At the end of the chapter, you will be able to:
•discuss the relationship between physiological,
cognitive, spiritual, and social development to
understand your thoughts, feelings, and
behaviors;
•evaluate your own thoughts, feelings, and
behaviors; and
•show the connection between thoughts,
feelings, and behaviors in actual life situations.
•Psychology refers to the science of mental processes and
behaviors.
•To understand your whole personal development as an
adolescent, you first need to learn some essential concepts
such as physiological, cognitive, social and emotional, and
spiritual development.
•Since childhood, you have
experienced changesthat might
have brought you some
discomfort.
•The transition begins at puberty
or early adolescence where most
physical development changes
occur in both girls and boys.
Girls (12 to 14 years old)
•Breast develop as first pubertal
change
•Pubic hair appears next
•Hairs under the arms begins to grow
at 12 years old
•Menstruation may start as early as 10
years old and as late as 16 years old
•Hips become more defined and
curved
•Voice becomes firmer and fuller
Boys (12 to 14 years old)
It is difficult to know exactly when puberty is coming for boys because
changes occur gradually and over a period of time.
•Testicles enlargeas the first pubertal change
•Penis enlargesone year after the testicles
develop
•Appearance of pubic hair begins at 13.5 years
old
•Nocturnal emissions (or “wet dreams”) may
happen at 14 years old
•Hair under the arms and on the face grows
•Boys typically begin their
growth spurt up to two years
later than girls, giving them two
years of additional prepubertal
growth.
•However, height velocityis
faster in boys than in girls
during their growth spurt
reaching its peak of 9
centimeters at13.5 years old.
•Imagine a girl who starts her growth
spurt at age 11. She grows rapidly for
a couple of years and reaches near
her adult height by 14.
•A boy might not start his growth
spurt until age 13. But because he
had two more years of slower,
steady growth before puberty (ages
11 and 12), he ends up taller than the
girl by the time both finish growing.
Middle (15 to 17 years old) to Late
Adolescence (18 to 21 years old)
•By middle to late adolescence, the
physiological changes become more
stable.
•At this stage, you have become more
matureand profound with a sense of
acceptance and comfort, already
embracing these physical changes
despite some emotional turbulence at
certain points in your life.
•Refers to your capacity to think and reason.
•From your childhood years to your current stage,
your cognitive development reflects a more
complex process of thinkingcalled formal logical
operations, which include the following abilities:
a. Do abstract thinking and mental exercises
considering future possibilities
b.Form ideas and questionsfrom observed realities or
by simply imagining and realizing the connection of
one possibility to another
c. Consider and compare varied opinions
d. Figure out the process of thinking
During Middle Adolescence (14-17 years old)
•Has a more complex thinking process
•Uses the capacity to reason out, which makes
him/her sound philosophical and future-
oriented
•More comprehensivein delivering questions
and analysis
•Starts to consider his/her own “code of
ethics”(evaluating what is right and what is
wrong before acting out)
•Considers the question “who am I?”
•Is able to state more systematic life
goals
•Thinks about and begins tomake
his/her own plans
•Starts to plan out and consider long-
term possibilities
•Uses systematic thinking and begins
toinfluence relationshipswith others.
During Late Adolescence (18-21)
•More established thinkingfrom concrete to abstract
•Is now hypothetical with the capacity to discern using
basic principles applied to specific situations encountered
•Is more analytical and can figure out future possibilities
and outcomes of events
•Is able to manipulate and luster ideas and can create a
system of sorting these ideas or abstract thoughts to
come up with a more focused solution to specific concerns
•Is able to empathize and feel more for others with careful
considerationof varied points of view
•Is more sensitive to the needs of the others and more
interested in social issues
•Discovers and appreciates the diversity of people and
their perspectives, so that he/she could consider varied
options in solving problems
•Is more philosophical and idealistic
•Social and emotional development
during middle and late adolescence
areintertwined.
•As adolescents connect with others,
they bring with them emotions that
may affect the people they connect
with.
•Theymay experience some
difficulties in controlling their
emotionsand in being tactful when
communicating.
•During childhood years,the scope of
a person’s socialization is usually
limited to family and friends in the
neighborhood and school.
•In fact, children easily label others as
“friends”.
•During middle and late adolescence,
the range ofsocialization widens to
involve organizations where
adolescents get to meet a lot of
people.
•Thus, relationships become more
complex.
•At this stage, they can distinguish
“acquaintance” from “friendship”.
•Furthermore, more advanced cognitive
abilities results in a more enhanced
quality of interpersonal relationships.
•Since adolescents form different types of
relationships, some of these could
become more intimate like romantic
relationships which add color and
excitement to the life of adolescents.
•It is at this time also when they need to
balance time, energy, and attention.
•The advent and proliferation of
social media sitessuch as
Facebook, Twitter, and
Instagram and video
communication platforms such
asSkype, Zoom, and Google Meet
made socialization easier but less
personal.
•These post great challenges since
adolescents could miss out on
more meaningful relationships
outside social media.
•A research on adolescents’ spirituality
and involvement states that 50%of
young people engage in spiritual
activities every week and more than
75% share spiritual topics with their
peers.
•During adolescence, spiritual
awakening happens and adolescents
become aware of the existence of the
Divine,share their spiritual
experiences with peers, and find a
way to put faith into practice.
•Adolescents express their
spirituality byjoining clubs and
campus religious ministries
where they express themselves
and find meaning for certain
aspects of their adolescent life.
