• Factors
  • IQ scores have been shown to be associated with such factors as morbidity and mortality, parental social status, and, to a substantial degree, biological parental IQ. (wikipedia.org)
  • By the mid-1930s, many United States psychologists adopted the view that environmental and cultural factors played a dominant role in IQ test results, among them Carl Brigham who repudiated his own previous arguments, on the grounds that he realized that the tests were not a measure of innate intelligence. (wikipedia.org)
  • differences
  • Despite the fact that the analyses were adjusted for parent IQ, it is possible that the group differences in outcome reflected intrinsic differences between the families who chose device closure and those who chose surgical closure. (ahajournals.org)
  • The first test showing differences in IQ test results between different population groups in the US was the tests of United States Army recruits in World War I. In the 1920s groups of eugenics lobbyists argued that this demonstrated that African-Americans and certain immigrant groups were of inferior intellect to Anglo-Saxon whites due to innate biological differences, using this as an argument for policies of racial segregation. (wikipedia.org)
  • In 1994, the book The Bell Curve argued that social inequality in the United States could largely be explained as a result of IQ differences between races and individuals rather than being their cause, and rekindled the public and scholarly debate with renewed force. (wikipedia.org)
  • fraction
  • However, the population of asymptomatic infants was larger than that of infants with encephalopathy, and therefore the population attributable risk fraction for an IQ score that might be attributable to the need for resuscitation at birth was 3.4% (95% CI 0.5-6.3) for asymptomatic infants and 1.2% (0.2-2.2) for those who developed encephalopathy. (biomedsearch.com)
  • The resulting fraction is multiplied by 100 to obtain the IQ score. (wikipedia.org)
  • average
  • Cognitive deficits in the autosomal dominant disorder Neurofibromatosis type 1 (NF1) typically consist of a lower than average IQ, impaired visual-spatial learning, attention problems and impaired executive functioning. (clinicaltrials.gov)
  • However
  • However, parent IQ and maternal education tended to be higher in the families who chose device closure of the ASD for their child. (ahajournals.org)
  • ages
  • The PPVT-IV was developed from adult norms obtained on 828 persons ages 19 to 40 selected to be nationally representative of geographical regions and major occupational groups. (wikipedia.org)
