About Number Comparison

Number Sense

This test measures your numerical cognition -- how quickly your brain processes and compares quantities. Faster comparisons indicate stronger number sense.

Distance Effect

Numbers that are far apart (23 vs 87) are compared faster than close numbers (847 vs 851). This is called the distance effect in cognitive psychology.
