This review appraises electroencephalograph (EEG) approaches to cognitive workload evaluation, focussing on the measurement of event-related potentials (ERPs) in single task paradigms. A systematic search was undertaken, studies were included if they used a single task paradigm with an auditory stimulus combined with ERP measures from EEG to evaluate cognitive workload in healthy adults. Nineteen articles met the inclusion criteria. There was a change in the amplitude of ERP components with an increase in cognitive difficulty. However, this change was dependent on the features of the task and stimuli. This review emphasizes the importance of stimulus and task selection in single task paradigms to evaluate cognitive workload. This review also synthesizes important concepts regarding ERPs in single task paradigms such as the effect of primary task selection on specific ERP components.

这项审查评估脑电图（EEG）的方法来评估认知工作量，重点是在单个任务范式中的事件相关电位（ERP）的测量。进行了系统的搜索，如果他们使用带有听觉刺激的单一任务范式结合EEG的ERP措施来评估健康成年人的认知负荷，则将其纳入研究。符合纳入标准的文章有19篇。随着认知难度的增加，ERP组件的幅度发生了变化。但是，这种变化取决于任务和刺激的特征。这篇综述强调了刺激和任务选择在单任务范式中评估认知工作量的重要性。
