hyperfocus
This term describes a state of cognitive absorption that goes beyond typical concentration. It is frequently associated with neurodivergence, particularly ADHD and autism, where the individual becomes so engrossed in a task that they lose awareness of time and their physical surroundings. While "focus" is generally viewed as a positive skill, "hyperfocus" often carries a nuance of lack of control, implying an inability to shift attention away from the object of interest even when it becomes counterproductive or socially inappropriate.
Meanings
