Verbal fluency is one of the first and most important cognitive functions that deteriorate during the aging process. Verbal fluency is defined as the skill and speed of finding words and finding semantic and phonetic connections between words. One of the most important factors in verbal fluency is bilingualism. Therefore, the current study aimed to investigate the effect of bilingualism on the verbal fluency of the elderly in Iran. A total of 12 normal elderly bilingual (Arabic-Persian) speakers and 12 normal elderly monolingual (Persian) speakers participated in this comparative-analytical study. To assess verbal fluency, two semantic and phonetic fluency tasks were used. Data were analyzed using the Wilcoxon-Mann-Whitney tests. The results obtained from the comparison of phonetic fluency and semantic fluency of native languages of the two groups showed a better performance of monolingual participants in semantic fluency and phonetic fluency tasks in Persian language compared to the Arabic bilingual elderly. No difference was observed in verbal fluency of Persian monolinguals and bilinguals. However, in bilingual elderly participants, faster retrieval was observed in Persian language than in Arabic. This can be considered in assessment and treatment measures for Arabic-Persian bilinguals.
语言流畅性是衰老过程中最早且最重要的认知功能之一，会逐渐退化。语言流畅性被定义为查找单词以及在单词之间找到语义和语音联系的技能与速度。双语能力是语言流畅性的最重要因素之一。因此，本研究旨在调查双语能力对伊朗老年人语言流畅性的影响。共有12名正常的老年双语（阿拉伯语 - 波斯语）使用者和12名正常的老年单语（波斯语）使用者参与了这项对比分析研究。为评估语言流畅性，使用了两项语义和语音流畅性任务。数据采用Wilcoxon - Mann - Whitney检验进行分析。两组母语的语音流畅性和语义流畅性比较结果显示，与阿拉伯语双语老年人相比，单语参与者在波斯语的语义流畅性和语音流畅性任务中表现更好。波斯语单语者和双语者在语言流畅性方面未观察到差异。然而，在双语老年参与者中，波斯语的检索速度比阿拉伯语更快。这在阿拉伯语 - 波斯语双语者的评估和治疗措施中可以加以考虑。
