Abstract
INTRODUCTION: Semantic Feature Analysis (SFA) therapy is a widely used approach for single-word naming treatment in monolingual and bilingual persons with aphasia (BiPWAs). There is evidence that SFA leads to naming improvements in both treated and untreated languages of BiPWAs. However, research on the generalization effects of SFA on narrative production is scarce. This study investigated the within- and cross-language generalization effects of SFA on narrative production and its relationship to naming gains in a group of L1-Russian-L2-Hebrew chronic-stage BiPWAs. METHODS: The study included two groups of BiPWAs. In the experimental group, ten individuals received one or two blocks of SFA, while ten participants who did not receive therapy served as a control group. We compared the changes in narrative production between the experimental and control groups and examined whether the narrative changes in the experimental group were related to naming gains. RESULTS: The results indicated that SFA generalized to narrative production in the experimental group. Within-language generalization was observed following SFA in L1, while cross-language generalization was found following SFA in both L1 and L2. CONCLUSION: Although SFA has the potential to generalize to narrative production in BiPWAs, this effect did not consistently align with the therapy gains in naming. To achieve greater within- and cross-language generalization effects, we recommend providing SFA in the L1 of BiPWAs.
