Method
Initially, a number of stimulus cards are presented to the participant. The participant is told to match the cards, but not how to match; however, he or she is told whether a particular match is right or wrong. The original WCST used paper cards and was carried out with the experimenter on one side of the desk facing the participant on the other. Since the early 1990s, however, computerized versions of the task have been available, the most recent version being the Microsoft Windows-compatible version 4.0. The latter has the advantage of automatically scoring the test, which was quite complex in the manual version. The test takes approximately 12–20 minutes to carry out and generates a number of psychometric scores, including numbers, percentages, and percentiles of: categories achieved, trials, errors, and perseverative errors.

Famous quotes containing the word method:
“Unlike Descartes, we own and use our beliefs of the moment, even in the midst of philosophizing, until by what is vaguely called scientific method we change them here and there for the better. Within our own total evolving doctrine, we can judge truth as earnestly and absolutely as can be, subject to correction, but that goes without saying.”
—Willard Van Orman Quine (b. 1908)
“The method of scientific investigation is nothing but the expression of the necessary mode of working of the human mind. It is simply the mode in which all phenomena are reasoned about, rendered precise and exact.”
—Thomas Henry Huxley (1825–95)
“You know, I have a method all my own. If you’ll notice, the coat came first, then the tie, then the shirt. Now, according to Hoyle, after that the pants should be next. There’s where I’m different. I go for the shoes next. First the right, then the left. After that, it’s every man for himself.”
—Robert Riskin (1897–1955)
