Based on Nisbett, experience and environments has a greater impact on people’s intelligence than biology. In some case, scientists have implied that the point difference in IQ is due to a genetic difference between races. However, research has demonstrated that the evidence profoundly favors the view that race differences in I.Q., the measure of intellectual functioning, are in fact environmental rather than genetic. According to Wade, Tavris, and Garry, they seem to also agree with Nisbett in that experience and environments has a greater impact on people’s intelligence. An example they gave was the tomato. Even though both seeds are genetically different from one another, the average differences between the two pots could be environmental.

Heritability means the proportion or percentage of perceives differences in a specific attribute that can be credited to genetic factors rather than environmental. This means heritability may not be the results of a biological study, but instead heritability estimates derives from a statistical analysis of a given population. An example of heritability is comparing people who are more closely biologically related vs. people who are less. You are going to share more of your genes with one of your siblings, 50%, rather than one of your cousins, 12.5%.

Some scientists have believed that I.Q. tests are “culturally biased”; they believe whites were born with a higher intellect than other people of different ethnicities. The authors of both articles, however, agree human intelligence is not base on genes, but rather the environmental factor. According to the research and evidence mention in the articles, the authors believe the genetics basis for the I.Q. differential is indirect. Meaning a tr...

...n of the children greatly influence on how healthy the environment is. The higher the I.Q. the children have the more successful and prosperous his/her environment is. In contrast, the lower the I.Q. the children have the more poverty and pollution the environment has. An example is mentioned in the article Our Human Diversity: The Case of Intelligence; country such as Kenya is experiencing a rapid growth due to an increase in intelligence. This allows improvement in education, healthcare, diets, and job opportunities.

Psychology is the scientific discipline concerned with the human mind and behavior. It uses the understanding of people, their thoughts, and their emotions to help solve human problems. In the case of Wade, Tavris, Garry, and Nisbett, I believe psychologist study intelligence to help improve people’s lives and the condition of their environment.

The Role of Genes in the Development of Behavior Essay

- The Role of Genes in the Development of Behavior The debate concerning the influence of genes on human behavior has been on-going for centuries. The nature vs. nurture (or heredity Vs. environment) debates are one of the longest running, and most controversial, both inside and outside psychology. It is concerned with some of the most fundamental questions a human being could ask, such as 'Why are we they way we are?' and 'why do we develop as we do?' Historically this debate has been fought from extreme perspectives, arguing that it is either nature (an individuals heredity genetic make up), or nurture (the environmental influences upon an individual) that determi...   [tags: human behaviour]

Essay on Nature vs. Nurture and the Impacts on Human Intelligence

- In current times many psychologists agree that nature (genes) and nurture (environment) both play important roles in the sculpting of intelligence in individuals, they work together constantly to guide maturity. This paper will look briefly at how intelligence is measured and the validity of those measurements. Additionally an argument for how environmental factors; education and parental health may influence the intelligence level of the individual throughout life. The Wechsler scales, among others are one of the most widely individually administered measures of cognitive function (Wechsler, 1997) and together with other psychometric assessments have proved useful for identifying students...   [tags: Intelect, Environment]

Essay on Similarities Between Human And Chimpanzees

- Through many centuries of passionate research and dedication on behalf of scientists worldwide, the general consensus among them is that human’s and ape’s are overwhelmingly similar. Years of research, comparison and evaluation have allowed for scientists and science enthusiasts to draw conclusions about not only the similarities between human’s and chimps, but how those similarities translate to similarities and differences between human’s and their behavior. Despite valid and accurate conclusions being drawn, Marks notes significant examples of scientists incorrectly using apes to draw conclusions between human behavior and differences overall, as seen in his noted examples regarding diffe...   [tags: Brain, Human, Scientific method, Chimpanzee]

Essay on Behavioral Genetic Determinism: Do Genes Equal Behavior?

- Behavioral Genetic Determinism: Do Genes Equal Behavior. Human behavior is a loosely defined foundation for individuality, generally considered to be influenced and developed by the environment. However, recent molecular studies have exposed genetic factors that suggest a more biological origin for behavior. Gene segments in the genome of humans and other animals have been identified and associated with particular behavioral traits. Is it possible that the presence or absence of even a single gene may predispose one to alcoholism, increased irritability, or enhanced intelligence....   [tags: Science Biology Biological Essays]
