Bilingual aphasia: semantic organization, strategy use, and productivity in semantic verbal fluency.

A semantic verbal fluency task (Animals, Foods) was administered to 16 aphasic, bilingual adults in French and English. Each subject was tested twice in each language. The two goals of the study were to compare performance across languages and to determine the effect of a deliberate grouping strategy on productivity. All subjects claimed approximately equal prestroke abilities in both languages. The number of words subjects produced was not significantly different in the two languages. Semantic organization across languages was also similar on Test 1. On Test 2, 8 subjects were instructed to group items by subcategory and 8 simply repeated the task. There was no consistent between-group difference in number of correct words or in the semantic organization of responses. Implications for the clinical use of verbal fluency tests and for further research into bilingual lexicosemantic systems are discussed. Copyright 1998 Academic Press.
