The IQ scores of adopted children tested four times between infancy and adolescence were compared to characteristics of both their adoptive parents and their biological parents.
There is also no way to be able to differentiate, which changes are due to changes in the personality states or which are due to changes in the environment. When they resemble their adoptive families more, we see the influence of environment. A child born into a poor home often shows an improvement in intelligence if adopted by a more intelligent and stimulating family and it has been found that Negro children born into backward rural families improve steadily if they move to the city.
Black do relatively better in rote memory tests and relatively poorer is visual test.
In general the review reported that the higher the proportions of genes two family members have in common the higher the average correlation between their IQ's.
Both nature and nurture are significant in forming a personality. The dubious history of the heredity environment controversy can be easily traced as far back as the start of the present century with at least some historical evidence placing the roots of this dispute in the time of John Locke.
Corsini provides us with a somewhat more simplistic definition of the term intelligence. Rutter also uses the example of petty crime to support the argument of nurture over nature, following on from his claim that a percentage of anti-social behaviour can be attained from environmental factors influenced by nurture.
McCrae and Costa In order to separate and define which personality traits in a person are caused by the environment in which a person is placed nurture and which are caused by heredity nature there must be an agreed definition and measure of personality. The Essays on nurture have also provided ample evidence to support the importance of environment influences in individual development.
The high IQ scores of the black and interracial children showed that genetic racial differences do not account for a moor portion of the IQ performance difference between racial groups.
Nurture looks at individuals learning through experiencing and applying themselves, which can be altered by changing the environment. It is to these studies we will now turn our attention. The two are mutually inclusive, since innate tendencies are capable of expression on in terms of environments, and environmental influences can only act together with the genetic bases of individuality.
He supports the idea that anti-social behaviour is acquired through a shared ratio of nurtured influence and genetic inheritance: The ability to adapt to new situations and to handle concepts, relationships and abstract symbols. About 50 percent of the difference in intelligence between persons in a group is believed to be genetically determined, with the remaining variation due to each person's experience.
Jone's study shows that there is a modest difference in the intelligence test scores of twins reared apart and the more divergent the environments, the greater the difference.
By suggesting that the group with the significantly higher anti-social behaviour qualities was the proband adoptee group, he is stating that the control group, despite being exposed to the same conditions of adoption, did not develop anti-social behaviours, while the proband group was significantly did.
At this point one or two somewhat consistent differences can also be mentioned about race. The only single way to do so is to get identical twins to compare their personalities to non-identical twins. It is very problematic to find one that can be questioned to find the effects of the environment and genetics on ones personalities.
Genes heavily influence other physical characteristics such as height, life expectancy, weight, etc. The example of antisocial behaviour. The study also found that black and interracial children reared in the culture of the tests and the schools perform as well as other adopted children in similar families.
Twin, Adoption, and Family Studies. The findings point to the importance of interactions between genetic and environmental factors in the development of antisocial personality. This solidifies the idea that both nature and nurture induced anti-social behaviours are influential factors in deciding the cause of what brings anti-social behaviour on, but, as shown in his previous quote, affect the probability that anti-social behaviour will occur, but do not bring it on directly: It is to these studies we will now turn our attention.
The main statement of naturalists is that personality is natural. At this point one or two somewhat consistent differences can also be mentioned about race. The study also found that black and interracial children reared in the culture of the tests and the schools perform as well as other adopted children in similar families.
Nature Nurture Nature Nurture: Nurture also claims that given the right environment any person can achieve any life goal and or ambition within their own physical limit capability.
Jense found that orphanage children gained in IQ from an average of 64 at an average age of nineteen months to 96 at six years of age as a result of being given social stimulation and placement in good homes at between two and three years of age. According to this large group of psychologists, personality is built by the evolutionary process, where humans inherit behavioural patterns from a set of genes, which means that genes are the one thing that controls the way they behave.
Vermon concludes that we may attribute 60 percent of the determination of IQ status to heredity, 30 percent to environment and 10 percent to the combined effects of the two. Jensen argues however that reported differences in average IQ between black and white children is due in part to systematic genetic difference.
Nurture also claims that given the right environment any person can achieve any life goal and or ambition within their own physical limit capability.
The high IQ scores of the black and interracial children showed that genetic racial differences do not account for a moor portion of the IQ performance difference between racial groups. Of all the words used in pressed day psychology, intelligence is one of the most difficult to define and is also one of the most controversial.
TWIN STUDIES The importance of twin studies is evident if we look at the studies objectively, if intelligence is basically hereditary, identical twins who have the same genetic legacy, should be concordant for that trait than are fraternal twins which are no more alike genetically than other siblings.
