A. Mediation models and results. *** p < .001, ** p < .01. B. Both change-point probability and relative uncertainty predict P3 amplitude. Change-point probability and relative uncertainty estimates are sorted into 20 bins according to z-scored single-trial P3 amplitude, pooled across participants. The lines show the linear fit to the unbinned single-trial data.
