2.6.4. Region of interest analysis

We selected the aMCC, mPFC, and NAcc as a priori regions of interest (ROIs) based on previous studies that linked responses in these regions to self‐reward and other‐reward (Apps & Ramnani, 2014; Enzi et al., 2009; Knutson et al., 2005; Lockwood et al., 2018; Moran et al., 2006). We built spheres with a radius of 5 mm centered at the coordinates of the vaMCC ([4, 24, 24] Enzi et al., 2009), daMCC ([−3, 19, 38] Moran et al., 2006), mPFC ([−3, 47, 0] Moran et al., 2006), and NAcc ([−11, 11, −4] and [12, 14, −4] Knutson et al., 2005) based on literature evidence using the MarsBaR 0.44 (Brett, Anton, Valabregue, & Poline, 2002). Greater neural activity in these regions was correlated with behavioral indices using bivariate correlations. The α value was set at 0.007 using Bonferroni correction (i.e., 0.05/7 ≈ 0.007) to correct for multiple comparisons (seven subscales).
