  1. MNI coordinates (x, y, z) and T value corresponds to the local maxima peak of the cluster activations at SVFWE corrected P < 0.005 (cluster labels are from AAL atlas88). Statistical maps were assessed for cluster-wise significance using a cluster-defining threshold of t(19) = 3.58, P = 0.001; and using small volume corrected threshold of P < 0.005 (referred to as a small volume family-wise-error (SVFWE) correction) within the frontal search volume.
  2. Description of contrasts: IntraAudSV > 0: contrast capturing responses elicited by changes in subjective value (SV) when choice options consisted of two auditory stimuli (AudAud). The contrast corresponds to the overall responses elicited by either low-pitch (lpSV) or high-pitch (hpSV) auditory stimuli. Thus, this contrast reflects the combined response to both types of auditory stimuli.
  3. IntraVisSV > 0: contrast capturing responses elicited by changes in subjective value (SV) when choice options consisted of two visual stimuli (VisVis). The contrast corresponds to the overall responses elicited by either green (gSV) or red (rSV) visual stimuli. Thus, this contrast reflects the combined response to both types of auditory stimuli.
  4. InterAudVisSV > 0: contrast capturing responses elicited by changes in subjective value (SV) when choice options consisted of one auditory and one visual stimulus (AudVis). The contrast corresponds to the overall responses elicited by either auditory (aSV) or visual (vSV) stimuli. Thus, this contrast reflects the combined response to both types of stimuli.
