In the current study, we investigate the neuronal correlates of the Attention Training Technique (ATT), a psychotherapeutic intervention used in metacognitive therapy to enhance flexible cognitive control and ameliorate rumination. We adapted the ATT in a neuroscientific attention paradigm in order to investigate the effects of its components: selective attention, attention switching and divided attention in comparison to a control task. Functional near-infrared spectroscopy was used to measure changes in blood oxygenation of fronto-lateral and parietal cortical areas. Furthermore, subjects rated their task performance, effort and attention drifts in each task condition. We observed increased blood oxygenation in the right inferior frontal gyrus, right dorsolateral prefrontal cortex and superior parietal lobule during the ATT conditions in comparison to the control condition. Additionally, subjective effort was associated with blood oxygenation in the right inferior prefrontal cortex. Our results are consistent with the theoretical underpinnings of the ATT suggesting that the ATT's mechanism of change lies in the training of areas of the cognitive control network and dorsal attention network. Aberrant functioning of both networks has been shown to be related to depression and rumination.
在目前的研究中，我们调查了注意力训练技术（ATT）的神经相关性，这是一种认知疗法中使用的心理治疗干预措施，用于增强灵活的认知控制能力并改善反刍。我们在神经科学注意力范式中改编了 ATT，以研究其组成部分的效果：选择性注意、注意转换和分散注意，与控制任务进行比较。功能近红外光谱用于测量额侧和顶叶皮质区域的血氧变化。此外，受试者在每个任务条件下对自己的任务表现、努力程度和注意力漂移进行评分。与控制条件相比，我们观察到在 ATT 条件下，右侧额下回、右侧背外侧前额叶皮层和顶叶上回的血氧增加。此外，主观努力与右侧额下回的血氧有关。我们的结果与 ATT 的理论基础一致，表明 ATT 的变化机制在于认知控制网络和背侧注意网络的训练。这两个网络的异常功能已被证明与抑郁和反刍有关。
