Document Summary

Critical &sensitive periods: critical period: age experiences must occur for development to proceed normally, sensitive period: optimal age range for certain experiences. Cross-sectional design: compare people of different ages at the same point in time. Longitudinal design: repeatedly tests same cohort as it grows older. Sequential design: combines cross-sectional & longitudinal approaches. Germinal stage: first 2 weeks of development, 1 sperm fertilizes female egg: zygote: fertilized egg. Embryonic stage: end of 2nd week-8th week after conception, cell mass now is called embryo: placenta: membranes allow nutrients to pass from mother"s blood to umbilical cord. Umbilical cord: blood vessels that carry nutrients & oxygen to embryo, waste products back from embryo to mother. 9th week embryo: fetus: fetal stage: until birth, muscles become stronger & bodily systems continue to develop. At 24 weeks eyes open, 28 weeks fetus attains age of viability.
