Nature/Nurture
How do genetic inheritance
(our nature) and
experience (the nurture we
receive) influence our
behavior?
Stability/Change
Do our early personality
traits persist through life, or
do we become different
persons as we age.
Continuity/Stages
Is developmental a gradual,
continuous process or a
sequence of separate
stages?
developmental psychology =
Study of humans from
womb to tomb.
zygote
a fertilized cell with cells that
become increasingly diverse
At about 14 days the zygote turns into an
embryo
embryo 6 weeks
6 WEEKS
Notice the large neural tube and the formation of
the heart and other internal organs.

conception 2 weeks
At about 14 days the zygote
turns into an
embryo (a and b).
embryo 6 weeks
Notice the large neural tube and the formation of
the heart and other internal organs.
embryo 7 weeks
Eyes, fingers, toes
and most internal
organs have formed,
but are not yet fully
functional
fetus: 8-9 weeks
The tiny baby is
protected by the
amniotic sac, filled with
fluid. The arms and legs have lengthened, and fingers can be seen.
The toes will develop in
the next few days.
at 9 weeks
an embryo turns into a fetus
10 weeks
heart and baby teeth form (looks like new
An opening the atrium of the heart and the presence of a bypass valve divert much of the
blood away from the lungs, as the child’s blood is oxygenated
through the placenta
12 weeks
notice the webbing
on the fingers, with
the digits still fused
14 weeks
Muscles lengthen and
become organized. mother feels kicking
15 weeks
mother eats and it affects movement of baby
baby gains taste buds
