The psychological debate of nature vs. nurture is one that has been deliberated and refuted for many years. This debate is so controversial because although it is fact that genetic makeup does play a major role in developing a person, the nurture and environment in which a person is brought up in is also an important factor. The nature vs. nurture issue dates back to Ancient Greeks, through the times of Aristotle and John Locke, with each philosopher projecting their own individual thoughts on the matter. Although nature depicts the development of a person in terms of their appearance and certain personality traits, nature and the setting and situations in which a person grows up is more important in explaining the development of a person because ultimately a person is an overall reflection of the environment of which they were brought up in.
Psychologists are quick to support the nature debate because it deals with the genetic make-up of a person and biological psychology, which is fact. First of all, a person’s physical traits, such as eye color and blood type are genetically determined, even though there are certain ways to alter your look. Personality is proven to be heritable to an extent. Studies have proven that biological siblings are more similar in personality that adoptive siblings. In addition, a person’s genes can determine whether a person is predisposed to a disease or illness, such as diabetes and Alzheimer’s (Davies). A person who is affected with those types of diseases shows how nature can directly effect the development of an individual. A new technique called developmental genetic analysis is a procedure that examines the effects of genes throughout a person’s life. The technique concluded that a person’s intelligence is due about 50% to the genes they are born with (Huang). Furthermore, the nature debate is credible because of the genetic factors that support how people’s personalities and appearance develops, yet the nurture of a person ultimately overshadows the nature debate because environmental factors better influence the development of a person
Each person comes from different backgrounds, religions, and environments, which are all external factors that play a large role in the development of an individual. Diet, stress, prenatal nutrition, peer pressure, and television are just some of the more specific environmental factors that can affect a person. Clearly, there are many more aspects of the nurture debate that contribute to the argument that a person’s upbringing is what will influence their development. For example, NBC reported that in a study where teenagers played violent video games and non violent video games, the violent video games were proven to enhance emotion in the amygdale, or the center for fear and aggression (Kalning). In this case the emotional effect from the video games supports the nurture debate because normal teenagers with non violent behaviors and tendencies were affected by an outside force that has the potential of affecting the teenager’s personalities.
Nurture is more important in developing a person because despite a person’s genetic coding, the parents and the adults that a child is subjected to will play a greater role in the child’s development. Research shows that parents who talk to their children and spend time helping them interact ultimately raise more socially developed and intellectually stimulated children (Dewar). Even if a child born had genius parents, the environment and the early stages of development are crucial for the later stages of life. People are also highly influenced by their peers, and in the case of preschoolers who typically dislike a certain food will eat that particular food if children around them are eating it, showing that because it is the way of the human to want to fit and be liked, nurture has the greater impact and influence over a person (Harris).
