Changes in primary outcome metrics: Neural markers of attention.
a Time course of midline frontal theta (MFT) pre- and post-intervention at each 40 ms time bin during the perceptual discrimination task, where 0 ms represents stimulus onset. Solid lines represent the mean and shaded areas represent 95% bootstrapped confidence intervals (1000 bootstrap iterations). b Intervention-related improvements in MFT at early, peak, and late 120 ms composite windows, also illustrated through topographic heat maps with the 6 electrodes of interest highlighted with a dotted bounding box. Data are presented as mean ± 95% bootstrapped confidence intervals (1000 bootstrap iterations), and circles represent individual participants. P-values represent repeated-measures ANOVAs comparing pre- and post-intervention MFT at each composite window.

Changes in exploratory outcome metrics: Behavioral and parent-report measures of attention.
Intervention-related changes in objective behavioral and parent-report measures of attention, specifically a response time (RT) on the perceptual discrimination task, b tau on the sustained attention task, and c points on the Vanderbilt inattention subscale (parent-report). Data are presented as mean ± 95% bootstrapped confidence intervals (1000 bootstrap iterations), and circles represent individual participants. d Pearson correlations between midline frontal theta (MFT) improvements at each composite window and the behavioral and parent-report improvements.
