string: As is the default in the generalized PPI toolbox, the PPI regressors were created in the following way for each participant: (1) the time series of the seed region was defined as the first eigenvariate of BOLD activity in all voxels within the seed region (adjusted for effects of interest); (2) the resulting time series was deconvolved with the canonical HRF using the deconvolution algorithm in SPM853; (3) the deconvolved time series was multiplied by the predicted, pre-convolved time series of each condition, which resulted in one ‚Äúneural‚Äù PPI for each regressor; and (4) each neural PPI was convolved with the canonical HRF.
