2. Embryonic and Fetal Periods
embryonic period Period of prenatal development during which major biological organs and systems form; begins about the tenth to fourteenth day after conception and ends about the eighth week after conception. fetal period Period of prenatal development, from about the eighth week after conception to birth, marked by rapid growth and preparation of body systems for functioning in the postnatal environment.

4. Teratogens (textbook p. 120)
Problems during prenatal development can occur due to genetic abnormalities or environmental toxins called teratogens.
Every major system is in place during prenatal development by the end of the embryonic stage and refinement of the systems takes place during the fetal stage, which is the longest.
May be temporary or permanent.
Teratogen or not?

Nutrition
Home visits
Early identification and treatment of developmental delays
Speech therapy
Occupational therapy

13. How do researchers determine if an attribute is due to Nature or Nurture?

14. What do you think researchers found in their twin studies about most disorders? Are they due more to Nature or Nurture? ? ?

15. Nature! Most disorders have a genetic basis.

16. Nature or Nurture?

17. Nature!
Temperament
Stable, early-appearing individual attributes which includes sociability, emotionality, and activity level
