Almost everyone in any related field has an opinion as to which is truly more important‚ nature or nurture. The director of a group called the Minnesota Study of Twins Reared Apart‚ Thomas Bouchard‚ believes that 70 percent of a person’s personality is genetic and 30 percent is due to environment. The director of the Lewisville Twin Study‚ Adam Matheny‚ however‚ says it is 50-50. In my opinion‚ both nature and nurture are very important. Nature and nurture are both influential to language

may begin to show. Aggression is one of the things which researchers are debating about; is it due to nature or nurture? Twin studies are very useful in this area because monozygotic (MZ) twins‚ who share 100% of their DNA‚ will prove whether or not aggression (or any other behaviour for that matter) is due to the genes we inherit. If the aggressiveness between MZ twins is more similar‚ this is considered to be down to the role of genes; for example‚ Coccaro et al found that nearly 50% of the

development can be illustrated in the studies of twins. Flanagan (2002) explored the Minnesota study in which a set of twins was raised separately. In one case‚ a set of identical twins was raised apart‚ known as the Jim twins. They did not meet until they were almost forty and had many similarities even though they were raised apart. There was no real explanation for all their similarities except that nature must play a crucial role in development. "The Minnesota twin study concluded that on multiple measures

because of this particular question psychologists began to do intensive research. They did this by studying each of the two theories separately. One psychologist‚ Plato‚ campaigned nature while the other‚ Aristotle‚ campaigned nurture. The studies began with nature. Nature is defined as the heredity or biological make-up that influences the outcome of one’s behavior and/or personality. Nature can also be defined as an individual’s innate qualities. Some psychologists‚ like Plato‚ suggest

Are serial killers naturally‚ instinctive psychopaths or are they the result of a corrupt upbringing? Are you more at risk of becoming a smoker because of your genes or is it a result of the peers you socialize with? Now‚ these types of questions have instigated disputes among psychologists in determining who we are‚ whether it is a result of nature‚ such as heredity‚ or is it the outcome of the nurturing of one’s environment that shape our personality? In other words‚ were you born with a blank

to be an addict if your mother was doing drugs or drinking will pregnant. That is wrong. An individual raised with addicts have parents have the ability to make the choice to be different from their parents and to stay away from toxic substances. Studies show that addiction is 50-60% genetic. (Genetics of Addiction 2014). There are still another 40-50% of people that have just made poor decisions and ended up as addicts. Roughly 50% of addicts that have a family history of addiction are able to overcome

It will argue how nature and nurture co inside with one and other through genotype-environment correlation. Also throughout the essay references will be

take identical twins‚ and give one the best environment possible‚ and put the other one in closet for eighteen years the differences will be profound‚ and caused totally by environmental differences between the two children. At the extreme the proponents of the Nurture side of the controversy would have us believe that the differences in human behaviour are like the differences in the twin’s behaviour. Believers in the Nature side of the argument tell you that split-twin studies are wrought with

frequently cited example of a heritable trait that has been studied in twins and adoptions. Identical twins reared apart are far more similar in personality than randomly selected pairs of people. Likewise‚ identical twins are more similar than fraternal twins. Each observation suggests that personality is heritable to a certain extent. However‚ these same study designs allow for the examination of environment as well as genes. Adoption studies also directly measure the strength of shared family effects. Adopted
