Cross-Cultural Differences in Cognitive Performance and Spearman's Hypothesis: 'g' or 'c'?

Administered two intelligence batteries and a computer-assisted elementary cognitive test battery to 474 second-generation migrant and 747 majority-group students, aged 6 to 12 years, in the Netherlands. Findings suggest that performance differences between these groups are better predicted by a cultural complexity ("c") factor than by cognitive "g." (SLD)
