Sex differences in human intelligence have long been a topic of debate among researchers and scholars. It is now recognized that there are no significant sex differences in average IQ, [1] [2] though particular subtypes of intelligence vary somewhat between sexes. [3] [4]
IQ Range ("deviation IQ") IQ Classification 145–160 Very gifted or highly advanced 130–144 Gifted or very advanced 120–129 Superior 110–119 High average 90–109 Average 80–89 Low average 70–79 Borderline impaired or delayed 55–69 Mildly impaired or delayed 40–54 Moderately impaired or delayed
IQ scores can differ to some degree for the same person on different IQ tests, so a person does not always belong to the same IQ score range each time the person is tested (IQ score table data and pupil pseudonyms adapted from description of KABC-II norming study cited in Kaufman 2009). [12] [13] Pupil KABC-II WISC-III WJ-III Asher: 90: 95: 111 ...
In psychology, human intelligence is commonly assessed by IQ scores that are determined by IQ tests. In general, higher IQ scores are associated with better outcomes in life. [ 11 ] However, while IQ test scores show a high degree of inter-test reliability , and predict certain forms of achievement effectively, their construct validity as a ...
Health can affect intelligence in various ways. Conversely, intelligence can affect health.Health effects on intelligence have been described as being among the most important factors in the origins of human group differences in IQ test scores and other measures of cognitive ability. [1]
An intelligence quotient (IQ) is a total score derived from a set of standardized tests or subtests designed to assess human intelligence. [1] Originally, IQ was a score obtained by dividing a person's mental age score, obtained by administering an intelligence test, by the person's chronological age, both expressed in terms of years and months.
Full Scale IQ (FSIQ), based on the total combined performance of the VCI, PRI, WMI, and PSI. The WAIS-IV can generate an FSIQ in the range of 40 to 160. General Ability Index (GAI), based only on the six subtests that the VCI and PRI comprise; it is intended to portray a snapshot of general intelligence that is less influenced by working memory ...
The resulting IQ standard score is the subject of much investigation as psychologists check correlations between IQ and other life outcomes. The Wechsler IQ tests for adults and for children have long been regarded as the "gold standard" in IQ testing. [1] fMRI data showing regions of activation
