|Correlation of traits in twins, sibling, and adopted siblings.|
In the study of Developmental Psychology the question: "How do Nature and Nurture interact to cause Development?" is asked about every single finding, idea, and concept you can imagine.
For those not familiar with these ideas here are the basics:
-Nature refers to our biological/genetic inheritance. More specifically if refers to our genes and all the traits and features associated with our genome.
-Nurture refers to the physical and social environment that influence our development.
An error when thinking about nature and nurture is to ask if either nature of nurture is responsible for a certain aspect of development. This is an error because every characteristic that we have is created through an interaction of our genetics and our environment. In the graph above we can see that some traits are highly correlated with genetics (twins). In the same graph we can also see that certain traits hive high correlation even among adoptive siblings who do not share genetics but share a similar environment.
