Results from a set of region-of-interest analyses. dlPFC regions-of-interest (ROI) were drawn from fMRI studies on self-control in multi-attribute choice and in ITC [8]–[10].

Using data from two previous studies [21], [22], we tested whether task-induced activity in these regions predicted a reduction in reward-receipt responses in ventral striatum, i.e. effort discounting [22], and such activity predicted subsequent task-avoidance behavior [21]. All tests yielded significant effects, based on one-tailed t-tests.
