Real Life Examples of Cognitive Deficits Assessed by the WCST

🧠 Quick Study Guide

• 📝 The Wisconsin Card Sorting Test (WCST) assesses executive functions like cognitive flexibility, abstract reasoning, and problem-solving.
• 🚦 The test involves sorting cards based on different criteria (color, form, or number) that change without warning.
• 🚫 A cognitive deficit is indicated by perseverative errors - continuing to sort based on a previously correct rule after it has changed.
• 💡 Real-life examples include difficulty adapting to new routines, trouble switching between tasks, or struggling to learn from mistakes.
• 📈 Scoring on the WCST considers the number of categories achieved, perseverative errors, and non-perseverative errors.
• 🧑‍⚕️ The WCST is used in diagnosing conditions like frontal lobe damage, schizophrenia, and ADHD.
• 🧮 No specific formulas are used; rather, the test is qualitative, measuring patterns of responses and errors.
