Attention Residue by Sophie Leroy. Here.
I’ve spent the last 17 years studying the brain and how we deal with having to constantly switch focus. What research shows is that, generally, the brain finds it difficult to switch between tasks. In particular, my research reveals that, as we switch between tasks (for example from a Task A to a Task B), part of our attention often stays with the prior task (Task A) instead of fully transferring to the next one (Task B). This is what I call Attention Residue, when part of our attention is focused on another task instead of being fully devoted to the current task that needs to be performed.
Seems relevant these days.
