blueprint:2: how do we know that DNA makes us who we are- My notes

Today I read about a third of the chapter. The author describes two studies that he founded regarding heritability. The first study is CAP (Colorado Adoption Project and TEDS (Twins Early Development Study).

CAP

• He studied 250 adopted children.
• Genetic, Environmental and Both type of parents
• Children were analyzed at ages 7, 12, 16 in a lab and phone interviews in-between. The children are now in their 40s and still being studied.
• The results showed genetic influence on intelligence, verbal and spatial ability, memory , reading and temperament

TEDS

• UK
• Studied DZ (dizygotic) and MZ (monozygotic) twins. (Fraternal and Identical)
• Home visits, tests completed by parents and then online tests
• The results showed substantial heritability on lack of empathy, disregard for others, hyperactivity and inattention

Terms

• Variance- The extent to which people differ
• Covariance — Index of similarity
• Correlation .1= small, .3 moderate, .5 substantial
