adolescent
changing but so is the psychological as
well. Moving from child into an adult is
a dramatic change. The intermediary
period reaches physical maturity by
developing sexual characteristics.
Women begin to develop breast buds
around 8 and fully develop during late
adolescence. Between the ages of 9-
10 pubic hair growth and hair in the
armpits and legs occur. In males there
are changes in the scrotal and testicular
areas at around the age of 9 along with
enlargement of the penis as it achieves
its fully developed range around 15 or
16. Pubic hair grows and hair on the
face and armpits as well. Change in the
voice also occurs at this time.
This is the stage of development where
the adolescent is able to ponder
analytically about all reasonable
interactions contained by a problem.
They shift from tangible thinking to
conventional rational processes. They
develop their own view of the world. If
emotional problems come up they may
have more difficult time thinking in a
complicated way. The more difficult
thoughts are focused on individual
choices in education and home,
including schoolwork as well as
questioning authority as well as the
ability to verbalize and shape their own
opinion and observations on a variety of
topic such as which sports are better to
play or what group would be better to
be included in or what personal
appearances are desired or appealing
or what rules their parents make should
be changed. Question more to a greater
extent, scrutinize more expansively,
forms own identity. Begins to reflect
long term.
This is the stage of self-consciousness,
sensitivity enveloping surroundings and
amplified anxiety over their view of their own
body, along with agonizing assessment
relating self and companions. Adolescents
spend a substantial quantity of time on
thinking about themselves so they believe
that other people are thinking about them
too. At this stage of development they begin
to shape their identity. Friendships are
more unpredictable and girls tend to be
jealous of other girls. They learn to develop
relationships based on faithfulness and
closeness. They frequently feel that others
are watching them. Adolescents tend to
think they are the only ones to have ever
experienced what they are feeling. They are
inclined to exhibit the "Personal Fable"
syndrome. This is a belief that makes them
think nothing bad will happen to them.
Early Adulthood The first signs of aging begin such
as fine lines and wrinkles.
Metabolism may begin to slow
down slightly which may result in
‘filling out’ for some. The body
reaches its physical peak of strength,
health and fertility for both sexes.
Prior knowledge is now being used
and applied to reach achievements.
Intelligence is used to maintain
proper working relationships such as
those at work or in romance. An
increased ability to have multiple
focuses and concerns due to having
almost full responsibility for oneself
for the first time.
The need for intimacy as well as
isolation grows. Early adults begin to
realize their own independence as
members of society and begin to realize
the need for love and compassion in
order for society and their own lives to
run smoothly.
The urge to ‘settle down’ begins to come
into play. Young adults begin to plan for
the rest of their independent adult lives
