- Human problem-solving research often focuses on static problems, but real-world problems change, requiring strategy adaptation.
- The Wisconsin Card Sort Test (WCST) was developed by Grant and Berg (1948) to study how people adapt to changing problem-solving rules.
- Participants match cards based on attributes like color, number, or shape, with the sorting rule changing during the test.
- The test measures adaptability by tracking correct sorts, errors, and perseveration (sticking to old rules after they change).
- Originally used to assess prefrontal lobe disorders, the WCST is now cautioned against as a sole indicator of frontal lobe damage.
- Two versions exist: a short 24-card version and the original 64-card version, differing in rule change frequency and deck size.
- Key variables tracked include card attributes, sorting accuracy, response time, and correct sorts in a row.
