Nativists, those who believe that every characteristic we have is determined only by nature, assume that the characteristics of the human species as a whole are simply a product of evolution and that the things that make us unique are a result of our own specific genetic code.
They believe that the characteristics that are not observable at birth, such as personality traits, emerge later as the product of maturation.
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).
Our cognitive development is dependent on the environment and civilization in which we are reared (“Nature vs. Bandura’s social learning theory states that aggression is a characteristic that we learn through observation and imitation.
In addition, Skinner believed that language is something individuals learn from others via behavioral shaping techniques.
Often times, these twins will share behavioral traits as if they were raised together in the same place.
Mental health is undoubtedly affected by our biological dispositions.
