Collective attention under digital exposure: A dynamical systems approach
A new physics model shows how continuous screen exposure degrades collective attention without social contagion.
A new physics paper by researcher Nuno Crokidakis, titled 'Collective attention under digital exposure: A dynamical systems approach,' applies dynamical systems theory to model how digital screen exposure degrades population-level attention. Published on arXiv (identifier 2604.02059), the work introduces a macroscopic variable representing the average level of sustained attention. The model frames its dynamics as a competition between intrinsic cognitive recovery and degradation induced by continuous digital stimulation, treating the digital environment as an external control parameter that perturbs the system.
The analysis progresses from a linear, analytically tractable formulation to a nonlinear model that captures amplification effects under high-intensity stimulation. A key finding is an explicit expression for the stationary state, showing that the equilibrium attention level decreases monotonically as exposure increases. The paper introduces an effective potential formulation, revealing that digital overstimulation progressively deforms the dynamical landscape, shifting the stable state toward regimes of reduced attention without creating multiple equilibria.
Crucially, the model departs from social science approaches that rely on social contagion or interaction-driven bistability. Instead, it describes a continuous displacement of the collective cognitive regime under persistent environmental pressure. The 18-page paper, submitted for publication, suggests the impact of digital technology on attention can be understood as a gradual macroscopic effect emerging from external stimulation, rather than a sharp transition between behavioral states. This physics-based framework provides a new, quantitative lens for a pressing societal concern.
- Models attention as a dynamical system with recovery/degradation competition, treating digital exposure as an external control parameter.
- Shows equilibrium attention decreases monotonically with exposure; overstimulation deforms the potential landscape toward lower attention.
- Proposes impact is a continuous macroscopic displacement from environmental pressure, not a bistable transition driven by social contagion.
