The nature verses nurture debate analyzes genetics and environmental components that contribute to the evolution of one’s self. Both environmental surroundings and inherited genes contribute to the development of individuals. This debate exist due to inexplicit scientific findings and societies urge to uncover why people are the way they are. Scientific research indicates that an individual’s genetic makeup or physical properties are determined by a combination ratio of recessive and dominant geneo and phenotypes. This process of DNA coding plays a key role in an individual’s physical appearance, medical conditions, and addictions. Sarah Mae Sincero, author of Nature and Nurture Debate, further speculates if genetics are a factor in determining
other human characteristics such as, personality traits, intelligence or sexual orientation (pg. 1). In my opinion scientist are most attentive in resolving the nature verses nurture debate. Discovering what makes people tick and why people are who they are will provide significant insight to other components linked to humanity. A conclusive resolution of nature verses nurture theory could negatively impact society. If it is concluded that nature preemptively determines who we are and what we do then people will not be held accountable for their actions and will be a product of their genetic makeup. It could further be proposed that genetics are responsible for an individual’s actions. This brings to mind the insanity plea. An Insanity plea suggest an individual’s inability to cognitively use brain capacity to employ logic or reason and due to such imbalances, should not be held accountable for ones actions or demeanors. Genetics would be used in the same manner. In the same token if everyone was a product of their environment people would not strive to be more than what there environment allocated them. For example if my mother was undereducated and poor then I too would grow up to be undereducated and poor. This mentality would limit people and society. It is clearly evident that neither solely nature or nurture are the foundation for who people are and what they do, but rather what decisions and actions an individual employs despite ones genes or environmental situations.
In the well-received novel “Pudd’nhead Wilson,” Mark Twain skillfully addresses the ancient argument about the origin of one’s character and whether it’s derived from his nature or his surroundings. We can best see this battle between nature versus nurture by inspecting the plot lines that follow the characters Thomas a Becket Driscoll, Valet de Chambre, and Roxana the slave. Thomas was born into a wealthy white family while Roxy birthed Chambers into a life of slavery. It seemed as though each would have gone their separate ways into opposite walks of life, but Roxy secretly swapped the children, which destined each to their counterintuitive fates. Through their words and actions, Tom, Chambers, and Roxy have proven the idea that one’s behaviors and desires are a result of his upbringings and the environment he lives in rather than by his innate nature.
Have you ever thought about whether the way you are is based on your genetic makeup? Do you believe our environment shapes us into who we are, instead? In the psychology debate of nature versus nurture, I believe that nurture plays a big role in who
Susan Evers and Sharon McKendrick, the famous identical twins from the movie The Parent Trap, were separated at a young age by their divorcing parents. Sharon grew up in Boston to a socialite mother while Susan grew up in California on her father’s ranch. Sharon had structure while Susan’s life was very laid back. They looked the same and liked many of the same things, yet their personalities were very different. What is responsible for these differences? Is it simply that they are two different people with different interests and preferences? Or did the environments that they grew up in play a part in making who they are? In the nature vs. nurture controversy, nature proclaims that our genetic make-up plays the primary role in human development, while nurture declares that our environment dictates our development.
“The term “nature versus nurture” is used to refer to a long-running scientific debate. The source of debate is the question of which has a greater influence on development: someone's innate characteristics provided by genetics, or someone's environment. In fact, the nature versus nurture debate has been largely termed obsolete by many researchers, because both innate characteristics and environment play a huge role in development, and they often intersect”. (Smith, 2010 p. 1)
The nature vs. nurture debate: the nature side, are those such as biologists, psychologists and others in the natural sciences, argue that behavioral traits can be explained by genetics. Those taking the nurture side are sociologists and others in the social sciences, they argue that human behavior is learned and shaped through social interaction. This argument should be dismissed because you don’t have to look far to see that both genetics and our environment, plays a role in who we are and our behaviors. (Glass). The point is there is a complex relationship between nature and nurture, either one alone is insufficient to explain what makes us human. (Colt). Our heredity gives us a basic potential,...
The proponents of the nature side of the nature vs. nurture argument hold the position that we are who we are because of our genetic code. They think that they have isolated genes that determine whether someone is predisposed to alcoholism, smoking, and mental as well as physical illness. In April of 2006, Susan Bergeson and a team of scientists at the University of Texas “found 20 gene candidates that could influence excessive drinking.” (Bryner. 2006) There have also been reports of a gene isolated that even determines the number of cigarettes that a person smokes based on how they metabolize the nicotine. There are those scientists who believe that we act on instinct alone based solely on our genetic makeup. This is a rather dangerous view because it relieves us of the responsibility we must all have for our own actions. Using the reason that one can’t control one’s behavior, they were simply born with a predisposition toward violence could be used as an excuse to commit violent crimes. Although we certainly have some genetic predispositions toward things like hair and eye color, certain diseases, and so on, it is not our genetic code that determines our life path for us.
A common dispute that has left people speechless for years is the debate between nature and nurture. Are humans influenced by their environments or their genetic make-up? This theory has not gone unnoticed while many theorists attempt to sway the opinions of their audience. Nature is comprised of our genetic and biological components that make us who we are while nurture is founded on the principle that humans are influenced by experience. I believe nature and nurture fall on a spectrum. Within the spectrum environmental, cultural, and genetic influences comprise a person’s unique
In a study conducted in 1983, researchers studied more than 350 pairs of twins in order to research if human personality traits were largely inherited or learned. Daniel Goleman, author of “Major Personality Study Finds that Traits are Mostly Inherited,” shares with his audience the parameters and results of this elaborate twin study. Goleman introduces his reader to Auke Tellegen, a psychologist and principal researcher on the long-term study, performed at the University of Minnesota, discovered that the human traits most strongly determined by heredity were leadership, obedience to authority, and even traditionalism. He would surely argue that heredity, more than influence of experience, is more responsible for development in human traits. Tellegen may have substantiating facts that nature is more predominant in a mere handful of traits, but what about the several other traits he failed to test? It is possible for a person who shows leadership and obedience during one part of their life to have an experience in which their obedience and leadership is thwarted. The study Tellegen conducted could not have been without environmental influence. Every single one of the participants, whether a twin or not, had environmental experiences separate from the others. Since every person experiences and responds to environmental stimuli differently, how can several prior years of experience be measured in order to present an unbiased result in this study? Unquestionably, it is impossible. Just as this particular study failed to take into consideration a persons’ prior experiences, it also failed to consider the probability of future environmental factors that could affect the traits Tellegen focused on in his study. Although difficu...
Nature is often defined in this debate as genetic or hormone-based behaviours, while nurture is most commonly defined as environment and experience.” (("Nature vs. Nurture", 2014, p.1) Many controversial debates have surrounded this issue and many researchers are trying to find evidence to justify if twin and adoption studies have an effect on the nature vs. nurture debate. Twin and adoption studies have had a positive influence on the nature-nurture debate because research and evidence has identified different issues and quality information to help the nature-nurture debate evolve. This essay will outline these positive influences and will elaborate on the research and evidence that has helped the nature-nurture debate.
For this first analytical essay, I have decided to have a go at analyzing the Nature Vs. Nurture using my own viewpoint as a sibling. No doubt this is a topic that has been debated to mental death already, but I think it is something I will benefit from thinking about. Also, at the end of my main topic, I will quickly address a topic brushed on in the book.
The quote from the famous psychologist John B. Watson essentially sums up behaviourism. Behaviourism refers to the school of psychology founded by Watson, established on the fact that behaviours can be measured and observed (Watson, 1993). In behaviourism, there is a strong emphasis that the acquisition of learning, or permanent change in behaviour, is by external manifestation. Thus, any individual differences in behaviours observed was more likely due to experiences, and not by the working of genes. As the quote suggest, any individuals can be potentially trained to perform any tasks through the right conditioning. There are two major types of conditioning, classical and operant conditioning (Cacioppo & Freberg, 2012).
In 1874, Francis Galton said, “Nature is all that a man brings with him into the world; nurture is every influence that affects him after his birth”. The human body contains millions upon millions of cells and each of these cells contains hereditary information and DNA. However, there is no proof that the information carried in these genes predetermines the way in which we behave. I believe it is our life experiences and what we see and are told that shape the way in which we behave. Therefore, it appears to me that nurturing plays a far more governing and dominant role in a human being’s development rather than nature.
The nature versus nurture debate is an old issue within the field of psychology. “The nature-nurture issue is a perennial one that has resurfaced in current psychiatry as a series of debates on the role that genes (DNA) and environments play in the etiology and pathophysiology of mental disorders” (Schaffner) The debate is essentially about what is inherited (nature) and what is experienced by environmental factors (nurture) and how they affect human development. Naturally, the nature versus nurture debate relates to many controversies such as intelligence, gender identities, violent behaviors, and sexual orientation. There are countless studies on whether intelligence is an inherited trait or if it is influenced by environmental factors.
Nature vs nurture debate is one of the oldest arguments in the history of psychology. It is the scientific cultural, and philosophical debate about whether human culture, behavior, and personality are caused primarily by nature or nurture. Nature and nurture are both equally important. They are the two are major influences that affect the person you grow to be and will determine what your children will be tomorrow. Nature refers to heredity, which are traits and features that are inherited from your parents and ancestors. At birth you, as a person, inherits 50% of each parent 's genetic material that are passed along through the chromosomes found in the DNA. Hair color, height, body type, and eye color are some examples of characteristics
