a) whole brain results of the contrast negative vs. positive feedback in the test and replication samples combined (N = 55, p < 0.005, FDR cluster corrected). b) Mean parameter estimates for negative > positive feedback activation in the medial PFC cluster in the test and replication samples combined (N = 55, as displayed in Fig. 3A), as well as for the samples separately (center of mass (x,y,z): −1, 55, 31). Note that this graph is purely for visual representation and is not used for statistical inferences. Error bars indicate standard error of mean.
