Fig. 5

This figure illustrates mean beta values across these conditions within key brain regions, using literature-based coordinates: the ACC [left (MNI: −4, 26, 34), right (MNI: 6, 24, 30)] (Chechko et al. 2012), insula [left (MNI: −38, −1, −2), right (MNI: 40, −1, −1)] (Nguyen et al. 2016), and the right MFG [MNI: 42, 36, 33] (Ho et al. 2012) region, with error bars representing the standard error of the mean. Black asterisks above the bars indicate significant differences within each brain region, while blue asterisks in the radar chart highlight significant interaction effects, as seen with mean beta values in left ACC (significant interaction effect of film color and editing; F1.6, 100.9 = 4.172, p = 0.027, η2p = 0.060, Greenhouse-Geisser correction). The MNI coordinate system refers to the Montreal Neurological Institute standard brain. (*p < 0.05, **p < 0.005, ***p < 0.001).
