The first aim of the study was to examine whether observed attentional control at age 2 accounted for unique variation in higher-level cognitive abilities at age 3, specifically, receptive language, cognitive flexibility, and behavioral IC. To assess these direct paths, visual search accuracy at age 2 was modeled as a predictor of performance on the PPVT, DCCS, and Marker Delay tasks at age 3. Direct paths between 10-month frontal EEG coherence and all 3-year dependent variables were originally modeled, however, because they worsened model fit and did not change the structural paths they were removed.
