  1. Do Now: What event and/or person had the greatest impact on your development?

  2. Developmental Psychology The study of YOU from womb to tomb. We are going to study how we change physically, socially, cognitively and morally over our lifetimes.

  3. Nature Versus Nurture While going through this unit always been in the back of your head…. Are you who you are because of: • The way you were born- Nature. • The way you were raised- Nurture.

  4. Research Methods Cross-Sectional Studies Longitudinal Studies One group of people studied over a period of time. • Participants of different ages studied at the same time.

  5. Physical Development • Focus on our physical changes over time.

  6. Prenatal Development • Conception begins with the drop of an egg and the release of about 200 million sperm. • The sperm seeks out the egg and attempts to penetrate the eggs surface.

  7. The Zygote Stage One: Germinal Lasts about two weeks and consists of rapid cell division.

  8. Zygotes • Less than half of all zygotes survive first two weeks. • About 10 days after conception, the zygote will attach itself to the uterine wall. • The outer part of the zygote becomes the placenta (which filters nutrients).

  9. Genetic Abnormalities XO- Turner Syndrome XXY- Klinefelter Syndrome

  10. Stage 2: Embryonic Embryo • Lasts about 6 weeks. • Heart begins to beat and the organs begin to develop.

  11. Teratogens • Chemical agents that can harm the prenatal environment. • Alcohol (FAS) • Other STDs can harm the baby….. • HIV • Herpes • Genital Warts

  12. Stage 3: Fetal- Fetus • By nine weeks we have a… • Age of Viability- by about the 6th month, the stomach and other organs have formed enough to survive outside of mother. • At this time the baby can hear (and recognize) sounds and respond to light.

  13. Childbirth Click the woman in labor to watch a birthing video. Please be aware that it is graphic….beautiful but can be difficult to watch.

  14. Healthy Newborns • Turn head towards voices . • See 8 to 12 inches from their faces. • Gaze longer at human like objects right from birth.

  15. Reflexes Click on pictures to see clips of reflexes. • Inborn automatic responses. • Rooting • Sucking • Grasping • Moro • Babinski

  16. Maturation • Physical growth, regardless of the environment. • Although the timing of our growth may be different, the sequence is almost always the same. Click to see movie of Captain Marvel and his maturation.

  17. Developmental Norms- average age at which children perform various tasks

  18. Motor Development • Proximodistal Principle- development inward and then outward (infant can roll before walk or bring arms together) • Cephalocaudal Principle- development head to foot (infant can lift their head before being able to sit up)

  19. Motor Skills Gross Motor Skills Fine Motor Skills • Pre-representational- scribbles, focus is on activity itself • Representational- drawing means something to the child, 4 yr old can draw stick figures

  20. Secret Life of the Baby’s Brain •
