Confirmatory factor analysis model for working memory capacity (WMC), fluid intelligence (gF), attention control (AC), mind-wandering during the laboratory tasks (MW), and external distraction during the laboratory tasks (ED). Paths connecting latent variables (circles) to each other represent the correlations between the constructs and the numbers from the latent variables to the manifest variables (squares) represent the loadings of each task onto the latent variable. Solid paths are significant at the p < .05 level, whereas dashed paths are not significant. Ospan = operation span; Rspan = reading span; Symspan = symmetry span; Raven = Raven Advanced Progressive Matrices; LS = letter sets; Anti = antisaccade; Sartsd = standard deviation of response time on the Sustained Attention to Response task; Sartacc = accuracy on Sustained Attention to Response Task; PVT = psychomotor vigilance task; AntiMW = mind-wandering during antisaccade; SartMW = mind-wandering during SART; PVTMW = mind-wandering during psychomotor vigilance task; AntiED = external distraction during antisaccade; SartED = external distraction during SART; PVTED = external distraction during psychomotor vigilance task
