Figure 2. Results – Attentional Tasks (y-axis is inverse performance z-scores, thus lower/more negative scores indicate better performance).

Across all four tasks (filter, impulsivity, flanker, and task switch) three main trends are present. 1) LMM individuals generally outperform HMM individuals on all tasks. 2) Overall participants perform the tasks better after breath counting than after web browsing. 3) The beneficial effect of breath counting is disproportionately large in HMM individuals as compared to LMM individuals. Error bars indicate 95% confidence intervals.
