本文综述了50-60 Hz弱电场、弱磁场及电磁复合场暴露对认知功能如记忆、注意力、信息处理和时间知觉的影响。总体而言，研究工频场对人类认知功能的急性影响的实验室研究在电场和磁场（EMF）暴露以及使用的实验设计和措施方面是异质的。结果不一致，难以解释可能的健康风险的功能相关性。现场和对照暴露之间的统计学显著性差异（当发现时）很小、微妙、短暂，没有任何明确的剂量-反应关系，难以重现。无法更好地确定可能特别受到EMF暴露影响的人类表现或事件相关电位（ERP）测量，以及可能对EMF更敏感的大脑结构或功能。
This paper reviews the effect of 50-60 Hz weak electric, magnetic and combined electric and magnetic field exposure on cognitive functions such as memory, attention, information processing and time perception, as determined by electroencephalo-graphic methods and performance measures. Overall, laboratory studies that have investigated the acute effects of power frequency fields on cognitive functioning in humans are heterogeneous, in terms of both electric and magnetic field (EMF) exposure and the experimental design and measures used. Results are inconsistent and difficult to interpret with regard to functional relevance for possible health risks. Statistically significant differences between field and control exposure, when they are found, are small, subtle, transitory, without any clear dose-response relationship and difficult to reproduce. The human performance or event related potentials, (ERPs) measures that might specifically be affected by EMF exposure, as well as a possible cerebral structure or function that could be more sensitive to EMF, cannot be better determined.
