About this test: The Brain Age Test bundles four short mini-tasks into one session of roughly two to three minutes, then converts your combined speed and accuracy into a single brain age estimate between 20 and 80. Lower is better, and the number is meant for fun and self-tracking — it is not a medical, diagnostic, or clinical measure of any kind.
The four tasks:
- Reaction Speed: Tap the circle the instant it turns green. Five trials; your typical (median) reaction time counts, so one slow tap will not ruin the score. Tapping while the circle is still red counts as a false start — the trial restarts and each false start adds a small penalty to your reaction sub-score.
- Quick Math: Ten simple arithmetic problems with three answer choices each. Both speed and accuracy count.
- Number Memory: A number flashes briefly, then you pick it from four similar options. Three rounds with longer numbers each time.
- Color Focus: A color word appears printed in colored ink — pick the ink color, not what the word says. Eight trials of this classic interference challenge.
How the estimate works: Each task produces a sub-score on the same 20–80 age scale — faster reactions, quicker correct answers, and more accurate recall all push it lower. Your brain age is the average of the four sub-scores, and the results screen shows each one so you can see which task helped or hurt.
Tips:
- Rest your finger near the screen or mouse button during the reaction task — travel distance adds real milliseconds.
- In the memory rounds, reading the number aloud in your head as chunks (two or three digits at a time) is much stronger than trying to photograph it.
- In color focus, ignore the meaning entirely — focus on the ink as if the word were in a language you cannot read.
- Retest at the same time of day for a fair trend line; scores naturally dip when you are tired.
