There has always been a large controversy over whether
inherited genes or the environment influences and effects our
personality, development, behavior, intelligence and ability. This
controversy is most often recognized as the nature verses nurture
conflict. Some people believe that it is strictly genes that effect our
ways of life, others believe that it is the environment that effects us,
and some believe that both of these influence our behavior. Either way,
social scientists have been struggling for centuries deciding whether
our personalities are born or made. Tests are done often on identical
twins that were separated to see how they are each influenced by their
separate environments.
In the past twenty years, it has been discovered that there is a
genetic component to every human trait and behavior. However, genetic
influence on traits and behavior is partial because genetics account on
average for half of the variation of most traits. Urie Bronfrenbrenner,
who studies genetics, said, “It is not nature vs. nurture, but the
interaction of nature and nurture that drives development.” Researchers
are finding that the balance between genetic and environmental
influences for certain traits change as people get older. Also, people
may react to us in a certain way because of a genetically influenced
personality and, we may choose certain experiences because they fit best
with our instinctive preferences. This means that our experiences may
be influenced by our genetic tendencies. One way researchers study the
development of traits and behaviors is by measuring the influence of
genetics through out ones life span, and it is found to be that the
genetic influence on certain trait increase as people age. A research
was done to see whether a trait would show up in a child if it was
environmentally influenced or genetically influenced. A child was given
more negative attention than another was, and it increased the chances
of the child having depressive symptoms and anti-social behavior. But
these symptoms disappeared when accounted for genetic influences and how
parents treat their children.
There are three types of gene/environment relations. The first
one is called a passive correlation. It is to be explained as, for
example, if a musical ability was genetic, and a child was passed a
musical ability trait, than the child would most likely have musically
inclined parents. Their parents then would provide them with the genes
and environment to promote the development of that ability. The second
one is called evocative. This happens when genetically distinct people
evoke different reactions from peers and parents and others. And the
third association is called an active correlation. This is when people
actively select experiences that fit with their genetically
