1. Evolutionary Psychology Sometimes humans can get only so far…

2. What is the difference between behavior geneticists and evolutionary psychologists?

3. Evolutionary Psychology Aims to find out what makes humans ALIKE –Natural selection and the development of human characteristics

4. Natural selection Among the range of inherited trait variations, those that lead to increased reproduction and survival will most likely be passed on to succeeding generations

5. Why do we love fats and sweets? MUST LOOK AT ORIGINAL PURPOSE Once hard to come by, they helped us survive famine long ago –Natural disposition is mismatched with today’s junkfood environment

6. Mutations Nature selects beneficial variations among mutations: random errors in gene replication

7. Can you identify gender differences in sexuality and mating preferences – AND describe the evolutionary explanations for those differences?

8. Gender Biologically and socially influenced characteristics by which people define male and female

9. Men vs. Women Sex? –Relational or recreational? –Masturbation practices? –Social and economic status preference vs. health?

10. Criticisms of Evo. Psych Starts with the EFFECT with aims to work backwards to propose explanation –What’s wrong with this? Which type of reasoning is this? Effects of culture? Explanation doesn’t help us necessarily overcome human behavior –Males and cheating – the promiscuity gene

11. Parents/Peers/Culture

12. How can experience modify the brain? Embryos receive different nutrition and varying exposure to toxic agents Normal stimulation in early years is critical for optimal brain development

13. maturation Biological growth process that enable orderly changes in behavior, relatively uninfluenced by experience –Ex: a flower unfolds due to its genetic instructions, we do the same through maturation Humans sit up, then crawl, then stand up, then walk

14. Maturation sets the basic course, but experience adjusts the direction After brain maturation provides humans with abundance of neural connections, experience preserves our activated connections and unused connections degenerate –Called pruning

15. What roles do parents play in development?

16. What roles do our peers play in development?

17. How’d you do? Parents –Education –Discipline –Responsibility –Orderliness –Charitableness –Interacting with authority figures Peers –Cooperation –Finding road to popularity –Inventing styles of interaction among people of same age

18. Conclusion Parents can influence the culture that shapes the peer group by helping select children’s neighborhood and schools, thus providing the peer group for the children to interact with.

19. Cultural Influences Culture: behaviors, attitudes, values and traditions shared by a group of people transmitted from one generation to the next

20. Norms Rules that govern the culture’s members’ behaviors –sometimes oppressive, but they help progress society –Vary in personal space, expressiveness, and pace of life –Colliding cultures make differing norms interaction uncomfortable – why?

21. Effects of Time Culture changes faster than genetics’ abilities to keep up –What kind of issues can this cause? Women and abusive relationships Increased rights for minorities Rates of divorce, delinquency and depression

22. Individualist vs. Collectivist Individualist –Value personal achievement and fulfillment –Individual rights and liberties –Define identity in personal traits –Strive for personal control in life Collectivist –Value group goals and solidarity –Relationships tend to be closer and enduring –Maintaining social harmony is important –Identity is derived from belonging

23. Conclusions Individualist cultures encourage ________________ in their children, while collectivist cultures focus on __________________________ Children in collectivist grow up with a stronger sense of family self
