Prologue: The Story of Psychology



READING GUIDEChapter 4: Nature, Nurture, and Human DiversityAt what age do we begin fearing strangers? Name at least 3 universal behaviors of humans.What is meant by the idea of “environmental influence.”BEHAVIORS GENETICS: PREDICTING INDIVIDUAL DIFFERENCES (134-143)1: What are genes, and how do behavior geneticists explain our individual differences?Genes: Our Codes for LifeDescribe the book analogy Myers uses for chromosomes, DNA, and genes. How many genes do you have? How does the environment affect these genes?How alike are we compared to chimps in terms of DNA? Do the differences that do exist matter? Why/how is it both wrong and right to say that height or personality traits are “controlled” by genes.Twin and Adoption StudiesWhy can’t we conduct an actual experiment of environment vs. heredity using humans?Identical vs. Fraternal TwinsWhy are identical twins genetically identical? What are the 2 qualifications to this?Compare fraternal twins’ genetic similarity to regular siblings’ genetic similarity. Why?Which type are the Olsen twins? If you didn’t answer it specifically above, what does it mean biologically to be “fraternal?”Risk of Alzheimer’s Disease: if 1 identical twin has it, other twin’s chance is ________%if 1 fraternal twin has it, other twin’s chance is ________%Risk of Divorceif 1 identical twin has been divorced, other twin’s chance is ________%if 1 fraternal twin has been divorced, other twin’s chance is ________%There’s obviously no “divorce” gene, so how could genes be the explanation for what you’re reading about the difference in divorce rates?Separated TwinsWho studied the Jim twins, what college, and which side of the Nature v. Nurture debate was supported by the study?What other types of similarities have Bouchard et al. found (1990) in separated twins?Biological vs. Adoptive RelativesWhat question do adoption studies allow us to ask?What’s the “stunning finding” concerning personalities of people who grow up together? Explain hypotheses as to why. What do parents influence in their children? What traits do adoptive parents seemingly give to their adopted children?Temperament and HeredityWhat does temperament allow us to predict about someone in the future? 2: What is heritability, and how does it relate to individuals and groups?Define heritability using the book’s definition. After reading this section, come back and put it in your words. What doesn’t heritability mean? Describe Mark Twain’s boys in barrels example and its lesson.Group DifferencesWhy are we taller and heavier as humans now than a century ago? Are height and weight heritabilities high or low? So, what exactly is heritability??? Be able to explain in your words!!Nature and NurtureWhat does it mean to say that genes are “self-regulating?” Explain the breastmilk example and then describe one more of your choice from the book.Gene-Environment InteractionDescribe on of the book’s examples of this interaction.The New Frontier: Molecular Genetics3: What is the promise of molecular genetics research?What’s the goal of molecular genetics?What psychological disorders can we test for high risk? What is the potential risk in making such tests readily available? EVOLUTIONARY PSYCHOLOGY: UNDERSTANDING HUMAN NATURE (143-149)4: How do evolutionary psychologists use natural selection to explain behavior tendencies?How are evolutionary psychologists different from behavior geneticists?Summarize/paraphrase Darwin’s main points of natural selection. Natural Selection and AdaptationWhat animal did Belyaev work with, what did he do to them, and how’d he do it?Evolutionary Success Helps Explain SimilaritiesRead very carefully the first full paragraph on pg. 145. Do you comprehend the big idea!? If you do, explain why losing all people except the Icelanders or Kenyans would only minimally reduce the diversity of the human genome. If you don’t get it, keep reading/thinking until you get it.Outdated TendenciesWhy do we like sweet food so much? Why hasn’t natural selection removed this preference from us?Evolutionary Psychology TodayPick one of the questions that are listed concerning what evolutionary psychologists study today. Answer the question using an evolutionary psychology perspective/explanation (give it a try!).An Evolutionary Explanation of Human Sexuality5: How might an evolutionary psychologist explain gender differences in mating preferences?Gender Differences in SexualityWhich gender seems to be more sexually inclined no matter what question you ask?Casual sex: _____ % of males; _____ % of femalesOk with the idea of multiple partners: _____ % of males; _____ % of femalesAre gay men more like males or females concerning how much they think about sex?What type of males are most likely to engage in casual, impulsive sex?Describe the design/results of the 1978 Florida State study.What do men think when encountering casual conversations involving warm responses by a female?Natural Selection and Mating PreferencesExplain how men and women’s mating preferences differ and why.List some qualities of attractiveness from men’s perspective. Women’s.Critiquing the Evolutionary Perspective6: What are the key criticisms of evolutionary psychology?Why is starting with an effect and working backward a problem? Describe a social consequence of evolutionary psychology.PARENTS AND PEERS (149-153)7: To what extent are our lives shaped by early stimulation, by parents, and by peers?We aren’t blank slates, we are…Parents and Early ExperiencesExperience and Brain DevelopmentDescribe the experiment involving rats and varying types of environments. Results? What is “handling” and what are its effects?Describe the pruning process our brains go through and when/why this happens.How Much Credit (or Blame) Do Parents Deserve?Use “hindsight bias” from Ch 1 to explain why as a society put so much weight into what parents do as parents to their kids.Do you blame your parents for any of your faults? Why? After reading this, why should you maybe reconsider this line of thinking.Peer InfluenceSummarize the conclusions of the bullets:Preschoolers and food:Children’s accents:Teens and smoking:CULTURAL INFLUENCES (153-159)8: How do cultural norms affect our behavior?Define Culture. Name 1 culture you’re a part of and list a few qualities of that culture.Variation Across CulturesWhat are norms? Give 1 book example and give 1 unique norm.What is personal space? Which cultures need less? More? Anyone out there watch Seinfeld? Close talkers?Variation Over TimeGive at least 2 American cultural changes over the last decade (yes, come up with these on your own!).Culture and the Self9: How do individualist and collectivist cultural influences affect people?Where are individualistic cultures found? Collectivist? Give a few examples of the behavioral differences between people from these different types of cultures.How do the cultures differ in how they use their languages? (bottom of 156) WHY do you think this difference exists?Culture and Child-RearingHow has the message we teach children changed in the last century?Describe the differences in where children sleep.Developmental Similarities Across Groups Compare perceived differences to actual differences in personality traits across cultures.GENDER DEVELOPMENT (159-166)How is gender different than biological sex?Gender Similarities and Differences10: What are some ways in which males and females tend to be alike and to differ?Compare men and women’s self-esteem ratings.Describe the following differences:Age of puberty onset:Life expectancy:% body fat:% body muscle:Height:Sexual arousal following orgasm:Sense of smell for faint odors:Emotional expression:Get help from others:Risk of depression and anxiety:Risk of eating disorders:Suicide:Alcohol dependence:Diagnosis of autism, color-blindness:ADHD:Anti-social personality disorder (sociopath):Gender & AggressionMen are generally considered more aggressive for what kind of aggression?

What is the male answer syndrome? Give the question they asked the participants.Describe ways women are more interdependent than males.Describe gender differences in religiosity.When do these gender differences peak? When do they become more similar?The Nature of Gender11: How do nature and nurture together form our gender?What is the biopsychosocial perspective?Which parent determines your biological sex? Why/how? A very important single gene on the Y chromosome contain the instructions for producing what vitally important male hormone? Do females have this hormone? When does the development of male sex organs begin?What important activity happens during the 4th and 5th prenatal months? Describe some of the actual differences that emerge as a result of this time period.What happens when there is hormone malfunction (too much or too little hormone)?What happened to Brenda Reimer? Does this suggest nature or nurture matters more for gender development?The Nurture of GenderGender RolesGive some personal examples of what you think of when you think of men and women’s gender roles.Describe actual differences in work time and household/caregiving time. What cultures offer the greatest gender equity? The least? How many and which countries granted women’s suffrage (right to vote) by the year 1900? Gender & Child-RearingWhat’s the difference between gender identity and gender typing?What does social-learning theory predict about gender development?REFELECTIONS ON NATURE AND NURTURE (166-169)Why has brute strength become less important in our society? Are differences in gender roles converging or widening? Why/how?What percent of U.S. adults, “do not believe in evolution’s role in ‘how human beings came to exist on Earth’?”Why do you think people feared Newton’s explanation of the rainbow or Galileo’s claim that the Earth was revolved around the sun?What is your opinion on evolution and natural selection? Do you believe Myers comparison of Darwin’s theory to Newton and Galileo? Will evolution and the creation of the universe and man through natural processes eventually be seen as common sense or not? I’m very interested to hear your intelligent thoughts on this! ................
