How do you test nature Vs nurture?
The traditional way of studying nature versus nurture relies on
twins
. Because identical twins share the same genetic code, comparing the health of twins can help determine whether genetic or environmental factors play more of a role in their health.
What psychologists studied nature Vs nurture?
Psychologist Francis Galton
, a cousin of the naturalist Charles Darwin, coined both the terms nature versus nurture and eugenics and believed that intelligence was the result of genetics.
What do twin studies tell us about nature Vs nurture?
The studies of reared-apart twins have shown that in general,
half the differences in personality and religiosity are genetically determined

how much parents read with their children and how well children learn to read appear to be related
. Other examples include environmental stress and its effect on depression.
Are psychological disorders nature or nurture?

both genetic and environment-related elements

Does nature or nurture determine intelligence?
This means that
a genetic basis for intelligence
is as much about one’s nurture as about one’s nature. Intelligence is the most widely studied trait in behavioural genetics. … Researchers have found a significant genetic contribution to intelligence differences using the method of heritability estimates.
How does nature and nurture affect child development?
In general,
nature looks at the impact of such physical approaches as neurotransmitters and genome sequencing
on child development, while nurture focuses on aspects such as peer pressure and social influences.
