Verbal Fluency
You get one starting letter and a clock. Type real words that start with that letter. Repeats and tiny fragments do not count. Short is 45 seconds. Long is 60. The letter is fresh each run so you cannot reuse a memorised list.

You get one letter. Type real words that start with it. Repeats and fragments under 3 letters do not count.
Pick a length
Short is a quick check. Long is the full run. Your best for each is stored on this device.
What this measures
Letter fluency (a FAS-style task) measures how fast you can search your verbal store and dump items under a rule. Clusters (salt, sand, sea) then switches (to a new cluster) are the usual strategy. People stall when they stay inside one cluster too long or when they reject decent words as not clever enough. This is a language-plus-executive task, not a vocabulary quiz. We count unique words of three or more letters. We do not grade rarity.
Where this shows up in real life
Dumping words under a rule is brainstorming and exam-essay start-up. Cluster, then switch category when the well runs dry.
How to improve
- Sweep categories: food, names, places, verbs, then objects.
- Do not hunt for clever words. Simple words score the same.
- If you freeze, add -ing or a plural of a word you already used only if it is a new string. Repeats still fail.
- Type fast, fix later. The clock cares about count, not spelling beauty, but junk strings will not count.
Frequently asked questions
What is a good fluency score?
Around 14 unique words in a minute is typical for a random letter. Low 20s is strong. Compare letters across days. Some letters are richer.
Do names and places count?
Yes, if they are at least three letters and not a repeat. Keep them coming rather than debating the rule.
Why do I blank after ten words?
You emptied one cluster. Switch category on purpose. The blank is usually a strategy stall, not an empty vocabulary.
