Intelligence as a Product of Heredity or Environment
Is intelligence a product of hereditary or is it a product of an individual's environment? The nature versus nurture debate regarding intelligence is one that has raged long and hard. Innumerable studies have been conducted on this issue and there is still no clear-cut answer. However, since I am forced to argue one point of view for this assignment, I must conclude that intelligence is something that is hereditary.
I believe that a person's intelligence is set the day they are conceived. Intelligence is defined by Slavin as, "general aptitude for learning often measured by the ability to deal with abstractions and to solve problems" (128). Every individual has their own unique, natural tendencies, abilities, talents, and rates of learning. I have seen in P.S. 41, how one child can read a paragraph once and completely understand and another

Fried explained that one of the ways to assess the contributions of heredity and environment to intelligence is to compare siblings, especially, identical twins who were raised together and apart. He explained that, if intelligence is determined by genetic inheritance, then the correlation between the IQ scores should be greatest when the siblings have the greatest amount of genetic overlap. However, if intelligence is determined by environment, then the correlation between IQ scores should be greatest when siblings share the same environment. Studies that he spoke about that were conducted on identical twins reared apart found an extremely high correlation of intelligence scores between the individuals. The correlation was practical the same for the twins reared apart as it was for the twins reared together. How could this be if they were reared apart and did go through he same experiences or grow up in the same environment? The high correlation is because intelligence is a product of heredity. This study is strong support for the nature side of
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,...
Today, realising that genes and environment cooperate and interact synergistically, traditional dichotomy of nature vs. nurture is commonly seen as a false dichotomy. Especially operant conditioning, i.e. the learning of the consequences of one's own behavior can lead to positive feedback loops between genetic predispositions and behavioral consequences that render the question as to cause and effect nonsensical. Positive feedback has the inherent tendency to exponentially amplify any initial small differences. For example, an at birth negligible difference between two brothers in a gene affecting IQ to a small percentage, may lead to one discovering a book the will spark his interest in reading, while the other never gets to see that book. One becomes an avid reader who loves intellectual challenges while the other never finds a real interest in books, but hangs out with his friends more often. Eventually, the reading brother may end up with highly different IQ scores in standardized tests, simply because the book loving brother has had more opportunities to train his brain. Had both brother received identical environmental input, their IQ scores would hardly differ.
The bioecological model of intelligence, introduced by Stephen Ceci, concentrates on the potential abilities, environmental influence and internal motivation. To perform well in an intelligent test a person must have the necessary abilities, be in a positive environment and be motivated (Comer et al.,
Isaacson and Dweck begin and would agree with a similar base that intelligence, to a `certain point, is innate upon those who society sees as intelligent. Isaacson proves his viewpoint by exploring the mind of Steve Jobs, someone that most would consider to be the pinnacle of intelligence, and stating that “His imaginative leaps were instinctive, unexpected, and at times magical. They were sparked by intuition, not analytic rigor” (Isaacson 3). By emphasizing
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...
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.
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...
The debate on nature versus nurture has existed for thousands of years. Ancient philosophers Plato and Aristotle formed the argument through conflicting beliefs on the basics of human knowledge. Plato felt wisdom was innate, that all people were born with knowledge, and their experiences only helped to remind them of what they once knew. Aristotle challenged this through his belief of obtaining information through experiences. He viewe...
The human intelligence. The definition of intelligence is the ability to acquire and apply knowledge and skills. Every human in the world has intelligences, however with different developed level. Intelligence is important because it play a role as the human basis of survival. If there is no intelligence, all the money, communication and technology in the world won’t help, it will be like a dead world. If we human live in this world without
Most researchers believe that we are born with a certain intelligence or potential intelligence. They also believe that the intelligence we are born with is difficult to change. Psychologists use short-answer tests to assess one’s intelligence (Gardner papers). It was believed that intelligence was a single inherited thing. Human beings start out initially as a blank slate and could be trained to learn anything, provided that it was presented in an appropriate way (Multiple Intelligences and Education). Currently an “increasing number of researchers believe the opposite. Gardner defined intelligence as: “the ability to create an effective product or offer a service that is valued in culture; a set ...
Intelligence by definition is “the ability to acquire and apply knowledge and skills” (Oxford Dictionary, 2014). However, many psychologists argue that there is no standard definition of ‘intelligence’, and there have been many different theories over time as psychologists try to find better ways to define this concept (Boundless 2013). While some believe in a single, general intelligence, others believe that intelligence involves multiple abilities and skills. Another largely debated concept is whether intelligence is genetically determined and fixed, or whether is it open to change, through learning and environmental influence. This is commonly known as the nature vs. nurture debate.
Undoubtedly, humans are unique and intricate creatures and their development is a complex process. It is this process that leads people to question, is a child’s development influenced by genetics or their environment? This long debate has been at the forefront of psychology for countless decades now and is better known as “Nature versus Nurture”. The continuous controversy over whether or not children develop their psychological attributes based on genetics (nature) or the way in which they have been raised (nurture) has occupied the minds of psychologists for years. Through thorough reading of experiments, studies, and discussions however, it is easy to be convinced that nurture does play a far more important in the development of a human than nature.
This is an essay about the different theories of intelligence; it will discuss which theory is best at determining intelligence in my opinion. The information provided will help describe the pros and cons of each of the theories being used to define intelligence, explain why is it important to assess children’s intelligence, and discuss the type of intelligence I possess. The different theories of intelligence are complex and understanding the elements of each can help an individual choose the one that they believe is the best for determining intelligence. Comparing the positive and the negative elements of each theory of intelligence will allow an individual to see both sides of the theory and the flaws that may be twisted
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.
The Oxford Dictionary defines intelligence as “the ability acquire and apply knowledge and skills.” Many people are born naturally intelligent, able to grasp and understand concepts easily, with little work. In children, it is easy to separate those born with higher intellectual ability from the rest, because they easily excel in learning. This skill is often lost by those born with it, and through a great deal of work others attain it. In order for an individual to have true intelligence into her adult years, she must foster what gifts she is given, and strive to better her self academically. Even as early as elementary school, many who are born with natural talent begin to fall behind intellectually. These students are often not
