EXPLAINING DIFFERENCES/ EXPLAINING SIMILARITIES NATURE VS NURTURE
QUESTION If it were possible, would you want to take a genetic test telling you which diseases you are likely to suffer from later in life? If you or your partner were pregnant- would you want the unborn child tested for genetic defects?
Biological determinism NATURE WHEN BIOLOGY DETERMINES CHARACTERISTIC'S
DOMINANT AND RECESSIVE GENES The Tower of London46 Books 23 donated by mother 23 donated by father Books are Chromosomes Chromosomes made from dna Genes are small areas of dna 30,000 genes per chromosome
DOMINANT VS. RECESSIVE GENES Dominant genes Characteristic is always present Recessive genes Two recessive genes must be paired in order for the characteristic to be present
CONSIDER DOLLY…. Would a human clone’s adult personality mimic the person donating the genetic code? or Would he/she be unique?
HEREDITY=WHEN BIOLOGY DETERMINES CHARACTERISTICS Genetic Predisposition Humans are born with a likelihood toward certain characteristics Does not mean “Born with” Usually needs something from the environment to activate- (diathesis-stress model) Common genetic predispositions….body weight-alcoholism- Alzheimer’s-Schizophrenia Genetic Determinism The idea that genes determine characteristics Genotype= “full” heredity Phenotype= “observed” properties Common genetic abnormalities.. Down Syndrome, Williams Syndrome, Color blindness, PKU
HOW DO GENES AND THE ENVIRONMENT INTERACT? PKU= Phenylketonuria Occurs when parents pass along a defective gene
How Similar Are We? How do we know?
The Minnesota Twin Study IDENTICAL TWINS REARED APART…
Characteristics more similar to biological parents.. With some exceptions.. Faith, values, manners, attitude. ADOPTION STUDIES
YOUR “GENETIC” OR “CORE” OF YOUR PERSONALITY IS YOUR TEMPERAMENT The Easy child The Difficult child The Slow-to-warm-up child What works best? Parent/Child-Goodness-of-fit
“Life is like a game of cards. The hand that is dealt you presents determinism; the way you play it is free will.” Nehru
Nurture THE ENVIRONMENT (AND OUR EXPERIENCES) SHAPE US…
NATURE ENABLES NURTURE AND NURTURE ENABLES NATURE Critical Period: An important time in development where development needs to happen or it will be delayed or dysfunctional Prenatal influences: German measles, birth defects, teratogens, fetal alcohol syndrome Culture: Establish their own norms
EXPERIENCE AND BRAIN DEVELOPMENT… IT’S COMPLICATED Impoverished Environment The Somerville Project Enriched Environment Abecedarian Project
BIG BOYS DON’T CRY!
HOW DOES NATURE AND NURTURE INTERACT TO DEFINE US AS MALE OR FEMALE? Gender Roles A set of expected behaviors for males and for females Gender Identity One’s personal sense of being male or female
