Cognitive Residue
Topic
Cognitive residue (more commonly known as attention residue) is a psychological phenomenon where a person's cognitive capacity and focus remain partially attached to a prior task after switching to a new one. Coined by researcher Sophie Leroy in 2009, this lingering mental activation reduces performance and efficiency on the subsequent task, highlighting the hidden productivity costs of multitasking and frequent context switching.
