We investigate the performance consequences of on-screen interruptions in mobile use. Drawing on capacity theory of attention, we conjecture that attention capacity may be lower in mobile use relative to PC use. A self-report instrument provides preliminary support for this conjecture. An online experiment provides additional support by showing that mobile users benefit from lower switching costs when they turn their attention to an interrupting task, while they suffer higher resumption costs when they resume a task that already demanded their attention. This study advances the understanding of mobile behavior while contributing to the broader literature on attention and interference.

中断时代的移动使用：容量和结构干扰对移动用户的影响


我们调查了移动使用中屏幕中断对性能的影响。借鉴注意力的容量理论，我们推测相对于 PC 使用，移动设备使用的注意力容量可能较低。自我报告工具为这一猜想提供了初步支持。一项在线实验提供了额外的支持，它表明，当移动用户将注意力转向中断任务时，他们受益于较低的切换成本，而当他们恢复已经需要他们注意的任务时，他们遭受更高的恢复成本。这项研究促进了对移动行为的理解，同时为关于注意力和干扰的更广泛文献做出了贡献。
