Wisconsin card sort test
From Psy3241
The Wisconsin Card Sorting Test is a neuropsychological test of abstract thinking, planning, and the ability to alter mental sets as circumstances require.
How It Works
The Wisconsin Card Sorting Test consists of a special deck of 128 cards differing in color, form, and number of forms on each card (e.g. four blue circles, three green stars, one red triangle, etc.). The person being tested is provided with four different cards layed out in front of them by the person administering the test. They are given the remaining cards in the deck and asked to match each of the cards in the deck with its corresponding appropraite card, in one of the four piles previously layed out. They are not told how to match the cards (whether by color, shape, or number), but they are provided with feedback by the administer, as to whether they've matched the cards correctly. Also, after a few trials, the administer will change the "rule" that the cards are being matched by (color, shape, or number), and the person being tested has to quickly shift their mindset to accomodate the new "rule" (see example below).
