In two different studies (26, 27), schizophrenic patients and depressives, who exhibited comparable deficits, performed worse than normal controls in WCST. ome researches showed that depression may affect neuropsychological test performances (28, 29).
What does the Wisconsin Card Sorting Test diagnose?
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 are Perseverative errors WCST?
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.
Why is the Wisconsin Card Sort Task considered to measure cognitive flexibility?
The Wisconsin Card Sorting Test (WCST) is a neuropsychological test of “set-shifting”, i.e. the ability to display flexibility in the face of changing schedules of reinforcement. The WCST was written by David A.

What are conceptual level responses WCST?
Conceptual level responses (CLR: All consecutive correct responses including ambiguous correct responses that occurred in runs of three of more) and percent CLR (percentage of correct response occurring in runs of three or more) were also assessed during the test procedure.
What is the modified card sorting task?
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.
What brain areas are involved in completing the Wisconsin card Sorting Task?
These structures make up the prefrontal cortical basal ganglia loops (Alexander et al., 1986). Significant activation was also found, bilaterally, in the rostral anterior cingulate cortex (area 32), lateral premotor cortex (area 6), posterior parietal cortex (areas 7 and 40), and prestriate cortex (area 19).
What does perseverance error mean?
According to the theory of cognitive development, as part of a childs development of object permanence, what does perseverance error refer to? The mistake of looking in a place an object was previously found.
What does trail making test measure?
The test can provide information about visual search speed, scanning, speed of processing, mental flexibility, as well as executive functioning. It is sensitive to detecting cognitive impairment associated with dementia, for example, Alzheimer’s disease.
What is set shifting in psychology?
Set-shifting refers to the ability to move back and forward between different tasks or mental sets, and is often used as a measure of cognitive flexibility. Patients with AN often have a rigid thinking style, which also involves eating and weight.
How is the WCST scored?
The WCST was scored on nine performance parameters (see Table 2) and reverse scored on some items (abstract thinking, cognitive focus, conceptual plasticity, attention, and concept formation). …

What are different card sorting approaches?
There are three types of traditional card sorts: open, closed, and hybrid. There are two testing facilitation approaches: moderated or unmoderated, discussed after the traditional types of card sorts.
Why is card sorting done?
Card sorting is a method used to help design or evaluate the information architecture of a site. In a card sorting session, participants organize topics into categories that make sense to them and they may also help you label these groups.
How many types of card sorting are there?
There are three types of card sorting you can choose from: Open card sorting: participants sort the cards by groups and then name the groups themselves. Closed card sorting: a moderator gives participants the defined categories to sort the cards into.
What is a superficial match?
Superficial match is a Card Sorting technique in which if there are large number of items to sort, then the participants can simply group the similar items or names together. Example: The number of color pencil items in a color pencil box are placed together in the same box regardless of the color of any pencil.
What is Hybrid card sorting?
With hybrid card sorts, participants are asked to sort cards into categories, but they can use both the categories provided by the researcher or create their own categories during the unmoderated task.
What is reverse card sorting?
Reverse card sorting
In a reverse card sort (more popularly called tree testing), an existing structure of categories and sub-categories is tested. Users are given tasks and are asked to complete them navigating a collection of cards.
Is card sorting a usability test?
Card sorting is a usability methodology that has been used by information architects for years to organize web designs and web content more effectively.
Is tree testing similar to card sorting?
Tree testing is an activity that requires participants to seek information, which is quite the contrast to card sorting — an activity that requires participants to sort and organize information. Each activity requires users to behave in different ways, so each method will give its own valuable results.
What is usability testing?
Usability testing refers to evaluating a product or service by testing it with representative users. Typically, during a test, participants will try to complete typical tasks while observers watch, listen and takes notes.
What is sanity testing?
Definition: Sanity testing is a subset of regression testing. After receiving the software build, sanity testing is performed to ensure that the code changes introduced are working as expected . This testing is a checkpoint to determine if testing for the build can proceed or not.
What is Localisation testing?
Essentially, localization testing is a technique to verify software behavior, accuracy, and suitability for specific locations and regions. This could be anything from a particular city to an entire country. The method tests how the software would behave when used in different areas.
What is black block testing?
Black box testing involves testing a system with no prior knowledge of its internal workings. A tester provides an input, and observes the output generated by the system under test.
What are different levels of testing?
There are generally four recognized levels of testing: unit/component testing, integration testing, system testing, and acceptance testing.
What is red box testing?
Red Box Testing: Also referred as acceptance testing. in which user/client apply any technique like black box testing, white box testing and gray box testing to accept the project. Yellow Box Testing: check against warning messages that weather the system throws the warning messages or not.
