Benefits
- Trains cognitive flexibility and set-shifting
- Strengthens executive function under changing demands
- Improves your ability to detect and adapt to new rules
- A brisk, engaging mental warm-up
The science
The Wisconsin Card Sorting Test is a classic measure of set-shifting and executive function. Practising rule changes exercises the prefrontal processes behind flexible, adaptive thinking.
