1. DEVELOPMENT CHAPTERS 3 AND 4

2. Genome Genome is the set of complete instructions for making an organism, containing all the genes in that organism.

3. Twins and Procedures Behavior geneticists study effects of shared and unique environments on total or partial genetic makeup.

4. Adoption Studies Adoption studies, as opposed to twin studies, suggest that adoptees (who may be biologically unrelated) tend to be different from their adoptive parents and siblings.

5. Temperament Studies Temperament refers to a person ’ s stable emotional reactivity and intensity. Identical twins express similar temperaments, suggesting heredity predisposes temperament.

6. Heritability Heritability refers to the extent to which the differences among people are attributable to genes.

7. Group Differences If genetic influences help explain individual diversity in traits, can the same be said about group differences? Not necessarily. Individual differences in weight and height are heritable and yet nutritional influences have made westerners heavier and taller than their ancestors were a century ago.

8. Nature and Nurture. Genes provide choices for the organism to change its form or traits when environmental variables change. Therefore, genes are pliable or self-regulating.

9. Experience and Brain Development Early postnatal experiences affect brain development. Rosenzweig et al. (1984) showed that rats raised in enriched environments developed thicker cortices than those in impoverished environment.

10. Culture and the Self If a culture nurtures an individual ’ s personal identity, it is said to be individualist, but if a group identity is favored then the culture is described as collectivist. Kyodo News

11. Culture and the Self

12. Gender Roles Our culture shapes our gender roles — expectations of how men and women are supposed to behave. Gender Identity — means how a person views himself or herself in terms of gender.

13. Gender Roles: Theories Gender Schema Theory suggests that we learn a cultural “ recipe ” of how to be a male or a female, which influences our gender- based perceptions and behaviors. Social Learning Theory proposes that we learn gender behavior like any other behavior — reinforcement, punishment, and observation.

D. there is very little you can do to override the power of your genes in influencing your weight.

31. Developing Through the Life Span Chapter 4

32. 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.

33. Maturation The development of the brain unfolds based on genetic instructions, causing various bodily and mental functions to occur in sequence — standing before walking, babbling before talking — this is called maturation. Maturation sets the basic course of development, while experience adjusts it.

34. Cognitive Development Piaget believed that the driving force behind intellectual development is our biological development amidst experiences with the environment. Both photos: Courtesy of Judy DeLoache

35. Schemas Schemas are mental molds into which we pour our experiences.

36. Piaget ’ s Theory and Current Thinking

37. Theory of Mind Preschoolers, although still egocentric, develop the ability to understand another ’ s mental state when they begin forming a theory of mind.

38. Origins of Attachment Harlow (1971) showed that infants bond with surrogate mothers because of bodily contact and not because of nourishment. Harlow Primate Laboratory, University of Wisconsin

39. Origins of Attachment Like bodily contact, familiarity is another factor that causes attachment. In some animals (goslings), imprinting is the cause of attachment. Alastair Miller

40. Attachment Differences Ainsworth Placed in a strange situation, 60% of children express secure attachment, i.e., they explore their environment happily in the presence of their mothers. When their mother leave, they show distress. The other 30% show insecure attachment. These children cling to their mothers or caregivers and are less likely to explore the environment.

41. Insecure Attachment Harlow ’ s studies showed that monkeys experience great anxiety if their terry-cloth mother is removed. Harlow Primate Laboratory, University of Wisconsin

42. Self-Concept Self-concept, a sense of one ’ s identity and personal worth, emerges gradually around 6 months. Around 15-18 months, children can recognize themselves in the mirror. By 8-10 years, their self- image is stable. Laura Dwight

43. Child-Rearing Practices PracticeDescription Authoritarian Parents impose rules and expect obedience. Permissive Parents submit to children ’ s demands. Authoritative Parents are demanding but responsive to their children.

44. Frontal Cortex During adolescence, neurons in the frontal cortex grow myelin, which speeds up nerve conduction. The frontal cortex lags behind the limbic system ’ s development. Hormonal surges and the limbic system may explain occasional teen impulsiveness.

45. Developing Morality Kohlberg (1981, 1984) sought to describe the development of moral reasoning by posing moral dilemmas to children and adolescents, such as “ Should a person steal medicine to save a loved one ’ s life? ” He proposed stages of moral development. AP Photo/ Dave Martin

46. Moral Thinking Preconventional Morality: Before age 9, children show morality to avoid punishment or gain reward. Conventional Morality: By early adolescence, social rules and laws are upheld for their own sake. Postconventional Morality: Affirms people ’ s agreed-upon rights or follows personally perceived ethical principles.

47. Social Development

48. Aging and Intelligence Longitudinal studies suggest that intelligence remains relative as we age. It is believed today that fluid intelligence (ability to reason speedily) declines with age, but crystalline intelligence (accumulated knowledge and skills) does not.

49. Reflecting on Piaget ’ s Theory Piaget ’ s stage theory has been influential globally, validating a number of ideas regarding growth and development in many cultures and societies. However, today ’ s researchers believe the following: Development is a continuous process. Children express their mental abilities and operations at an earlier age. Formal logic is a smaller part of cognition.

50. Assimilation and Accommodation The process of assimilation involves incorporating new experiences into our current understanding (schema). The process of adjusting a schema and modifying it is called accommodation. Jean Piaget with a subject Bill Anderson/ Photo Researchers, Inc.

51. Developing Reasoning Power According to Piaget, adolescents can handle abstract problems, i.e., they can perform formal operations. Adolescents can judge good from evil, truth and justice, and think about God in deeper terms. William Thomas Cain/ Getty Images AP/Wide World Photos
