随着移动互联网的持续进步、5G技术的推进和智能手机的广泛使用，短视频以其丰富的内容类型和逐渐增强的社交属性，成为基础的用户表达和内容消费形式，贡献了移动互联网的主要时长和流量增量。这种新兴的传播模式适应了移动互联网的碎片化和去中心化的传播特性，不仅具有较小的体量和高密度的信息，还具备快速的传播速度和高效的推荐算法，使其在媒介生态系统中的地位不断提升。
目前，传播学领域还未有大脑执行功能与短视频使用之间关系的相关研究。执行功能是人脑的指挥功能，负责管理和调控其他如感知觉、记忆等低级认知过程，广泛影响着人类生活的方方面面，是人类认知的核心功能。本研究利用传播学、心理学、认知神经科学等多元学科理论，深入探究短视频的使用行为对大脑执行功能的影响，并引用心理学模型和统计分析对二者的关系进行定量分析。
本研究采用问卷调查、认知任务测量以及脑电图（EEG）记录等一系列方法，全面分析了短视频使用行为与执行功能之间的联系。研究通过对短视频使用的客观数据与主观评价进行综合分析，发现频繁观看短视频与个体时间感知能力之间存在紧密联系，可能会导致出现“时间扭曲”现象，即用户对短视频使用时长的感知出现明显偏差。此外，本研究通过对执行功能相关的认知任务评估，发现短视频使用时长的增加与执行功能的减弱存在关联，尤其在重度用户中，表现为抑制控制能力的降低和工作记忆水平的下降。
在本研究的主观报告中，参与者普遍认为短视频的频繁使用对其工作和学习效率产生了一定程度的影响。本研究通过EEG数据分析，进一步揭示了短视频使用对脑功能的潜在影响，发现重度用户在Theta波段能量上存在显著差异，表现为Theta频段的能量显著升高，而在Alpha和Beta波段能量上没有显著变化。鉴于Theta波段能量的升高与抑制控制和复杂决策负载相关，所以短视频的过度使用可能会干扰与执行控制能力相关的大脑区域，从而影响相关的脑电活动，进而影响成年人的执行功能表现。
本研究通过问卷调查与实验法相结合的方式，进行大脑活动数据的采集和分析，深入探究成年人大脑执行功能与短视频使用行为之间的关系，丰富认知神经传播学领域针对短视频使用与认知行为的研究，帮助人们理解短视频媒介对个体大脑认知的影响，从而更清楚、理性地看待短视频应用。

With the maturity of mobile Internet, the upgrade of 5G technology and the popularity of smart phones, short video has become a basic form of user expression and content consumption with its rich content types and enhanced social attributes, contributing to the main duration and traffic increment of mobile Internet. This new communication style aligns with the mobile Internet's fragmented and decentralized nature. It is not only small in size and large in information density, but also has fast transmission speed and high recommendation algorithm efficiency, and its status in the media ecology continues to rise.
At present, there are no relevant studies on the relationship between brain executive function and short video use in the field of communication. Executive function is the command function of human brain, which is responsible for managing and regulating other low-level cognitive processes such as perception, memory and so on. It has a wide impact on all aspects of human life and is the core function of human cognition. This study uses multi-disciplinary theories such as communication, psychology and cognitive neuroscience to deeply explore the impact of short video usage on brain executive function, and uses psychological models and statistical analysis to conduct a quantitative analysis of the relationship between the two. 
This study used a series of methods including questionnaire survey, cognitive task measurements and electroencephalography (EEG) recordings to comprehensively analyze the relationship between short video usage behavior and executive function. Through a combined analysis of objective data on short video use and subjective evaluations, the study unveils a close link between frequent short video viewing and individuals' perception of time, finding that it may lead to a "time distortion" phenomenon, where the perception of time spent on short videos is significantly skewed. Moreover, by assessing cognitive tasks related to executive functions, the study discovers that an increase in short video usage duration is associated with a decline in executive functions, particularly among heavy users, manifested as a reduction in inhibitory control abilities and a decrease in working memory levels. 
This study further revealed the potential impact of short video use on brain function through EEG data analysis, and found that heavy users had significant differences in Theta wave energy, characterized by a significant increase in theta wave energy, while no significant changes were observed in the alpha and beta wave energies. Considering that an increase in theta wave energy is related to inhibitory control and complex decision-making loads, the excessive use of short videos may interfere with brain regions associated with executive control abilities, thereby affecting related brain electrical activity and ultimately impacting adult executive function performance. 
Through the combination of questionnaire survey and experiment method, this study collected and analyzed brain activity data to deeply explore the relationship between adult brain executive function and short video use behavior. It not only enriches the research on short video use and cognitive behavior in the field of Cognitive Neuroscience and Communication, but also helps people understand the impact of short video media on individual brain cognition, so as to view the application of short video more clearly and rationally.
