The Professional Manual for the WCST was written by Robert K. Heaton, Gordon J. Chelune, Jack L. Talley, Gary G. Kay, and Glenn Curtiss.[13] Since 1948, the test has been used by neuropsychologists and clinical psychologists in patients with acquired brain injury,[11][14][15] neurodegenerative disease, or mental illness such as schizophrenia.[13][16] It is one of several psychological tests which can be administered to patients to measure frontal lobe dysfunction.[17][18] When administered, the WCST allows the clinician speculate to the following frontal lobe functions: strategic planning, organized searching, utilizing environmental feedback to shift cognitive sets, directing behavior toward achieving a goal, and modulating impulsive responding.[21][22] The WCST, relies upon a number of cognitive functions including attention, working memory, and visual processing.
