The statistical approaches were the same as those used for the GLM analyses. In the 1st-level analysis, we added the six head movement parameters of the brain functional dataset as covariates. In the 2nd-level analysis, we took a mixed-effects analysis using a one-sample t-test on the single-participant beta images with gender and age as covariates. GRF approach was used to correct for multiple comparisons. The threshold level was set at p < 0.001 at the voxel level and p < 0.05 at the cluster-level.
