Which area of the brain is critical to performance on the Wisconsin Card Sorting Task?
prefrontal function
For over four decades the Wisconsin Card Sorting Test (WCST) has been one of the most distinctive tests of prefrontal function.
What does the Wisconsin Card Sorting Task measure?
The Wisconsin Card Sorting Test (WCST), originally developed to assess abstract reasoning ability and the ability to shift cognitive strategies in response to changing environ-mental contingencies,1,2 is also considered a measure of the executive functions.
How do you play Wisconsin Card Sort test?
In Wisconsin Card Sorting Test you need to match a card with one of the four cards on the buttons. After the selection you will get feedback whether the card’s selection is correct or not. If not, you have to apply different rule and match again. The rules are three – by color, by shape and by count/number.
Who developed the Wisconsin Card Sorting Test?
Grant and Berg
In 1948, Grant and Berg published their now very famous Wisconsin Card Sorting Test. It is a test of cognitive reasoning. Later, in the 1960s, Milner started to use this cognitive test to assess patient’s level of brain damage to the prefrontal cortex.
How do you conduct a card sorting exercise?
Conducting a Card Sort
- Choose a set of topics. The set should include 40–80 items that represent the main content on the site.
- User organizes topics into groups.
- User names the groups.
- Debrief the user.
- If needed, ask the user for more-practical group sizes.
- Repeat with 15–20 users.
- Analyze the data.
How many participants do you need for card sorting?
Tullis and Wood recommend testing 20–30 users for card sorting. Based on their data, my recommendation is to test 15 users.
Why does a psychologist administer the Wisconsin Card Sorting Test?
Since 1948, the test has been used by neuropsychologists and clinical psychologists in patients with acquired brain injury, neurodegenerative disease, or mental illness such as schizophrenia. It is one of several psychological tests which can be administered to patients to measure frontal lobe dysfunction.
How many users are enough for a card sorting study?
How do you perform card sorting?
Who can administer WCST?
A qualified examiner must proctor the administration of the WCST and WCST-64. No other individuals should be present unless an observer or another facilitator is necessary. The client’s activity should be closely monitored, and any attempts to open additional computer windows should be stopped immediately.
Is card sorting qual or quant?
Is card sorting qualitative or quantitative in nature? In it itself, card sorting is a quantitative process. The main quantitative data output from a card sort is a set of similarity scores that measures the similarity of how users grouped their sets of information.
What is the process of card sorting?
In an open card sort, users are free to assign whatever names they want to the groups they’ve created with the cards in the stack. Closed card sorting is a variation where users are given a predetermined set of category names, and they are asked to organize the individual cards into these predetermined categories.
How long does the WCST take to administer?
The test takes approximately 12–20 minutes to carry out and generates a number of psychometric scores, including numbers, percentages, and percentiles of: categories achieved, trials, errors, and perseverative errors.
What type of test is Wisconsin Card Sorting?
neuropsychological test
The Wisconsin Card Sorting Test (WCST) is a neuropsychological test that is frequently used to measure such higher-level cognitive processes as attention, perseverance, WM, abstract thinking, CF, and set shifting.
What type of research is card sorting?
Definition: Card sorting is a UX research method in which study participants group individual labels written on notecards according to criteria that make sense to them.

Carina Coulacoglou, Donald H. Saklofske, in Psychometrics and Psychological Assessment, 2017 The Wisconsin Card Sorting Test (WCST) is a neuropsychological test that is frequently used to measure such higher-level cognitive processes as attention, perseverance, WM, abstract thinking, CF, and set shifting.
Is the Wisconsin Card Sorting Test copyrighted in the US?
This task is not the actual Wisconsin Card Sorting Test, as copyrighted in the US, but instead it is a computer-based task that is inspired by the original work by Berg, and different in a number of important aspects. If you want to have the original exact Wisconsin Card Sorting Test, please find the publisher’s information.
What is Milner’s Card Sorting Test?
Later, in the 1960s, Milner started to use this cognitive test to assess patient’s level of brain damage to the prefrontal cortex. The original Wisconsing Card Sorting Test was developed for use with patients with brain damage. It is probably not so useful to compare executive control function in healthy people.
What is the washing Card Sorting Test?
The original Wisconsing Card Sorting Test was developed for use with patients with brain damage. It is probably not so useful to compare executive control function in healthy people. Instead, you may better go for one of the task switching or N-back tasks . In short, in the WCST, people have to classify cards according to different criteria.
