The indirect effect from 10-month left frontal EEG coherence to 3-year PPVT performance (unstandardized estimate = 7.87, 95% BC Bootstrap CI [1.46, 16.42]), DCCS performance significant (unstandardized estimate = .21, 95% BC Bootstrap CI [.05, .43]), and Marker Delay performance (unstandardized estimate = .40, 95% BC Bootstrap CI [.09, .92]) were all significant. These findings indicate that greater increase in coherence between left frontal sites between 5- and 10-months was associated with a larger receptive vocabulary, greater cognitive flexibility, and greater behavioral IC at age 3 through its influence on observed attentional control at age 2.
