Abstract

This retrospective cohort study examined the relationship between a continuous measurement of bilingual engagement (operationalized as language entropy) and cognitive aging in regional minority language speakers. We drew Frisian–Dutch bilinguals (n = 7,448) and Low Saxon–Dutch bilinguals (n = 10,114) from the Lifelines Cohort Study and included participants aged 20–80, enabling an adult lifespan perspective. Cognitive functioning was measured using the Cogstate Brief Battery, which assesses processing speed, attention, working memory and recognition memory. We did not observe a robust relationship between bilingual engagement and cognitive functioning. Our results suggest that bilingual engagement does not play a key role in processing speed, attention, working memory and recognition memory performance in Frisian–Dutch and Low Saxon–Dutch bilinguals. Implications for the bilingual engagement measurement and potential investigations into regional minority language bilingualism and cognition are discussed.

成年人一生中的双语参与和认知：来自荷兰北部地区少数民族语言使用者的见解

本回顾性队列研究考察了区域少数民族语言使用者连续测量双语参与（语言熵）与认知老化之间的关系。我们从生命线队列研究中抽取了弗里斯兰-荷兰双语者（n = 7,448）和低撒克逊-荷兰双语者（n = 10,114），并纳入了年龄在20-80岁之间的参与者，以实现成人寿命的视角。认知功能通过认知状态简短电池测试，评估处理速度、注意力、工作记忆和识别记忆。我们没有观察到双语参与和认知功能之间的牢固关系。我们的研究结果表明，双语参与在弗里斯兰-荷兰语和低撒克逊-荷兰语双语者的加工速度、注意力、工作记忆和识别记忆表现中并不起关键作用。讨论了双语参与测量的意义以及对区域少数民族语言双语和认知的潜在调查。
