People’s divorce risks are about 50% attributable to genetic factors• 3. Adoptees’ traits bear more similar to their adoptive parents than to their biological parents• 4. Two different children in the same family are on average as different from one another as are pairs of children selected from the general population
  3. 3. Nature vs. Nurture Quiz cont• 5. If after a worldwide catastrophe only Icelanders and Kenyans survived, the human species would soon be just as mixed and diverse as it is now• 6. A child who hears English spoken with one accent at home and another in the neighborhood or at school adopts the accent of their peers, not their parents• 7.

  5. 5. Heredity vs. Environment• Heredity- characteristics obtained directly from the genes• Environment- person’s surroundings (which influence a person’s characteristics)
  6. 6. Genetics • Every human cell contains 46 chromosomes (23 pairs). • Made up of deoxyribonucleic acid- DNA. • Made up of Genes. • Made up of nucleotides.
  7. 7. Twins • Best way to really study genetics because they come from the same zygote. • Bouchard Study • .69 Correlational coefficient for IQ tests of identical twins raised apart. • .88 raised together.
  8. 8. Chromosomal Abnormalities• Gender comes from 23rd pair of chromosomes…men have XY…woman have XX.• Turner’s syndrome is single X.• Klinefelter’s syndrome is extra X…XXY• Down syndrome….extra chromosome on 21st pair.

  11. 11. Physical Development• Focus on our physical changes over time.
  12. 12. 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.
  13. 13. • Once the sperm penetrates the egg- we have a fertilized egg called…….. The Zygote The first stage of prenatal development. Lasts about two weeks and consists of rapid cell division.
  14. 14. 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).
  15. 15. After two weeks, the zygote develops into an…. Embryo • Lasts about 6 weeks. • Heart begins to beat and the organs begin to develop.
  16. 16. Fetus • By nine weeks we have a… • The fetus 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.
  17. 17. Teratogens • Chemical agents that can harm the prenatal environment. • Alcohol (FAS) • Other STDs can harm the baby….. • HIV • Herpes • Genital Warts
  18. 18. Childbirth

  22. 22. Bellringer #2• List 3 things you think about when you hear maturation.
  23. 23. Maturation • Physical growth, regardless of the environment. • Although the timing of our growth may be different, the sequence is almost always the same.
  24. 24. Puberty• The period of sexual maturation, during which a person becomes capable of reproducing.
  25. 25. Primary Sexual Characteristics • Body structures Penis that make reproduction Testes possible. Vagina Ovaries
  26. 26. Secondary Sexual• Non- Characteristics reproductive sexual Body Hair characteristics. Widening of the Hips Deeper Voice Breast Development
  27. 27. Landmarks for Puberty• Menarche for girls.• First ejaculation for boys.

  29. 29. Adulthood• Then its all goes downhill.
  30. 30. Physical Milestones • Menopause
  31. 31. Life Expectancy• Life Expectancy keeps increasing- now about 75.• Women outlive men by about 4 years.• But more men are conceived 126 to 100. Then 105 to 100 by birth. In other words, men die easier.

  41. 41. Stage Theorists• These psychologists believe that we travel from stage to stage throughout our lifetimes.
  42. 42. Sigmund Freud• We all have a libido (sexual drive).• Our libido travels to different areas of our body throughout our development.• If we become preoccupied with any one area, Freud said we have become fixated on it.• Together Freud called these stages our Psychosexual Stages of Development.
  43. 43. Oral Stage • Seek pleasure through out mouths. • Babies put everything in their mouths (0-2). • People fixated in this stage tend to overeat, smoke or have a childhood dependence on things.
  44. 44. Anal Stage• Develops during toilet training (2-4).• Libido is focused on controlling waste and expelling waste.• A person fixated may become overly controlling (retentive) or out of Click to see a classic example of anal retentive and anal expulsive behaviors. control (expulsive).
  45. 45. Phallic Stage • Children first recognize their gender (4-7). • Causes conflict in families with the Oedipus and Electra Complexes. • Fixation can cause later problems in relationships.

  62. 62. Accommodation• Changing an existing schema to adopt to new information. If I tell someone from the mid-west to picture their schema of the Bronx they may talk about the ghetto areas. But if I showed them other areas of the Bronx, they would be forced to accommodate (change) their schema to incorporate their new information.

  68. 68. Criticisms of Piaget• Some say he underestimates the abilities of children.• Information- Processing Model says children to not learn in stages but rather a gradual continuous growth.• Studies show that our attention span grows gradually over time.
  69. 69. Types of Intelligence Crystallized Intelligence Fluid Intelligence• Accumulated knowledge. • Ability to solve• Increases with age. problems quickly and think abstractly. • Peaks in the 20’s and then decreases over time.
  70. 70. Moral DevelopmentThree Stage Theory by Lawrence Kohlberg!!!
  71. 71. Pre-conventional Morality• Morality based on rewards and punishments.• If you are rewarded then it is OK.• If you are punished, the act must be wrong.
