Significant Studies in for the Nature
Nurture Debate
Skodak and Skeels (1030-1940s) - correct answer ✔139 children placed up
for adoption before the age of 6 months in Iowa. The children were adopted
from poor mothers with low education and IQ scores. It was found that
adopted children had higher IQ scores which seemed to be an environmental
effect but their scores were correlated .31 with bio mothers and 0 with that of
adopted parents.
Tuskegee Syphilis Experiment (1932-1972) - correct answer ✔An
experiment studying the effect of untreated Syphilis on African-American men.
It was led by three UVA graduates.
Shilf and Lewontin (Separated Siblings) - correct answer ✔20 pairs of half
siblings were separated, one was adopted and the other remained with the
biological mother. This study selected for large environmental differences.
Adopted children had a mean IQ of 108.9 while children who remained with
their biological parents had a mean IQ of 98.
Capron and Duyme (1989) - correct answer ✔Cross fostering study which
identified adopted children in four groups to compare their IQs. These groups
compared the IQ score of biological parents and adoptive parents, showing
that generally if any parent has a higher IQ, so will the child.
Kendler, Turkheimer, et al. (2014) - correct answer ✔A Swedish population
study of separated brothers in adopted vs. biological homes. Adopted brothers
had IQs 4.4 points higher than their siblings who stayed in the home with their
biological parents. Adopted half brothers had an IQ 3.2 points higher than
their siblings in the home with their biological parents.
