数字媒介使用与注意力功能的神经科学视角

The Attention Function in the Digital Age: A Neuroscience Perspective on Digital Media Use

摘要: 数字媒介的广泛使用与个体注意力功能的关系已成为一个重要研究议题。文章从神经科学视角，系统审视了二者之间的行为关联、潜在机制与评估方法。综述表明，某些特定的数字媒介使用模式(如频繁任务切换、被动滚动)与注意力分散化存在关联，其潜在机制可能涉及大脑默认模式网络与控制网络耦合方式的改变、神经振荡异步性等。同时，神经科学也推动了评估方法的革新，虚拟现实与神经同步性测量为在自然情境下量化注意力状态提供了新工具。本文进一步提出了一个整合性的“数字神经生态”理论框架，旨在阐释个体、神经与环境多层面因素之间的复杂交互作用，并指出未来研究应借助纵向设计与计算建模，探索针对注意力挑战的精准干预策略。

Abstract: The widespread use of digital media has made its relationship with attentional function a significant research topic. This article systematically examines the behavioral correlations, potential mechanisms, and assessment methods from a neuroscience perspective. A review reveals that specific patterns of digital media use (such as frequent task switching and passive scrolling) are associated with attentional fragmentation, with potential mechanisms involving alterations in the coupling between the brain’s default mode network and the control network, as well as inductions of asynchronous neural oscillations. Meanwhile, neuroscience has also spurred innovations in assessment paradigms. Virtual reality and neural synchrony measurement provide new tools for quantifying attentional states in naturalistic contexts. This paper further proposes an integrative “digital neural ecology” theoretical framework to explain the complex interactions among individual, neural, and environmental factors, and points out that future research should utilize longitudinal designs and computational modeling to explore precise intervention strategies for attentional challenges.
