Verbal Fluency as measured by phonemic and semantic tests (i.e. Controlled Oral Word Association Test COWAT; Benton & Hamsher, 1989 )

With phonemic fluency tests, subjects must produce orally as many words as possible beginning with a specified letter (e.g. FAS) during a fixed period, usually 1 minute. With semantic fluency tests, subjects must produce orally as many words as possible in common categories as, animals, vegetables, boys or girl names, during a fixed period, usually 1 minute.

Internal reliability coefficients for FAS and CFL phonemic fluency is .83 (Ruff, Light, Parker, & Levin, 1996) . Test retest reliability coefficients are typically above .70 for both phonemic and semantic fluency (Dikmen et al., 1999) a,c

Factor analysis studies suggest that phonemic and semantic fluency tests load on attention control/working memory functions. Subjects who perform well on working memory tasks also achieve high scores on semantic and phonemic fluency tasks (Rosen & Engle, 1997) a,c

Delis-Kaplan Executive Function System (DKEFS; Delis, Kaplan, & Kramer, 2001 )

Designed to detect forms of executive dysfunction and includes 9 tests that derive from existing experimental and clinical findings: Trail Making Test, Verbal Fluency Test, Design Fluency Test, Color-Word Interference Test, Sorting Test, Twenty Questions Test, Word Context Test, Tower Test, and Proverbs Test. It is a flexible battery and tests may be administered individually or in combination with other DKEFS tests.

Internal reliability coefficients range from inadequate or less than .60 for Trial Making Conditions 1 - 4, Verbal Fluency Category Switching, and Twenty Questions to as high as .80 to.90 for FAS Verbal Fluency. Test retest reliability coefficients also range from inadequate or less than .60 for Design Fluency, Sorting Test, Twenty Questions and Tower Test to adequate (.70 to .79) for Color-Word, Word Context, and Proverbs Testa,c

Convergent validity of the DKEFS with the WCST, with correlations in the moderate range (.31 - .59) between the Number of Categories Completed on the WCST and various measures from the nine tests of the DKEFSa,c
