Research Paper (postgraduate) from the year 2017 in the subject Medicine - Human Genetics, grade: 1, Egerton University, language: English, abstract: In an attempt to determine the factors that influence intelligence in humans, psychologists have investigated the issue from two principal perspectives: nature and nurture. As a result, research studies on these aspects have confirmed that both nature and nurture influences the development of intelligence. According to Heffner, genetic factors have been identified as the influential forces of nature that shape intelligence, whereas environmental factors influence intelligence through exposure or rather nurture. In both schools of thought, it is apparent that tests for intelligence are aimed at determining the level of intelligence through the use of Intelligence Quotient (IQ) test. Similarities and differences in IQ among individuals explain the degree at which genetics and environment influences development of intelligence. Therefore, this research paper discusses nature-nurture basis of intelligence.

How we raise young children is one of today's most highly personalized and sharply politicized issues, in part because each of us can claim some level of "expertise." The debate has intensified as discoveries about our development-in the womb and in the first months and years-have reached the popular media. How can we use our burgeoning knowledge to assure the well-being of all young children, for their own sake as well as for the sake of our nation? Drawing from new findings, this book presents important conclusions about nature-versus-nurture, the impact of being born into a working family, the effect of politics on programs for children, the costs and benefits of intervention, and other issues. The committee issues a series of challenges to decision makers regarding the quality of child care, issues of racial and ethnic diversity, the integration of children's cognitive and emotional development, and more. Authoritative yet accessible, From Neurons to Neighborhoods presents the evidence about "brain wiring" and how kids learn to speak, think, and regulate their behavior. It examines the effect of the climate-family, child care, community-within which the child grows.

This book provides an analysis of the nature vs. nuture debate, arguing for an end to the 'either/or' nature of the discussions in favor of a recognition that environmental and genetic factors interact throughout life to form human traits.

This book discusses the nature - nurture debate as it relates to human intelligence.

In The Selfish Gene, Richard Dawkins crystallized the gene's eye view of evolution developed by W.D. Hamilton and others. The book provoked widespread and heated debate. Written in part as a response, The Extended Phenotype gave a deeper clarification of the central concept of the gene as the unit of selection; but it did much more besides. In it, Dawkins extended the gene's eye view to argue that the genes that sit within an organism have an influence that reaches out beyond the visible traits in that body - the phenotype - to the wider environment, which can include other individuals. So, for instance, the genes of the beaver drive it to gather twigs to produce the substantial physical structure of a dam; and the genes of the cuckoo chick produce effects that manipulate the behaviour of the host bird, making it nurture the intruder as one of its own. This notion of the extended phenotype has proved to be highly influential in the way we understand evolution and the natural world. It represents a key scientific contribution to evolutionary biology, and it continues to play an important role in research in the life sciences. The Extended Phenotype is a conceptually deep book that forms important reading for biologists and students. But Dawkins' clear exposition is accessible to all who are prepared to put in a little effort. Oxford Landmark Science books are 'must-read' classics of modern science writing which have crystallized big ideas, and shaped the way we think.

This book presents the results of a thirty-five-year research project involving 300 families, each of whom adopted at least one child at birth from a Texas home for unwed mothers during the period of 1962-1970. The book weaves together information about the birth parents of the adopted children; information about the adoptive parents; and information about the children in these families. Children adopted at birth have two sets of parents. Birth parents provide their adopted-away child with a genetic endowment, but do not participate in shaping the child's environment. Adoptive parents do not contribute genetically, but are otherwise in charge of directing the child's development. If adopted children grow up to resemble birth parents they have never seen, the clear inference is that hereditary factors have had an influence. Environmental factors are implicated whenever children resemble their adoptive parents, but not the birth parents. The Texas Adoption Project was designed to investigate the impact of genetic and environmental factors. This unique and innovative longitudinal study is written for specialists and the educated public. An introductory guide is provided for the non-specialist reader explaining the form and statistical content of the tables. Additional technical material for specialists is contained in appendices. This important contribution to the literature on adoption will also be of interest to those interested in the relative weight of genetics and environment in human development.

Neuroscience has made phenomenal advances over the past 50 years and the pace of discovery continues to accelerate. On June 25, 2008, the Institute of Medicine (IOM) Forum on Neuroscience and Nervous System Disorders hosted more than 70 of the leading neuroscientists in the world, for a workshop titled "From Molecules to Minds: Challenges for the 21st Century." The objective of the workshop was to explore a set of common goals or "Grand Challenges" posed by participants that could inspire and rally both the scientific community and the public to consider the possibilities for neuroscience in the 21st century. The progress of the past in combination with new tools and techniques, such as neuroimaging and molecular biology, has positioned neuroscience on the cusp of even greater transformational progress in our understanding of the brain and how its inner workings result in mental activity. This workshop summary highlights the important issues and challenges facing the field of neuroscience as presented to those in attendance at the workshop, as well as the subsequent discussion that resulted. As a result, three overarching Grand Challenges emerged: How does the brain work and produce mental activity? How does physical activity in the brain give rise to thought, emotion, and behavior? How does the interplay of biology and experience shape our brains and make us who we are today? How do we keep our brains healthy? How do we protect, restore, or enhance the functioning of our brains as we age?
