nature versus nurture
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. This controversy has continued despite continual reiteration that the critical question is not how much of a trait is due to heredity and how much is due to environment, but rather how environment transact to influence development. This paper will focus on the nature/nurture controversy and the extent to which an individual's intellectual level is determined either by inborn intelligence or by environmental factors. Psychologists and biologists striving to determine how heredity and environment influence the development of intelligence have actively pursed the relative powers of nature and nurture. Before we can go on to discuss the relationships between intelligence and the controversy that exists between the different schools of thought r!egarding inherited or environmental issues we must have an understanding of what intelligence really is. 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
Among 500 pairs of twins, identical twins became more and more alike in IQ from infancy to adolescence, while fraternal twins became less alike. It found, also, that siblings living indifferent foster homes resembled one another much less than brothers and sisters ordinarily do. IQ of identical twins are more highly correlated than less closely related people and IQ's of children growing up in similar circumstances tend to be more highly correlated than those of children growing up in dissimilar circumstances. For other special groups Jews tend to score higher than other white ethnic groups. The Minnesota Adoption Studies of 1974 included the Transracial Adoption Study to test he hypotheses that black and interracial children that are reared by white parents would perform on IQ tests and school achievement measures as well as other adopted children. Among these elements are some of the most relevant issues pertaining to this subject including: twin, adoption, family, orphanage life, IQ, and race studies. From the studies wehave gained an understanding of the importance of genetic constitution, the significance of which in the formation of intelligence and individuality is clearly demonstrated. These children generally show slower intellectual developments, as reported by Skeels and J. The Louisville Twin Study showed that environmental considerations such as characteristics of home and the interaction of the mother with the infant have a prominent effect upon the infant's mental development. ------------------------------------------------------------------------**Bibliography**. In order to investigate the topic of nature/nurture it is important to consider a variety of research elements. Clearly, the studies demonstrate that the contribution of nature and nurture may no longer be set in opposition for each is conceivable as one factor, or as a set of factors in a complex situation. The studies have also provided ample evidence to support the importance of environment influences in individual development. Their studies indicated that home environment scores during the first two years of life were strongly related to fifty-four month IQ scores. They concluded that individual differences in IQ are substantially influenced by genetic differences among individuals and that family environmentalso has a significant impact.
