Nature Vs Nurture Environment Example For Students

Nature Vs Nurture : Environment Give me a dozen healthy infants, well-formed, and my own specified world to bring them up in and I ll guarantee to take any one at random and train him to become any type of specialist I might select – doctor, lawyer, artist, merchant-chief and, yes, even beggar-man and thief, regardless of his talents, penchants, tendencies, abilities, vocations, and race of his ancestors. – John B. Watson. Generally, using the terms nature and nurture as a suitable catch-phrase for the roles of genetics and environment in human and animal development dates way back to 13th century France. Some scientists feel that people act according to genetic inclinations or animal instincts. This is the nature theory of human behavior. Other scientists suggest that people reason and act in certain ways because they are taught to do so. This is the nurture theory of human behavior. The increasing understanding of the human genome has made it clear that both parties of the controversy have merit. Nature gives us inborn abilities and traits and it takes these genetic propensities and molds them as we learn and develop . The nature vs environment† argument is still on, as scientists debate over how much of who we are is shaped by genes and how much by the environment. Nature The human genome has been proven to determine the different traits that we have, majorly on the physical characters like eye color, hair color, ear size, height, and other traits. However, we are not certain about whether our abstruse characteristics like intelligence, personality, preferences, sexual orientation are gene-coded in our DNA, too. Also, the behavioral genes are somehow proven to exist when you observe fraternal twins. When fraternal twins grow up in different environments, they may respond and behave to certain situations as though they were reared together. Nurture The nurture theory insists thatalthough genes and heredity may influence abstract traits, environmental factors make the major contribution to human and animal behavior. This includes the use of conditioning in order to induce a new behavior to a child, or alter an unlikely behavior being shown by the child. John Watson, one of the leaders of the Nurture campaign, once said that he can be able to train a baby randomly chosen in a group of 12 infants, to become any type of specialist he wants. He stated that he could train him to be such regardless of the child s potentialities, talents and race. Even though fraternal twins raised apart often have remarkable similarities, still the differences in environmental influences may lead to several variations in the way they behave. We are still left in our dilemma: Are we born this way, or do we act in accordance to our life experiences? The nature vs environment controversy goes on and on, and although it is a fact that we have traits that are predetermined by our genes, we can still choose who we want to be as we travel through our lifetime. THE CONTROVERSY Over time, psychologists have tried to observe the relative amount contributed by genetics or environmental factors to diverse human behaviors. The frequently asked question is whether human and animal behavior is determined by the person’s genetic inheritance or is the behavior determined by upbringing . The concern in this question resulted to what is called the Nature Nurture Controversy. Many researchers took extreme positions in this issue, while some researchers exercised on exclusive roles or genetic hereditary, others took the opposite extreme by denying biological contribution and emphasizing learning and experience . John Locke . He posits that new born children are like ‘’tabular rasa’’ or ‘’blank slate’’ which is an example of a white board or black board, and anything written on this board can only be attributed to learning and experience. According to this view, nature contributes nothing to human behavior apart from providing a life body. Although this position was later disproved, the idea had enormous effect in philosophy, politics, and psychology. The opposite side of this debate holds that humans are born with complete genetic instructions that determine their response to every situation. One of the strongest argument in support of this position was Wilhelm Von Heibnits. His main argument on position is that we are the way we are born, which he based it on the belief that genes and hereditary must contribute to human behavior, this position is invalid because there is no particular or one gene responsible for behavior. Although genes act at a molecular level in the development and maintenance of the structures that has consequences of behavior, the inheritance of behavioral traits follow a multi-factorial pattern which involves actions of many genes and interactions between heredity and environment. In modern times, researchers have demonstrated that both hereditary and environment play a role in behavior through their interactions. Human behavior is therefore a result of the complex interactions between hereditary and environmental factors. Hinduism And Forgiveness EssayImprinting provides an opportunity to learn key variable components in an environment while retaining largely innate behavioral patterns. More flexibility may be shown in the development of food preferences, as food availability can vary from habitat to habitat, or from season to season. Insects may imprint on the chemistry of the leaves they eat as caterpillars; when they become adults they then choose to lay their eggs on plants with a chemistry that matches the leaves they ate when young. This insures a suitable diet for the next generation. Young birds and mammals often learn food preferences based on food shared by adults, on observations of feeding preferences of adults, and on sampling possible food items. Another form of learning involves aversions, which can develop at any point in any animal’s life. Birds and mammals develop lifelong aversions to specific foods that contain poisons that cause sickness (such as monarch butterflies). In contrast, some preferences and aversions appear to be innate, or at least to be driven by physiological needs for certain nutrients, such as salt. Genes and Environment in Human Behavior: Sociocultural Influences. Quite often humans worry that their behavior might be completely controlled by their genetic make up, meaning that one might be involuntarily compelled into poor parenting, violent behavior, or drug addiction. Most human cultures also has strong beliefs in self-determination and free will, as well as the ability of humans to be able to differenciate the right from the wrong and to make choices about the appropriateness of their actions. Heated arguments among biologists, philosophers, and ethicists over the relative roles of genes and behavior in human behavior have brought no simple resolution. The and will continue to fuel controversy, even as more is discovered about the genetic and evolutionary bases of behavior. TWIN STUDIES AND ADOPTION STUDIES One way to determine the contribution of genes and environment to a trait is to study twins. In one kind of study, identical twins reared apart are compared to randomly selected pairs of people. The twins share identical genes, but different family environments. In another kind of twin study, identical twins reared together (who share family environment and genes) are compared to fraternal twins reared together (who also share family environment but only share half their genes). Another condition that permits the disassociation of genes and environment is adoption. In one kind of adoption study, biological siblings reared together (who share the same family environment and half their genes) are compared to adoptive siblings (who share their family environment but none of their genes). The nature side of this debate emphasizes how much of an organism reflected are s biological factors. But, on the other hand genes are activated at appropriate times during development an the basis for protein production. Proteins include a wide range of molecules, such as hormones and enzymes that act in the body as signaling and structural molecules to direct development. CONCLUSION Although they may seem alternate and antagonistic in constitution, nature and nuture,work hand in hand in defining human and animal behavior. Many aspects of human behavior, which can not be explained by genetic and behavioural analysis of parents can be explained by evaluating the influences of the individuals social and physical environment.
