Given the rapid development of light weight EEG devices which we have witnessed the past decade, it is reasonable to ask to which extent neuroscience could now be taken outside the lab. In this study, we have designed an EEG paradigm well suited for deployment "in the wild." The paradigm is tested in repeated recordings on 20 subjects, on eight different occasions (4 in the laboratory, 4 in the subject's own home). By calculating the inter subject, intra subject and inter location variance, we find that the inter location variation for this paradigm is considerably less than the inter subject variation. We believe the paradigm is representative of a large group of other relevant paradigms. This means that given the positive results in this study, we find that if a research paradigm would benefit from being performed in less controlled environments, we expect limited problems in doing so.
鉴于我们在过去十年中目睹的轻型脑电图设备的快速发展,合理的问题是神经科学现在可以在多大程度上走出实验室。在这项研究中,我们设计了一种非常适合在“自然环境”中部署的脑电图范式。该范式在20名受试者的重复记录中进行了测试,在八个不同的场合(4次在实验室,4次在受试者自己家中)。通过计算受试者间、受试者内和地点间的方差,我们发现该范式的地点间变化远小于受试者间变化。我们认为该范式代表了一大批其他相关范式。这意味着,鉴于本研究的积极结果,我们发现,如果一种研究范式在控制较少的环境中进行会受益,那么我们预计这样做会遇到有限的问题。
