Supplementary Figure 8: Neural other-conferred utility signal and preference-biased responses to direction of others’ choices are robust in the smallest subset of included participants.
From: Social signals of safety and risk confer utility and have asymmetric effects on observers' choices
To check the robustness of the results, we duplicated all analyses leaving out all participants who were excluded in any behavioral model fitting for OCU or Solo risk preferences (due to lacking a unique solution, leaving N = 49); each analysis showed comparable patterns and survived comparable statistical thresholds as for the larger sample reported in the main manuscript. (a, b) All neural findings reported the main text Fig. 3a and 3c were duplicated leaving out all participants who were excluded in any individual estimations or for scanning artifacts (leaving N=49 as the smallest subset of included participants). All displayed maps are displayed at P <.001 uncorrected, k > 10 contiguous voxels; the vmPFC and dACC clusters are significant at P < 0.02 FWE, SVC; the insula cluster is significant at P < 0.02 FWE.
