While the psychological predictors of antiscience beliefs have been extensively studied, neural underpinnings of the antiscience beliefs have received relatively little interest. The aim of the current study is to investigate whether attitudes towards the scientific issues are reflected in the N400 potential. Thirty-one individuals were asked to judge whether six different issues presented as primes (vaccines, medicines, nuclear energy, solar energy, genetically-modified organisms (GMO), natural farming) are well-described by ten positive and ten negative target words. EEG was recorded during the task. Furthermore, participants were asked to rate their own expertise in each of the six topics. Both positive and negative target words related to GMO elicited larger N400, than targets associated with vaccines and natural farming. The results of the current study show that N400 may be an indicator of the ambiguous attitude toward scientific issues.
虽然反科学信仰的心理预测因素已经得到了广泛的研究，但反科学信仰的神经基础却相对较少受到关注。本研究的目的是探讨对科学问题的态度是否反映在 N400 电位中。31 名参与者被要求判断六个不同的问题（疫苗、药物、核能、太阳能、转基因生物（GMO）、自然农业）是否被十个正词和十个负词很好地描述。在任务期间记录 EEG。此外，参与者被要求对他们在六个主题中的每个主题的专业知识进行评分。与 GMO 相关的正词和负词都比与疫苗和自然农业相关的目标词诱发了更大的 N400。本研究的结果表明，N400 可能是对科学问题的模糊态度的指标。
