Does age moderate the effect of IQ on the differentiation of cognitive abilities during childhood?

Mapping the Dimensions of General Intelligence: An Integrated Differential-Developmental Theory

“…That is, differentiation occurs with increasing ability regardless of age. Facon [2006] found that ability differentiation is age dependent, showing up in late childhood. Obviously, these findings align with the distinction between mental and chronological age, implying that differentiation of abilities occurs as a function of mental rather than chronological age.…”

How does the strength of the relationships between cognitive abilities evolve over the life span for low-IQ vs high-IQ adults?

“…and young adolescents of high and low intellectual functioning ages 7-9, 10-12 and 13-15 years, Facon (2006) showed that median correlations between intellectual scores did not change with age for high-IQ participants (.13, .15 and .14 for the three age groups), whereas an increase was observed for low-IQ participants (.15, .16 and .25, respectively). Thus, it seems that only at the end of childhood (13-15 years) does the phenomenon described by Spearman begin to appear.…”

“…The data from Facon (2006) indicate an age-related effect of IQ on the differentiation of cognitive abilities during childhood, a result which, of course, must be corroborated and explained. In addition, the analysis of this Age × IQ interaction might also be pursued beyond adolescence to include the whole life span in order to give a fuller picture of the evolution of the magnitude of correlations between cognitive abilities as a function of IQ-level.…”

A diferenciação cognitiva na infância: um estudo de perfis cognitivos aos 5, 7 e 9 anos

“…Essa relação inversa entre o QI e a magnitude da correlação dos testes tem encontrado suporte empírico em vários estudos (Carlstedt, 2001;Coyle & Rindermann, 2013;Jensen, 2003). Facon (2006) analisou a magnitude das correlações entre os resultados nos subtestes da Wechsler Intelligence Scale for Children, Third Edition (WISC-III) por referência à distribuição do nível de habilidade cognitiva (alto e baixo QI) de três grupos etários definidos (7-9 anos, 10-12 anos e 13-15 anos). Verificou que a magnitude dessas correlações é praticamente igual nos grupos de alto e baixo QI até a faixa etária dos 10-12 anos.…”

“…A partir daí, e como seria previsto pela SLODR, as correlações tornam-se mais fortes para os indivíduos com baixo QI. Num estudo anterior com crianças de 4 e 9 anos, Facon (2004) também não teria encontrado evidên-cias para a diferenciação cognitiva, tendo assumido que esse fenômeno emergia, apenas, em idades mais avançadas (Facon, 2006).…”
