Annotation	Paraphasia refers to verbal impairments in aphasia, and pertains to the use of an unexpected word for the originally intended word. In this study, Paraphasias on the Cognistat (Northern California Neurobehavioural Group, 1995) memory sub-test were examined in a sample of geriatric veterans (average age 77). "Robert" and "parrot" were the most frequently occurring paraphasias for the target words robin, carrot, piano and green. Paraphasia frequency and type varied by ethnic group: European-Americans were less likely to have a paraphasia; Hispanic-Americans were more likely to have a "Robert" or "parrot" paraphasia; and African-Americans were more likely to have a paraphasia other than "Robert" or "parrot". Additional research is needed to determine the cause of paraphasias on the Cognistat and the clinical significance of paraphasias for each ethnic group. (KJ/RH).
