摘要：Single-system theories of multilingual language representation would predict that treating language impairment resulting from focal brain damage in one language of multilinguals can generalize and lead to positive effects also in the untreated languages. Currently published results have been mixed, showing selected, modest cross-language facilitation. Whether cross-language facilitation is obtained depends, in part, on relative language proficiency and order of language acquisition. For example, positive change was found in untreated languages for participants who were equally proficient in their treated and untreated languages (Edmonds & Kiran, 2006), but not for the first-acquired language (LI) when another, non-Ll was treated (Goral, Levy, & Kasti, 2010; Miertsch, Meisel, & Isel, 2009). Moreover, the opposite pattern, i.e., negative cross-language effects - with worse performance in the untreated languages following treatment - has also been reported (Abutalebi et al., 2009). We report here data from three multilingual individuals with aphasia who show both patterns - crosslanguage facilitation and inhibition - from their treated to untreated languages.
