there some

leaps to a new
way of thinking
or behaving?
Change and Stability
 Are there some parts of who we are that remain stable

Our temperament? Our overall personality?
 Do some of our attributes change during development
(even while we maintain our sense of identity)?
Our abilities? Our interests? Our habits? Our traits?
Continuity vs. Stages
Are there certain
abilities and

Starting the Path to Personhood:
Prenatal Development
and the Newborn
Prenatal The Competent
Conception
Development Newborn
In the
beginning:
Sperm and egg unite to bring
genetic material together and
form one organism:
Conception
the zygote (the fertilized cell).
The Zygote Stage: First 10 to 14 Days
Prenatal  After the nuclei of the egg and
sperm fuse, the cell divides in 2, 4,
Development
8, 16, 100, 1000…
 Milestone of the zygote stage: cells
begin to differentiate into
specialized locations and structures

Implantation: The Embyro, 2 to 8 weeks
 This stage begins with the
multicellular cluster that implants in
the uterine wall.
 Milestone of the implantation stage:
differentiated cells develop into
organs and bones
Embryo
The Fetus

At nine weeks, hands and face
have developed; the embryo is
now called a fetus (“offspring”).
Placenta
At 4 months, many more
features develop.
Milestone of the fetal stage:
by six months, the fetus
might be able to survive
outside the womb
Fetal Life: The Dangers
Dangers
• Teratogens (“monster
makers”) are
substances such as
viruses and chemicals
that can damage the
developing embryo or
fetus.
• Fetal Alcohol
Syndrome (FAS) refers
to cognitive,
behavioral, and
body/brain structure
abnormalities caused
by exposure to alcohol
in the fetal stage.
