Monitoring
How many dots are there?
Fast white dots drift and overlap inside a dark circle — count them and pick the number as quickly as you can. Every correct answer speeds the dots up; every wrong one slows them down. Sustained monitoring under changing load is assessed throughout FEAST and the ATSA.

What to expect
- 6 to 11 white dots moving and overlapping in a circle.
- Five number options — pick how many dots there are.
- Correct = faster dots (+1), wrong = slower dots (-1).
What it measures
- Sustained attention
- Counting under movement and occlusion
- Speed–accuracy trade-off
Instructions
- 1Count the dots as they move and overlap.
- 2Pick the matching number; the dots then speed up or slow down.
- 3Keep a steady scan — don't lose count when they cross.
Tips
- Count in small groups rather than one by one.
- Overlapping dots still count separately.
Monitoring
Fast white dots drift and overlap inside a dark circle. You count them and pick the number as quickly as you can. Every correct answer makes the dots move faster; every wrong one slows them down, so the test finds your ceiling and holds you at it.
Counting things that occlude each other while they move is close to the real cognitive demand of scanning a display. The adaptive speed means your score reflects the limit of what you can do, not how many easy items you got through.
