目前的研究表明，自我控制依赖于葡萄糖作为一种有限的能量来源。自我控制的实验室测试（即，Stroop任务、思维抑制、情绪调节、注意力控制）和社会行为（即，帮助行为，应对死亡的想法，在种族间互动中抑制偏见）表明（a）自我控制行为降低了血糖水平，（B）初始自我控制任务后的低血糖水平预示着随后的自我控制任务表现不佳，和（c）初始自我控制行为损害了随后的自我控制任务的表现，但饮用葡萄糖饮料可以消除这些损伤。自我控制需要一定量的葡萄糖才能不受损害地运作。自我控制的一个单一行为会导致葡萄糖下降到最佳水平以下，从而损害随后的自我控制尝试。
The present work suggests that self-control relies on glucose as a limited energy source. Laboratory tests of self-control (i.e., the Stroop task, thought suppression, emotion regulation, attention control) and of social behaviors (i.e., helping behavior, coping with thoughts of death, stifling prejudice during an interracial interaction) showed that (a) acts of self-control reduced blood glucose levels, (b) low levels of blood glucose after an initial self-control task predicted poor performance on a subsequent self-control task, and (c) initial acts of self-control impaired performance on subsequent self-control tasks, but consuming a glucose drink eliminated these impairments. Self-control requires a certain amount of glucose to operate unimpaired. A single act of self-control causes glucose to drop below optimal levels, thereby impairing subsequent attempts at self-control.
