What does the card sorting task measure?

Description. The Wisconsin Card Sorting Test (WCST) is a measure of executive functioning, which measures one’s ability to develop abstract concepts (abstract reasoning) and shift between sets (mental or cognitive flexibility and problem solving).

Does the Wisconsin Card Sorting Test measure Prefontral function?

The results show that WCST performance evokes conspicuous physiological changes over frontal as well as posterior brain regions. These findings strongly suggest that WCST scores cannot be regarded as valid nor specific markers of prefrontal lobe function.

What kind of test is Wisconsin Card Sorting 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 is the modified card sorting test?

The Modified Card Sorting Test (MCST), a shortened version of the Wisconsin Card Sorting Test, proposed by Nelson in 1976 is a neuropsychological test that is widely used in clinical settings for the evaluation of executive functions in patients with focal, traumatic and degenerative brain diseases.

Is the Wisconsin Card Sorting Test a criterion referenced test?

I am struggling as i know the test consists of 3 criterions (colour, shape or number) but there are tests i have seen online in which test scores were compared against a sample and some were not. Wisconsin Card Sorting Test (WCST) is a neuropsychological test of “set-shifting”. It is a test of cognitive reasoning.

What are Nonperseverative errors?

Perseverative error occurs when the participant continues with the same response strategy following a rule switch. This type of error is regarded as a failure to inhibit a prepotent response. Non-perseverative errors are generally considered to be random.

What does a low score on the Wisconsin Card Sorting Test show?

The WCST is a neuropsychological instrument used to measure the executive functions, reportedly sensitive to brain dysfunction affecting the frontal lobes. It is a screening instrument to evaluate the health status of individuals. A cut-off score of 2 or above implies pathology.
