The ego-depletion effect refers to a temporary failure of self-control exertion after first performing an effortful task. This phenomenon has experienced a replication crisis in the past few years. In the present series of experiments, we tried to replicate the ego-depletion effect using a 30-min modified Stroop task tapping two executive functions (inhibitory control and cognitive flexibility) as the depleting task. In the first study, we compared the performance of a handgrip endurance task after this depleting task or after a classic control task (i.e., reading color words) and failed to replicate the ego-depletion effect. We showed that the control task induced boredom and subjective fatigue. In a second study, we looked for a better control task and compared the color-word reading task to another possible control task used in the literature (i.e., watching a documentary). Controlling for boredom, subjective fatigue, motivation and affective state, we found that the video task was not boring and did not induce fatigue, drop in motivation or negative affective state, whereas the color-word reading task did. In a third study, we used the video task as the control task and the modified effortful Stroop task used in the first study as the depleting task and succeeded in replicating the ego-depletion effect. This series of experiments illustrates that the choice of an appropriate control task is crucial to observe an ego-depletion effect and that boredom is costly. Consequently, it appears necessary to control for boredom in any future replication study aiming to observe an ego-depletion effect. 相似文献

The large body of research used to support ego‐depletion effects is currently faced with conceptual and replication issues, leading to doubt over the extent or even existence of the ego‐depletion effect. By using within‐person designs in a laboratory (Study 1; 187 participants) and an ambulatory assessment study (Study 2; 125 participants), we sought to clarify this ambiguity by investigating whether prominent situational variables (such as motivation and affect) or personality traits can help elucidate when ego depletion can be observed and when not. Although only marginal ego‐depletion effects were found in both studies, these effects varied considerably between individuals, indicating that some individuals experience self‐control decrements after initial self‐control exertion and others not. However, neither motivation nor affect nor personality traits such as trait self‐control could consistently explain this variability when models were applied that controlled for variance due to targets and the depletion manipulation (Study 1) or days (Study 2) as well as for multiple testing. We discuss how the operationalization and reliability of our key measures may explain these null effects and demonstrate that alternative metrics may be required to study the consequences of the consecutive exertion of self‐control. © 2019 European Association of Personality Psychology 相似文献

We investigated a potential outcome of ego depletion manipulations and an important factor behind cooperative failure: a lack of openness to others’ dissenting opinions. Across five studies in a variety of task settings, we examined the effect of depletion manipulations on openness to dissent and investigated two negative emotions as potential mediators of this process: fatigue and anger. The results demonstrated a negative effect of depletion manipulations on openness to dissent through increased anger rather than fatigue (Studies 1–5). In Studies 3 and 4, we also eliminated perceived trust towards a task counterpart as a significant mediator of the relationship between depletion manipulations and openness to dissent. These findings help clarify the nature of ego depletion manipulations and shed light on why individuals may fail to consider others’ dissenting opinions and, thus, fall short of achieving cooperation. 相似文献
