The Bell Curve is a book originally published in 1994. It was written by Richard Herrnstein and Charles Murray to explain the variations of intelligence in American Society. They accomplished this by using statistical analysis, for the purpose of raising warnings regarding the consequences of the intelligence gap. This was also made to propose a national social policy with the goal of mitigating bad consequences that have been attributed to this intelligence gap. Much of the information is widely considered controversial. An example of this is the low African-American scores compared to whites and Asians, and genetic factors in intelligence abilities. The introduction of the book starts with a brief history of intelligence theory and recent developments in intelligence thought and testing. The author creates six assumptions that has to do with the validity of the “classical” cognitive testing techniques. The first part of the book or chapters …show more content…
It talks about many different topics this affects. For poverty, it concludes to say that people that have a low IQ most likely live in poverty as it is a strong indicator. It says that low IQ drastically increases the chance of dropping out of high school, and further decreases said person to ever achieve getting a college degree. Low IQ is also associated with people that are unemployed, injured often, or “idle” to which they describe to mean removed themselves from the workforce. It also describes that families with lower IQ have high rates of divorce, lower marriage rates, and higher illegitimate births. Plus the familes children correlates with having low birth weight babies, poor motor skills plus social development, and possible behavior problems. Another one it includes is low IQ correlates with welfare dependency, increased criminal behavior, and people with low IQ are less likely to vote and care less about
The study required that participants must be given IQ tests, and also that they be observed in a classroom setting while interventions were put in place. Thus the adminsitratiors were able to draw results both from IQ scores and actual classroom preformance.
Before answering the questions let find out what intelligence test is. It is a test consisting of a series of tasks requiring people to use various verbal and non verbal skills to measure the individual’s intellectual ability. Now that we know what an intelligence test is we can now answer the question better. Three important short comings of intelligence test that have nothing to do with intelligence are: having low motivation or high anxiety which can greatly influence the performance on the test, also IQ test may contain cultural biases in their language and or tasks that may place people of one background above people of another back ground, and members of minority groups may have little experience with this kind of test or may be uncomfortable with examiners of a different ethnic back ground than them (Comer, 2013, pp.107).
In his article, “None of the Above: What IQ Doesn’t Tell You about Race” journalist Malcolm Gladwell refutes the notion that intelligence is based on genetics and argues that IQ is not just based on an individual’s level of thinking but also on the location where an individual resides. In 1984, James Flynn discovered that over the years, the IQ of people around the world had been increasing by three points per decade. This is now known as the Flynn effect. The IQ fundamentalists around the world believe that IQ score shows an individual’s level of thinking and it is based on genetics. However, Flynn effect disproves this
General intelligence tends to relate to various degrees with each other (Cohen 2012). An example of this is that if an individual is good in math, they may also be good in spelling. In this weeks reading we reviewed several different models of measurement of intelligence. In regard to these theories and general intelligence (g), the theories are various but have commonality and overlap. The Spearman's two-factor theory is if a test has high correlation with other test than the measurement of g is highly saturated (Cohen, 2012). The greater the importance of g on a test, the better the test is believed to predict intelligence
Intelligence tests have been developed by scientists as a tool to categorize army recruits or analyze school children. But still discussing what intelligence is, academics have a difficult time defining what intelligence tests should measure. According to the American researcher Thorndike, intelligence is only that what intelligence tests claim it is (Comer, Gould, & Furnham, 2013). Thus, depending on what is being researched in the test and depending on the scientist’s definition of intelligence the meaning of the word intelligence may vary a lot. This essay will discuss what intelligence is in order to be able to understand the intelligence theories and aims of intelligence tests.
Many psychology theories have been developed in order to determine how to measure intelligence. Volume 63 of the Annual Review of Psychology details a few studies citing popular theories from the 1970s to 2000 (Deary, 2012), including the measurement of, “sensory discrimination and reaction time,” (Deary, 2012). After 2000, however, “interest has focused, in the broadly psychometric-experimental levels, on processing speed and working memory as potential explanatory variables for intelligence,” (Deary, 2012). In measuring intelligence, scientists are focu...
The demographic used for the study is described as “highly advantaged children (middle-class whites with IQs of at least 135)…” (Gallagher). An IQ of 135 or higher is a very selective group and less than 1% of the entire world fits that criteria (“What Goes Into the Making of a Genius?”). With an IQ at or over 135, these children are more susceptible to anxiety, stress, and relationship issues among peers (“Social and Emotional Issues”). These troubles could directly impact their happiness and have a large effect on their lives if the issues persist. The results are even more limiting when the other factors such as race and financial background are taken into account. The lives led by these children are by no means typical and having access to certain advantages and a greater susceptibility to certain conditions can have an impact on the results. When 99% of the world is exempt from this study and the results are being applied to such a broad spectrum, it is not an acceptable application of the provided

Jensen’s talk is her assertion that IQ can actually be changed during adolescence because adolescent synaptic plasticity is just so much more responsive than in adults. The reality that reading ability can influence subsequent changes in verbal IQ is thrilling, because that means hard work actually can influence intelligence, instead of it being a static value. This fact actually reminds me of the “fixed mindset” versus the “growth mindset” idea; those who believe that intelligence can be changed actually do increase their intelligence, while those with the fixed mindset cannot improve. In addition, it gives hope to those with learning disabilities or those with Autism. With work and practice on specific skills, verbal IQ can improve and make life
In this world, there are many different individuals who are not only different in demographics but also different neurologically. Due to an immense amount of people it is important to first understand each individual, in order, to better understand them and to help them when it comes to certain areas such as education, the work force, and etc…. For this reason psychologists have aimed to further understand individuals through the use of psychological assessments. This paper aims to examine a particular assessment tool, the Stanford-Binet Intelligence Scales (Fifth Edition), which measures both intelligence and cognitive abilities (Roid, 2003). This assessment is usually administered by psychologists and the scores are most often used to determine placement in academics and services allotted to children and adolescents (despite their compatibility for adults) (Wilson & Gilmore, 2012). Furthermore before the investigation dives into the particulars of the test, such as its strengths and weakness’, it is best to first learn more about the intelligence scales general characteristics.
This is an essay about the different theories of intelligence; it will discuss which theory is best at determining intelligence in my opinion. The information provided will help describe the pros and cons of each of the theories being used to define intelligence, explain why is it important to assess children’s intelligence, and discuss the type of intelligence I possess. The different theories of intelligence are complex and understanding the elements of each can help an individual choose the one that they believe is the best for determining intelligence. Comparing the positive and the negative elements of each theory of intelligence will allow an individual to see both sides of the theory and the flaws that may be twisted
Recent information collected showing an increase to our IQs have many asking the question, are we smarting than our ancestors? Unlike our predecessors, we live in a time that poses a greater range of cognitive problems than our ancestors encountered, and as a result we've developed new cognitive skills and the kinds of brains that can deal with these problems. So in a way we are getting smarter throughout history, though it is widely debated if this is due to our environment or genes. Since IQ tests have been standardised many times over the last one hundred years, scientists have participants take a test designed for a previous age and record the results. What (Flynn, 1994) unearthed was that new test takers score much higher than those of the older generation. Flynn and his colleagues guessed that the difference in scores was due to improving modern environments. To them IQ is part heritable and part environmental- provide a child with opportunities to learn and they're likely to have a higher IQ later in

On the ‘nature’ side of the debate is the psychometric approach, considered to be the most dominant in the study of intelligence, which “inspired the most research and attracted the most attention” (Neisser et al. 1996, p. 77). It argues that there is one general (‘g’) factor which accounts for intelligence. In the 1880s, Francis Galton conducted many tests (measuring reaction times to cognitive tasks), (Boundless 2013), in order to scientifically measure intelligence. These tests were linked to the eugenic breeding programme, which aimed to eliminate biologically inferior people from society. Galton believed that as intelligence was inherited, social class or position were significant indicators of intelligence. If an individual was of high social standing, they would be more intelligent than those of a lower position. However he failed to show any consistency across the tests for this hypothesis, weakening his theory that social class correlated with intelligence. Nevertheless, his creation of the intelligence test led many to continue to develop...
