Self-control involves the inhibition of dominant response tendencies. Most research on self-control has examined the inhibition of appetitive tendencies, and recent evidence suggests that stimulation to increase right frontal cortical activity helps to inhibit approach-motivated responses. The current experiment paired an approach-avoidance joystick task with transcranial DC stimulation to test the effects of brain stimulation on the inhibition of both approach and avoidance response tendencies. Anodal stimulation over the right/cathodal stimulation over the left dorsolateral prefrontal cortex (compared to the opposite pattern of stimulation or sham stimulation) caused participants to initiate motive-incongruent movements more quickly, thereby suggesting a shared neural mechanism for the self-control of both approach- and avoidance-motivated impulses.

自我控制涉及对主导反应倾向的抑制。大多数关于自我控制的研究都考察了对欲望倾向的抑制,最近的证据表明,增加右侧额叶皮质活动的刺激有助于抑制趋近动机反应。当前的实验将一个趋近-回避操纵杆任务与经颅直流电刺激相结合,以测试脑刺激对抑制趋近和回避反应倾向的影响。右侧阳极刺激/左侧背外侧前额叶皮质阴极刺激(与相反的刺激模式或假刺激相比)使参与者更快地发起动机不一致的动作,从而表明对趋近和回避动机冲动进行自我控制存在共同的神经机制。(《心理学文摘数据库记录》
