q3 i? Across three cultural groups, the distinct abilities processing speed model fit better than the unitary ability model and the bifactor model. → Papadopoulos 2018

q3 · i? · associational · r2

Structural equation modeling compared three nested theory-driven models (distinct abilities, unitary, bifactor) in 320 university students from Canada (n = 115), China (n = 110), and Cyprus (n = 95) assessed on a computerized D-N CAS adaptation. The distinct abilities model was "the most parsimonious" and produced the lowest AIC and ECVI among the configural models.

"Results of structural equation modeling showed that (a) the model representing processing speed as a collection of four cognitive processes rather than a unitary processing speed factor was the most parsimonious"
