This study aimed to investigate the neurocognitive effects of the Attention Training Technique (ATT) on brain activity in healthy participants. The participants included 20 university students who were asked to practice ATT as a homework assignment for 20 days. The intracerebral source localization of their electroencephalogram during rest and the ATT task, which comprised selective attention, attention switching, and divided attention conditions, was evaluated by standardized low-resolution brain electromagnetic tomography. Brain activity during rest was subtracted from that during the ATT task, and that was compared before and after the homework assignment. The results for the divided attention condition indicated significantly decreased alpha 1 frequency band power in the left orbital frontal cortex (OFC) and alpha 2 power in the right inferior temporal cortex. Further, decreased alpha 1 power in the left OFC correlated with reduced subjective difficulty during the divided attention condition. One possibility is that the brain activity changed as the effect of ATT practice, although this study cannot confirm causality. Further studies are required which include a control group that would complete similar training without the ATT task.

本研究旨在调查注意力训练技术 (ATT) 对健康参与者大脑活动的神经认知影响。参与者包括 20 名大学生，他们被要求将 ATT 作为家庭作业练习 20 天。通过标准化的低分辨率脑电磁断层扫描评估休息期间脑电图的脑内源定位和包括选择性注意、注意切换和分散注意条件的 ATT 任务。从 ATT 任务期间的大脑活动中减去休息期间的大脑活动，并在作业分配之前和之后进行比较。分散注意力条件的结果表明，左眶额叶皮层 (OFC) 的 alpha 1 频带功率和右下颞叶皮层的 alpha 2 功率显着降低。此外，左侧 OFC 中 alpha 1 功率的降低与注意力分散状态下主观难度的降低相关。一种可能性是，随着 ATT 练习的影响，大脑活动发生了变化，尽管这项研究无法证实因果关系。需要进一步的研究，其中包括一个对照组，该对照组将在没有 ATT 任务的情况下完成类似的培训。虽然这项研究无法证实因果关系。需要进一步的研究，其中包括一个对照组，该对照组将在没有 ATT 任务的情况下完成类似的培训。虽然这项研究无法证实因果关系。需要进一步的研究，其中包括一个对照组，该对照组将在没有 ATT 任务的情况下完成类似的培训。
