Document Summary
Developmental psychology: the study of how humans change over the lifespan. (thoughts, emotions, personality, physiology). Post-hoc fallacy: logical error where you assume a caused b, only because a came before b. Development influences experiences, while experiences also influence development. Is there something special about this group of people: the flynn affect is an example of cohorts. Nature vs nurture: children can seek out or create environments which support their genetic predispositions. Gene expression: genes can be turned on/off due to experiences. Germinal stage: zygote divides many times to form a blastocyst. Embryonic stage: middle of week 2, cells assume different functions and an embryo forms: lasts until week 8. Fetal stage: start of week 9: major organs have developed, physical maturation is last remaining goal. Brain development: forms at day 18, undergoes proliferation until 6 months of pregnancy, neutrons sort themselves out beginning at 4 months.
