Cognitive and cognate-based treatments for bilingual aphasia: A case study

Two consecutive treatments were conducted to investigate skill learning and generalization within and across cognitive-linguistic domains in a 62-year-old Spanish-English bilingual man with severe non-fluent aphasia. Treatment I was a cognitive-based treatment that emphasized non-linguistic skills, such as visual scanning, categorization, and simple arithmetic. Treatment 2 was a lexically based treatment that trained cognates (cross-linguistic word pairs that are similar in meaning and form, such as rosa/rose) and non-cognates (cross-linguistic word pairs with shared meaning but different forms, such as mesa/table). Treatment 1 resulted in modest gains in both Spanish and English. Treatment 2 resulted in improved naming for non-cognates as well as cognates within each language. However, the generalization of gains from Spanish to English was apparent only for cognate stimuli. (C) 2004 Elsevier Inc. All rights reserved.
