Much of the research however, was not conducted with the CHC theory.Catell, Horn, Caroll, McGrew, and Flanagan, have all indicated that most IQ tests (specifically the Wechsler tests) do not appear to measure what they purport to measure. For instance, on the Wechsler tests, the Verbal IQ (which is "supposed" to measure verbal skills) is actually measuring a skill called crystallized knowledge or Gc, a sum of your cultural, verbal and linguistic knowledge.
This makes sense.
However, the Performance IQ (which is "supposed" to measure non-verbal reasoning) does not measure visual-spatial reasoning or Gv solely; it also taps fluid reasoning, or Gf – the ability to apply reason to deal with novel situations. Taken in this light, it makes perfect sense when you say that within an AS individual, Gc is greater than Gf.
To focus on VP differences, is in essence, very 20th century. Intellectual ability is not a simple construct, but incredibly complex and different depending on the child’s developmental level.
