The Wisconsin Card Sorting Task (Classification Task) is a task based on neuropsychological principles, like abstraction ability, conceptualization, failure to maintain set and perseveration. This task is not the actual Wisconsin Card Sorting Test, but instead it is a computer-based task and different in a number of aspects.
The four stimulus cards are shown on the top row of the screen. The deck of 128 response cards is shown on the bottom row. The subject is instructed to type the number of the stimulus card the response card belongs to. Hereafter the response card is placed beneath the stimulus card. The subject then gets feedback from the computer by showing “CORRECT” or “INCORRECT” on the screen and an accompanying high or low beep. The test proceeds until 6 shifts of categories have taken place or until the deck of response cards is exhausted.
