Figure 1.
Paradigm: Choices were presented on a screen with the smaller, sooner reward always presented on the left side.
After the subsequent presentation of a fixation cross (inter-trial interval), participants received feedback about the choice that was made by the decision maker.
Figure 2.
Contrasts of today trials with delay trials in A) SELF, and B) OTHER.
Abbreviations: dACC: dorsal anterior cingulate cortex, MPFC: medial prefrontal cortex, PCC: posterior cingulate cortex, Pcu: precuneus, vStr: ventral striatum.
Figure 3.
Interaction contrast of receiver and temporal distance (SELF [today-delay] – OTHER [today-delay]).
Parameter estimates (including standard error) are displayed for illustration of the interaction effects only.
Abbreviations: MOFC: medial orbitofrontal cortex; MPFC: medial prefrontal cortex; pACC: pregenual anterior cingulate cortex; vPCC: ventral posterior cingulate cortex; vStr: ventral striatum.
Figure 4.
Response-dependent contrasts of the feedback phase.
We contrasted A) the choice of the sooner option in today trials with the choice of the sooner option in delay trials, B) the choice of the sooner reward in today trials with the choice of the later reward in today trials, and C) the choice of the later reward in today trials with the choice of the later reward in delay trials.
