Crystallized intelligence (g c) includes learned procedures and knowledge. It reflects the effects of experience and acculturation. It reflects the effects of experience and acculturation. Horn notes that crystallized ability is a "precipitate out of experience," resulting from the prior application of fluid ability that has been combined with ...
Composition of IQ Gains. The Flynn effect is the substantial and long-sustained increase in both fluid and crystallized intelligence test scores that were measured in many parts of the world over the 20th century, named after researcher James Flynn (1934–2020).
The Cattell–Horn–Carroll theory is an integration of two previously established theoretical models of intelligence: the theory of fluid and crystallized intelligence (Gf-Gc) (Cattell, 1941; Horn 1965), and Carroll's three-stratum theory (1993), a hierarchical, three-stratum model of intelligence. Due to substantial similarities between the ...
As with Cattell, Horn rejected the existence of an even higher level factor of general intelligence ‘g’ asserted by Spearman (1927). In Horn (1988) he reported a full list of such broad level abilities: g c (crystallized) g f (fluid) g v (visual) g a (auditory) q f (quantitative) g s (processing speed) TSR (Long-term storage and retrieval)
Cattell theorized the existence of fluid and crystallized intelligence to explain human cognitive ability, [20] investigated changes in Gf and Gc over the lifespan, [21] and constructed the Culture Fair Intelligence Test to minimize the bias of written language and cultural background in intelligence testing.

It’s normal for your testosterone production to slowly decline as you age. Most men begin to produce less testosterone after age 30, with testosterone production dropping by about one percent ...
Spearman's work was expanded upon by Raymond B. Cattell, who broke g into two broad abilities: fluid intelligence (Gf) and crystallized intelligence (Gc). Cattell's student, John Horn, added additional broad abilities to Cattell's model of intelligence.
In its latest EV intelligence report, consumer research firm J.D. Power projects that a massive amount of EVs returning off leases in the US will provide a large supply of EVs for sale ...
