q3 i? Under the Baddeley and Hitch specification, the visuospatial factor showed the strongest relation to the intelligence factors, though only the visuospatial-to-Gv path reached significance. → Gray Shelley 2016

q3 · i? · associational · r2

SEM with the Baddeley and Hitch working memory structure and the four KABC-II subtests in the same sample. "the visuospatial factor was most strongly related to the two intelligence factors," with only the visuospatial-Gv path significant.

"Similar results were found with the Baddeley and Hitch (1974) model; the visuospatial factor was most strongly related to the two intelligence factors, although the only significant path was between the visuospatial and Gv factors."

• Cowan's three-factor embedded processes model fit young children's working memory data slightly better than Baddeley and Hitch's three-factor model and decisively better than Baddeley's four-factor episodic buffer model — related
• The focus of attention factor was the only significant predictor of both fluid reasoning and visual processing intelligence when all three working memory factors were entered — related
