The Wisconsin Card Sorting Test

The Wisconsin Card Sorting Test (WCST) is a psychological assessment that measures a person's ability to think flexibly, solve problems, and adapt to changing rules. During the test, individuals sort cards based on different criteria, like color, shape, or number, which they learn through feedback. The rules change unexpectedly, requiring participants to adjust their sorting strategies without explicit instructions. The test evaluates cognitive skills such as executive functioning, flexibility, and learning from mistakes, providing insights into brain function affected by conditions like brain injury, schizophrenia, or other neurological issues.
