of the SPE range. Then three new onset regressors containing all trials of each bin were created and estimated for each left-out subject. The parameter estimates of these onset regressors represent the average height of the BOLD response for all trials in each bin. The data plots in Figures 3 and 4 are the average (across all left-out subject in the cross-validation analyses) parameter estimates (betas) converted to percent signal change for these 3 regressors.
