Did you know that Auditory Processing (Ga) has a way higher g-loading on the new Woodcock-Johnson IV Cognitive Battery? It has increased from a correlation of 0.69 to 0.77, just under Fluid Reasoning (Gf), with a correlation of 0.78. But get this, it is even higher than Comprehension-knowledge (Gc), which is only 0.74! Does that mean that the WJ-IV Comprehension-Knowledge subtests are worse measures of (Gc) than before? They had a correlation of 0.79 on the WJ-III. Hmmm. What's your thoughts on this? See the table below.
