Digital technologies have altered children’s attention in three main ways:

  1. Increased distractibility
  • Frequent multitasking and app-driven notifications shorten sustained-attention episodes and make switching between tasks more common (Rosen et al., 2013; Uncapher & Wagner, 2018).
  1. Shorter sustained attention, different attentional skills
  • Time spent with fast-paced, highly stimulating media is associated with reduced ability to maintain prolonged focus on low-stimulation tasks; at the same time, children develop enhanced skills for rapid attention shifts and scanning multiple streams of information (Christakis, 2009; Lillard & Peterson, 2011).
  1. Context-dependent effects (quality, quantity, and content matter)
  • Educational, interactive, and well-designed digital content can support focused learning and executive function; excessive, inappropriate, or fragmented use (especially before sleep) worsens concentration and self-regulation (Hinkley et al., 2019; Przybylski & Weinstein, 2019).

Underlying mechanisms include altered reward sensitivity (immediate feedback loops), sleep disruption from screen use, and reduced practice with sustained, undistracted tasks. Overall effect is mixed: digital tech can both undermine and enhance attention depending on how, how much, and what content is used.
