Ego-depletion increases selfish decision making, but may also increase self-conflict and regret about those decisions.

ABSTRACT

The effect of ego-depletion on self-control conflict identification is the subject of ongoing debate with only limited and indirect empirical assessment. The present research used behavioral and self-report measures to test if ego-depletion affects self-control conflict identification across two studies in an economic social dilemma game and a probe reaction task. In the social dilemma game, ego-depleted participants acted more selfishly, but also reported feeling more conflicted about their decisions and were more likely to go back and change choices they had made earlier in the game. These results replicated and extended earlier findings on ego-depletion and prosocial behavior. Study Two tested the effect of ego-depletion on self-control conflict identification using a probe recognition task designed to measure goal conflict accessibility, but found no significant effects of ego-depletion.
