This table shows all activity surviving cluster-level correction across the whole brain (p < 0.05, FWE corrected; threshold of p < 0.005 used to define the clusters) for contrasts involving the following: the second-level covariate for risk (PropRisk_all) on activity for accept > reject; and the second-level covariate for valence (ImpValence) on activity for gain > loss. The negative correlation with risk preference (PropRisk_all) indicates greater activity for accepting (approaching) the lottery with increasing risk aversion. For each cluster is shown the following: the three constituent peaks with the highest Z-scores; the number of voxels at p < 0.005 (uncorrected); and the p value of the cluster after FWE correction across the whole brain.
