Just like nature, nurture affects our mental health, as well.
While someone may have a genetic disposition for one condition or another, there still needs to be an environmental trigger for that condition to develop.
John Watson, one of the most well-known psychologists to propose environmental learning as the dominating factor in the nature versus nurture debate, feels that our behavioral traits are purely a result of our surroundings and experiences.
He felt that he could condition a new behavior in a child or alter an already existing behavior that is considered to be unfavorable (Sincero 2016).
Likewise, Chomsky believed that language is learned through the use of an innate language acquisition device that all humans are born with (Mc Leod 2007).
In addition, Freud speculated that traits like aggression are engrained in our DNA.
Science tells us that certain traits are most definitely attributed to genetic causes.
Our eye color, skin pigmentation, and certain diseases like Tay-Sachs or Huntingdon’s chorea are all direct results of the genes we inherit from our parents.
We each have a biological clock inside us that turns certain behaviors on and off in a way that is preprogrammed from birth.
An example of this would be the way our bodies change during puberty. Bowlby’s theory of attachment views the bond between the mother and child as being an innate process that aids in our survival as a species.
