Nowadays, teaching and learning methods are constantly changing with the development and popularization of information technology. Many teaching activities are exploring the integration of virtual technology. However, the specific effects of VR are challenging to verify. In this paper, “teaching in VR environment” and “traditional teaching” were designed to carry out a series of teaching comparison practices between two groups of a primary school. By analyzing the experimental data of the experimental group and the control group, the research found that it is easier to enter mental flow in virtual reality, and the introduction of virtual reality technology is positively correlated with learning engagement. What is more, compared with traditional teaching and learning methods, virtual reality technology and related software can help individuals give full play to their creativity.

Community governance is the foundation of social governance and a guarantee for modernizing the national governance system and capacity. Residents’ satisfaction with community governance is an important factor in measuring community governance level. Based on similar related literature and practical research analysis, 18 influencing factors of community governance residents’ satisfaction were extracted from four dimensions. Through the principal component analysis of social science statistical software, 16 key influencing factors were finally selected, and six regression models were analyzed and compared. Further, they clarified the influence of various dimensions on residents’ satisfaction with community governance. Further analysis and research on the model show that community governance service, community education and community interpersonal communication are significantly positively correlated with residents’ satisfaction with community governance. Although participation in community governance as a single influencing factor has no significant effect in this study, it can also positively and significantly affect residents’ satisfaction with community governance under the joint action of community education and community interpersonal communication. Therefore, from the aspects of improving the service level of community governance, enhancing the participation of community governance in multiple ways, giving full attention to the role of community education and shaping the new model of community communication, a more realistic evaluation system of community governance residents’ satisfaction is designed.

Numerous studies have traditionally employed monetary incentives to investigate reward and loss processing in individuals exhibiting depressive symptoms, despite the fact that depression often arises and persists due to maladaptive responses to social rewards and losses.In this study, we explored the responses of individuals with mild depression under different reward tasks and reward probabilities and further clarified the psychological mechanism of individuals with mild depression under reward and loss. 57 participants with mild depression and 57 healthy controls (HC) completed the monetary incentive delay (MID) and social incentive delay (SID) tasks. The results revealed that there was no interaction between reward task and group reaction time(RT). Responses of the two groups in MID and SID were similar. Under conditions of high reward probability, the reaction time of the HC was distinctively shorter than that of the group with mild depression, while there was no difference between the two groups under low reward probability conditions. In conclusion, individuals with mild depression demonstrate a more pronounced impairment in their reward function under conditions of high reward probability. They exhibit normal responses to monetary loss and and social negation under conditions of low reward probability.
