Wisconsin Card Sorting Test
Wisconsin Card Sorting Test
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. Grant and Esta A. Berg in 1948.
Pronunciation
Wisconsin: /wɪˈskɒnsɪn/ Card Sorting Test: /kɑːrd ˈsɔːrtɪŋ tɛst/
Etymology
The test is named after the state of Wisconsin, where it was first developed at the University of Wisconsin. The term "Card Sorting" refers to the task that the test involves.
Description
The WCST uses a deck of 64 cards, each of which has a figure printed on it. These figures vary in color, form (shape), and number. The test subject is asked to match each card from the deck to one of four stimulus cards. The matching criterion is not told to the subject, but they are informed whether a particular match is right or wrong. The test measures the subject's ability to form abstract concepts and shift these concepts in response to changing rules.
