What is developmental psychology?
The study of how people develop physically, cognitively, and socially across their life span.
What is a longitudinal study?
Research that follows subjects over time and retests them.
What is a cross-sectional study?
Research that compares subjects of varying ages at the same point in time.
How do researchers who emphasize experience and learning tend to characterize development?
As a gradually unfolding process.
How do researchers who emphasize biological maturation tend to characterize development?
As a series of genetically predisposed stages.
What is a stage theory?
A theory of how people develop socially, morally, psychologically, or cognitively in stages.
What is the end of history illusion?
The assumption that one won’t change very much in the future, even if they recognize how much they have changed in the past.
What is a zygote?
A fertilized egg from conception to two weeks after fertilization.
How long does it take a zygote to develop into an embryo?
2 weeks.
How does a zygote develop into an embryo?
Rapid cell division.
How many zygotes survive their first two weeks?
Less than half.
What is an embryo?
A developing human organism during the period between two weeks and eight weeks after conception.
What is a fetus?
The developing human organism from 9 weeks after conception until its birth.
What is a teratogen?
A chemical or viral agent that can harm an embryo or fetus during development.
What is fetal alcohol syndrome?
Physical and cognitive abnormalities caused by heavy drinking during pregnancy.
How do teratogens effect development?
They can leave epigenetic marks on the baby that turn genes on or off abnormally and cause developmental issues.
What is habituation?
A decreased response after prolonged exposure to something.
Chemicals that the placenta isn’t able to screen out that can harm an embryo or fetus are called
Teratogens.

Which stage theorist is known for a theory of cognitive development?
Jean Piaget.
Which stage theorist is known for a theory of psychosocial development?
Erik Erikson.
