内隐的社会情感偏见反映在接近积极和避免消极刺激的倾向已经在人类中被记录了范例，如接近-回避任务（AAT）。然而，先发制人的认知控制在多大程度上可以帮助下调这些行为倾向仍然知之甚少。在接受功能性磁共振成像（fMRI）时，24名健康参与者完成了AAT的提示版本，其中他们通过根据刺激帧的颜色将操纵杆拉向自己（接近）或将操纵杆推开（回避）来回应快乐或愤怒的面孔。在一些试验中，他们被提示反转帧颜色/操纵杆动作指令。在刺激开始之前，反向线索与视觉空间和运动规划网络的失活以及随后对刺激的反应减慢相关。在刺激阶段，反向线索与a）激活认知控制区，包括右额下回（IFG）和右顶下小叶（IPL）;和B）减少右中央前回激活时，必须推动（避免）一个快乐的脸。总的来说，这些结果表明，主动参与认知控制可以帮助微调行为和神经调节情绪不一致的行为条件。
Implicit social-affective biases—reflected in a propensity to approach positive and avoid negative stimuli—have been documented in humans with paradigms such as the Approach-Avoidance Task (AAT). However, the degree to which pre-emptively engaging cognitive control can help down-regulate those behavioral tendencies remains poorly understood. While undergoing functional magnetic resonance imaging (fMRI), 24 healthy participants completed a cued version of the AAT, in which they responded to pictures of happy or angry faces by pulling a joystick toward themselves (approach) or pushing the joystick away (avoidance) based on the color of the stimulus frame. On some trials, they were cued to reverse the frame color/joystick action instructions. Prior to stimulus onset, a reverse cue was associated with deactivation of a visuo-spatial and motor planning network and subsequent slowing down in response to stimuli. During the stimulus phase, a reverse cue was associated with a) activation of cognitive control areas, including the right inferior frontal gyrus (IFG) and right inferior parietal lobule (IPL); and b) reduced right precentral gyrus activation when having to push (avoid) a happy face. Overall, these results suggest that proactively engaging cognitive control can help fine-tune behavioral and neural adjustment to emotionally incongruent behavioral conditions.
