Unit 7 : Development Modules 45-48 Flashcards
Embryo
Developing human organism from 2 weeks after fertilization until second month
- form takes shape, heartbeat develops
- inner cells - embryo
- outer cells - placenta
Fetal alcohol syndrome (FAS)
Physical and cognitive abnormalities in children caused by pregnant woman heavy drinking. Causes small out of proportion heads and abnormal facial features
Fetus
Developing human organism from 2 months to birth
- 25 - 27 week baby more chance of survival

sequential, biological growth process uninfluenced by experience.
Biological growth processes that enable orderly changes in behavior, relatively uninfluenced by experience (sets basic course of dev.)
- sit up → stand up → walk → run
- thinking → memory → language
- frontal lobe develops last
Nature nurture debate
How genetic inheritance (nature) interacts with our experiences (nurture) to influence development
Rooting reflex

Teratogens
harmful chemicals and viruses for the child - alcohol - smoking - drugs (meds + bad) - radiation - fish -caffeine “Monster maker” agents; chemicals and viruses that can reach the embryo/fetus during prenatal development and cause harm
zygote
fertilized egg
- rapid cell division
- becomes embryo when zygote attaches to uterus wall

schema
concept/framework to organize info

birth to 2 yo
explore through senses and actions (look, hear, touch, mouth)
object permanence
awareness that things continue to exist even when not seen
- out of sight out of mind
preoperational stage
2- ~6/7 yo
