Improvement in an individuals' cognition is the key to promote garbage classification. This study takes university students as the research subjects, through three educational interventions, including the self-learning, heuristic learning, and interactive learning ways, to seek the most effective intervention based upon event-related potentials (ERPs) that is beneficial to enhance cognition of garbage classification. The results show that the experimental subjects induced P300 and LPP components, representing attentional changes and cognitive conflicts in classification judgments. There are differences in the amplitudes and peak latency of the two components corresponding to different interventions, indicating that the three educational interventions are able to improve the individual's cognition level of garbage classification within a certain period of time. The interactive-learning intervention triggers the largest amplitudes of P300 and LPP, as well as the smallest peak latency, indicating its effect is the best. Such results provide insight into the design for an appropriate strategy in garbage classification education. The study also shows that an EEG signal can be used as the endogenous neural indicator to measure the performance of garbage classification under different educational interventions.
提高个体认知能力是促进垃圾分类的关键。本研究以大学生为研究对象,通过三种教育干预方式,包括自学、启发式学习和互动学习,利用事件相关电位(ERP)寻找最有效的干预方法,以提高垃圾分类认知能力。结果表明,实验对象诱发了 P300 和 LPP 成分,分别代表分类判断中注意力的变化和认知冲突。两种成分的振幅和峰潜伏期在不同的干预措施下存在差异,表明这三种教育干预措施可以在一定时间内提高个体的垃圾分类认知水平。互动学习干预引发了最大的 P300 和 LPP 振幅,以及最小的峰潜伏期,表明其效果最好。这些结果为垃圾分类教育中适当策略的设计提供了思路。该研究还表明,脑电图信号可以作为内源性神经指标,用于测量不同教育干预下的垃圾分类表现。
