5 5 Developmental Issues, Prenatal Development, and the Newborn Overview  Three Major Developmental Issues  Conception and Prenatal Development  The Competent Newborn

6 6 Prenatal Development and the Newborn  Developmental Psychology  a branch of psychology that studies physical, cognitive and social change throughout the life span

7 7 Developmental Psychology IssueDetails Nature/Nurture How do genetic inheritance (our nature) and experience (the nurture we receive) influence our behavior? Continuity/Stages Is developmental a gradual, continuous process or a sequence of separate stages? Stability/Change Do our early personality traits persist through life, or do we become different persons as we age.

8 8 Prenatal Development and the Newborn Conception A single sperm cell (male) penetrates the outer coating of the egg (female) and fuses to form one fertilized cell. Lennart Nilsson/ Albert Bonniers Publishing Company

9 9 Prenatal Development  A zygote is a fertilized cell with cells that become increasingly diverse.  At about 14 days the zygote turns into an embryo (a and b). Zygote Embryo at 40 DaysEmbryo at 45 Days

11 11 Prenatal Development At 9 weeks, an embryo turns into a fetus (c and d). Lennart Nilsson/ Albert Bonniers Publishing Company

12 12 Prenatal Development and the Newborn  Teratogens  agents, such as chemicals and viruses, that can reach the embryo or fetus during prenatal development and cause birth defects Link to AM 12:20 Link to AM  Fetal Alcohol Syndrome (FAS)  physical and cognitive abnormalities in children caused by a pregnant woman’s heavy drinking  symptoms include misproportioned head

16 16 PKU - Phenylketonuria Recessive genetic condition where the child lacks an enzyme to break down phenylalanine Untreated, it can cause problems with brain development, leading to retardation, brain damage, and seizures

17 17 Infants are born with reflexes that aid in survival… Rooting - turning the head and opening the mouth in the direction of a touch on the cheek Grasping - curling the fingers around an object Stepping Reflex - reflex that causes newborns to start a stepping motion as they touch a surface
