PSYC 2000 Study Guide - Zygote, Fetus, Asthma
Document Summary
Developmental psychology- age-related changes in behavior/mental processes form conception to death. Interactionist perspective- relations and contributions from each side c. Testing 20 year-olds would do better than 80 year-olds: longitudinal studies are expensive, both in time and money. Prenatal development: germinal period- 1st two weeks after conception creation of zygote (fertilized egg), cell division, and attachment of zygote to uterine wall, embryonic period- 2-8 week after conception. Rate of cell division increases, support systems for cells form, and organs appear. Fetus is rapidly gaining weight; fine detailing of body organs and systems. Teratogen- an agent that produces a malformation or raises population incidence of malformation. Severity of damage dependent of 3 factors: dose response, time of exposure- certain stages of development are more vulnerable than others. 1st trimester more vulnerable than 2nd or 3rd trimesters: genetic susceptibility- genotype of pregnant woman and genotype of fetus.
