Which of the following statements describes the Flynn effect?ResponsesIntelligence quotient (IQ) scores in the United States were higher in 2003 than in 1993.Intelligence quotient (IQ) scores in the United States were higher in 2003 than in 1993.IQ scores in the United States were lower in 1999 than in 1989.IQ scores in the United States were lower in 1999 than in 1989.Children who attend Head Start programs show short-term gains in IQ scores.Children who attend Head Start programs show short-term gains in IQ scores.There is no statistically significant relationship between IQ scores and creativity.There is no statistically significant relationship between IQ scores and creativity.People may earn higher scores when they are told the test is a personality assessment rather than an intelligence test.

Some research suggests that first born children may have higher IQ scores than their later born siblings. Do first-born identical twins have higher IQ scores than their second-born sibling? Data from a 1998 study were analyzed to determine whether first-born identical twins have higher IQ scores than their second-born siblings. Ten pairs of adult identical twins were assessed and their Full Scale IQ scores were calculated.Source: M. J. Tramo, W. C. Lodtus, T. A. Stukel, R. L. Green, J. B. Weaver, and M. S. Gazzaniga. “Brain Size, Head Size, and Intelligence Quotient in Monozygotic Twins.” Neurology 50, 1246–52.The following hypotheses were tested:H0: μd = 0Ha: μd < 0The following is the (edited) output for the test:SampleNMeanStDevSE MeanFirst-born10112.914.74.65Second-born10108.711.33.57Difference104.113.44.2395% lower bound for mean difference: −4.36t-test of mean difference = 0 (vs. > 0): t-value = 0.97, p-value = 0.179Which of the following is an appropriate conclusion based on the output? The data provide sufficient evidence to reject H0and, thus, conclude that the mean Full Scale IQ score for first-born identical twins is higher than the mean Full Scale IQ score for second-born identical twins. The data do not provide sufficient evidence to reject H0. We therefore conclude that the mean Full Scale IQ score for first-born identical twins is higher than the mean Full Scale IQ score for second-born identical twins. The data provide sufficient evidence to reject H0. We therefore conclude the data do not provide evidence to conclude that the mean Full Scale IQ scores for first-born identical twins is higher than that of second-born identical twins. The data do not provide sufficient evidence to reject H0. In other words, based on the data we cannot conclude that the mean Full Scale IQ scores for first-born identical twins is higher than the mean Full Scale IQ score for second-born identical twins.

Which statement best captures your text's conclusion regarding the notion that intelligence tests are biased in favor of some groups, and against others?A.Test bias probably contributes substantially to group differences in IQ scores; however, the issue has largely escaped the attention of researchers.B.Cultural bias has been eliminated from contemporary intelligence tests.C.Researchers are no longer concerned with the issue of potential cultural bias in IQ tests.D.Researchers are concerned that intelligence tests may be culturally biased, because test bias may be the primary source of group differences in IQ scores.E.While researchers are still concerned that intelligence tests may be culturally biased, test bias is probably not the main contributor to group differences in IQ scores.

Which of the following is not true of the term IQ?Question 5Select one:a.Intelligence test scores of today are always based on the old formula of comparing a child’s mental age to their chronological ageb.Intelligence test scores of today are determined by comparing a person’s performance on the test with the performance of others in the same age groupc.Scores near 100 are average

Which of the following is one explanation for the ‘Flynn Effect’?Question 9Select one:a.Intelligence has been influenced by a range of environmental forces.b.Recent generations are becoming more intelligent in terms of cultural knowledge, vocabulary and arithmetic.c.We are unfamiliar with test items and scores on tests that have changed over time
