Descriptive statistics and correlations for all study variables are presented in Table 2. Left and right frontal EEG coherence composites were correlated at both time points. Observed attentional control at age 2 was positively correlated with all 3-year cognitive outcomes. All variables were normally distributed (see Table 1). A path analysis was conducted to examine the associations between resting frontal EEG coherence at 10-months (controlling for 5-month values), observed attentional control at age 2, and receptive language, cognitive flexibility, and behavioral IC at age 3. The complete path model including standardized estimates can be seen in Figure 2. Mplus (Version 7; Muthén & Muthén, 2012) was used to conduct the analyses and Full Information Maximum Likelihood (FIML) was used to handle missing data.
