模糊容忍力是形容个体对事物模糊属性容忍程度的心理变量，它作为一种稳定的人格变量潜移默化地影响着人们的日常生活。疫情以来，青少年的学习受疫情防控政策的影响长期处于不稳定环境之下，随着全面开放政策的实施，社会舆论关于未来不确定性、复杂性的讨论持续发酵。而青少年的思维尚处于发展阶段，缺乏对社会运行规律的深入思考，加之全面开放政策的实施临近期末考试，复杂多变背景下青少年学习效果与心理健康状况值得我们关注与研究。

通过调查A省B市两所学校高二、高三共200名学生模糊容忍力状况，结合其2022年12月与2023年2-3月语文考试成绩，使用相关分析、回归分析等统计方法对数据进行归纳解释，分析疫情不同时期模糊容忍力与学生语文学习成绩的相关性。

基于数据分析结果主要形成以下结论：第一，高中生模糊容忍力整体呈中等偏上水平；纵向来看，高三学生模糊容忍力平均值高于高二学生；横向来看，同年级学生中文科生模糊容忍力平均值高于理科生。第二，疫情期间模糊容忍力与语文学习成绩呈显著性正相关，不同刺激类型对不同年级的影响存在差异。第三，在日常学习中，模糊容忍力对学生学业成绩的积极影响和消极影响兼具。青少年是国家未来发展的栋梁，上述发现能够为学校教育、家庭教育提供相应策略，为我国人才培养提供有益助力。

Tolerance of ambiguity is a psychological variable that describes the degree of individual tolerance for the fuzzy attributes of things, and it subtly influences people's daily life as a stable personality variable. Since the COVID-19 epidemic, adolescents' learning has been under the influence of the epidemic prevention and control policy for a long time in an unstable environment, and with the implementation of the comprehensive opening policy, the discussion of social opinion about the uncertainty and complexity of the future has continued to ferment. The adolescents' thinking is still in the developmental stage, and they lack in-depth thinking about the laws of social operation. In addition, the implementation of the comprehensive open policy is close to the final examinations, and the adolescents' learning effect and psychological health in the complex and changing background deserve our attention and research.

By investigating the current situation of tolerance of ambiguity of a total of 200 students in sophomores and juniors in two schools in city B, province A, and combining their language examination results in December 2022 and February-March 2023, we used statistical methods such as correlation analysis and regression analysis to inductively interpret the data and analyze the correlation between tolerance of ambiguity and students' language learning performance in different periods of the epidemic.

Based on the results of data analysis, the following conclusions were mainly formed: first, the overall tolerance of ambiguity of high school students showed a moderate to high level; vertically, the mean value of tolerance of ambiguity of senior students was higher than that of sophomore students; in a horizontal comparison, the mean value of tolerance of ambiguity of students in the same grade was higher than that of science students. Second, tolerance of ambiguity during the epidemic was significantly and positively correlated with language learning performance, and there were differences in the effects of different stimulus types on different grades. Third, tolerance of ambiguity has both positive and negative effects on students' academic performance in daily learning. As adolescents are the pillars of the country's future development, the above findings can provide appropriate strategies for school education and family education, and provide a useful contribution to the cultivation of talents in China.
