Bilingual performance on Object and Action Naming Test: Preliminary normative data in Spanish and English

The U.S. has a growing Spanish-English bilingual elderly population subject to stroke and aphasia. Naming deficits are characteristic of all types of aphasia, yet bilingual normative data for verb and noun naming on commercial tests are not available. The current study aims to evaluate, and determine predictive factors for, performance on the Object and Action Naming Battery. Preliminary results for 40 Spanish-English bilingual adults resulted in English proficient, Balanced Bilingual, and Spanish proficient groups. English was named more accurately than Spanish with no difference in naming nouns as compared to verbs. Self ratings of language abilities were highly correlated with naming accuracy across languages.
