- genetic plan determines how organs begin to form
- differentiation occurs which is when stem cells then begin to form into organs
teratogens

placenta
- forms as the zygotes outer cells attach to the uterine wall
- transfers nutrients and oxygen from mother to fetus
fetal alcohol syndrome
physical and cognitive abormalities in children caused by a pregnant woman heavy drinking
prenatal stages of development
zygote –> embryo –> fetus
during neonatal period…
babies are capable of responding to stimulation from all of their senses
during infancy period…
it’s a period of rapid development but is still heavily reliant on reflexive behavior
permanent reflexes
swallowing and blinking
moro reflex
the startle reflex
reflexes
a movement pattern triggered by a stimulus
neonatal reflexes
moro reflex
grasping reflex
rooting reflex
sucking reflex
critical period
optimal period when certain events must take place to facilitate proper development
rooting reflex
a touch near mouth will trigger the newborn to move their mouth and head towards the touch
imprinting
a powerful attraction occurs between infants and first moving object or individual they spend time with
contact comfort

insecure avoidant attachment
- do not orientate to attachment figure when investigating environment
- independent of figure physically and emotionally
