Thurstone Word Fluency Test

The Thurstone Word Fluency Test, also known as the Chicago Word Fluency Test (CWFT),[1] was developed by Louis Thurstone in 1938.[2] This test became the first word fluency psychometrically measured test available to patients with brain damage.[3] The test is a used to measure an individual's symbolic verbal fluency.[4][5][6] The test asks the subject to write as many words as possible beginning with the letter 'S' within a 5-minute limit, then as many words as possible beginning with letter 'C' within 4 minute limit. The total number of 'S' and 'C' words produced, minus the number of rule-breaking and perseverative responses, yield the patients' measure of verbal fluency.

The CWFT is used as one of the measures of brain's frontal lobe function. A related test, the COWAT (Controlled oral word association test), is part of the Halstead-Reitan Neuropsychological Battery.
