【摘要】 随着移动互联网技术的发展,移动短视频越来越受大众欢迎,特别是喜爱追赶潮流的大学生,但是短视频过度使用会带来一系列的负面影响,相关研究发现短视频过度使用显著降低了大学生的主观幸福感,还导致了成绩降低、注意力分散以及时间管理不善等问题。认知控制(Cognitive Control)指的是一系列具有挑战性的自上而下的心理过程。认知控制有三个主要组成部分,分别为抑制控制、工作记忆和认知灵活性。但以往研究却未探讨短视频过度使用与认知控制的关系及其作用机制。为了更全面地了解短视频过度使用对大学生认知控制功能的影响及其作用机制,本研究探讨短视频过度使用与认知控制的关系,以及在两者关系中走神的中介作用。走神(Mind Wandering,MW)是指注意从当前任务或者外部事件转移到内部自发思维和情感的一种现象。研究中采用了短视频过度使用量表、执行控制自评量表以及白日梦量表对180名在校大学生进行调查,研究结果表明:(1)短视频过度使用与认知控制之间存在显著相关,短视频使用越频繁,认知控制能力越差。(2)短视频过度使用与认知控制的三个子成分,抑制控制、工作记忆以及认知灵活性也存在显著正相关。(3)走神在短视频过度使用与认知控制之间起部分中介作用。本研究证实了过度使用短视频的确对大学生的认知控制能力有负面影响,有利于让用户合理安排短视频使用时间,防止沉迷。也能够为短视频应用防沉迷体系的后续优化措施提供新的思路,同时对网络监管部门规范短视频平台的运行提供一定的依据。更多还原

【Abstract】 With the development of mobile Internet technology, mobile Short-form Video are becoming more and more popular with the public, especially college students who like to catch up with the trend, but the excessive use of Short-form Video will bring a series of negative effects, and relevant studies have found that excessive use of Short-form Video significantly reduces the subjective well-being of college students, and also leads to problems such as reduced grades, distraction and poor time management. Cognitive control refers to a series of challenging top-down mental processes. Cognitive control has three main components, namely inhibitory control, working memory, and cognitive flexibility. However, previous studies have not explored the relationship between Short-form Video overuse and cognitive control and its mechanism. In order to understand the impact of Short-form Video overuse on college students’ cognitive control function, this study explores the relationship between Short-form Video overuse and cognitive control, and the mediating role of mind wandering in the relationship between the two. Mind Wandering(MW) refers to a phenomenon in which attention shifts from the current task or external event to internal spontaneous thinking and emotion. In this study, the Short-form Video overuse scale and the executive control self-rating scale were used to survey 180 college students, and the results showed that:(1) there was a significant correlation between Short-form Video overuse and cognitive control, and the more frequent the use of Short-form Video, the worse the cognitive control ability.(2) There was also a significant positive correlation between the overuse of Short-form Video and the three subcomponents of cognitive control, inhibition control, working memory and cognitive flexibility.(3) Mind wandering plays a partial mediating role between overuse of Short-form Video and cognitive control. This study confirms that excessive use of Short-form Videos does have a negative impact on the cognitive control ability of college students, which is conducive to allowing users to reasonably arrange the use of Short-form Video and prevent addiction. It can also provide new ideas for the subsequent optimization measures of the anti-addiction system for Short-form Video applications, and provide a certain basis for network regulatory authorities to standardize the operation of Short-form Video platforms.更多还原
