Hierarchical Representation of the CHC-M Composite Model (Adapted From Webb et al., 2018). g = general intelligence; Gf = fluid intelligence; Gc = crystallized intelligence; Gv = visual processing; Glr = long-term storage and retrieval; Gsm = general short-term memory; Gs = processing speed; EF = executive functions; STM = short-term memory; LWM = low-working memory; HWM = high-working memory. EF features a dotted outline to indicate its absence in the original CHC framework and subsequent addition by Webb et al. (2018) to create CHC-M.
