Fluid and crystallized intelligence are thus correlated with each other, and most IQ tests attempt to measure both varieties. For example, the Wechsler Adult Intelligence Scale (WAIS) measures fluid intelligence on the performance scale and crystallized intelligence on the verbal scale. Fluid and crystallized intelligence are discrete factors of general intelligence, or g. Although formally recognized by Cattell, the distinction was foreshadowed by Charles Spearman who originally developed the theory of g and made a similar observation regarding the difference between eductive and reproductive mental ability. Susanne M. Jaeggi, from the University of Michigan, found that healthy young adults, who practiced a demanding working memory task (dual n-back) approximately 25 minutes per day for between 8 and 19 days, had statistically significant increases in their scores on a matrix test of fluid intelligence taken before and after the training than a control group who did not do any training at all. In the Analysis-Synthesis test, the individual has to learn and orally state the solutions to incomplete logic puzzles that mimic a miniature mathematics system. In the Matrix Reasoning test, children are presented a series or sequence of pictures with one picture missing. Im Gegensatz zum g-Faktor-Modell von Charles Spearman unterscheidet Cattell in seiner Zweikomponententheorie der Intelligenz 1971 zwei Faktoren zweiter Ordnung (Faktorenanalyse), die fluide und die kristallisierte Intelligenz. Oktober 2020 um 21:29 Uhr bearbeitet. There are various measures that assess fluid intelligence. It is necessary for all logical problem solving, especially scientific, mathematical and technical problem solving. His belief that Santa lives at the North Pole was then invalidated and new knowledge is gained: there is no Santa Claus. Cattell: Die empirische Forschung der Persönlichkeit, Weinheim 1973, S. 312, vgl. In psychology, fluid and crystallized intelligence (abbreviated Gf and Gc, respectively) are factors of general intelligence originally identified by Raymond Cattell. rule, concept, trend, class membership) that governs a set of materials. Other researchers have suggested that a lack of practice, along with age-related changes in the brain may contribute to the decline. The RPM is one of the most commonly used measures of fluid abilities. Sein Konzept schlug sich nieder in der Intelligenztest-Reihe Culture Fair Intelligence Tests. Since Matrix Reasoning and Picture Concepts involve the use of visual stimuli and do not require expressive language they are considered to be non-verbal tests of Gf. Working memory capacity is closely related to fluid intelligence, and has been proposed to account for individual differences in Gf. Propositional analogies and semantic decision tasks are also used to assess relational reasoning. “Improving fluid intelligence with training on working memory.” PNAS- Proceedings of the National Academy of Sciences], More recently, a study conducted in Hangzhou, China, at the University of Technology supports Jaeggi’s results, independently. For example, a child who has just learned to add numbers now owns a new piece of crystallized intelligence; but his or her general ability to learn and understand, Gf, has not been altered. Some researchers have linked the theory of fluid and crystallized intelligence to Piaget’s conception of operative intelligence and learning. R.B. In der Persönlichkeitstheorie entwickelte er mit Hilfe der Faktorenanalyse ein Modell von 16 bipolaren Dimensionen (als situationsunabhängige Grundeigenschaften der Persönlichkeit), mit der sich jede Person beschreiben ließe und die dem offen gezeigten Verhalten zugrunde lägen; sie schlagen sich im Fragebogen Sixteen Personality Factor Questionnaire (16 PF) nieder. This task assesses the ability to consider one or more relationships between mental representations or relational reasoning. It may be suggested that tests of intelligence may not be able to truly reflect levels of fluid intelligence. As the level of difficulty increases, individuals increasingly demonstrate an understanding of what constitutes a key difference (or the “rule”) for solving puzzles involving one to one comparisons, and on later items identifying common differences among a set of items. After student subjects were given a 10 day training regime, based on the dual-n back working memory theory, their scores on the Raven’s Standard Progressive Matrices, were found to have increased significantly. This is sometimes called investment. Fluid intelligence or fluid reasoning is the capacity to think logically and solve problems in novel situations, independent of acquired knowledge. If you continue to use this site we will assume that you are happy with it. Cattell entwickelte außerdem den Scree-Test zur Bestimmung der Faktorenzahl für die Faktorenanalyse. Why embracing pain, discomfort, or suffering, is a need for happiness? Improving fluid intelligence with training on working memory. Crystallized intelligence is the ability to use skills, knowledge, and experience. R.B. Concept Formation tasks assess inductive reasoning ability. Vocabulary tests and the verbal subscale of the Wechsler Adult Intelligence Scale are considered good measures of Gc. Raymond Bernard Cattell, nado en Hill Top o 20 de marzo de 1905 e finado en Honolulu o 2 de febreiro de 1998 foi un psicólogo británico-estadounidense, coñecido pola súa investigación psicométrica das estruturas psicolóxicas intrapersoais.
