The neural mechanisms of identifiable victim effect in prosocial decision-making

The data collection and preprocessing procedures were identical for both tasks. MRI data were acquired using a Siemens Prisma 3.0 T MRI machine at the Imaging Center for Brain Research at Shenzhen University. Functional volumes were acquired using multiple slice T2-weighted echo planar imaging sequences with the following parameters: repetition time = 1500 ms, echo time = 30 ms, flip angle = 75°, field of view = 192 × 192 mm2, 72 slices covering the entire brain, slice thickness = 2 mm, and voxel size = 2 × 2 × 2 mm3.
