Note:

^*Note: indicates that the parameter was fixed to 0. SES= socioeconomic status; b=unstandardized regression coefficient; SE= standard error. Model fit statistics χ² (5, N=564) = 6.751, p=0.240; RMSEA= 0.025 (90% CI=0.000, 0.067); CFI=.983; SRMR=0.028. Sex was included as a covariate to account for potential sex differences in executive function, b_{sex, set-shifting} = −1.844, SE_{b-sex, set-shifting} = .642, b_{sex, inhibitory control} = 0*, SE_{b-inhibitory control} = N/A.
