Applicability of the "An Object and Action Naming Battery" in Brazilian Portuguese

PURPOSE: To verify the performance of a sample of Brazilian subjects in the "An Object and Action Naming Battery" (OANB), according to schooling; and to describe the main error types in nouns and verbs naming. METHODS: The OANB was applied in 100 healthy subjects, divided in two groups (GI: four to eight years of schooling; and GII: above nine years). RESULTS: There were correct answers for 97.6% for nouns and 98.0% for verbs. There were statistically significant differences between the groups in the number of correct answers for nouns and verbs (p<0.0001) and in the proportion of semantic errors for verbs (p=0.0160), with less educated subjects performing poorer than higher educated ones. CONCLUSION: The OANB may be used in adult Brazilian Portuguese native speakers. The group with higher education had higher scores; both groups had a higher proportion of "semantic errors" for verbs and nouns.
