摘　　要：为探究疫情和体力活动在短期和长期内的变化是否对记忆产生了影响,本研究以261名大学生为对象,采用问卷和记忆任务进行了线上追踪研究。结果表明,随着疫情在短期内的好转,体力活动没有显著变化,但伴随着项目记忆的下降和源记忆的上升;随着疫情在长期内的好转,体力活动显著回升,在项目记忆上有显著下降。另外,体力活动的回升没有影响记忆功能。因此,疫情变化对记忆的影响是直接的,而非通过体力活动。This study aimed to investigate whether short/long-term changes in COVID-19 and physical activity exerted an impact on memory functions.To provide insight into this question,261 college students were invited to participate in the longitudinal study.All students completed online questionnaires and memory tasks.The results showed that with the short-term improvement in epidemic,there was no significant change in physical activity,but there existed significant decrease in item memory and significant increase in source memory.With the long-term improvement in epidemic,significant increase and decline were separately observed in physical activity and item memory.The increase of physical activity did not exert a positive effect on memory functions.Therefore,the effect of COVID-19 on memory was direct,not through physical activity.
