【摘要】 目的：从行为与神经电生理层面上考察中等强度体育锻炼对人际关系困扰大学生的人际冲突信息知觉的影响。方法：招募62名高人际关系困扰的非体育专业本科生，随机分配到实验组和对照组，其中实验组进行为期12周、每周3次、每次累计30至35分钟的中等强度体育锻炼，对照组不进行干预。锻炼干预前后测均采用Koban的社会资源冲突任务评估人际冲突信息知觉，收集行为和ERP数据并分析。结果：(1)在正确率上，对照组被试的冲突信息知觉平均正确率显著低于实验组被试，在反应时上，人际关系困扰大学生在无冲突情境下反应速度显著更快，此外，随着时间的推移，被试平均反应时间有显著下降；(2)冲突情境下的P1平均波幅高于无冲突情境，而N2平均波幅在冲突下略有下降；(3)冲突情境下的P3波幅显著高于无冲突情境，时间、组别与冲突类型的交互作用显著；(4)LPP的平均波幅在后测时低于前测，冲突情境下显著高于无冲突情境，时间与组别交互作用显著。结论：面对冲突信息时，大学生表现出明显的警觉性和快速反应能力。中等强度体育锻炼提高了人际关系困扰大学生在人际冲突信息知觉上的正确率，加快了被试对人际冲突信息的感知效率。同时，中等强度体育锻炼有效增强了人际关系困扰大学生在知觉加工过程中对冲突信息的认知控制能力(P3),使其情绪稳定、认知高效(LPP),更加准确地判断冲突信息。更多还原

【Abstract】 Aim: To investigate the effects of moderate intensity physical exercise on the perception of conflict information in interpersonal disturbance in college students from behavioral and neuro electrophysiological aspects. Methods: 62 non-physical education undergraduates with high interpersonal disturbance were recruited and randomly assigned to the experimental group and the control group. The experimental group performed 30～35 minutes of moderate intensity physical exercise three times a week for 12 weeks, while the control group did not intervene. Koban’s social resource conflict task was used to assess interpersonal conflict information perception before and after exercise intervention, and behavioral and ERP data were collected and analyzed. Results: In terms of accuracy, the average accuracy of conflict information perception of the control group was significantly lower than that of the experimental group, in terms of reaction time, interpersonal relationship troubled college students responded significantly faster in the non-conflict situation, in addition, with the passage of time, the average reaction time of the subjects decreased significantly; the mean amplitude of P1 in the conflict situation is higher than that in the non-conflict situation, while the mean amplitude of N2 is slightly decreased in the conflict situation; the P3 amplitude in the conflict situation was significantly higher than that in the non-conflict situation, and the interaction between time, group and conflict type was significant; the average amplitude of LPP was lower in the post-test than in the pre-test, and significantly higher in the conflict situation than in the non-conflict situation, and the interaction between time and group was significant. Conclusion: In the face of conflict information, college students showed obvious alertness and rapid response ability. The moderate intensity physical exercise can improve the correct rate of interpersonal conflict information perception and speed up the perception efficiency of interpersonal conflict information. At the same time, moderate intensity physical exercise effectively enhanced the cognitive control ability(P3), emotional stability and cognitive efficiency(LPP) of interpersonal disturbance college students in the process of perceptual processing of conflict information, and more accurately judge conflict information.更多还原
