Recommended: Influence of environment on human behaviour
Individuals who support nature as the dominant influence will oppose the argument. Naturists believe that genetics and biology determine a child’s predisposition relating to development, they also argue that environmental factors, nurture, have little impact. Twin studies have found a correlation between intelligence and genetics, since twins have identical genes, by measuring their intelligence quotient scientists could establish a connection. “According to the Minnesota twin studies, identical twins IQ scores have correlations as high as .86, 1.00 being a perfect score,” (Hull, Licht, & Ballantyne, 2014). Although this information is valid, it isn’t correct for it doesn’t capture the entire picture. Genetics may influence intelligence determining
our genotype, but our environment determines which genes are expressed through our phenotype (Sigelman & Rider, 2015). This is what naturists fail to acknowledge, even if identical twins have a predisposed equivalent IQ, their socioeconomic status ultimately controls how their intelligence is expressed. After the Minnesota twin’s studies were conducted, a new factor was introduced, environment. By separating the twins, one in a financially stable environment and the other in a socioeconomically deficient environment, the correlation between their intelligence significantly dropped to around .71 (Hull, Licht, & Ballantyne, 2014). Interestingly enough, the correlation is still higher than that of fraternal twins who were “reared” together which have a correlation of .60. Yet, the decrease still proves that environmental factors have a greater influence because they regulate which genes develop into fruition. Culture influences behavior rather than social relationships, is another popular counter argument. This statement is one-hundred percent true, but the type of culture that has argued in favor of having greater influence over social relationships is entirely different. Within society, there are two kinds of behavioral cultures that each human can relate to, individualism or collectivism. Since America is primarily an individualist’s culture, people view themselves responsible for their own actions, thoughts, and decisions which all dictate behavior (Hopper, 2015). All these statements are true; however, children operate differently from functional citizens requiring a figure of guidance to develop the behavior. What separates a child from an adult is the development that is required for a child to become an adult. For children to successfully develop, they must establish a secure attachment with their guardian, if they instead develop a resistance, avoidant, or disorganized attachment, their behavior will permanently be altered throughout their life span. To establish a secure attachment the guardian must be sensitive and responsive to the child, if the parent is inconsistent, unresponsive, or abusive, the child will develop a negative attachment. Children experience a sensitive period around eighteen months in which they easily imprint onto a caregiver. From that point forward, whoever the child imprints on will help shape his/her behavior. The more quality time a guardian spends with the child, the more likely the child will properly develop both social skills and behavior etiquette. Research done by the Foundations Counseling concluded that parents who adopt authoritative and secure parenting styles produce greater chances of avoiding behavioral disorders in their children (Greenwood, 2013). How is it that an individualist culture has greater influence on child development than social relationships? A more accurate statement would be that behavioral culture influences social relationships, so through social relationships culture influences behavior.
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.
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.
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...
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).
As a mother, I am shocked and dismayed by the general acceptance of the myth of genetic determinism. One's environment, including people one interacts with, has an undeniable influence on how one develops. Nonetheless, many scientists disregard the impact of environment on one's intelligence. I do not deny that one's biology is a crucial part of one's identity. Inheritance of physical traits is obvious. Children often look "just like" their father or mother, or another relative. One's genes determine eye and hair color, height and body build. I believe, however, that what makes us human is not something that can be found in...
interpreted as being caused by genetic or environmental differences among groups? A strong promoter of the belief that there is undoubtedly a racial difference in intelligence is Phillippe Rushton. As a professor of psychology, he argues that there is irrefutable scientific evidence of difference...
Nature vs Nurture is a very long living debate that has been on the minds of many who study motor development. This can be a very difficult topic to choose a side to argue for because both Nature and Nurture have very strong points which prove they influence the development of a person. Nature refers to the genetic makeup and genetic relations an individual has linked to their birth parents. Nature is strictly about the genetics and the way these genetics make up and influence the way a person develops, behaves and lives their life. Nature refers to heredity and the traits an individual will obtain from their parents that have been passed down from generation to generation. Nurture refers to the environment one lives in and the experiences
Intelligence is a function of how well the brain works, and it's well established that our brains are designed by genes so it's not entirely surprising that some deem this as proof that our genes play a part in deciding a person’s intelligence. However, this is not a widely accepted fact and many scholars would argue intelligence is indeed not fixed by ones genes but instead manipulated by other factors.
Does Hereditary Influence IQ Scores? Stephen Gould’s monograph, The Mismeasure of Man, examines and denounces the belief of biological determinism. In Chapter 5, titled “The Hereditarian Theory of IQ”, Gould addresses the idea that the average intelligence quotient (IQ) of an individual is strictly based on their hereditary. Gould condemns the belief of hereditarianism through reconstructing and finding inaccuracies in the experiments that leading scientists and researchers in the field, such as H. Goddard, L. Terman, and R. Yerkes, made while supporting the idea of biological determinism. Gould articulates how scientists, who allow their own personal prejudices and bias seep into their data, have inaccurately mismeasured man from the beginning
There are countless studies on whether intelligence is an inherited trait or if it is influenced by environmental factors. A study was conducted with adopted children and non-adopted children to see if a conclusion can be made based on the influence of hereditary and environmental intellectual variation (Leahy). The study was conducted with strict standards to make it valid. For example, the adopted children that were studied were young; they also were brought up in similar backgrounds as the control children. Parents’ occupation was also similar, as this would affect the results if the parents had varying occupations (Leahy). The results from this study showed that:
The ongoing debate on whether nature or nurture is responsible for intelligence seems to be a never-ending argument. There will probably be no definite answer to this argument any time soon, but answers such as Dr. Bigot's prove how intolerant of other opinions people can be. To say intelligence is entirely based on genetics, or one's environment, for that matter, is utterly extremist. An interaction of both nature and nurture is responsible for intelligence.
What is the main influence on a baby? Is it their genetics or their environment? Naturally, babies always become temperamental when they’re hungry, gassed, or in need of a diaper change. That’s all by nature. Thought nature wouldn’t work in this case. Nurture plays a bigger role than nature in temperament as well as fearfulness. Babies are not necessarily born fearful, fear usually occurs as they develope. The main factor of whether the fear and temperament carries on, is dependent if and how the child is nurtured. So however children are nurtured, is how they are developing as adolescents. so considering in this situation , yes fearful children do not change. For example , a nurturing environment makes them feel save than being less fearful.

The study of nature development refers to the inherited characteristics and tendencies, these are genetic, and these which are inherited help influence the development through childhood. Some inherited characteristics appear in virtually everyone, For instance, almost all children have the capacity to learn to walk, understand language, imitate others, use simple tools, and draw inferences about how other people view the world. The coding of genes in each cell determine the different traits which we have, more dominantly on the physical attributes like eye colour, hair colour, ear size, height, and other traits. However, it is still not known whether the more abstract attributes
