Pressing the rewarding button: The relationship between impulsivity, fatigue, and reward sensitivity

This study suggested that when depleted, people prone to instant gratification will work harder than their less impulsive counterparts to earn rewards. To examine the reliability of these findings, we then did a high-powered, direct replication of this study (n=782). In the replication, we found null results. This pre-registered, well-powered study suggests the findings of study one were a type I error. The findings of study 2 suggest no effect of self-regulatory attention on tasks related to earning points.
