Comparisons between demographic characteristics and MMI scores of participants involved in VBM analyses and functional connectivity analyses.
Figure 1.
VBM regression analyses revealed that MMI scores were significantly associated with gray matter density in the ACC (t(70) = 5.16, PFWE-corrected <0.05, Cluster size = 158 voxels x 1.53 = 533 mm3; peak MNI coordinate: x = 12, y = 41, z = 3).
Adjusted gray matter density in the peak voxel (Y-axis) was negatively correlated (r = −0.54, p<0.001) with MMI scores (X-axis).

Correlations between Media multitasking index scores and Big Five Inventory scores.
Figure 2.
Regression analyses revealed that connectivity between the ACC ROI and the Precuneus (intersection of blue lines) was negatively associated with MMI scores (Precuneus; t(40) = 5.22, PFWE-uncorrected<0.001, Cluster size = 159 mm3; Peak MNI coordinate: x = 10, y = −50, z = 18).
There was a negative relationship (r = −0.68, p<0.001) between adjusted Z-transformed ACC-Precuneus correlations (Y-axis) and MMI scores (X-axis).
