Researchers report that attention moves in a repeating rhythm about seven to ten times per second. The rhythm means there are short moments when people notice things better and moments when they notice things less well.
Scientists at the University of Rochester used EEG, a brain recording method, and tested 40 participants. People looked at a dim grey square while coloured dots acted as distractors. The team removed any data with eye movements so the results showed internal attention shifts.
The study explains why sudden pop-ups or notifications often capture attention and why focus can feel unreliable in daily life.
