Document Summary

4 broad issues that guide developmental research: nature vs nurture, critical vs sensitive periods. Critical period: age range that experience must occur for development to proceed normally. Sensitive period: optimal age range for certain experiences: continuity vs discontinuity. Development continuous and gradual or go through distinct stages: stability vs change. Research these issues by plotting developmental functions performance with age. Cross-sectional design: research design that simultaneously compare people of different ages at particular point in time: problem with this is different age groups grew up in different periods. Sequential design: combines cross-sectional and longitudinal approach: test several age groups as grow older and see if they follow similar developmental pattern, but most time-consuming and costly. 3 stages: germinal stage: first 2 weeks of development. Sperm fertilizes egg: embryonic stage: 2 week 8 week. Placenta and umbilical cord develop at start of stage. Placental contain membranes that allow nutrients to pass from mother"s blood to umbilical cord.
