Document Summary

Developmental psychology: physiological, behavioral, cognitive, and social changes that occur throughout human life, which are guided by both genetic predispositions (nature) and environmental influences (nurture): birth-18 months: trust vs mistrust, 18 months-3 years: autonomy vs shame/ doubt. Child learns what he can or cannot control and develops a sense of free will: 3 years-6 years: initiative vs guilt. Child learns to be independent by exploring, manipulating, and taking action. Conception: occurs when an egg from the mother is fertilized by a sperm from the father. Ovulation: when the ovum, or egg, is matured and released into the fallopian tube. Zygote: when the 23 chromosomes are fused with the 23 from the sperm which creates the zygote which starts as a fertilized egg. Embryo: the zygote becomes an embryo when it is attached to the uterine wall. Amniotic sac: fluid-filled reservoir that the embryo lives in until birth.
