短视频问题性使用对抑制控制的影响

The Influence of Problematic Short‑Form Video Use on Inhibitory Control

摘要: 短视频已成为主流媒介，其问题性使用对执行功能的影响引发关注。抑制控制作为执行功能的核心成分，与短视频问题性使用紧密关联。本文系统梳理了短视频问题性使用的概念界定、测量工具及影响因素，重点综述了其与抑制控制关系的理论框架与实证证据。基于I-PACE模型，短视频问题性使用与抑制控制受损之间存在恶性循环：一方面，长期沉浸于碎片化、高刺激的短视频信息中会持续损耗抑制控制；另一方面，抑制控制薄弱者更难以抵御使用冲动，从而加剧行为失控。现有研究多以横断研究为主，且多采用一般性“冷”范式，对问题性使用者在短视频相关“热”情境下的抑制控制特征关注不足。未来研究应着力于与短视频线索相关的抑制控制任务以区分“冷”“热”下抑制机制的不同特点、开展纵向追踪与干预研究以厘清因果关系，并探索保护性因素的缓冲作用。

Abstract: Short-form videos have become a mainstream medium, and the impact of their problematic use on executive functions has drawn increasing attention. Inhibitory control, as a core component of executive function, is closely associated with problematic short-form video use. This paper systematically reviews the conceptual definition, measurement tools, and influencing factors of problematic short-form video use, with a particular focus on the theoretical frameworks and empirical evidence concerning its relationship with inhibitory control. Based on the I-PACE model, a vicious cycle exists between problematic short-form video use and impaired inhibitory control: on the one hand, prolonged immersion in fragmented, highly stimulating short-form video information continuously depletes inhibitory control; on the other hand, individuals with weaker inhibitory control find it more difficult to resist usage urges, thereby exacerbating behavioral dysregulation. Existing studies are predominantly cross-sectional and mostly employ general “cold” paradigms, paying insufficient attention to the inhibitory control characteristics of problematic users in short-video-related “hot” contexts. Future research should focus on developing inhibitory control tasks involving short-video cues to distinguish the different mechanisms of inhibition under “cold” versus “hot” conditions, conduct longitudinal tracking and intervention studies to clarify causal relationships, and explore the buffering effects of protective factors.
