G factor (psychometrics) (original) (raw)
- Der Allgemeine Faktor der Intelligenz (auch Generalfaktor der Intelligenz oder g-Faktor der Intelligenz) beruht auf der statistischen Beobachtung, dass in vielen Intelligenzleistungen mehr oder weniger stark ein allgemeiner Intelligenzfaktor mitwirkt. Dies rechtfertigt es, vereinfachend von „der“ Intelligenz zu sprechen. Mit keinem anderen psychologischen Konstrukt kann die Berufsleistung so genau vorhergesagt werden wie mit dem g-Faktor. Allerdings stellt er nur einen groben Orientierungswert für das Intelligenzprofil einer Person dar. Bei differenzierterer Betrachtung, wie es z. B. die Berufsberatung oder Neuropsychologie erfordern, ist es oft sinnvoll, die Ausprägungen spezifischer Intelligenzfaktoren zu unterscheiden. Die Vorstellung von einer allgemeinen geistigen Fähigkeit, die sich in einem einzigen Intelligenzwert ausdrücken lässt, war seit Beginn der Intelligenzforschung umstritten. Das war schon in den Forschungen von Charles Spearman zur Zweifaktorentheorie der Intelligenz der Fall. (de)
- The g factor (also known as general intelligence, general mental ability or general intelligence factor) is a construct developed in psychometric investigations of cognitive abilities and human intelligence. It is a variable that summarizes positive correlations among different cognitive tasks, reflecting the fact that an individual's performance on one type of cognitive task tends to be comparable to that person's performance on other kinds of cognitive tasks. The g factor typically accounts for 40 to 50 percent of the between-individual performance differences on a given cognitive test, and composite scores ("IQ scores") based on many tests are frequently regarded as estimates of individuals' standing on the g factor. The terms IQ, general intelligence, general cognitive ability, general mental ability, and simply intelligence are often used interchangeably to refer to this common core shared by cognitive tests. However, the g factor itself is merely a mathematical construct indicating the level of observed correlation between cognitive tasks. The measured value of this construct depends on the cognitive tasks that are used, and little is known about the underlying causes of the observed correlations. The existence of the g factor was originally proposed by the English psychologist Charles Spearman in the early years of the 20th century. He observed that children's performance ratings, across seemingly unrelated school subjects, were positively correlated, and reasoned that these correlations reflected the influence of an underlying general mental ability that entered into performance on all kinds of mental tests. Spearman suggested that all mental performance could be conceptualized in terms of a single general ability factor, which he labeled g, and many narrow task-specific ability factors. Soon after Spearman proposed the existence of g, it was challenged by Godfrey Thomson, who presented evidence that such intercorrelations among test results could arise even if no g-factor existed. Today's factor models of intelligence typically represent cognitive abilities as a three-level hierarchy, where there are many narrow factors at the bottom of the hierarchy, a handful of broad, more general factors at the intermediate level, and at the apex a single factor, referred to as the g factor, which represents the variance common to all cognitive tasks. Traditionally, research on g has concentrated on psychometric investigations of test data, with a special emphasis on factor analytic approaches. However, empirical research on the nature of g has also drawn upon experimental cognitive psychology and mental chronometry, brain anatomy and physiology, quantitative and molecular genetics, and primate evolution. Some scientists consider g as a statistical regularity and uncontroversial, and a general cognitive factor appears in data collected from people in nearly every human culture. Yet, there is no consensus as to what causes the positive correlations between tests. Research in the field of behavioral genetics has shown that the construct of g is highly heritable in measured populations. It has a number of other biological correlates, including brain size. It is also a significant predictor of individual differences in many social outcomes, particularly in education and employment. The most widely accepted contemporary theories of intelligence incorporate the g factor. However, critics of g have contended that an emphasis on g is misplaced and entails a devaluation of other important abilities. Stephen J. Gould famously denounced the concept of g as supporting an unrealistic reified view of human intelligence. (en)
- El factor g (también conocido como factor general de inteligencia) es un constructo desarrollado en investigaciones psicométricas sobre las habilidades cognitivas y la inteligencia humana. Es una variable que condensa diversas correlaciones positivas entre distintas tareas cognitivas y que demuestra que dos individuos pueden compararse partiendo del cómo se desenvuelven en cualquier tipo de tarea cognitiva, incluso siendo esta distinta para cada uno. En los tests de inteligencia el factor g suele suponer entre el 40 y el 50% de las diferencias entre individuos, por lo que es habitual que las puntuaciones obtenidas en estos sean contempladas como estimaciones de un “estatus intelectual” de los individuos sustentado en el factor g. (es)
- Le facteur g (diminutif de « facteur général », general factor en anglais et également connu sous le nom d'intelligence générale, capacité mentale générale ou facteur d'intelligence générale), est un concept développé dans le cadre des recherches en psychométrie sur les habiletés cognitives. C’est une variable qui caractérise les corrélations positives que la recherche empirique a trouvées de façon constante entre les tests d’aptitudes mentales, quel que soit le contenu des tests. Le facteur g est corrélé généralement 40 à 50 pour cent de la variance dans les résultats qui en résulte du bilan d'un test avec pronostiques de statistiques[pas clair]. Les termes intelligence générale, habileté mentale générale, QI ou simplement intelligence sont souvent utilisés de façon interchangeable pour se référer au noyau commun partagé par les tests d'aptitudes cognitives. Le concept et l'interprétation du facteur g font l'objet de vives discussions dans les milieux scientifiques. Les réalités mathématique et physique du facteur g sont mises en cause par certains spécialistes en statistiques et psychométrie. (fr)
- Il fattore g (in inglese: g factor, abbreviazione di "general factor", fattore generale) è un costrutto teorico relativo allo studio dell'intelligenza umana consistente in una generale capacità di risolvere problemi, concreti o astratti, di varia natura. L'esistenza del fattore g fu proposta inizialmente nel 1904 dallo psicologo e statistico britannico Charles Spearman in un suo lavoro sull'analisi fattoriale in psicometria. Osservando che la matrice dei coefficienti di correlazione di una serie di test tende a disporsi secondo elementi proporzionali per righe e per colonne (ordine gerarchico), Spearman suggeriva che alla base della correlazione ci fosse un singolo fattore generale, che chiamò g, comune a tutti i test. Oltre a g, sarebbero poi presenti dei fattori specifici diversi per ciascun test. (it)

- Em 1904, Charles Spearman publicou os resultados de suas pesquisas em que construiu matrizes de correlações para verificar o quão semelhantes eram as habilidades medidas pelos diferentes itens que constituem um teste destinado a medir a inteligência. Ele constatou que muitas vezes há apenas um fator que responde por mais de 70% da variância de dezenas ou até centenas de itens diferentes. Num teste com 50 itens, há 50 fatores (um para cada item) sendo medidos, porém esses fatores estão presentes em diferentes proporções, e geralmente poucos fatores principais explicam quase a totalidade do que é medido pelo teste. O fator g é o fator principal, isto é, aquele que explica a maior parte da variância total dos itens. A partir deste fato, propôs sua teoria de que existe um fator geral g que explica mais de 50% (e em alguns casos mais de 70% ou até 80%) da totalidade da inteligência. É uma teoria amplamente respaldada por mais de 1500 experimentos realizados nos últimos 100 anos, sempre confirmando que um só fator explica uma fração muito grande da totalidade do que o teste propõe medir. Mais tarde, em 1938, Thurstone propôs que além do fator geral g, pode-se também medir o quanto outros fatores específicos (ou secundários) explicam da totalidade da inteligência. Foi um passo importante para o desenvolvimento da Análise Fatorial e Análise de Conglomerados, que atualmente é utilizada para muitas diferentes finalidades, inclusive para taxonomia de animais, vegetais e minerais, para localização de assassinos seriais, para mapeamentos de densidade de probabilidades de localização de minerais subterrâneos, para prognósticos no mercado de ações, etc. Trata-se, portanto, de teorias científicas e fartamente documentadas por experimentos reprodutíveis, ao contrário de outras teorias sobre a mente, como as de Goleman e Freud, que alguns consideram "esotéricas". Convém deixar claro que o fato de as teorias de Goleman e Freud não serem científicias (na acepção de Popper), não significa que estejam erradas nem que tenham menos valor. Significa apenas que não são passíveis de verificação e falseamento, que são os critérios propostos por Popper para classificar uma teoria como sendo científica ou não. A não-cientificidade é sinônimo de ausência de corroboração empírica, o que torna uma teoria "suspeita", mas não necessariamente "errada". Veja mais detalhes em "Metodologia Científica", em "Karl Popper", em "Placebo" e em "Imre Lakatos". (pt)
- Фактор загального інтелекту (англ. general factor, g factor) є поширеним, але суперечливим конструктом, який використовується в психології для виявлення спільного в різних тестах інтелекту. Словосполучення «теорія g» має справу з гіпотезою і одержаними з неї результатами про біологічну природу g, постійністю / піддатливість, доречністю його застосування в реальному житті й іншими дослідженнями. (uk)
- Den generella intelligensfaktorn (förkortad g) är ett begrepp som används inom psykologin (se även psykometri) 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 en modell där variationerna i poängresultat från intelligenstester kunde förklaras av två faktorer. Den första är den specifika faktorn för en individuell mental uppgift: de individuella förmågorna som gör en person mer skicklig på en viss kognitiv uppgift än en annan. Den andra är g, en generell faktor som styr prestationerna inom alla kognitiva uppgifter. Ansamlingen av data från kognitiv testning och förbättringar i analytiska tekniker har bevarat g-faktorns centrala roll, vilket har lett till det moderna begreppet av g. En hierarki av faktorer, med g på toppen och gruppfaktorer på stegvis lägre nivåer, anses vara den mest vitt accepterade modellen av kognitiv förmåga. Andra modeller har även föreslagits, och en signifikant dispyt behandlar g och dess alternativa modeller. (sv)
- Фактор общего интеллекта (англ. general factor, g factor) является распространённым, но противоречивым конструктом, используемым в психологии (см. также психометрию) для выявления общего в различных тестах интеллекта. Словосочетание «теория g» имеет дело с гипотезой и полученными из неё результатами о биологической природе g, постоянством/податливостью, уместностью его применения в реальной жизни и другими исследованиями.
