Follow the moving target with your eyes. When it briefly flashes green, click the button as fast as possible.
Why it matters
Following a smoothly moving object with your eyes while also noticing subtle changes — that's exactly what a defender does watching the ball, or a goalkeeper waiting for a change in shot spin. This test measures how long you can hold attention on a moving target without losing focus.
The ability to hold visual attention on a smoothly moving target over time and catch a subtle change before it disappears.
Athletes who need to track a moving object over extended periods while noticing changes (e.g. a change of direction), and anyone wanting to train visual endurance.
Rating scale
Smooth pursuit is one of the fundamental types of eye movement. Holding attention on a target during a longer, continuous tracking task while catching an embedded change is harder than it sounds — attention tends to "switch off" when a task feels monotonous.
