Methods: Measuring depressive symptoms, using clas- sical experimental paradigm of self-depletion, we examined the differential effect of self-depletion on temptation resistance among depressed and normal populations. Results: Compared with non-depleted participants, the depleted participants were less likely to resist food temptation (F(1) = 5.60, P = 0.020); depressive symptoms and self-depletion have significant interactive effect on temptation resistance (F(1) = 4.88, P = 0.030). Compared with normal participants, depressed participants were less likely to resist food temptation under self-depleted condition (MDepressed = 16.58 ± 5.40, MNormal = 13.35 ± 4.76); however, there was no significant difference between normal and depressed participants under non-depleted condition (MDepressed = 12.00 ± 3.14, MNormal = 13.19 ± 4.50). The differential effects of self-depletion between normal and depressed population could be explained by the lowered inhibition threshold in depressed participants. Conclusion: Depres- sion could be viewed as a self-regulatory disorder; self-regul
