Selective attention is the ability to prioritize some information while giving less weight to other information. Human Precision constantly asks you to decide which parts of the moving field deserve attention first.
Not every object deserves the same focus
A wall already behind the ball no longer matters. A distant wall may matter soon, but the next opening usually deserves priority. Strong play comes from shifting attention without losing the immediate path.
Visual clutter can create bad corrections
If you react to every shape equally, cursor movement becomes noisy. The task rewards choosing a path and making only the corrections needed to stay inside it.
This is still a game
Performance can reflect attention, but it also reflects motor skill, practice, hardware, and strategy. The score is not a clinical attention assessment.
