个体表现出一种自然的倾向，倾向于接近积极的社会线索（例如，微笑的脸），并避免消极的线索，这可能在精神疾病中发生改变。计算机化的方法/回避训练促进情感一致的行为已被证明对调节这种偏见是有用的。在这里，我们研究了暴露于较高的一致性率如何影响社会情感线索的神经处理。在接受功能性磁共振成像（fMRI）的同时，24个人完成了两个版本的接近-避免任务（AAT），在这个任务中，他们必须接近或避免快乐或厌恶的动态面部表情。在高一致性条件下，一致性反应（即接近快乐的面孔，避免厌恶的面孔）更频繁。平衡条件下的一致反应和不一致反应数量相等。对社会线索的一致趋近-回避行为的加工与在一致性强化条件下相对于平衡条件下较低的右前脑岛招募有关。右海马高一致性和平衡状态的差异激活与个体特质回避倾向呈负相关。这些发现与当暴露于一致的AAT情境时，社会线索的情感神经加工减少一致。当评估情感一致性训练方案的有效性时，这些神经焦点可能是重要的目标。
Individuals exhibit a natural bias to approach positive social cues (e.g., smiling face) and to avoid negative ones, which may be altered in psychiatric conditions. Computerized approach/avoidance training to promote affectively congruent behavior has proven useful in modulating such biases. Here, we investigate how exposure to a higher rate of congruency impacts neural processing of social-affective cues. While undergoing functional magnetic resonance imaging (fMRI), twenty-four individuals completed two versions of the approach-avoidance task (AAT), in which they had to approach or avoid dynamic facial expressions of either happiness or disgust. In the high congruency condition, congruent responses (i.e. approaching happy faces, avoiding disgusted faces) were more frequent. The balanced condition had equal amounts of congruent and incongruent responses. Processing of congruent approach-avoidance actions towards social cues was associated with lower recruitment of the right anterior insula in the congruency-intensive relative to the balanced condition. Differential activation between the high congruency and balanced condition in the right hippocampus was negatively related to individuals’ trait avoidance tendency. These findings are consistent with reduced affective neural processing of social cues when being exposed to congruent AAT contexts. These neural foci could be important targets when assessing the effectiveness of affective congruency training protocols.
