目的:类别决策是人类重要的认知方式之一,情景对类别决策的准确性具有重要影响,但并没有引起足够的重视,对其研究也较少。方法:本研究选取大学生被试,通过ERPs对大学生被试电生理水平探讨情境标签的作用。结果:在基于情境标签下的分类活动激活了更多的大脑区域,基于情景标签下被试分类的潜伏期更短,判断更加快速准确。结论:类别决策过程中情景标签有重要的作用,通过情景标签能提高类别决策能力。
OBJECTIVE: Category decision is one of the important cognitive modes of human beings. Scenarios have an important influence on the accuracy of category decision, but they have not attracted enough attention and studied less. Methods: In this study, college students were selected to investigate the role of context tags in the electrophysiological level of college students through ERPs. Results: More brain regions were activated based on classification activities under contextual tabulation. Subjects under scenario tagging had shorter incubation period and more rapid and accurate judgment. Conclusion: Scenario labeling plays an important role in the process of category decision making. Scenario labeling can improve the ability of category decision-making.
