Visual Temporal Order Test: Which Light Came First?

Two beacons flash only milliseconds apart. Pick the one that appeared first; two correct answers shorten the gap and a miss lengthens it. Across 12 adaptive rounds, the task homes in on how finely your vision separates the order of two events. Equal rewards and penalties keep random guessing at zero.
