2. What are the similarities and differences between Spearman's two-factor theory of intelligence and the information processing view of intelligence (Carroll's Three-Stratum Theory)?

Spearman proposed a two factor theory of intelligence based on findings from factor analysis. He compared the intelligence measures across a diverse range of samples. He did this by organizing the measured data into matrices, Spearman then isolated the factors that were correlated with other factors in determining intelligence levels (Williams, Zimmerman, Zumbo, & Ross, 2003, cited in http://sitemaker.umich.edu/356.loh/charles_spearman). Consequently, Spearman found "that every single variable was linked to each other to some degree and that a single general intelligence factor could account for all variables". Furthermore, he also found that "any small ...
