Dangerous goods marks are the most effective means of alerting individuals to the potential dangers associated with the transport of dangerous goods. In order to gain a better understanding of how dangerous goods marks convey risk information, the cognitive processing of dangerous goods marks was examined by measuring event-related potentials (ERPs). We recruited 23 participants, and their ERP data were recorded. We discovered that the dangerous goods marks elicited a larger P200 amplitude and a smaller N300 amplitude, indicating that, compared to other marks, the dangerous goods marks exhibited stronger warning information and drew more attention from the subjects. Simultaneously, dangerous goods marks elicited insufficient emotional arousal in individuals. Therefore, these findings suggest that the designs of dangerous goods marks need to be improved, such as improving the graphic consistency. Changes in ERP patterns can be used to measure the risk perception level of dangerous goods marks, which can be used as an accurate indicator of the effectiveness of warning sign design. In addition, this study provides a theoretical foundation for the cognitive understanding mechanism of dangerous goods marks.
危险货物标志是提醒个人注意危险货物运输潜在危险的最有效手段。为了更好地了解危险货物标志如何传达风险信息，我们通过测量事件相关电位（ERP）来研究危险货物标志的认知加工。我们招募了 23 名参与者，并记录了他们的 ERP 数据。我们发现，危险货物标志引起的 P200 振幅较大，N300 振幅较小，这表明与其他标志相比，危险货物标志具有更强的警告信息，引起了受试者更多的注意。同时，危险货物标志在个体中引起的情绪唤醒不足。因此，这些发现表明需要改进危险货物标志的设计，例如提高图形一致性。ERP 模式的变化可用于衡量危险货物标志的风险感知水平，可作为警告标志设计有效性的准确指标。此外，本研究为危险货物标志的认知理解机制提供了理论基础。
