Figure 4: Full MIMIC model relating four frontal brain variables to fluid intelligence and multitasking.

From: Distinct aspects of frontal lobe structure mediate age-related differences in fluid intelligence and multitasking

Figure 4

Significant brain–behaviour parameters are shown in green solid lines. All parameter estimates shown are fully standardized. This model fits the data well, χ2=52.912, df=24, P=0.001, RMSEA=0.046 (0.029–0.063), CFI=0.979, SRMR=0.029, Satorra–Bentler scaling factor=1.028. C1–C4 refer to the four sub-scores on the Cattell test of fluid intelligence; TTM (total time misallocated) and #tasks (number of tasks attempted) are two indices of performance on Hotel test of multitasking. *P<0.05, ***P<0.001. These P-values are based on a z-test statistic derived from a Maximum Likelihood Structural Equation Model using robust standard errors and a Satorra–Bentler scaled test statistic. See ref. 6767 for further details.
