成功地追求目标需要不断地运用自我控制来抵制沿途出现的诱惑或干扰。实验室研究已经确定了在孤立的自我控制情况下所调用的大脑系统，而生态学研究已经将自我控制能力与目标结果联系起来。然而，没有研究确定在长期追求目标过程中日常自我控制的神经系统。本研究结合神经影像学和经验取样方法，对试图戒烟的吸烟者成功自我控制的大脑系统进行了研究。27名吸烟者在尝试戒烟前，在功能性磁共振成像过程中完成了一项“做/不做”任务，然后在尝试戒烟的3周内，每天8次使用经验取样报告日常自我控制情况。基线时反应抑制过程中右侧额下回、前辅助运动区和基底神经节感兴趣区域的激活增加，与烟瘾和随后吸烟之间的关联减弱有关。这些发现支持了神经认知任务作为日常反应抑制指标的生态效度。
Successful goal pursuit involves repeatedly engaging self-control against temptations or distractions that arise along the way. Laboratory studies have identified the brain systems recruited during isolated instances of self-control, and ecological studies have linked self-control capacity to goal outcomes. However, no study has identified the neural systems of everyday self-control during long-term goal pursuit. The present study integrated neuroimaging and experience-sampling methods to investigate the brain systems of successful self-control among smokers attempting to quit. A sample of 27 cigarette smokers completed a go/no-go task during functional magnetic resonance imaging before they attempted to quit smoking and then reported everyday self-control using experience sampling eight times daily for 3 weeks while they attempted to quit. Increased activation in right inferior frontal gyrus, pre-supplementary motor area, and basal ganglia regions of interest during response inhibition at baseline was associated with an attenuated association between cravings and subsequent smoking. These findings support the ecological validity of neurocognitive tasks as indices of everyday response inhibition.
