摘要：This work intends to examine the influence of different dimensions of psychological distance on the moral decision-making of sports college students in sports dilemmas under different learning pressure conditions, and to further investigate the relationship between psychological distance and moral decision-making. The research on the influencing factors of moral decision-making of sports majors can effectively help to understand the moral cognition level of the group, and provide a reference for the interpretation of athletes’ moral anomie behavior, thereby enriching the content of the moral quality education of athletes. This work intends to study the impact of psychological distance on the moral decision support of sports college students in the context of the Internet of Things (IoT) and machine learning. Psychological distance in the machine learning environment may affect individuals’ understanding and cognition of events and, to a certain extent, can change students’ cognition and judgment of events. IoT and machine learning environments are chosen as the foundation. The learning pressure of college students majoring in physical education is a variable. A questionnaire survey and experimental design are used to test the influence of different degrees of learning pressure, social distance, and spatial distance on the moral decision-making of physical education college students in the sports dilemma. The dimensions of the psychological distance of physical education (PE) students are analyzed under different stress conditions and their impact on the moral decision-making of PE students. This experiment adopts a mixed experimental design of 3 learning stresses (no stress vs. moderate stress vs. high stress) × 2 social distances (self vs. others) × 2 spatial distances (Beijing vs. France). The results show that the main effect of social distance is significant. When the self is the decision-making subject, individuals tend to make more moral decisions. There is a significant interaction between social distance and learning pressure. In a stress-free and high-stress environment, individuals make a significant increase in the number of moral decisions when faced with self-centered decision-making. Now, moral decision-making and its consequences are important for college students majoring in sports. The results of their moral decision-making in the field of education directly reflect the image of the individual and even the institution.
