Child Development
Developmental psychology is the study of the physical, cognitive and psychological
growth of the individual throughout the life span. Ranges of expected normal
development are established and deviations and individual differences observed and
studied.
The influence of genetics and environment (nature and nurture) on child
development are examined to enhance our understanding and offer insight into
possible therapeutic interventions. Although the nature/nurture debate is often
heated, it is prudent to remember that most complex behavior is usually the result of
a combination of both genetic and environmental influences. The expression of
personality or intelligence is the result of many factors and is a mix of inherited
(genetic) and acquired (environmental) influences.
Developmental psychologists often describe stages of development. A stage is
usually defined by an expected age range and its accompanying identifiable
developmental milestones.
Below is a common classification of age ranges.

Biological Development
Prenatal development is characterized by rapid changes. It is broken down into
stages. We commonly hear of the three trimesters that mark the equal division of the
nine months of pregnancy. Prenatal development is also usefully divided into the
germinal, embryonic and fetal stages.
During the germinal stage, which begins at conception and lasts approximately
eight weeks; the zygote (the one celled organism formed by the unification of sperm
and ovum) cells divide rapidly. This growing mass of cells travels through the
mother's fallopian tube to the uterus. there, it becomes embedded into the uterine
lining and the placenta is formed. The placenta surrounds and protects the zygote
and brings in nutrients and oxygen while removing wastes.
At approximately two weeks after conception, the zygote has increased in mass and
become implanted in the uterus. At this point we begin to speak of it as the embryo.
The embryonic stage lasts from approximately week two to week eight. During this
period, the embryo continues to grow and most of the body systems and organs
begin formation.
The final stage of prenatal development, the fetal stage, lasts from approximately
week eight to birth. During the fetal stage growth continues by cell division and the
fetus becomes stronger, movement develops and the biological structures become
increasingly functional.
Cognitive Development
The growing ability to think, including memory, learning, language and perception is
called cognitive development. Children make great strides during their early years as
their first impressions interact with their inherited capacities to create concepts and
structures to facilitate growing understanding and mastery of their world.
One of the leading theorists of cognitive development was Jean Piaget. He
postulated four stages of cognitive development.

Psychological Development
Sigmund Freud was one of the most important of all the personality theorists. His
theory of child development postulated five "psychosexual stages" in which the
child's orientation to the world was based on the biological development of sexual
excitation which is focused on different body organs and systems (erogenous zones)
as the child develops. The child's activities during these stages are heavily
influenced by the gratification of sexual impulses.

1. Prenatal Stages of Development
Prenatal development is the process by which a baby develops inside the mother's
womb. Prenatal development takes about 38 weeks to complete. During this time, a
single cell becomes a full-term baby.
This time period is divided into different categories of development. The 3 primary
stages of prenatal development are the germinal period, the embryonic period, and
the fetal period. Each of these stages is important for reaching the ultimate goal of a
healthy baby.
Germinal Period
Pregnancy is considered to begin at first day of the mother's last menstrual
period. Conception typically occurs at what is considered the 2nd week of
pregnancy.
Conception is also the beginning of the germinal period of prenatal development.
This stage occurs during the first 2 weeks of development (or the 2nd - 4th weeks of
pregnancy).
The union of the sperm and egg cell forms a single cell called a zygote. The zygote
moves along the Fallopian tube toward the uterus. At the same time, the zygote is
rapidly dividing in a process called cleavage.
Once it reaches the uterus, the zygote becomes what is called a blastocyst, and it
begins to implant into the wall of the uterus. The germinal period ends when the
blastocyst is fully implanted into uterine tissue.
Embryonic Period
This is the embryonic period of prenatal development. This stage lasts from
implantation until about 8 weeks from the time of conception (or the 10th week of
pregnancy). This is the most important time of prenatal development because the
embryo is developing the foundations for a healthy baby.
The blastocyst that implanted in the uterus continues to divide rapidly after
implantation. Through a process called differentiation, cells begin to take on different
functions. One of the first examples of this is a division between the cells that will
make up the placenta and the cells that will make up the baby.
After this, a process called gastrulation forms three layers called germ layers. The
outer layer is called the ectoderm, the middle layer is called the mesoderm, and the
inner layer is called the endoderm.
Each germ layer will differentiate into different structures. The ectoderm will form
many outer tissues such as skin and hair, as well as most of the nervous system
tissues - including the brain. The mesoderm will form tissues inside the body such as
the lungs, bones, and muscles - including the heart. The endoderm will form tissues
such as the digestive tract and bladder, as well as other internal organs.
All of the essential structures have been formed (both inside and outside) by the time
the embryonic period comes to an end. The new title of fetus is now given to the
embryo.
Embryogenesis is a term that can be used to describe all of the processes of
embryo development up until the time it becomes a fetus.
Fetal Period
Fetal period. Starting with post conception week 9, or gestational week 11, the term
fetus is used. The fetus is characterized by fused eyelids and distinct human somatic
characteristics. The fetal period covers gestational weeks 11 to 26. During the fetal
period, the total body weight (TBW) increases from approximately 5 to 500 g. Fetal
period precedes embryonal period, during which a viable fetes is delivered.
At the beginning of the perinatal period, the eyelids separate and the eyes of the
fetus reopen.
Preschool ages (3 to 5 yrs)
Developmental milestones: ages 3 through 5
Knowing what to expect as your child grows can reassure you that your child is on
track with his peers or alert you to potential concerns. Below are some
developmental milestones to watch for during the preschool years.
Since birth, you’ve watched your child grow and develop. You’ve noted his height
and weight, when he crawled, stood, and walked, even when he spoke his first
words — and perhaps compared all of these developmental milestones of his
infant and toddler years to the “norms.” The preschool and early school years are
also full of changes. From three to five your child’s motor skills, language,
thinking, and social development change dramatically.

School Age Children (6 – 12 years)
Raising school age children can be awesome. Watching them try new activities,
cheering them on at athletic events and applauding their accomplishments at recitals
are usually some of the high points for most parents. However, achieving success is
often preceded with frustration and sometimes learning to accept one’s weaknesses
as will as celebrating and building on strengths. When will equipped parents can be
excellent coaches for their child no matter what the endeavor.
While toddlers and preschoolers need constant supervision, school age children
become gradually ready for more independence. However, learning to make good
choices and exercise self-discipline does not come easily for many. Parents need to
impart a moral code that the child gradually internalizes. As children struggle with
these important tasks parents must be able to provide praise and encouragement for
achievement but parents must also be able to allow them to sometimes experience
the natural consequences for their behavior or provide logical consequences to help
them learn from mistakes.
Pre vocational stage (13 to 18)
Vocational education is education that prepares people to work in a trade, in
a craft, as a technician, or in support roles in professions such
as engineering, accountancy, nursing, medicine, architecture, or law. Craft vocations
are usually based on manual or practical activities and are traditionally nonacademic but related to a specific trade oroccupation. Vocational education is
sometimes referred to as career education or technical education
Vocational education can take place at the secondary, post-secondary, further
education, and higher education level; and can interact with
the apprenticeship system. At the post-secondary level, vocational education is often
provided by a highly specialized institute of technology/polytechnic, or by
a university, or by a local community college.
Until recently, almost all vocational education took place in the classroom, or on the
job site, with students learning trade skills and trade theory from accredited
professors or established professionals. However, online vocational education has
grown in popularity, and made it easier than ever for students to learn various trade
skills and soft skills from established professionals in the industry.[2]
Vocational training is used to prepare for a certain trade or craft. Decades ago, it
used to refer solely to such fields are welding and automotive service, but today it
can range from hand trades to retail to tourism management. Vocational training is
education only in the type of trade a person wants to pursue, forgoing traditional
academics.
Vocational training, also known as Vocational Education and Training (VET) and
Career and Technical Education (CTE), provides job-specific technical training for
trades, such as auto repair, plumbing and retail. These programs generally focus on
providing students with hands-on instruction, and can lead to certification, a diploma
or certificate.
Vocational training can also give applicants an edge in job searches, since they
already have the certifiable knowledge they need to enter the field. A student can
receive vocational training either in high school, a community college or at trade
schools for adults.
In High School
Some vocational training is found in the form of high school CTE programs that
include academic study as well as a variety of courses and work experiences
designed to introduce students to trades ranging from construction, business and
health services to art and design, agriculture and information technology.
This form of education can be offered at high school campuses or separate
vocational training centers. The ultimate goal of these programs is to prepare
students for the job field and help them complete their high school education.
After High School
Community colleges and technical schools also offer a variety of vocational courses
and programs. This form of instruction includes hands-on training without the added
emphasis on standard subjects like math and English. Instead, students take specific
classes related to the job they're training for.
Vocational schools typically utilize cooperative training techniques, where students
are able to work in the job they're studying for and attend classes. Most vocational
training programs can be completed within six months to two years.
