冲突适应是指经历冲突后产生的冲突控制能力的提高，是适应性认知控制的重要指标。冲突适应的逆转可能是适应不良和某些精神障碍的前兆。本研究采用基于实时功能近红外光谱的神经反馈训练，以左背外侧前额叶皮层为目标脑区，研究在单词颜色Stroop任务中冲突适应的逆转是否可以恢复到正常状态。将前测试中具有冲突适应逆转模式的健康人随机分为实验组和对照组。与接受虚假神经反馈的对照组相比，接受真实神经反馈的实验组接受了80分钟的分布式训练，取得了更大的改善。这些结果为理解冲突适应的产生提供了因果证据，并提高了神经反馈训练的临床应用前景。
Conflict adaptation refers to the improved conflict control induced after experiencing conflict and is a prominent index of adaptive cognitive control. Reversal of conflict adaptation may be maladaptive and predictive of certain mental disorders. Here, we employed real-time functional near infrared spectroscopy-based neurofeedback training, with the left dorsolateral prefrontal cortex as the target brain area, to investigate whether reversal of conflict adaptation during a word-color Stroop task could be recovered to be normal. Healthy human individuals with reversal pattern of conflict adaptation in the pretest were randomly assigned into the experimental or control groups. Distributed training for 80 min led to greater improvements in the experimental group who received real neurofeedback compared to those in the control group who received sham neurofeedback. These results indicated causal evidence for understanding the generation of conflict adaptation and heighten the prospects of clinical application of neurofeedback training.
