No longer able to or no longer wanting to? Are intention violations failures to exert or decisions not to exert self-control?

Several theoretical models describe two pathways linking self-control demands with subsequent goal violations. The volitional pathway suggests that these goal violations should be interpreted as failures, while the motivational pathway suggests an interpretation as decisions. In this article, we examined (a) which psychological processes may explain the relationship between self-control demands and subsequent intention violations and (b) to what extent these violations refect self-control failures rather than deliberate decisions. Results of two experience sampling studies showed that facing demands can trigger two opposing processes: fatigue, which leads to more subsequent violations of intentions, and the feeling that one deserves a reward, which leads to fewer subsequent violations of intentions due to boosts in self-efcacy. The actor may attribute intention violations to either an inability to act otherwise (indicating an actual failure) or a deliberate decision (indicating no failure). The diferent attributions have marked implications for the cognitive and afective downstream consequences of violating one’s goals, pointing to the importance of distinguishing between actual and apparent failures in self-control
