The Wisconsin Card Sorting Test (WCST) is a cognitive test used to assess cognitive flexibility, reasoning, and the brain's adaptability. It has been a key tool in psychology since its development in 1948 by Grant and Berg. The task evaluates an individual's ability to adjust to changing rules and measure cognitive control in the prefrontal cortex.
During the WCST, participants classify cards based on color, shape, or number. The classification rule changes after every 10 cards, challenging the participants' ability to adapt. The test is commonly used in cognitive research, including studies of ADHD, brain health, and cognitive disorders.
In this task, you need to match a card to one of four cards based on its shape, color, or number.
Example: Please look at the following shapes.
Based on the instructions, select the card among the four above that matches the condition of the card below.
Explanation:
If the task asks you to match by color, select the first card;
If the task asks you to match by shape, select the second card;
If the task asks you to match by number, select the fourth card.
The rules will change periodically, so you need to adjust your matching strategy based on feedback.
There are 60 trials, and after each trial, you will receive feedback to help you understand the current matching rule.
