The article by Muraven, Tice, and Baumeister explores the concept of self-control as a limited resource, suggesting that self-regulation follows an energy or strength model. They argue that engaging in self-regulation depletes this resource, leading to subsequent impairments in other self-regulatory tasks. The authors conducted four studies to test this hypothesis: 1. **Study 1**: Participants who regulated their emotional response to an upsetting movie showed decreased physical stamina in a handgrip endurance task compared to those who did not regulate their emotions. This suggests that regulatory depletion occurs when people try to alter their emotional states. 2. **Study 2**: Participants who suppressed forbidden thoughts on a white bear task quit working on unsolvable anagrams sooner than those who expressed their thoughts or had no special instructions. This indicates that regulatory capacity is depleted by the effortful act of thought suppression. 3. **Study 3**: Participants who suppressed thoughts on a white bear task were less able to control their amusement in response to a funny video, compared to those who did not suppress thoughts. This further supports the idea that regulatory capacity is depleted by the effortful act of thought suppression. 4. **Study 4**: Autobiographical narratives of successful and failed emotional control linked prior regulatory demands and fatigue to self-regulatory failure, providing additional evidence for the strength model of self-regulation. The authors conclude that the strength model fits the data better than other models of self-regulation, such as activation, priming, skill, or constant capacity models. They emphasize the importance of understanding how and why self-control fails, as regulatory failure has significant personal and societal implications.The article by Muraven, Tice, and Baumeister explores the concept of self-control as a limited resource, suggesting that self-regulation follows an energy or strength model.
