[What causes self-control failure in delayed-cost dilemma: the role of affective expectancy and regulatory resource]

Two studies were conducted to examine the effect of affects on self-control behavior in delayed cost dilemma. Results of Study 1 suggested that long term negative affects such as regret and self-disgust might have facilitating effects on motivation of self-control if they were anticipated before delayed-cost dilemma situations, but inhibiting effects on self-efficacy of control when experienced after dilemma situations. Study 2 examined the effect of affect priming on self-control in eating behavior, as well as an interaction effect of anticipated affect and regulatory resource on it. Results indicated that participants who had enough regulatory resource succeeded in self-control, i.e. they ate less, regardless of the type of affect priming, but those who did not have sufficient resource and were not primed with long-term negative affects failed to control their behavior. It was argued that regulatory resource explanation of self-control should be expanded to the theory including anticipated affects.
