This kind of factor analysis has led to the theory that underlying these disparate cognitive tasks is a single factor, termed the general intelligence factor (or g), that corresponds with the common-sense concept of intelligence. In the normal population, g and IQ …

This test was developed and its performance characteristics determined by ARUP Laboratories. It has not been cleared or approved by the US Food and Drug Administration. This test was performed in a CLIA certified laboratory and is intended for clinical purposes.

Who coined this term? How did it influence IQ testing? And, how do modern psychometricians look at the g-factor? Watch this video to fin Den generella intelligensfaktorn är ett begrepp som används inom psykologin för att kvantifiera vad som är utmärkande för resultaten från alla intelligenstester. Psykometrikern Charles Spearman upptäckte under tidigt 1900-tal att elevers betyg i till synes orelaterade skolämnen verkade korrelera med varandra, och föreslog att dessa korrelationer speglade inflytandet av en dominant faktor som han kallade för g, en förkortning för "generell" intelligens. Han utvecklade Hierin wordt aangegeven hoe je op elke test gescoord hebt. Daarnaast wordt vaak ook je G-factor aangegeven.

Results of factor analyses indicate a strong g-factor of differences between nations (variance explained by the first unrotated factor: 94–95%). Causes of the high correlations are seen in the similarities of tests within studies, in the similarities of the WHY g MATTERS 81 g MATTERS ON THE JOB The nature of intelligence-specifically, the general mental ability factor g de- rived from factor analyses of large sets of diverse mental tests-is discussed in detail later.

Not everybody agrees. Some claim that there are multiple intelligence factors, which are (more or less) independent. Se hela listan på psychology.wikia.org All of these sub-tests are positively correlated due to an underlying factor –called g–that accounts for 40-50% of the variation between IQ scores. This suggests that IQ tests measure a certain factor that every individual is endowed with, rather than just being a haphazard collection of questions that have nothing to do with each other. The statistical extraction of g is performed by a technique called factor analysis. Introduced at the turn of the century by British psychologist Charles Spearman, factor analysis determines the minimum number of underlying dimensions necessary to explain a pattern of correlations among measurements.
