The second in the CHC Theory 101 series. This brief module traces, in broad strokes, the history of psychometric theories of intelligence from Spearman's g to contemporary Cattell-Horn-Cattell (CHC) theory
30. Contemporary psychometric research has
converged on the Cattell-Horn-Carroll (CHC) model
of cognitive abilities as the consensus working
taxonomy of human intelligence
