What problem does it solve?
The Wisconsin Card Sorting Test (WCST) is one of the most-used clinical tests of executive function. It measures your ability to discover and adapt to changing rules — a fundamental aspect of cognitive flexibility.
Sort cards into piles by an unknown rule (color? shape? count?). When you get it right, we change the rule without telling you. Adapting is the test.
What makes this one different
We log perseveration rate — how often you keep using the old rule after it changes — and trials to first correct after each rule switch. These two metrics are more diagnostic than raw accuracy.

The Wisconsin Card Sorting Test (WCST) is one of the most-used clinical tests of executive function. It measures your ability to discover and adapt to changing rules — a fundamental aspect of cognitive flexibility.
Perseveration rate below 15% is good. Above 30% suggests you're holding onto old rules.
Trials to first correct under 4 is good. Above 8 means you take a while to discover new rules.
You don't — that's the point. You'll start getting "wrong" feedback, and you have to figure out why.
Because giving specific feedback would teach you the rule. Real WCST only says right or wrong.
