a collaborative knowledge base characterizing the state of current thought in Cognitive Science.
The participant is presented with stimulus cards with shapes on them. The cards differ in color of the shapes, number of the shapes, and the form of the shapes. The participant is asked to sort these cards into two piles. The participant is not told what stimulus dimension to use in order to sort the cards, but the administrator tells the participant if a particular match is correct. During the test, the sorting rules are changed and the participant must discover the new sorting rule in order to be successful.

CONTRASTS

In the Cognitive Atlas, we define a contrast as any function over experimental conditions. The simplest contrast is the indicator value for a specific condition; more complex contrasts include linear or nonlinear functions of the indicator across different experimental conditions.

INDICATORS

An indicator is a specific quantitative or qualitative variable that is recorded for analysis. These may include behavioral variables (such as response time, accuracy, or other measures of performance) or physiological variables (including genetics, psychophysiology, or brain imaging data).


User Discussion


"This one turns out to be tricky. What I have done is to code each category of error as a "condition" - even though these are not proper experimental conditions, they are like conditions in that they lead to different measures of performance. The reason I need to do this is that assertions link to contrasts, not to indicators."

"I have edited the description to simply describe the task and not to claim that it involves any particular mental function (such as "task switching"). To note that WCST measures task switching, you should create an assertion that links these two concepts, which I have also done. "

REVISION 2

Definition contributed by DLau about eight years ago:The Wisconsin Card Sorting test measures a person's task-switching ability. The participant is presented with stimulus cards with shapes on them. The cards differ in color of the shapes, quantity of the shapes, and design. The participant is then given an additional set of cards and asked to match each of these with one of the stimulus cards. The participant is not told how to match the cards, but the administrator tells the participant if a particular match is correct. During the test, the rules are changed and the participant must discover the new matching rule in order to be successful.
