- Measured by:
- A word recognition test, then performance on the following task
Attention residue is the part of attention that stays on a task after the person has moved to the next one. Sophie Leroy measured it in 2009. People pulled away from an unfinished task performed worse on the following task than people who had finished the first one against a deadline. The previous task kept running in the background.
A workday of quick checks is a workday of stacked residue. Each glance at an inbox opens a task that stays open. The cost is paid during the following hour, on work that looked protected. Leroy found that residue shrinks when the first task is finished under time pressure, and when the stopping point is written down before the switch.
