Chapter 10 Review Flashcards
Conception to 2 weeks
Germinal stage
Zygote becomes a mass of cells that implants in the uterine wall and the placenta begins to form
Germinal stage
2 weeks to 8 weeks
Embryonic stage
Most vital organs and bodily systems begin to form (very vulnerable)
Embryonic stage
8 weeks to birth
Fetal stage
Organs continue to grow and gradually begin to function
Fetal stage
22 to 26 weeks
Age of viability
Inside uterus; protects baby against injury
Amniotic sac
Drinking fluid; keeps temp at constant 100 degrees Fahrenheit
Amniotic fluid
Connected to baby via umbilical chord; provides oxygen and nourishment
Placenta
Prime age span for childbirth
20 to 28
Higher chance for this type of problem in older men’s children
Gene problems
Most important from last 3 months of pregnancy to 2 years
Nutrition
Causes babies to be born with some degree of mental retardation and distorted face and body features
Alcohol (FAS)
Causes lighter weight babies with respiratory problems
Nicotine
Causes babies to often be born addicted
Street drugs
Causes possibility of hemorrhage during birth - dangerous for children and mother
Aspirin
Vision capacities of newborns
Near-sighted - can see less than 8 inches in front of their face

Hearing capacities of newborns
Very well-developed
Effects of high / low pitch sounds
High - keep awake
Low - put to sleep
Taste capacities of newborns
More developed at birth than at any other time in life
Smell capacities of newborns
Very acute - can tell difference between mother’s breast milk and other types
Increases newborns’ risk for birth complications and deficits
Maternal malnutrition
Can interfere with prenatal development
Maternal illness
STD’s that can be passed to newborns
Genital herpes and AIDS
Nature
Heredity
Nurture
Environment
Nature determines potential, nurture determines expression
Interactionist position
Heat to foot trend
Cephalocaudal trend
Center - outwards trend
Proximodistal trend
Follows cephalocaudal and proximodistal trends
Motor development
Attributes to early progress in motor skills
Maturation
Research suggests this is also important to early motor skill progression
Infant’s exploration
Cross-cultural research shows both these traits are influential in developing motor skills
Maturation and environment
1 group of subjects is observed repeatedly over time
Longitudinal research
Group of subjects of varied ages are observed at a single point in time
Cross-sectional research
Refers to close emotional bonds of affection that develop between infants and caregivers
Attachment
