Unformatted text preview: 6 Developmental Psychology Issue Details Nature/Nurture How does our genetic inheritance ( nature ) and our experience ( nurture ) influence our behavior and development? Continuity/Stages Is development a gradual, continuous process of adding on more of the same type behavior? Or is it a stage development in which there is a sequence of separate, abrupt changes to a new type of behavior? Stability/Change Do our early personality traits persist through life or do we become different persons with different personalities as we age? Does our intelligence change as we age or does it remain stable? 7 Prenatal Development and the Newborn How, over time, did we come to be who we are? From zygote to birth, development progresses in an orderly, though fragile, sequence. The timing of developmental milestones may differ between individuals, but the sequence varies very little. The sequence is universal, but the timing is a function of individual maturation and culture. Prenatal Development Zygote: the period from conception to 2 weeks. Embryo : the period from 2 weeks to 8 weeks. Fetus : the period from 9 weeks to birth. In general, boys and men have more physical and mental problems compared to girls and women. Also, males are more likely to spontaneously abort at every stage of prenatal development. At Conception Birth Number of Boys: 120 – 150 106 Number of Girls: 110 – 120 100 9 10 Prenatal Development Zygote: the period from conception to 2 weeks. A zygote is a fertilized cell with 100 cells that become increasingly diverse. Cell division is the primary task. Embryo : the period from 2 weeks to 8 weeks. At about 14 days, the zygote turns into an embryo (pictures a and b). This is very vulnerable time due to rapid growth. Organs are being formed and are beginning to function. 11 Prenatal Development At 9 weeks, an embryo turns into a fetus (c and d). This period lasts 30 weeks and is a time of “ growth and finishing.” Teratogens are chemicals or viruses that enter the placenta and harm the developing fetus. A teratogen is any envirnomental agent that causes birth defects. It can cause physical and/or cognitive abnormalities (teras is Greek for monster).

Habituation is decreasing responsiveness with repeated stimulation (getting “used to” the new stimulus).to” the new stimulus)....
