Consumer-grade EEG devices, such as the InteraXon Muse 2 headband, present a promising opportunity to enhance the accessibility and inclusivity of neuroscience research. However, their effectiveness in capturing language-related ERP components, such as the N400, remains underexplored. This study thus aimed to investigate the feasibility of using the Muse 2 to measure the N400 effect in a semantic relatedness judgment task. Thirty-seven participants evaluated the semantic relatedness of word pairs while their EEG was recorded using the Muse 2. Single-trial ERPs were analyzed using robust Yuen -tests and hierarchical linear modeling (HLM) to assess the N400 difference between semantically related and unrelated target words. ERP analyses indicated a significantly larger N400 effect in response to unrelated word pairs over the right frontal electrode. Additionally, dependability estimates suggested acceptable internal consistency for the N400 data. Overall, these findings illustrate the capability of the Muse 2 to reliably measure the N400 effect, reinforcing its potential as a valuable tool for language research. This study highlights the potential of affordable, wearable EEG technology to expand access to brain research by offering an affordable and portable way to study language and cognition in diverse populations and settings.
消费级脑电图设备，如InteraXon Muse 2头带，为提高神经科学研究的可及性和包容性提供了一个很有前景的机会。然而，它们在捕捉与语言相关的事件相关电位（ERP）成分（如N400）方面的有效性仍未得到充分探索。因此，本研究旨在探讨使用Muse 2在语义相关性判断任务中测量N400效应的可行性。37名参与者在使用Muse 2记录脑电图的同时评估单词对的语义相关性。使用稳健的Yuen检验和分层线性模型（HLM）分析单次试验ERP，以评估语义相关和不相关目标词之间的N400差异。ERP分析表明，在右侧额叶电极上，对不相关单词对的反应中N400效应显著更大。此外，可靠性估计表明N400数据具有可接受的内部一致性。总体而言，这些发现说明了Muse 2能够可靠地测量N400效应，增强了其作为语言研究有价值工具的潜力。本研究强调了经济实惠的可穿戴脑电图技术通过提供一种经济实惠且便携的方式在不同人群和环境中研究语言和认知，从而扩大脑研究可及性的潜力。
