Recent advancements in portable computer devices have opened new avenues in the study of human cognition outside research laboratories. This flexibility in methodology has led to the publication of several electroencephalography studies recording brain responses in real-world scenarios such as cycling and walking outside. In the present study, we tested the classic auditory oddball task while participants moved around an indoor running track using an electric skateboard. This novel approach allows for the study of attention in motion while virtually removing body movement. Using the skateboard auditory oddball paradigm, we found reliable and expected standard-target differences in the P3 and MMN/N2b event-related potentials. We also recorded baseline electroencephalography activity and found that, compared to this baseline, alpha power is attenuated in frontal and parietal regions during skateboarding. In order to explore the influence of motor interference in cognitive resources during skateboarding, we compared participants' preferred riding stance (baseline level of riding difficulty) versus their non-preferred stance (increased level of riding difficulty). We found that an increase in riding difficulty did not modulate the P3 and tonic alpha amplitude during skateboard motion. These results suggest that increases in motor demands might not lead to reductions in cognitive resources as shown in previous literature.
最近便携式计算机设备的进步为在研究实验室之外研究人类认知开辟了新途径。这种方法的灵活性导致了几项脑电图研究的发表，这些研究记录了在现实场景中的大脑反应，例如在户外骑自行车和散步。在本研究中，我们使用电动滑板在室内跑步道上让参与者移动，测试了经典的听觉Oddball 任务。这种新颖的方法允许在运动中研究注意力，同时几乎消除了身体运动。使用滑板听觉Oddball 范式，我们发现 P3 和 MMN/N2b 事件相关电位中存在可靠且预期的标准-靶标差异。我们还记录了脑电图的基线活动，发现与基线相比，在滑板运动期间，额叶和顶叶区域的α功率减弱。为了探索滑板运动期间运动干扰对认知资源的影响，我们比较了参与者的首选骑行姿势（基线骑行难度水平）与非首选姿势（增加的骑行难度水平）。我们发现，骑行难度的增加并没有调节滑板运动期间的 P3 和紧张性α波幅度。这些结果表明，与之前文献中的结果不同，运动需求的增加不一定会导致认知资源的减少。
