  1. Environmental Influences on Behavior

  2. Types of Environmental Influences

  3. How Much Credit ( or Blame ) Do Parents Deserve? • You and your siblings grow up in the same environment, are you all the same? • Parents effect your belief systems and values much more than your personality. • Parents take too much credit for success and too much blame for failures. • Extreme environmentalism can be VERY dangerous, why? Are children clay to be molded by their parents?

  4. Lets look at perhaps our first environmental influence…. Prenatal Environment

  5. Two Placental Arrangements in Identical Twins

  6. Experience and Brain Development I spend a lot of $$$ sending Sammy to pre-school. They just play with a lot of toys. I could use that $$$ for a whole lot of PS2 games. Is it money well spent?

  7. Brain cells is an impoverished environment.

  8. Brain cells in an enriched environment.

  9. What does this mean for humans? • If children from impoverished environments given stimulating infant care, they score better on intelligence tests by age 12 than counterparts. Use it or lose it

  10. A Trained Brain A well-learned finger-tapping task activates more motor cortex neurons (right) than were active in the same brain before training (left)

  11. Perhaps the biggest environmental influence, at least by your age may be…. Peer Influence • I can’t get Sammy to clean up his toys, but when he sees his friends clean up in school, he jumps to it. • “Selection effect” we seek out people with similar interests- that may explain why we seem to conform to our peers.

  12. Culture • Behaviors, attitudes, traditions etc… of a large group that have been passed down from one generation to the next.

  13. Greetings exercise Cultural Variations • To understand how cultures effect who we are it is important to recognize our cultural norms: an understood rule for acceptable behavior. • Individual v. Collectivistic Cultures • Why is it so hard to identify our own cultural norms?

  14. Variations over Time • Different generations of the same culture may also have differing norms.

  15. Memes • self-replicating ideas, fashions or innovations passed from person to person. Budweiser Frogs Where’s the Beef Lady. Toys R Us Theme Song

  16. Gender • We already know the nature differences. • XX v XY • But that focuses on SEX: • We are going to discuss GENDER: What is the difference?

  17. Gender Roles • A set of expected behaviors for males and females • List some of your gender roles. What gender role is she breaking?

  18. Changing Attitudes about Gender Roles

  19. Gender Identity • Our own sense of male or female. • Personalized to us • We realize our gender identity through gender-typing: acquiring our gender identity.

  20. Two Theories of Gender-typing

  21. Social Learning Theory Lets use Sammy as an example.

  22. Social Learning Theory I play Baseball. Sammy imitates my behavior. I reward Sammy. I punish Sammy. Sammy’s Mom puts on makeup. Sammy copies her.

  23. Gender Schema Theory • Schema: a concept or framework of how we organize information. • Develop schemas for gender. • See the world through the lens of your gender schemas. Boy’s don’t do this, that’s for girls. Yeah, that’s cool!!!! I want to do that.
