Relative magnitude of neurocognitive mediation effects estimated from latent (Model 1) and manifest (Model 2) variable models of SES-related variation in academic achievement. Each bar represents the total number of SDs that a reading or math score is expected to change given a 1 SD change in SES, due to the effects of SES on neurocognitive ability variables in the model. The portion of the indirect effect attributable to a given neurocognitive ability variable is indicated by bar color. SES = Socioeconomic status. WM = Working Memory.
