Unit3C key terms


All of these key terms should be written out and defined in your own words, with a picture!

Unit IIIC - Genetics, Evolutionary Psychology, and Behavior

Brain Quiz - Gender Differences?
Some researchers say that men can have 'women's brains' and that women can think more like men.
Find out more about 'brain sex' differences by taking the Sex ID test, a series of visual challenges and questions used by psychologists in the BBC One television series //Secrets of the Sexes//:
  • Get a brain sex profile and find out if you think like a man or a woman.
  • See if you can gaze into someone's eyes and know what they're thinking.
  • Find out why scientists are interested in the length of your fingers.
  • See how your results relate to theories about brain sex.

Nature vs Nurture

Define these terms:







For each trait below, mark whether it is acquired through genetic (G) factors or through environmental (E). If you think the trait is acquired through the interaction of genetics and environment, mark it as GE

_extreme, repeated violence
_ schizophrenia
_ manic-depression
_ intelligence
_ shyness
_Alzheimer's disease
_ homosexuality
_ thrill seeking
_ dyslexia
_ nicotine dependence
_ hyperactivity

Explain how the environment and genetics could interact to produce the follpwing traits:
  1. alcoholism
  2. nicotine dependence
  3. obesity
  4. extreme violence
  5. intelligence

Genetic Revolution discussion questions:

1). If it were possible, would you want to take a genetic test telling you whcih diesases you are likely to suffer from later in life?

2). Suppose you or your partner are pregnant. Would you want the unborn child tested for genetic defects?

3). Do you think it should be legal for employers to use genetic tests in deciding whom to hire?
